On July 25, 2019 NOAA Ship Reuben Lasker and its crew navigated slowly under the Golden Gate Bridge into San Francisco Bay. As the fog smothered entrance to the bay loomed ahead of us, I stood on the bow with the Chief Bosun and a few others listening to, of all things, sea shanties. We passed a couple of whales and a sea lion playing in the water, and we cruised right passed Alcatraz before arriving at our pier to tie up.
San Francisco did not disappoint! I walked a total of 20 miles that day stopping at Pier 39 to watch the sea lions, Ghirardelli Square to get chocolate ice cream, and Boudin Bakery to try their famous sourdough bread. I walked along the San Francisco Bay Trail, over the Golden Gate Bridge, and then back to the ship.
Later that evening I went out for dinner with three of the science crew and the restaurant had a couple of local items that I hold near and dear to my heart now – sardines and market squid. It felt like everything came full circle when I ordered the fried sardine appetizer and grilled squid salad for dinner after having caught, measured, and weighed so many of them on the ship. I never would have stopped before to think about the important role those little critters play in our food chain.
The first entry for this blog posted almost two months ago framed an introduction to a journey. Even though I’ve been back on land for three weeks now, I couldn’t quite bring myself to title this entry “The Journey Ends.” Instead it feels like the journey has shifted in a new direction.
I spent a lot of time on NOAA Ship Reuben Lasker thinking about how to integrate lessons from this project into my classroom and how to share ideas with other teachers in my district and beyond. Most of all this trip inspired me to reach out even more to my colleagues to collaborate and design instructional activities that push the boundaries of the traditional high school paradigm.
Weather at 1200 Pacific Standard Time on Monday 22 July 2019
When I walk outside onto the deck, the sky is a stunning shade of blue matching the color of Frost Glacier Freeze Gatorade. The sun is warm against my skin – I’m finally not wearing a jacket – and bright, but not so bright that I have to squint against the reflection of the water. I put my sunglasses on anyway since the polarized lenses help me see more defined colors in bright sunlight. The instruments show 15° Celsius right now with 25 knot winds. The horizon has a funny haze along its whole length even though the sky above me is absolutely clear. When I look over the long distance, I’m seeing cumulative aerosols – dust, water vapor, and other particles suspended in the air to form a haze along the horizon. I can’t see it directly above me even though it must be there.
One of the most beautiful things I’ve seen this whole trip, even when you take the coastline into account, are the squid. Never thought I’d write that sentence. But they sparkle and change colors! Last week we found a tiny octopus in something called a bongo tow (I’ll explain that in the science section). That little critter was even more awe inspiring. It had big turquoise eyes that reminded me of peacock feathers.
While I was in Newport, Oregon before the ship left, I was walking around Newport Marina and found a couple of guys painting a mural. The one who designed the mural is an art teacher at Newport High School. We started talking about his mural and the NOAA Teacher at Sea program. In addition to his career as an art teacher, Casey McEneny also runs his own art studio called Casey McEneny Art. The other guy helping him, Jason, has an art studio called Jay Scott Studios.
By painting the commissioned mural, he was connecting his career with his love of art and his community. His son even participated in the process by filling in a small portion of the mural while Casey worked on outlining the rest of it. Later he’ll go back and overlay the mural with color so it pops off the wall.
Ok, so the bongo tow. Do you remember as a kid (if you were a kid in the movies) when you used to run through fields of flowers catching butterflies in a butterfly net? I’m imagining a 6 year old girl with a flowing sundress. Well, take two oversized white butterfly nets and attach them to a metal frame that look like spectacles. Each hoop in this frame has a 71 centimeter diameter. These mesh nets each have a codend just like the trawl nets, except these codends are less than 1 foot long and are made out of extremely fine mesh. They’re designed to catch zooplankton – copepods, krill – and other smaller things that the net collects while traveling through the water column.
The juvenile octopus we found in the bongo tow last week was too difficult to identify at that young stage. It was only about 1 inch long. I searched through their identification books in the lab and tried to figure it out, but even the scientists said that the science community just doesn’t know enough yet about cephalopods (think octopus and squid species) to identify this beautiful creature until it’s an adult. We do know, since it has 8 arms and a fused mantle, that it’s at least an octopus and not a squid. Squid are not octopods, they’re decapods – in addition to the 8 arms they also have 2 long tentacles.
There are two species of octopus living in this area that look very similar even as adults. They are the Enteroctopus dofleini (Pacific Giant Octopus) and the Octopus rubescens (East Pacific Red Octopus). As adults, they’re both a dark red color almost like rust or brick. The artist I mentioned earlier, Casey, included a Pacific Giant Octopus in his mural at Newport Marina. But those are just two of many, many species of octopods in this area. Our little guy is probably neither of those. Still, I’m hoping it is a baby Octopus rubescens since they have a high density of chromatophores that make them sparkle!
The chromatophores are cells that both reflect light and contain different colors (pigment). They come in all different patterns and are distinct enough to use as identification tools for different species. They can be individually large or small and show up either in dense patches or scattered like freckles. Octopus and squid species contract and expand these special cells to change color based on necessity, if they need camouflage for example, or it’s thought that they even use color to communicate their mood. I’ve seen them sparkle in brilliant colors like a kaleidoscope but that’s probably, unfortunately, an expression of their agitated state since we’re catching them.
While there’s no way to tell exactly what they’re thinking, it is well known that octopus species are highly intelligent compared to other animals found in the ocean. They are curious, they sometimes play pranks on divers, and they seem to be more intentional than fish in their actions. Their intelligence made me think they’d have long lives, that they gained experience and personality over time, but octopus species typically only live a few years. Females will usually only reproduce once in their short life spans.
There are so many ways to connect cephalopods to the classroom! First, research shows octopus species may plan ahead and that they can learn and adapt to their surroundings. They’re problem solvers. They’re curious by nature. How often do I wish my students were more curious about learning and literacy! By reading about the resiliency and learning capabilities of an octopus, maybe it will inspire my students to see themselves as more capable of persevering through difficult challenges and adapting their learning styles to meet the needs of different disciplines. I can drive home the point that studying for biology might not look the same as studying for their upcoming test in civics, and that the more academic learning tools they have to employ from their toolbox, the more they’ll be able to master this whole “being a student” thing. If you’re at a loss for how to bring an octopus into the classroom, try starting with this activity from the NY Times Learning Network called Learning with “Yes, the Octopus is Smart as Heck. But Why?”.
Casey, the art teacher from Newport High School, shared an interesting activity from his art class. He recommends using images of zooplankton under microscope (we found plenty of these in our bongo tow!) to inspire abstract art projects similar to how Carl Stuwe intertwined science with art at the beginning of the 20th century. English teachers could share the same images to get students writing creative fiction or a mini lesson on imagery. Science and art provide a natural blend and plenty of opportunities for teachers to collaborate and combine our instructional force so we can integrate important concepts across the disciplines.
As a literacy teacher, I can’t help but think about how awesome it would be to teach my students the Latin prefixes and root words that are commonly used to name sea creatures. Names like Doryteuthis opalescens, Rossia pacifica, Octopus californicus, or Thysanoteuthis rhombus. Then, let them loose to name, design, describe, and share their own octopus species – yet to be discovered! While I’m sure their imaginations would come up with some elaborate ideas, few things are ever as fantastical as reality. Check out the Vampyroteuthis infernalis living in the deep, dark depths of the ocean.
We wouldn’t have found this creature or been able to capture its image without technology like Remotely Operated Vehicles (ROVs) and underwater submersible vehicles. There are clearly ways to link instruction to technology courses in addition to art, science, and literacy. Maybe students could take a sea creature that already exists and use mixed media to present an artistic representation of it like the Oregon Coast Aquarium did for their Seapunk exhibit. They could get their mixed media supplies from scrap leftover in the tech wing.
Weather at 1300 Pacific Standard Time on Friday 19 July 2019
We’re rockin’ and rollin’ out to sea. This transect carries us 138 miles off the coast, and the winds are steady at 35-40 knots. Waves keep slapping up over the deck outside our lab. I’m watching it through a window. As the boat rocks back and forth, the full frame of the window alternates between powder blue sky and foamy, purple blue sea. We’ve started tacking (zig-zag) through the water so we can minimize the effect of the roll. But with 12 foot waves, it’s only a minimal aide to our comfort. We’ve rolled a full 35° and pitched about 15° throughout the day. Though I haven’t been outside to compare it to other days, the temperature on the monitor reads 17° Celsius. With the strong breeze, I must assume it feels colder than that outside.
Let’s talk about seasickness. It rattles everyone from the novice to the career fisherman. It depends on sea state and state of mind. The rougher the weather, the more people seem to feel woozy and nauseated. There’s no pattern I can see between people who are new versus people who have been at this a while. It doesn’t seem to get any better with experience. Almost everyone I’ve talked to has taken some sort of motion sickness medication at some point over the last three weeks for some reason. I’d like to believe that the more healthy you are going into it – physically fit, decent diet – the more stoic your stomach will be, but I haven’t seen a connection in that respect either.
All I know, is that some people are sick and some are not. Differences? Medication is one. We’re all taking different types. Of those I’ve seen wearing a patch, they are not feeling well. I’ve been taking Bonine and I’ve felt great the whole trip. Bonine is a chewable tablet that you only need once each day. I took it for the first few days, stopped taking it, then started again when the weather forecast looked bleak. I’ve found that if it’s in my system before the waves get choppy, then I fair well through the storm.
Another difference is attitude. Of the people who are not feeling well, those who smile and take it in stride are able to spend more time out of their staterooms focused on the task at hand – whatever their role may be. Distraction is a bonus. It’s not like you have a virus that is running its course. If you can get yourself good and distracted, it eases the symptoms and provides some relief.
And also, sleep. There is a definite connection between quality of sleep and symptoms of sea sickness. I’ve seen a solid nap cure a couple people of their ails. Thankfully, due to a little bit of luck and a little bit of Bonine, the waves lull me to sleep each night so I wake feeling rested and I do not contend with nausea during the day. All in all, the best combination I could have hoped for.
And then there are the folks who need no meds at all and they feel fine. Lucky ducks.
Fifteen hundred years ago, a thousand years before Magellen’s crew successfully sailed around the world, sailors used otoliths to divine whether rough or fair seas awaited them on their journey. During the era of John Smith and Peter Stuyvesant, some Europeans recognized the otolith as medicinal with the ability to cure colic, kidney stones, and persistent fevers. If you’re truly interested in the legends associated with the otolith, you should read the brief and probably only account of Fish Otoliths and Folklore ever published. Though primarily informative, it reads with a touch of humor and it’s easy to tell that Christopher Duffin enjoyed researching the topic. As did I!
The science of otoliths as they’re used in the modern era is even more incredible than the folklore. You can determine the age of a fish by reading the annuli on its otolith under a microscope just as a botanist might count the rings on a tree to determine its age. The bands themselves can tell scientists how fast a fish grew and whether it went through periods of slower growth or not. The unique chemistry in each ring can also be studied to learn just about anything you’d want to know from that year – water temperature, migration patterns, what the fish ate, and how healthy it was. Since the shape of an otolith is unique to its species, we can even study the stomach contents and feces of other animals like sea lions or predatory fish to build a picture of their diets. Scientists use this information to craft complex food webs.
Anthropologists find otoliths in ancient scrap food piles called middens that are still intact and can shine light on the diets of bygone cultures. On this trip we’re saving fish for scientists at the San Diego Natural History Museum so they can compare bones from the coastal pelagic species with bones that they’ve excavated from archaeological expeditions.
But what is an otolith? Some call it an earstone. The otolith is a small structure of calcium carbonate that accumulates throughout a lifetime. Where humans have an ear canal, fish have an otic capsule that houses, actually, three symmetrical otoliths on each side of its head. When people say otolith though, they’re typically referring to the sagitta which is the largest one (in most fish) and is usually situated just behind the stem of the brain. Those are the ones we’re collecting during the Coastal Pelagic Species Survey. It takes such a concerted effort to collect them each night that one of the interns, Hilliard Hicks, started calling it the Otolympics!
To get to it is not pretty. The otoliths are situated within the brain cavity, posterior and ventral to the brain itself. The easiest way to get to them in a Jack Mackerel without breaking the otoliths is to first make a vertical incision where the base of the fish’s head meets its body. Then, turning the fish onto its side, you make another cut across the top of the fish’s head from one eye to the other. You’re essentially cutting off and removing a rectangular section at the top of the head to reveal the brain cavity. Then, after removing the brain, you get easy access to the otic capsule where the otoliths sit. Using small forceps or tweezers, we pull them out, dry them off, and encapsulate each fish’s sagittae in a vial for further study back on land. Multiply that process by about 75-100 and add weight and length measurements, and you get a sense of what our routine is after each trawl. We usually have 3-5 people attending to the task and it takes us roughly 45 minutes.
The main component of an otolith, calcium carbonate, is used today for lots of familiar medicines. While not derived from an otolith itself, it is still notable that calcium carbonate is a very common substance in pharmacology. We use it in antacids to neutralize the acid in our upset stomachs, to boost calcium thereby warding off osteoporosis, and to save us from enduring heartburn. It’s no wonder people used to pop otoliths in their mouth to cure what they identified as kidney stones. Maybe on some level, it really did help to assuage pain associated with their stomachs and digestion. In 2015, a team of scientists published a study in the Journal of Chemical and Pharmaceutical Research to share how they’ve been researching the use of otoliths with diabetes. There are far easier ways to collect stores of calcium carbonate, but the study shows that interest in otoliths stems not just to ichthyology, but also to climatology, anthropology, and pharmacology. It is an important little item.
Don’t have diabetes or an upset stomach? Not looking to see what the folks were eating in your neighborhood 500 years ago? Maybe you’d like to add an otolith to your wardrobe instead. In Alaska there are a couple of different places you could stop to purchase otoliths as jewelry. When used in earrings they look like tiny little feathers. A unique gift item for sure.
Stick with me for a minute while I get to my point. Earlier this week one of the scientists taught me about ctenophores (pronounced teen-a-fours with emphasis on the first syllable). They’re a type of zooplankton that look like translucent globes. If you’ve ever blown a bubble and watched it shimmer in the sunlight, that is exactly what they look like under a microscope. Except now visualize that bubble with eight longitudinal stripes lined with hundreds of little hairs. This orb is a living creature called a ctenophore.
Later, while I was reading on my own to research otoliths, I stumbled across the word ctenoids. A ctenoid scale on a fish has many little cilia (tiny hairs or spikes) all around its edge. “Cteno-“ can be traced back to Latin or Greek origins to mean “little comb” and I was able to use that understanding to help me visualize a ctenoid fish scale. So, here’s my point. If it weren’t for that short exchange with the scientist earlier this week about ctenophores, I would have breezed right past the word ctenoid while reading without ever having paused to visualize what the fish scale looked like. I would not have learned as much while I was researching on my own.
As teachers, we can’t possibly know all the things our students will come across in a day. By teaching them Latin and Greek word parts that align to our curriculum, they stand a better chance of connecting their lives outside the classroom to our class content.
Prefixes, suffixes, and root words are used in every discipline to help identify concepts and patterns. Don’t teach them in the abstract, instead teach them in word groupings so our students’ brains have something to latch onto. I particularly enjoy using root word tree images. Spending 15 minutes per week going over a root word tree with students, and providing them a digital link so they can look over it again at their leisure, is an excellent way to ignite a conversation in your discipline.
If I were a history teacher for example, I might choose to start a unit on modern democracy by passing out copies of the “dem: people” root word tree, telling each student to write a paragraph at the bottom of the page with whatever comes to mind while they’re looking at the tree. Then they could walk around the room sharing their writing with their classmates and highlighting patterns they find in the responses. They’ll hopefully never forget that a democracy is a government built of the people, by the people, and for the people (as the famous saying goes). At the very least, they’ll understand why the first three words of the preamble are “We the people…” and how a democracy is different from other forms of government like a monarchy, theocracy, and dictatorship.
Weather at 1000 Pacific Standard Time on Wednesday 17 July 2019
We’re expecting rougher weather at the end of the week. The wind is forecast to stay at 15 knots all day today with patchy fog. Then tomorrow and Friday winds double to 30 knots with waves of 12 feet. Currently the wind is 11 knots and the sea state is stable. The sunsets out on the water are spectacular! People gather on the fantail to watch the evening sun melt into the horizon when it’s exceptionally colorful or dramatic, and last night did not disappoint.
Most of the time during meals I sit with the science crew. Sometimes I’ll sit with my roommate, Lindsey, who works as an augmenter. Think of augmenters as floaters – they are employed full time but will move from one ship to another based on the needs of each ship. Lindsey helped me a lot this trip from learning how to do laundry and climbing in and out of a top bunk on a rolling ship (without falling) to understanding nautical terms. She’s also pretty good at spotting whales!
A couple of my meals have been spent talking with 2nd Cook Aceton “Ace” Burke. He normally is the Chief Cook on NOAA Ship Thomas Jefferson, but he’s augmenting on this trip to fill in for someone who is on vacation. When he’s cooking for his crew, his favorite meal to prepare is pork ribs. He cooks them low and slow for hours until they’re fall-off-the-bone tender.
He and Kathy keep the kitchen spotless, the food hot, and the mealtimes cheerful. Kathy was kind enough to share some recipes with me and I intend to take every one of them home to cook this summer! For dinner one night soon I’ll make Kalbi Ribs with Cheesy Scalloped Potatoes and Macadamia Nut Cookies for dessert. I’ll reserve the Creamy Chicken Rice Soup for a cold winter weekend and be sure to add chopped, roasted red peppers and wild rice to the recipe like Kathy instructed.
INTERVIEW WITH A CHEF
After working in an office environment for a few years in Los Angeles, our Chief Steward Kathy Brandts realized she didn’t fit the nine to five lifestyle. Plus, who would ever want to commute to work in LA? So she left LA and moved back to Colorado to live with her sister for a while until she found something more appealing.
That’s when cooking began to kindle in her blood. Every night she would sift through cookbooks and prepare dinner in search of a way to express gratitude to her sister for helping her get back on her feet. But it would still be a few years before she started earning a living in the kitchen.
First came the Coast Guard. At 27 years old, she was less than a year away from the cutoff. If she didn’t enter basic training before her 28th birthday, a career with the Coast Guard would no longer be an option. It appealed to her though, and a recruiter helped her work a little magic. She made the cut! While she initially wanted to work deck personnel so she could maintain the ship and qualify as law enforcement (some Coast Guard personnel, in addition to belonging to a military branch, can simultaneously take on the role of federal law enforcement officers), she was too pragmatic for that. It would have taken her three years to make it to that position whereas cooks were in high demand. If she entered as a cook, she wouldn’t have to wait at all.
So the Coast Guard is where she had her first taste of formal training as a cook. She traveled on a two year tour to places like Antarctica and the Arctic Ocean visiting port cities in Hawaii and Australia to resupply. Ironically, to be out to sea a little less often, she decided to join NOAA as a civilian federal employee after her service with the Coast Guard ended. She’s not exactly out to sea any less than she used to be, but now she gets to go on shorter trips and she can visit family and friends while NOAA Ship Reuben Lasker is in port between cruises.
Kathy is a perfect example of someone who wasn’t willing to settle for a job. She spent the first half of her life searching for a career, a calling, to energize and motivate not just herself but all the people her meals feed throughout the day. She believes that food is one of the biggest morale boosters when you’re on a ship, and it’s clear at mealtime that she’s correct. I watch each day as the officers and crew beam and chatter while they’re going through the buffet line. I hear them take time to thank her as they’re leaving to go back to work.
A well-cooked, scratch meal has the power to change someone’s day. Not only does Kathy take pride in her work as a professional, I also get a touch of “den mother tending to her cubs” when I see her interact with everyone on the ship. She says she provides healthy, flavorful meals because she loves food and wouldn’t want to serve anything she wouldn’t eat herself. In turn, this seems to make everyone feel cared for and comforted. When you’re packed like sardines in a confined area for a month at a time, I can’t think of any better morale booster than that.
I think it’s hard sometimes for students to visualize all the steps it takes to get to where they want to end up. As with all people, teenagers don’t always know where they want to end up, so connecting the dots becomes even less clear. Take Kathy as an example. She started her adult life in an office and ended up in a tiny kitchen out in the middle of the ocean. I doubt that at sixteen years old, sitting in some high school classroom, she ever would have imagined she’d end up there.
So our job as teachers is not to push students in one direction or the other. Part of our job, I believe, is to help students get out of their own way and imagine themselves in settings they won’t hear about in their counselor’s office. One way to do this is to invite people from our communities to come in and share how their profession connects to our curriculum. I can think of plenty of people to invite – the local candy maker, a trash collector, a professor researching octopods, a farmer, a cyber security professional or white hat, a prison guard, military personnel, an airline pilot, or a bosun (even though I probably won’t find any of those in my local community since I don’t live near the water). Reading about the profession is one thing. Talking to someone who lives it everyday is another.
One lesson I’m taking from my day spent in the kitchen is the value of scenario based activities. If student teams are posed with a problem, given a text set to help them form their own conclusions and plan for the solution, and then asked to present their solution to the class for feedback, that is a much more enriching lesson plan than direct instruction. In November my students will be tasked with preparing a budget and presenting a plan to feed 30 people for a three week cruise. I like the idea of the cruise because they can’t just run out to the store if they forget a few things – the plan has to be flawless. This one activity, though it would take a week to execute properly, would have my students making inferences and drawing conclusions from text, communicating with one another using academic language and jargon specific to the scenario, solving a real-world problem, and critically evaluating an assortment of potential solutions.
We can prepare students for “the career” regardless of what that ends up being. Every career requires critical thinking skills, problem solving, patience, a growth mindset, and the ability to communicate with others. And all these skills are essential to the classroom regardless of grade level or discipline.
Weather at 1300 Pacific Standard Time on Monday 15 July 2019
We’re slowly coasting through a dense patch of fog. I can see about 20 meters off the deck before the horizon tapers to a misty, smoky haze. Then my eyes are affronted with a thick wall of white. It’s like we’re inside a room covered in white felt wallpaper – one of those rooms in a funhouse where the walls keep closing in on you as you walk through it. For safety, the ship keeps sounding a loud horn at least once every 2 minutes to announce our position for other boats in the area. It’s been like this for an hour now. It’s a little spooky.
On a brighter note, we saw whales earlier this morning! We were one mile off the coast of southern Oregon, and ahead of us we saw the backs of a few whales peeking out of the surface. I was able to grab a pair of binoculars sitting next to me on the bridge, and with those I could clearly see their dark bodies in the water! Every once in a while one would gracefully lift its tail above the surface as it prepared to dive. They were so cute!
Eventually we got closer to them and we started to see more whales on either side of the ship. I spent probably 15 minutes moving from one side of the bridge to the other with my binoculars to get a better look. I’m lucky the NOAA Corps officers are so accommodating! Otherwise I think my constant fluttering from one area to another could’ve been construed as a pain.
The officers like to see whales too, so they were happy to share what they knew with me. It turns out we were most likely watching Humpback Whales. LT Dave Wang, Operations Officer on the ship and trained as an ichthyologist (fish biologist), said most whales have a distinctive blow pattern, tail shape, and dorsal fin size that makes it easier to identify which kind he’s looking at. I had no idea before today that there were so many different species of whales. I knew Orca – Free Willy, Humpback, and maybe something called a Blue Whale? But that would’ve been the extent of it. In the marine mammals identification guide housed on the ship, there are 45 types of whales in the table of contents! And that’s probably not a complete list of all whale species.
At one point today, eventually, once the fog lifted, we were 36 miles off shore and started seeing shoals of coastal pelagic species all around the ship. We could pick them out easily because each shoal looked like a dark, churning, rippled inkspot on the otherwise smooth-as-glass surface. While the low wind conditions are partly what left us in a thick layer of fog all afternoon, it is what also kept the water smooth enough to pick out the shoals. So I guess not all was lost. We saw even more whale activity around these shoals than we saw this morning, and they were a lot closer to the ship!
One of the whales just off the starboard bow left a footprint. Larger whales like the Humpback produce larger footprints, and the calm sea state today allowed us to see them! It looked like a smooth patch of water in the center of concentric circles.
I’ve been trying to see whales and other marine mammals the whole trip. I saw a sea lion the other day, just one glimpse of it before it went under the water and we left the area, but now having seen the whales I feel pretty content. The Commanding Officer of the ship also told me that seals or sea lions like to hang out on the pier that we’ll be docking at in San Francisco, so there’s still hope yet!
If you’ve ever been whale watching on a boat, the type of whale you probably saw was a Humpback Whale. They can often be seen near the shore since they like to stay within the continental shelf, and they spend a lot of time near the surface compared to other whales. Not all whale species exhibit this same behavior. If whales had a personality, I would call the Humpback Whales the Jersey Shore cast of the sea. They do things that come across as attention-seeking behaviors to the outside observer – slapping their unusually long flippers on the surface of the water, smacking their tails against the water in agitation, flipping their tails in the air before diving, and sometimes breaching the surface with their whole bodies. Of course, they’re not doing it to get our attention. But it makes for easy and exciting observation!
They also have the advantage of something called countershading. One of the whales I saw today had a silvery-shiny underside to its fluke that glistened in the sunlight and contrasted greatly with the dark, almost black color of its back. A lot of fish and marine mammals like whales and porpoises use countershading to help camouflage them by having naturally darker backs (dorsal side) and lighter stomachs (ventral side). This way when something is looking down at the creature, it blends in with the dark depths of the ocean, and when something is looking up at the creature, it blends in better with the lighter, sunlit layer of water near the surface.
Anything from krill to small fish are fair game for Humpback Whales when they’re hungry. Sometimes a group of Humpback Whales will work together as a team to catch fish. One way they do this is by bubble net feeding. It’s rare to witness, but a bubble net is a pretty sophisticated way to catch fish. It reminds me of the trawling we do each night from NOAA Ship Reuban Lasker except in this case the whales use a circular pattern of bubbles to corral a bunch of fish into one area… then they thrust forward aggressively, quickly, to scoop up the masses. We use a trawl net to corral the little critters into a codend instead of swallowing them whole.
Baleen whales, like the Humpback, have a unique mouth that is hard to explain. If you can visualize a pelican’s beak, it looks a bit like that from the outside. These whales gulp a whole mouthful of water – including zooplankton, krill, and small fish – into their mouths, but they don’t swallow it down outright and they don’t exactly chew their food either. With all that saltwater and prey in their mouths, they use long rows of baleen attached to their upper jaw like a fine-toothed comb. And just like we would use a cheesecloth to strain the moisture off of runny yogurt, Humpback Whales filter the water out of their mouths through the baleen and keep the fishy goodness for themselves.
Watching the whales all day kept drumming up images in my mind from when I read Grayson by Lynne Cox. I wrote a review of Grayson in July 2014 on the Pennsylvania Council of Teachers of English and Language Arts (PCTELA) blog. This book, by far, is one of my favorite recommendations to read aloud to students.
If you’re not an English teacher, you probably didn’t spend a lot of late nights in college reading novels to cram for a test. It wasn’t part of your major. But you’re missing out! There are so many ways to use novels and literary nonfiction across the content areas. Grayson, for example, is artfully written. In the book review I wrote it tells Lynne’s “account of meeting a baby whale in the ocean during one of her early morning training swims. This lonely whale, separated from its mother, stays close to Lynne in the water while fishermen search for the mother. This true yet almost unbelievable story is hauntingly beautiful.”
Taking 15 minutes of class time to read an excerpt from this book aloud could enrich any classroom. There are many instances when she writes about wanting to give up and swim back to shore. The baby whale is ultimately not her responsibility. It was very cold. She’d been out there in the ocean for hours with nothing but her own strength and experience to keep her afloat. She hadn’t eaten all day. But she stayed with the baby whale. She resolved to see it through to the very end. Any teacher can use her stick-with-it attitude as an example to encourage students to work through academic challenges.
One of my friends, blogger Allyn Bacchus, is a middle school social studies teacher. He uses historical fiction in his class every year. He writes, “My 8th grade U.S. History class covers a unit on Industry and Urban Growth in the late 1800’s and early 1900’s. I have supplemented our unit with the historical fiction novel Uprising written by Margaret Peterson Haddix. It covers the story of 3 teenage girls and their involvement in the Triangle Shirtwaist Factory in New York in 1911. The author brings to life the living, working, and social conditions of the time period and allows my students to experience this unit through the eyes of girls who are living in it.”
Through the eyes of girls who are living in it. This is something a textbook cannot do.
No one knows your discipline, your students, and your intended classroom environment better than you. Take an hour to fall down the Amazon rabbit hole! Search for a topic you find interesting and relevant to your curriculum, read the book review, click on the comparable book recommendations… you get the point. Most of the time you can find a book preview to check out the text before purchasing – is the font too small? Too complicated? Too boring? Choose a short excerpt from a text you like for your first attempt at using literature in the classroom and build from there.
Since we’re talking about literature today, I’ll narrate the resource list.
We can search online for other educators who have already blazed the trail for us. Here is a blog post written by Terry McGlynn titled Assigning Literature in a Science Class. The post itself is well written, and if you take the time to read through 54 comments below it, you will find lots of other text recommendations for a science classroom. This article written by Kara Newhouse titled How Reading Novels in Math Class Can Strengthen Student Engagement shows why two math teachers read books in their high school classrooms. One of those teachers, Joel Bezaire, wrote a blog post with suggestions for other novel studies in math class. The other teacher, Sam Shah, shares a student example to explain how powerful it can be to use literature in a math class. It gets students to understand abstract and often elusive mathematical concepts.
I’ve written four nonfiction book reviews to accompany this NOAA Teacher at Sea experience and PCTELA is posting one review each week in July to the new media platform on their website. If not Grayson, then maybe you’ll find useful one of the books I read and reviewed to prepare for this trip. They include Gone Tomorrow: The Hidden Life of Garbage, Blind Man’s Bluff: The Untold Story of American Submarine Espionage, The Hidden Life of Trees: What they Feel, How They Communicate – Discoveries from a Secret World, and Biomimicry: Innovation Inspired by Nature.
And finally, I would be remiss to end this post without steering you toward The Perfect Storm written by Sebastian Junger about a small fishing vessel and crew caught in an Atlantic storm and In the Heart of the Sea: The Tragedy of the Whaleship Essex by Nathaniel Philbrick – a captivating true story about the whaling industry which is thought to be the inspiration for Moby Dick.
Weather at 1600 Pacific Standard Time on Thursday 11 July 2019
Happy to report we’re back to a much calmer sea state! I finally made it up to the flying bridge again since it isn’t raining or choppy anymore. It’s the first time in two days I’ve needed to wear sunglasses. The ocean looks almost level with scattered patches of wavelets which indicates about a 5 knot wind speed. It reminds me of the surface of my palms after I’ve been in the water too long – mostly smooth but with lots of tiny wrinkles. Check out this awesome weather website to look at what the wind is doing in your area!
Stretch everyday. I should stretch everyday. I do not. On the ship it’s even more of a necessity. One of the scientists calls it “Boaga” – like mixing “boat” with “yoga.” Try doing yoga on the ship and the rocking might cause you to tumble, but I enjoy a good challenge. Fitness requires strength and flexibility, so if I do some yoga and have to work harder to stay balanced since the ship is rocking, all the better.
A combination of the good food, constant access to homemade snacks, and lack of natural ways to burn calories on the ship, I need to turn to deliberate exercise. I just haven’t started that routine yet. The ship does have a nice, albeit small, gym on the same floor as my stateroom. It includes free weights, kettlebells, a treadmill, and a few other pieces of equipment. Now that our first week is coming to a close, my goal for today – and everyday forward – is to develop a routine for stretching and cardio. Sigh. Otherwise the five pounds I’ve already gained will turn into fifteen. And I have no desire to work off fifteen pounds of belly fat when I get home.
“Trawl” has its origins in Latin. The original word meant “to drag” and it still carries a similar denotation. Fishermen use trawl as a noun, verb, and adjective. On NOAA Ship Reuben Lasker we use a Nordic 264 Surface Trawl to conduct the Coastal Pelagic Species Survey each night. The trawl is spooled onto a giant iron net reel which connects to the deck with sixteen 2.5 inch bolts and is securely welded. We try to get three trawls in per night, but sometimes we don’t quite make it. Poor weather, issues with the net, or sighting a marine mammal can all put a quick end to a trawl.
Now let’s use it as a verb. The origin “to drag” deals more with how you operate the net than the construction of the net itself. To trawl for fish like we do each night means to slowly unravel 185 meters in length of heavy ropes, chains, and nylon cord mesh into the water off the stern with an average of 15,000 pounds of tension while the ship steams at a steady rate of about 3 knots. Getting the net into the water takes about 15 minutes.
Scott Jones, Chief Bosun, took me on a tour of the equipment. Two reels below deck spooled with cable the diameter of my forearm, one even larger reel on the fantail to house the net and ropes, a winch to lift the weight of the trawl as it transitions from deck to water, plus two work stations for the Chief Bosun to manually monitor and control all those moving pieces. There are three additional nets on board in case they need to replace the one we’ve been using all week, but the deck crew are pretty adept at sewing and mending the nets as needed.
As I stand on the bridge watching the net snake its way into the water behind the ship, everything pauses for a brief moment so the deck crew can use daisy knots to sew floatable devices into the kites. Later, they attach two more of these floats to the headrope (top line). The floats keep the mouth of the net open vertically. A couple minutes later they stop to attach 250lb Tom weights to the footrope (bottom line) of the trawl opening. When fully deployed, this roughly 25 meter vertical opening is as tall as an 8-story building!
It’s like watching choreography – every detail must be done at exactly the right moment, in the right order, or it won’t work. The Chief Bosun is the conductor, the deck crew the artists. Hollow metal doors filled with buoyant wood core – together weighing more than a ton on land – are the last to enter the water. Each hangs on large gallows on the starboard and port side of the ship, just off stage, until they’re cued to perform. These doors are configured with heavy boots and angled in the water to act as a spreading mechanism to keep the net from collapsing in on itself.
If unspooled properly, the net ends up looking like an enormous largemouth bass lurking just under the surface.
Commercial fishermen use all kinds of nets, long lines, and pots depending on the type of catch they’re targeting, fishing regulations, and cultural traditions. But if we use “trawl” as an adjective, it describes a specific kind of net that is usually very large and designed to catch a lot of fish all at one time. It looks like a cone with a smaller, more narrow section at the very end to collect the fish.
I imagine something like a cake decorating bag that’s being used to fill a mini eclair. Except, instead of squeezing delicious icing into the pastry, we’re funneling a bunch of fish into what fishermen call a “codend.” This codend (pronounced cod-end, like the fish) houses the prize at the end of the trawl! When they haul everything back in – taking a little longer, about 45 minutes to complete the haul back – they end up with (hopefully) a codend full of fish to study.
A trawl net can either be used like we are to collect fish close to the surface or it can be weighted and dropped to the sea floor in search of groundfish. We’re searching for pelagic fishes that come up to the surface to feed at night, so it makes sense for us to trawl at the surface. Think of pelagic fish as the fishes in the water. Sounds funny to say, but these fishes don’t like to be near the seabed or too close to the land by the coast. They like to stay solidly in the water. Think of where anchovies, mackerel, tuna, and sharks like to hang out.
To catch groundfish on the other hand, we’d need to trawl the bottom of the ocean since they prefer to stay close to the ocean floor. Trawling the seabed in the Northeast Pacific Ocean would bring in flavorful rockfish and flounder, but we’re not looking for groundfish during this survey. One very lucrative and maybe less known groundfish in this area is the sablefish. In commercial fishing, they use bigger nets, and a trawl can bring in tens of thousands of pounds in just one tow. When I spoke to someone on board who used to work on a commercial trawl boat, he said catching sablefish are a pain! They live in very deep waters. Plus, the trawl must hit the seabed hard and drag along the bottom in order to catch them. This causes huge tears, many feet wide, in the mesh. He said they used to keep giant patches of mesh on the boat deck so they could patch up the holes in between trawls. When I get home, I’m definitely going to purchase sablefish and try it for dinner.
I’ve never once wondered how the fish I buy at the grocery store ends up on my plate. Now I can’t seem to stop asking the scientists and deck crew questions. There are all these regulations to follow, methods to learn based on what type of fish you’re targeting, and so much that someone would need to understand about traveling in the ocean before even attempting to fish commercially. I’ve been immersed in a world I don’t recognize, and yet the fishing industry impacts my life on a daily basis. We are so far removed from what we eat.
Like most teachers, I want my students to find a career that they love enough to practice with such diligence. I want them to find a vocation instead of just work to pay the bills. I feel very much led to making sure my students have access to as much information as possible about post-secondary career and training options. For that reason, I’m glad to have met these folks and learn from them so I can share their practice with the hundreds, possibly thousands of teenagers I’ll teach over the course of my career.
It’s easy for me to do this as a reading specialist since I can read career profiles with students, let them annotate the text, and then engage them in a discussion on a regular basis. Reading, analyzing, and discussing text are kind of my bread and butter. For other disciplines, it might take a bit of a re-work to fit this in, but certainly not impossible. A science, math, art, STEM, you-name-it teacher could post a career profile specific to their discipline to their digital classroom space each week for students to read at their leisure. Or you could bring discipline specific literacy skills into your classroom by incorporating short texts into your lessons a few times each quarter.
I’m planning now to read a career profile with my
students one time per week. I’ll keep the texts short so that reading,
annotating, and discussing the text will stay under 15 minutes. Some careers from the ship they might find
interesting are the Chief Bosun position or a NOAA
Corps Officer, but I’ll share a wide variety of career profiles from many
disciplines based on the students’ interests once I meet them this year.
Weather at 1100 Pacific Standard Time on Wednesday 10 July 2019
The winds picked up. Dreary is a good way to describe the sky – an overcast layer on top with smoky-gray smudges of smaller clouds just a little lower. According to the Beaufort Wind Scale, I can describe the sea as moderately choppy with 4’ – 8’ waves, white caps scattered throughout, and some spray. But on the scale that only accounts for 17-21 knots of wind. The instruments on the ship track the wind in real time, and it’s showing anywhere from 20 – 30 knots. Today I need a couple of light layers under a warm, cozy jacket to keep me feeling comfortable. And a hat to keep my hair in place while the wind blows all around us.
I didn’t want to get my hopes up in regard to food on the ship. Between the constant rocking, less than ideal conditions for fruits and vegetables, and confined space, I didn’t have high expectations. But once I got to NOAA Ship Reuben Lasker, the regulars on the ship thankfully put my worries at ease. They told me we have one of the best chefs on the NOAA fleet of ships.
Our Chief Steward, Kathy, is in charge of the kitchen. She makes her job look effortless, though I’m sure it’s not. She puts out an eclectic menu each day that would rival any popular restaurant. Since I’m a Food Network junky, I really think she belongs on Chopped. She’d blow her competitors out of the water! She seasons everything perfectly.
She always has snacks available like fresh baked macadamia nut cookies or homemade rice crispy treats. So far she’s served Peruvian chicken, kalbi ribs, chicken pad thai, open-faced meatloaf sandwiches, West African peanut soup, and chicken marsala. Oh, and pancakes, and omelets, and cheeseburgers, and Cuban sandwiches, and black bean soup, and… the list goes on. She always offers fresh fruit or a fresh salad bar. It’s clear she’s had a lot of experience working with the constraints this unique environment must put on her. I’m lucky to be on a ship with someone who so clearly loves to cook! The foodie in me is very happy.
The acoustics lab is something to behold. If you took a classroom and cut it in half lengthwise, it would be that large. Since we’re on a ship where space is limited, I get the sense that this equipment is important. And after working a shift in the room, I know why. The data collected in this room provides the backbone for the whole survey.
NOAA scientists use sonar to identify various types of fish in the water below us – and to the sides – as we travel along. Individual echoes from discreet targets – noise, small plankton, large fishes – show up on one screen as raw data. Through post processing, the system removes most of the unwanted echoes so that all we’re left with are echoes from the fishes of interest on a separate screen.
The Coastal Pelagic Species show up as a seemingly indistinguishable, colorful blob of dots on the screen, but our chief scientist Kevin Stierhoff interprets each blob with a fair amount of accuracy. He explained what looked like hocus pocus to me originally is really just simple logic. For example, pelagic species tend to stay relatively close to the surface. So if I see a blob of red and yellow that’s, let’s say, more than 100 meters below the surface, then I’m probably looking at a type of fish that prefers deeper waters near the rocky seabed. Those deeper blobs could indicate a species of Rockfish (of which there are plenty), but probably not one of the pelagic species we’re searching for.
Ever try searching for a needle in a haystack? Get frustrated and walk away? Yeah. NOAA is more strategic than that. Acoustic sampling is conducted during the day when the Coastal Pelagic Species are deeper in the water and schooled together. This makes them easier to see using the sonar equipment on board. Later we’ll return at night to noted areas of high activity to trawl for the anchovies, sardines, herring, mackerel, and squid while they’re closer to the surface feeding. Plus, they can’t see the net at night and therefore won’t be able to avoid it like they would if we attempted to trawl for fish during the day.
Acoustic sampling allows us to efficiently survey a much larger area than we could without it. Its primary purpose is to more precisely determine the biomass of the pelagic fish community over a large area. NOAA’s Southwest Fisheries Science Center started using this style of acoustic data collection to enhance its fisheries mission about 15 years ago, but this is only the second year they’ve deployed saildrones – wind and solar powered unmanned surface vehicles – to extend the survey area both in shore where it’s more shallow and far off shore where Reuben Lasker will not have time to travel during this survey. The saildrones allow scientists to capture more acoustic data from a wider survey area.
One of the coolest things about education is that we can connect students not just to their local community, but to their global community. For the last three years, the Pacific Marine Environmental Laboratory has written a blog to help classrooms and individuals follow the adventures of their latest saildrone missions. They’re intending to write another series of blog entries to track a mission in 2019 and 2020, but you could easily use one of the previous year’s text in the classroom if you can’t wait for the new entries to be posted. Read a few of these entries with your students and use them as a springboard to teach about cutting edge technology, stewardship, environmental science, storytelling, culture, math, or navigation.
Thankfully, almost any topic can be used to build literacy skills. When texts like this inspire me to connect my students to local and global community leaders in a particular field of interest, I usually reach out to the authors directly. Some teachers will find it more challenging to make these connections to their classrooms, but it is worth the effort. If I can find an email address or contact information for the person who wrote an article I enjoy, typically they can lead me to someone who is a dynamic speaker and willing to come into my classroom. Or sometimes they will offer to come out themselves if they live nearby. Then I find companion texts to read with my students before and after the person comes in to present.
The possibilities are almost too voluminous to count. In one direction, you could bring in a local scientist or graduate student doing interesting research to speak on some topic as it relates to your classroom content. You should also consider arranging a field site visit to a unique local gem if the funding is available. Usually local field trips are much less expensive. Our local communities are filled to the brim with places that relate to our class content. It takes a little leg work to find them sometimes, but if you choose the right place you’ll see a return on your investment for the full school year.
Last year I was lucky enough to coordinate a visit to the Penn Vet Working Dog Center in Philadelphia which is one of the leading working dog training facilities in the nation. It’s housed in a tiny little building off some obscure road in Philadelphia. I never would have found it if I weren’t out there directly searching for something like it. Most places like this can be found and initially filtered online with a little bit of strategic searching. Something as small as a one-day site visit or facility tour, if it’s the right location, can motivate students to push themselves academically a little bit further than they thought they could go on their own.
This one visit ended up being the springboard for my students to read authentic nonfiction texts (like media release forms and liability release forms), to think critically and make decisions, to write a press release, to build background knowledge, to enhance their vocabulary, and to learn the value of reading not for the sake of a grade but because interpreting the texts and being able to share information with others (like younger students they ended up mentoring or like our district’s administrative team who were interested in their project) was vital to the success of their project. Most important, it provided a means of intrinsic motivation for my students – that elusive creature that often comes so close to my grasp but then flutters away again when I use less engaging methods of classroom instruction.
If you want to go in more of a global direction, you could ask a facility farther away in another state or country if they have the capacity to involve your students in an integrated learning experience via Skype or old school pen-pal style communication throughout the year. Students can participate in or monitor on-going research around the world all while learning about unfamiliar cultures and locations. And of course, bring your own diverse experiences and travel into the classroom! Apply for the NOAA Teacher at Sea program to get out of your own comfort zone and be a positive means of bridging your classroom to the global community.
Weather at 1600 Pacific Standard Time on Monday 08 July 2019.
We’ve made our way back near the coast and we’re currently progressing south at a cautious 6 knots through a relatively shallow, protected area called Cape Perpetua Marine Reserve. The winds and sea are both calm. The deck is warm and sunny! The sky has just a few high level clouds that look like wisps of white painted onto a clear blue canvas. A long-sleeved cotton shirt is comfortable in this weather along with long pants and boots.

We left Yaquina Bay just after 1700 on Sunday evening. I was eating dinner when we left and had no idea we were moving. The ship is that smooth when it’s traveling slowly. I made it out just in time to see us pass the boundary between the bay and the Pacific Ocean. My job tonight is to stay up until 0200 so I can prepare for my 12 hour shift that starts Monday and runs from 1400-0200. We’ll see how that works out. I’m typically in bed long before 0200.
As the ship started making its way along the coast this evening, I sat on the Flying Bridge. The Bridge on a ship is often at one of the highest levels and it’s the command center. The Flying Bridge is one level above that. It is all open air with no windows and no walls (there are railings, of course). It was freeing and frightening at the same time! I think that’s my favorite area on the ship. I plan to go there a lot over the next few weeks to feel the sunshine, clear my head, and prepare for the day.
One of the scientists on board made a sensible comment yesterday. She said we should walk as much as we can before the ship sails because after that we won’t walk more than a few feet at a time in any given direction. Today I walked 7.5 miles all over Newport Marina. I’m tired, but I’m glad I heeded her advice!
07 July 2019
Today I learned more than I ever wanted to know about tsunamis. I went on an estuaries tour with the Hatfield Marine Science Center this morning and we saw a lot of “Tsunami Evacuation Route” signs along our tour. The tour guide explained a tsunami is actually a series of waves and not just one giant wave like we see in movies. Additionally, it doesn’t really “break” the way we’re used to seeing waves crash into the beach. Those waves are caused by the wind moving over the surface of the water. A tsunami reaches the coastline more like a storm surge or like a very strong tide because the energy forcing this wave forward comes from deep within the ocean floor – from seismic or volcanic activity – and not from the wind. Thankfully, in the ocean (where I’ll be for the next three weeks!) a tsunami is only barely noticeable with maybe a three foot height increase. But once the force of all that moving water hits the shallow bottom of our coastline, the water begins to pile up and can reach anywhere from a few feet all the way up to 100 feet above sea level.
The Newport Marina is in a Tsunami Hazard Zone. Most tsunamis tend to be less than ten feet high because energy from the point of origin must travel many miles before reaching a coastline, but the Newport Marina is in a particularly hazardous area because it lies within the Cascadia Subduction Zone. If a major earthquake hits this close to home, a larger than average tsunami could follow in just fifteen minutes! The Newport Marina is only six feet above sea level, so even a relatively small tsunami would cause intense damage from both flooding and debris.
A major earthquake shakes the Cascadia Subduction Zone once every 300-350 years on average. The last major earthquake in Newport, OR occurred in 1700, so… they’re due for another one soon. That might be why the Hatfield Marine Science Center decided to design its brand new building in Newport Marina to be both earthquake and tsunami resistant using state-of-the-art engineering methods. It includes a unique ramp on the outside of the building that spans multiple levels so people have easy access to the evacuation location on top of the roof. After seeing the current evacuation location, a very small hill just across the street from the marina, I think it’s good they’re adding a facility with capacity for another 900 people!
NOAA’s National Weather Service (NWS) provides a U.S. Tsunami Warning System. It works much like our system for tornadoes and thunderstorms by communicating four different levels – warnings, advisories, watches, or threats.

The man I met yesterday while he filleted his catch from Yaquina Bay is still sitting on my mind. He shared his story with me. When he was 18 years old, he was homeless. He had no connection to school because he didn’t fit into the square peg the narrow curriculum required. Pausing his rhythm with the fish, he tried to explain.
He’s dyslexic. When he was a kid, that threw him a gigantic curve ball. It took him a long time to learn how to adapt and overcome that challenge. What strikes me about his story is that school didn’t help him, it held him back. Dyslexia is one of the most common types of learning disabilities. Students are faced with challenges in school every day – whether it’s a learning disability or other challenge – and teachers are often there to support, teach, and guide students through those challenges. But I see students every year who, like this gentleman, don’t fit into the script. They’re the outliers who need a different approach.
Last year my district engaged in a study of Continuous School Improvement. While my understanding of it is still in its infancy, I do know that it requires us to look at multiple forms of data in order to get a wider picture of what is going on in our schools. We then use what we find to determine “where the fire is burning the hottest” (according to our Continuous School Improvement guru working with our district) and correct those issues first. Typically, by correcting those big ticket items, a trickle-down effect occurs that will solve some of the smaller issues organically.
I would definitely categorize the nature of this fisherman’s story as a big ticket item that many districts are trying to understand and correct. We all know that teacher in the building who connects with the students who don’t connect to school. There’s always that one teacher who manages to make this look easy – though it is not.
Even though reading comprehension, the primary means to learning in most disciplines, is difficult for the gentleman I spoke to at the filleting station, he valued learning so much that he stuck with it even as he failed his classes. He told me that he has thousands of audiobooks and a whole library of traditional books at home which he’s been accumulating for years. We talked about Malcolm Gladwell, tax preparation, real estate, and a host of other diverse topics. He runs his own successful business that he politely called “medium sized” as he smiled, sheepishly at his friend.
I hope, just as I’m sure all teachers hope, that my students who struggle each year will value learning enough to push through the challenges they each face. While I might not always succeed in teaching every student the content of my discipline, I at least hope that they each leave my classroom at the end of the year with a sense of desire to learn more. To not give up when the challenges pummel them, wave after wave, and feel unrelenting. I hope that someone will speak to them one day, 20 years from now, and they’ll wink as they describe how successful they’ve become due to their hard work, resilience, and unshakable love for learning. And that they’ll come to realize strong literacy skills are an integral part of learning.
Winds and sea are calm. Weather is cool. Heavy overcast layer of white, thick clouds in the sky. Very comfortable out on deck with a sweater or light jacket. The visibility is unreal – I can see for miles! Nothing but cold water and salty air.

Tomorrow I’ll board a ship with NOAA Officers and
scientists headed for a three week research cruise in the Pacific Ocean. My
whole life at home is not skipping a beat without me. But I feel like I’ve hit
a pause button on my character. Like I won’t return to the movie of my life
until the end of July. Important decisions get made without me. Disputes with
family and friends won’t include my voice again for almost a month. Everything
moves forward at home this summer but me.
I have a new appreciation for folks who dedicate their lives to careers requiring them to be away from home for long periods of time. This is only three weeks. I can’t imagine the way I would feel if I were leaving for three months. Or a year. I do feel very grateful for the opportunity to spend the next three weeks with these people though. They will be, no doubt, passionate about their careers, and I’ll learn a lot from traveling with them.
06 July 2019
After a 6 hour flight from the East Coast to the West Coast and a 2.5 hour car ride from Portland International Airport to Newport, Oregon, I’m finally on NOAA Ship Reuben Lasker! A handful of scientists, two volunteers, and myself met at the airport. We coordinated so all our flights would arrive within an hour of each other so we could drive together. As soon as we got there, my roommate gave me a tour of the ship. It didn’t take very long, but there are a lot of ways to get lost! I felt a little disoriented after that. There is a galley and dining area which they call the mess. I’ve been told we have one of the best chefs on board our ship! A laundry room, exercise room, plenty of deck space, the bridge where NOAA Officers will navigate and operate the ship, and stairs. So. Many. Stairs.
Upon meeting the chief scientist, Kevin Stierhoff, it became clear that the Coastal Pelagic Species Survey is a big deal. NOAA runs this survey every year for about 80 days! They break it up into four 20 day legs. Most of the scientists will rotate through only one or two legs, but the NOAA Corps Officers in charge of the ship’s operation typically stay for the full survey. That’s a very long time to be away from home.
We’re traveling on the 2nd leg, so the survey has already been underway since June. It started farther north off the coast of Vancouver Island, British Columbia and will meander down the coast for almost three months until it reaches the US-Mexico border. Kevin described the ship’s movements like someone explaining how to mow the lawn – we will run perpendicular to the coast in a back-and-forth pattern traveling south, slowly, until we get to the waters off San Francisco Bay. First we’ll travel straight out into the ocean, turn south for a bit, then travel straight back toward the coast. Repeat. Repeat… for three weeks.
Why such a funky pattern, you might ask? We’ll be using acoustic sampling during the day to determine where the most densely populated areas of fish are located. Then at night, we’ll put that data to good use, immediate use, as we trawl the waters for specific types of pelagic species. There are five species in particular that the scientists want to study – anchovy, herring, sardines, mackerel, and squid – because they’re managed species or ecologically important as prey for other species. That funky pattern of travel allows us to sample the whole coastal region.
It reminds of me of one of the scanning patterns the Civil Air Patrol uses when we conduct search and rescue missions from a Cessna. When I was trained to be a scanner in the back seat of the plane, they taught me to look for signs of a missing person or downed plane below me in a systematic way. If I just look sporadically at everything that pops into my line of scan, I’ll never find anything. It’s too haphazard. But if I start from a fixed point on the aircraft and scan out up to a mile, then bring my scan line back in toward the plane, I’ll naturally scan all the ground below me for clues as the plane moves forward.
Even though they’re looking primarily at those five coastal pelagic species, the scientists will catalogue every kind of fish or marine life they find in their trawl nets. They are meticulous. It’s such an important endeavor because it helps us to fish our waters using sustainable practices. If this survey finds that one of the fish species in question is not thriving, that the population sample of that species is too low, then NOAA Fisheries and the Pacific Fisheries Management Council will set harvest guidelines next year to help that species rebound. If it’s looking very dire, they might even determine that commercial fishing of that species needs to be put on pause for a while.
Since the three hour time change traveling in this direction worked in my favor, I gained three extra hours of daylight to explore Newport. I spent most of the evening walking around the small port where NOAA docked Reuben Lasker. It’s only a couple square miles, but it houses the Oregon Coast Aquarium, the Hatfield Marine Science Center’s Visitor Center, Rogue Brewer’s on the Bay, and a public fishing pier. I walked a total of 6 miles today and was never bored.
The fishing culture struck me the most. Kids, adults, everyone seemed to have a working knowledge of local sustainability, ecosystems, commercial fishery practices, things that are so foreign to me. I suppose it would be like going to Pennsylvania and asking someone to explain deer hunting. Trust me, we can. But fishing? Not as much. I wish that we as teachers would tap into the local knowledge base more fully. From Pennsylvania for example, we could share Amish culture and heritage, details about the coal mining industry, steel production and engineering practices, hunting, and so much more. Until I realized how unaware I was of the local knowledge here in Newport, I never stopped to think about how rich and diverse my students’ local knowledge must be as well. One thing I plan to do this school year is dig into that local culture and explore it with my students.
I watched one gentleman as he filleted his catch at the filleting station just off the pier. To me it looked like a cooler of fish. I could tell you with certainty that they were indeed fish. But he knew each type, why the Lingcod had blue flesh instead of white, how many of each type he was allowed to take home with him, how to cook them, and the list goes on. I was impressed. In talking with others this evening, it seems like that’s par for the course here. Later, a couple of fishermen with a cooler full of crab started talking to me and offered me some to try. It was cleaned, cooked already, fresh out of Yaquina Bay. It was delicious – sweet and salty.
The people I interacted with today, every single one of them, were genuinely kind. They were patient and explained things to me when I didn’t understand. This is a lesson every teacher can take to the classroom. We know how important it is to smile and be kind. We know it. But sometimes it’s hard to put that into practice when we’re rounding into May and having to explain that one tricky concept again, pulling a different approach out of our magic hat, and hoping that this time it will click.
It’s not always easy to mask the frustration we feel when something that is so natural for us (in no doubt because we love the subject and have studied it for at least a decade) just doesn’t make sense to a student. And it’s not always the student I get frustrated with, it’s myself. Teachers tend to be their own worst critics. When a lesson doesn’t go as well as we expected, we double down and try harder the next day. No wonder so many of us burn out in the first five years and switch to a different career!
Oregon Coast STEM Hub – STEM lessons for many disciplines including language arts, ocean science, and math
June 2, 2019 Game Plan and Trawling Line: 5 hauls in the Piedras Blancas Line near San Simeon, CA. Piedras Blancas is known for its Northern elephant seal colony, M. angustirostris. Hauls were conducted outside of the marine reserve and we did not encounter seals.
Catch Highlights: The night started off with excitement when Keith Sakuma brought in an Pacific electric ray, Torpedo californica, and we all got to see it up close before releasing.
In Haul 3 we collected a pelagic octopus, Ocythoe tuberculata, shown below. Chromatophores in cephalapods, including squid, cuttlefish and octopus, are complex organs made up of both muscle and nerve and provide the ability for the animal to rapidly change its skin color in order to blend into the surrounding environment to avoid predation, communicate, or send a warning signal. It was impressive to watch the chromatophores at work as the pelagic octopus attempted to blend into the white background of his tank by turning white (see photos below) We released it back to the sea.
The differences in skin coloration of the five primary squid species we are catching including Boreal Squid, Blacktip Squid, Unknown Squid, Gonadus Squid, and Market Squid (see image below) are noteworthy. While living market squid exhibit brown, pink and purple skin color (see image below) the Chiroteuthis squid tentacle displays orange and red chromatophores (see image below).
In Haul 4 we collected a Cranchia scabra, which Chief Scientist Keith Sakuma calls the “baseball squid” or glass squid whose body is covered with tubercles (brown spots on mantle in photo below). This animal attempted to hide from us by turning white, retracting its tentacles and inflating himself into a ball, somewhat resembling a baseball. After a few pictures, we released it back to the sea.
Another exciting deep-sea creature, the Pacific hatchet fish, Argyropelecus affinis, was collected in a bongo net deployed prior to CTD, for Dr. Kelly Goodwin’s eDNA research. The fish we collected below still has intact blue scales due to being well preserved in the bongo. The hatchet fish lives in mesopelagic zone down to 2000 m depths where the CTD sensors recorded a temperature of four degrees Celsius! Hatchet fish have upward facing eyes and mouths and swim up to the the epi-pelagic zone at night to feed on salps and krill.
Kelly conducted a quick surface bucket dip prior to CTD deployment in which we found a small (~2 inch) siphonophore, which I was very excited about since this was my first one to ever see in person! Siphonophores are colonial Cnidarians composed of individual animals called zooids. Moss Landing Graduate Student Kristin Saksa and I were able to confirm the identification of this beautiful creature as a siphonophore using an invertebrate field guide that Keith Sakuma brought on board. Perhaps due to the temperature change from being in the sea to being observed in a cell culture dish under the microscope, the siphonophore broke apart into its individual zooids right in front of my eyes. See before and after photos below.
Tonight I was also able to observe living salps that were pulled up in the bongo net and take a video. It was neat to see the salps pulsing.
Haul 5 was a massive haul full of pyrosomes, Pyrosoma atlanticum. Kristin Saksa volunteered to stir the bucket of pyrosomes (using her arms) so that we could obtain an accurate distribution of organisms for the initial volume count and analysis. As I video of this event (see stills from the video below), we were all laughing and realized that Kristin may be the only human on Earth who has ever stirred pyrosomes.
In haul 5 we were surprised to find a Giant 7-armed Atlantic octopus, or blob octopus. Keith Sakuma explained that the males have 7 arms as the fifth is a sex appendage whereas the female has 8 arms. After photographing this beautiful deep-sea octopus, we released him back to the sea.
June 3, 2019 Game Plan and Trawling Line: 5 hauls Outside Monterey Bay
Catch Highlights: Two of the hauls produced a lot of krill. The hauls had a high species density with a lot of myctophids, salps and blue lanternfish. Such hauls are time consuming to sort so as not to overlook something new and small. In one of the hauls we found a new-to-me myctophid called Nanobrachium. I dissected some of the fish and found that CA lanternfish and Northern anchovies were full of eggs, and their age/reproductive status was previously unknown.
We caught 2 young ocean sunfish, Mola mola. Both were immediately returned to the sea.
We found several species of deep sea dragonfish which we arrayed below on a ruler. Most of these fish are less than 6 inches long, no bigger than a pencil, but they are equipped with sharp fangs and are apex predators in their realm! Dragonfish have large bioluminescent photophore organs underneath their eyes (and sometimes lining their bodies) which produce light and are used to attract or deter prey and attract mates.
We collected a stoplight loosejaw, Malacosteus niger, which can unhinge its jaw in order to consume large prey.
June 4th: Davenport Line
The highlight of today was at 5:45 P.M. when team red hats went to the flying bridge for our workout and to hang out with Ornithologist Brian Hoover. There was a lot of Humpback whale activity. I counted around 20 spouts. We observed one whale that flapped its tail against the sea surface around 45 times in a row, perhaps communicating to nearby whales by generating pulses in the water or creating a visual cue. We saw several full breaches. We finished up the Davenport Line at 6:00 AM as the sea became rough. Thanks goodness for handrails in the shower.
June 5th: Outside of Tomales Bay
I woke up at 4PM and headed to the galley for dinner at 5PM. The boat was rocking so much that I became dizzy and knew that I would become sick if I tried to eat dinner, so I headed straight back to bed. Around 9PM the sea seemed to have calmed a bit, but I soon learned that it only felt calmer because the ship was traveling in the same direction as the swell at the moment but that we were about to turn around. Due to the rough conditions, the first haul inshore at Tomales Bay was delayed until midnight so the fish sorting team decided to watch “Mary Poppins Returns” in the galley. The talented chefs of the Reuben Lasker made the most amazing almond cookies today and, thankfully, temped me to eat again.
Catch Highlights: Haul 1 at station 165 was one of the easiest and most exciting catches of the survey so far because we collected a lot of jellyfish – my favorite! We counted 66 West Coast sea nettles, Chrysora fuscescens, seven Northern anchovies (7) and 24 market squid. I actually have a tattoo of West Coast sea nettle on my ankle. We placed the jellyfish flat on the lab bench and quickly measured their bell diameter before returning them to the sea. They did not sting us as most of the nematocysts were likely triggered during haul in. I removed a rhopalia, a sensory structure that lines the margin of the bell of Syphozoans (the “true” jellyfish). West Coast sea nettles have eight rhopalium which house the the ocelli (light sensing organ) and statolith (gravity sensing organ). A photomicrograph I took of the rhopalia under the dissecting microscope is below.
Haul 2 mostly consisted of Northern anchovies, 1 krill, a few moon jellyfish, Aurelia aurita, a few squid, which made for another very short and easy sort (see photo below). I study moon jellyfish in my lab back at McCallie High School, so I was curious to look inside of the stomach and reproductive organs of these wild jellyfish. Under the dissecting microscope, eggs were present and were purple in color (see photomicrograph below).
Haul 3 had a lot of krill, young of year (YOY) Pacific hake, Merluccius productus, one large hake, and a few market squid. This sort was also super easy except for separating the small YOY Pacific hake from the krill.
June 6th: Outside Farallones. On our final night, we conducted three hauls with very small harvests consisting of few organisms and low species density. One new to me fish in the final catch was a top smelt fish (see image below). These were the three easiest sorts of the survey. It was suggested by Keith Sakuma that the catches were small due to the stormy conditions.
Scientist Spotlight: Flora Cordoleani, Ph.D., NOAA NMFS, SWFSC, Fisheries Ecology Division (FED). Dr. Cordoleani is a member of the fish sorting team on this survey.
Interests: Rock climbing, surfing, reading, studying Japanese
Education: Dr. Cordoleani’s doctoral degree is in Marine Biology and Ecology from Aix-Marseille University in France. There she researched interactions between phytoplankton and zooplankton. During her postdoc at the University of California, Davis, in the lab of Louis Botsford, she studied the impact of marine protected areas on rockfish along the CA coast.
Current Research: Dr. Cordoleani leads a research program at UC Davis on preservation of Chinook Salmon, Oncorhynchus tshawytscha, of the Central California Valley Spring Run, which is a threatened species. She explains that these Chinook Salmon are genetically different from salmon of other runs such as the Late Fall, Fall, and Winter runs that take place in the Sacramento River, San Joaquin River, the Delta, the San Francisco Bay, and all of its tributaries.
The primary objective of Dr. Cordoleani’s research is to develop a life cycle model of the entire Spring Run from the spot where the young salmon are reared in the river to their journey through the Golden Gate to the sea where they spend a couple of years before returning back to their home river to spawn, thus completing the life cycle. She aims to uncover environmental factors that are impacting the survival at each stage of the life cycle.
Project 1: Dr. Cordoleani’s team placed acoustic tags in the stomachs of young fish to trace their journey from the river to the ocean. She has found that water temperature, water velocity, and flow are the major factors impacting whether or not juvenile fish are able to make it from their place of birth to the Golden Gate. She has observed that drought negatively impacts survival and that the fish fare better in wetter years. Her data helps federal agencies, such as NOAA, with fish stock assessments and informs them for making science policy decisions on fishing and setting fishing quotas.
Project 2: Since water flow and velocity affect the survival of young salmon called fry, Dr. Cordoleani is very interested in water usage in the Central California Valley and gaining a better understanding how freshwater habitats are managed and how this affects wild salmon. A major obstacle these fish encounter are dams, which blocks the natural flow of rivers. Spring run salmon have an additional challenge of low water levels and low stream flow in the Spring. During the Spring months, there is less water available in floodplain habitats due to the heavy consumption of water by the agriculture industry during this time.
To study the effects of water flow and velocity on salmon fry, Dr. Cordoleani made mesh fish cages and placed the cages in either shallow floodplain habitats or the main river. She placed ten fry (measuring 40 mm in length) in each cage and allowed them to grow for 6 weeks. At the end of the 6 weeks, she again measured the fish and found that the floodplain shallow water habitat promoted fish growth.
Rice farmers use floodplain habitats for their crop and Dr. Cordoleani is working on partnering with this industry to explore how they can work together to manage land to benefit native salmon runs. She is excited that the rice farmers, as well as duck clubs, are interested to learn how their land can be used to help wild salmon populations thrive and how they can be a part of the solution to some of the obstacles wild salmon face.
Project 3: Fish otoliths provide a treasure trove of information to reconstruct the life history of fish. The CA Department of Fish and Game has for many years been collecting otoliths from salmon carcasses after spawning events throughout various locations in the Central CA Valley. They gave Dr. Cordoleani access to their 450 stored otoliths for her research on the salmon life cycle. She will analyze the otoliths using laser ablation mass spectrometry and stable isotope analysis (using the Strontium 64 or 65 ratio) to determine in which river the adult fish were reared, where they were present at each stage of their life cycle, and how long they spent there. She will also be able to determine if the fish were wild or farmed-raised because hatchery feeding produces a different strontium signal, she explains.
With data from the otolith project, Dr. Cordoleani will compare different cohorts of fish and assess how fast the fish grew in each type of habitat in order to understand which habitats are most ideal for salmon survival. Importantly, she will be able to determine whether and how their growth was affected by different environmental factors and seasons over the years. Dr. Cordoleani uses USGS databases and other agency websites to obtain water data records for her research.

Time Recap: 5:00 PM: Wake up and then Squat Challenge. 5:30 PM: Dinner. 8:30 PM: Report to fish lab. Learn how to count to ten in French. Kristin sang France’s National Anthem (she learned in 7th grade). 10 PM: First Haul. 3AM: Kaila used her face flip app to turn us into the opposite sex and it was the most hilarious thing ever. 4AM: Latte made by Kaila. A lot of laughing. 6:20 AM: Finish fish lab clean up. 6:21 AM: Still heavily caffeinated so Team Red Hats headed up to the flying dock to watch the sunrise. The sea was very smooth and glassy as we approached Conception Point. We saw several dolphins and a humpback whale. 7:00 AM: To the Galley for a breakfast of blueberry pancakes. 7:45 AM: Lights out.
Part 1: How to distinguish between myctophid species in our catches
In this survey, we are conducting trawls at 30 meters, which is technically the epipelagic zone, so why do we catch deep sea creatures? Many deep sea creatures, such as myctophids, participate in a daily vertical migration where they swim up into the upper layer of the ocean at night, likely following the migration of zooplankton on which they feed. Myctophids are also known as lantern fish or lampfish and they feature photophore organs which bioluminesce. Around 250 species of mcytophids have been described. Graduate student Ily Iglesias is saving a lot of the myctophidae we catch on this cruise for her dissertation work.
Tonight most of the catches were small in volume (filling about 10% of a blue bucket), but had good species density. The catches consisted mostly of salps, anchovies and several species of myctophids. It is important to learn how to properly distinguish between the various myctophids in our catches. This is a daunting task for the novice fish sorter, such as myself, since these fish are small (1 to 2 inches long) and appear very similar to each other. It is worth noting that most of the myctophids lose their skin (scales) during the trawling operation. This exposes the underlying pink muscle tissue, however, their photophores remain intact. Fish collected in a bongo net deployment typically have better preserved scales.
Northern lampfish, Stenobrachius leucopsarus, have 3 photophores in a slanted line under the lateral line while the similar looking Mexican lampfish, Triphoturus mexicanus, have more streamlined bodies and have 3 photophores on the lateral line. Many of the Northern lumpfish had a heart parasite which is evident in the photo below. California lanternfish, Symbiophorus californiensis, are typically larger fish and have a distinguished lateral line. California headlight fish, Diaphus theta, have two photophores “headlights” on the front on their face. Blue lanternfish, Tartetonbeania crenularis, are easy to distinguish from the others because they have wider bodies and blue/silver scales.
Part 2: Rockfish: why are we catching so few?
Last night there were 4 rockfish in the last haul, and the fish sorting team got excited because we have not seen very many. The title of this survey is officially “Juvenile Rockfish Recruitment and Ecosystem Assessment Survey,” however, sampling for pelagic juvenile rockfish is only one of the project’s objectives. Other objectives include sampling for other epi-pelagic micronekton species, studying prevailing ocean conditions and examining prominent hydrographic features, mapping the distribution and abundance of krill (Euphausiacea), and observing seabird and marine mammal distribution and abundance.
Rockfish, perch, or redfish are common names for the Sebastes genus of fish (with more than 100 species) which are abundant off of the California coast, and are a very important genus for the commercial fishing industry. Rockfish are benthic fish that live among rocks, and can be found in kelp forests or in the bathypelagic zone. One of the goals of this survey is to inform the fishing industry on the status of the population of rockfish so that reasonable catch limits can be set.
This year is proving to be a poor year for the rockfish pre-recruitment index, lower than the previous several years, says Chief Scientist, Keith Sakuma. He explains that one year of a weak young of year (YOY) rockfish class is not enough to have an impact on the fishing industry, but if the index was low for say, 10 years in a row, then this could potentially affect the exploitable population. He explains that since rockfish can live to be 100 years old or greater, they have many seasons to reproduce. Rockfish prefer cold water habitats. Keith’s research has demonstrated that most poor pre-recruitment index years are correlated to El Nino events which cause an increase in water temperatures and a reduction in cold water upwelling. This year’s slump in terms of rockfish numbers is not correlated to a strong El Nino event.
Part 3: Environmental DNA (eDNA) Sampling on the Reuben Lasker
Last night Flora Cordoleani and I helped Dr. Kelly Goodwin collect water from the Conductivity, Temperature and Depth (CTD) bottles for the purpose of collecting environmental DNA (eDNA). Kelly’s assistant, Lauren Valentino, is primarily on the day shift (see photo of Lauren with the CTD apparatus below). Isolation of eDNA from seawater is a newer technique used to determine which species swam through a particular location based on the DNA they left behind, through shedding of cells. This technique does not require that the organism be harvested to know that it had been present, and could be of value in detection of the presence of endangered species, for example.
For this CTD deployment, three bottles are filled at depths of 5 and 100 meters, and at the chlorophyll max somewhere between 5 – 20 meters. The water from each depth is run through a filter (pore size of 2 microns) in the eDNA lab on the ship (see photo below). The vacuum filtration procedure is a time-consuming process, as samples must be processed in triplicate, and in which aseptic technique is paramount so that human DNA does not contaminate the water. Once the DNA is trapped on the filters, they are stored at -20C. The DNA will be purified from the filters back in the San Diego NOAA lab using a Qiagen kit. Species-specific regions of DNA known as bar-code regions will be amplified by Polymerase chain reaction (PCR) using 3 primers sets for analysis of DNA from bacteria, plankton, and fish. Illumina techology will be used to obtain DNA sequences, which are compared to DNA libraries for species determination.
The results from the eDNA study will give us a list of species that were present at each trawling station up to 48 hours prior to CTD deployment and fishing using the Cobb Trawl. We will be able to compare this list with the list of species that were physically caught in nets. Nighttime CTDs are deployed at the same station as bongo nets. Daytime CTD trawls occur at the same stations as night fishing.
Part 4: Career Spotlight: NOAA Commissioned Officer Corps, Scientist Interview: Keith Hanson, NOAA Lab Operation Officer B.S. Marine Biology, University of Miami (UM) Hometown: Rye, New York
Keith Hanson joins this survey to assist with research and is a knowledgeable and experienced member of the science team. Keith has taught me a lot about the fish we are collecting and was the first to show me around the ship.
Keith earned a Bachelor’s degree in Marine Biology from the University of Miami (UM) where he was vice president of the scuba club. His favorite part of being a student at UM was being located so close to ocean and the many trips he took to Biscayne Beach and The Everglades. While at UM, Keith worked as a Naturalist at the Biscayne Nature Center and with the Marine Operations Department at The Rosenstiel School of Marine and Atmospheric Science (RSMAS), where he managed boats and vehicles.
After graduating from UM, Keith started the NOAA Corps Basic Officer Training Class (BOTC) at the U.S. Coast Guard Academy in New London, Connecticut. His first assignment as a Junior Officer was on the NOAA Ship Nancy Foster in Charleston, SC which has a multi-mission platform with fish habitat and population studies, seafloor mapping surveys, oceanographic studies, and maritime heritage survey. Keith enjoys the traveling opportunities afforded in this line of work. On the Nancy Foster, he got to travel to Cuba, the Caribbean, and Mexico. After 2.5 years of service, Keith advanced to OP Officer.
Keith is currently on his land assignment in Santa Cruz NOAA working as the Vessel Operations Coordinator and he manages a fleet of small boats from kayaks to a 28 foot barge. Most vessels are used for river salmon work and groundfish research. His favorite vessel is the Egret offshore fishing boat which is used for rockfish hook and line sampling.
When asked what advice he has for undergraduate students wanting to purse degrees and careers in marine biology, he suggests getting involved in a research lab early on to gain a competitive edge.
Game Plan and Trawling Line: Channel Islands San Nicolas Line
I am up on the flying bridge and I just saw two humpback whales spouting, an albatross soaring and a large Mola Mola on the sea surface. In this blog I will write about an amazing once in a lifetime experience that from last night- May 31, 2019. The first haul was called off due to an abundance of Pacific White-Sided Dolphins, Lagenorhynchus obliquidens, (as reported by the inside marine mammal watch prior to net deployment), so we motored on ahead to the second station, but dolphins chased the ship all the way there, too. One strategy to encourage marine mammals to leave is for the ship to stop moving with the hope that the dolphins become disinterested and vacate the area. This pod was intent on having a party at the ship so Keith Sakuma encouraged everyone to just go outside to observe and enjoy the dolphins!
Fishing on this survey takes place at nighttime (so the fish do not see the net) and Scripps graduate student Kaila Pearson and I stepped outside on the side deck into the darkest of dark nights. Kaila and I carefully placed one foot in front of the other because we couldn’t see our feet and where to step next. I was afraid I would trip. When I asked Keith Hanson if we should use a flashlight to safely make our way up to the top deck, he suggested that we stay in place for a few minutes to allow our eyes to adjust. Within 5 minutes or so objects around us started to present themselves to us within the black void. We could eventually see our feet, each others faces, the dolphins, and even the finer features of the sea surface.
Within a few minutes Ily Iglesias reported seeing bioluminescence, a type of chemiluminescence that occurs in living things, such as the familiar green glow of lightening bugs in the Summer in the South. This glow results from oxidation of the protein luciferin (present in photophore cells/organs) by the enzyme luciferase. It its excited state, lucifern emits light. This reaction is known to occur in some marine bacteria, dinoflagellates (single celled photosynthetic organisms), squid, deep sea fish, pyrosomes and jellyfish, and I am fortunate to have observed many of these creatures already on this research cruise (see photos below). Some animals have photophore organs and generate their own luciferin, while others are hosts to bioluminescent bacteria.
When dinoflagellates floating on the sea surface are agitated, they glow. At first when I was trying really hard to see this, I noticed a couple of tiny flashes of green light, sort of like lightening bugs, but it wasn’t anything super obvious. In time, I noticed clouds of faint light, sort of like a glowing mist floating the water’s surface, that moved up and down with the swell. I hypothesized that dinoflagellates on the sea surface were being agitated by the passage of waves through them and Ily suggested that it was caused by schools of anchovies.
Since the dolphins were intent on staying, we decided to head to the next station. I knew that as the ship began to move that the bow would be breaking through surface water that had previously been undisturbed, and I predicted the bioluminescence would be much more intense.
As we took off, the dolphins began to bow surf and, as I predicted, the dinoflagellates were activated and this time their glow was a bright white. As the dolphins surfaced to breath, their skin became coated with the glowing algal cells, creating an effect as if they were swimming in an X-ray machine. The dolphins were literally glowing white swimming in a black sea! We were so entranced and excited by the beauty, we screamed in delight. I am sure the dolphins heard us cheering for them. They too, seemed excited and could see each other glowing as well.
Next we saw the faint cloud of dinoflagellates caused by Northern anchovies (Ily was right) up ahead of us. As the ship encountered the school of small (~ 3-6 inch) fish, they also started to glow really bright and it was easy to see all of the individual fish in the school. The dolphins could also see the glowing fish and split off in different directions to hunt them. There were hundreds of fish that dispersed as they were being chased creating a pattern of short white glowing lines somewhat like the yellow lane markers on the highway.
The display was unlike anything I have ever witnessed. It was like the Aurora Borealis of the sea. Despite our best efforts, our cell phone cameras were unable to pick up the bioluminescent signal, however, we do not need photos because the patterns of light will be forever embedded in our minds. The dolphins eventually tired from the surf and chase and departed. Ily said the experience was “an explosion of light that overwhelmed the senses” while Flora said it was “better than fireworks.”
With no marine mammal sightings at the third station, we completed a five minute haul in the deep channel and collected a huge white bin of anchovies (see photo of Keith Hanson with this catch below). In this catch we found a few Mexican lampfish, 3 king of the salmon, a lot of of large smooth tongues, a lot of salps, a few pyrosomes and one purple striped jellyfish. The purple-striped jelly (Chrysaora colorata) is is primarily preyed upon by Leatherback turtles. Haul 2 was conducted over shallower water near San Nicolas Island and we only found salps and four small rockfish in the catch. After these two hauls, we called it a night and wrapped up at 4:15 a.m.
Scientist Spotlight: Ilysa Iglesias, NMFS SWFSC FED/ University of California Santa Cruz (UCSC)
Ilysa “Ily” is a doctoral student who works in John Field’s Lab at UCSC. She is studying the fish we are collecting on this cruise as part of her research. She is very knowledgeable about all of the survey research objectives. She is also one of the most positive and gregarious people I have every met. Ily grew up in Santa Cruz, CA, and enjoys surfing, hiking, gardening and raising chickens. Ily is a fan of early marine explorer Jacques Cousteau, who often wore a red beanie/toboggan and a blue shirt. Ily came prepared and brought six red hats (that she knit herself) for each of the members of the sorting team. Ily’s favorite fish is the hatchetfish. She was thrilled when we found on in the catch!
Ily obtained a Bachelor’s degree from UC Berkeley in integrated biology and a Masters Degree from the University of Hawaii in Zoology with a specialization in marine biology. Her thesis was on the function of intertidal pools as a nursery habitat for near-shore reef fish. She compared otoliths (fish bone ears) of fish reared inside and outside of tide pools and compared their growth rates. Otoliths can be used to the age of the fish much like counting rings on a tree and stable isotope analysis reveals information about where the fish were reared.
Ily, Flora and Kristin have all used otoliths in their research and taught me how to locate and collect the sagittal otolith from anchovies and myctophids. It is a tiny ear bone (one of three) that is positioned near the hindbrain of fish. See photos below of the otoliths we collected. This is a technique that I will definitely take back to my classroom and teach my McCallie students.
After obtaining her masters degree, Ily was Conservation Fellow for the Nature Conservancy in HI and worked in octopus fisheries before returning home to join NOAA’s salmon team and then the rockfish team as a Research Associate. Ily has just completed the first year of her doctoral work in the Field Lab and expects to complete the program within 5 years.
On this cruise, Ily is collecting small fish called Myctophids for her research. These are small bioluminescent fish that live at depths of 300 and 1,500 m in the bathypelagic zone. In this survey, we encounter these deep sea dwellers during their nightly vertical migration up to the edge of the photic zone at depths we are targeting. They are likely chasing their prey (krill) on this upward journey. It is amazing to me they are able to withstand the pressure change. Mcytophids are also known as lanternfishes and have bioluminescent photophores dispersed on their bodies. The fish sorting team analyzes the position of these organs to help distinguish between the different species. There are 243 known species of myctophids, making these little fishes one of the most diverse vertebrates on Earth. They are so abundant in the sea that they make up 65% of the ocean’s biomass, but most people have never heard of them!
In 2014- 2015 there was an anonymously high sea surface temperatures off of the Pacific Coast known as The Blob. Marine scientists are still elucidating the effect of the hot water had on fish populations and ecosystems. Ily explains that “atmospheric forcing caused changes in oxygen and temperature resulting in variability in the California current.” The water was less nutrient dense and caused a reduction in phytoplankton. This disruption of primary production propagated up the trophic cascade resulting in die offs of zooplankton, fish, marine mammals and birds.
Ily is using the catch records and acoustics data from the rockfish survey to study changes in distribution and abundance of myctophids from before, during and after The Blob (2013-2019). She aims to understand if and how their trophic position of myctophids was affected by the unusually high sea surface temperatures. Using elemental analysis isotope ratio mass spectrometry to analyze the Carbon and Nitrogen atoms incorporated into fish muscle, Ily can determine what the myctophids were eating each year.
I’m actually afraid of the sea. The unspeakable power, the dark depths, the mysterious uncharted territory – the sea has always held curious minds captive. I want to be someone who faces the things that scare me. And for 19 days, on a relatively tiny ship, I will be doing just that.
NOAA Ship Reuben Lasker is “one of the most technologically advanced fisheries vessels in the world” according to the Office of Marine & Aviation Operations. In addition to studying fish and marine life populations, it is also equipped for acoustic data sampling and the gathering of oceanographic data. It can stay out to sea for up to 40 days at a time without needing to return for food or fuel replenishment.
And yet, as I’m writing this, I can’t help but think about SS Edmund Fitzgerald and RMS Titanic. They were the most advanced ships of their time too. Of course, I’m just letting my imagination get carried away. People fear the things they don’t understand. And I’m looking forward to learning as much as I can on this cruise in order to understand not just how this incredible vessel operates, but also how the ocean and atmosphere impact my life on a daily basis.
I was lucky last year to stumble across a professional development opportunity funded through the American Meteorological Society. I took two graduate level courses since then – DataStreme Atmosphere and DataStreme Ocean. Upon finishing this program I’ll earn a graduate certificate from the California University of Pennsylvania and be able to apply my new understanding of earth science directly to my classroom instruction. Already I’ve been able to incorporate fascinating information about coral reefs, the Bermuda Triangle, map reading, and weather into lessons and activities this year.
Why does a Reading Specialist need all this professional development, you might ask? In science of all things? Because nobody reads about things they’re not interested in (unless they have to). Students need to have something to connect with, to care about, in order to learn. When was the last time I, as an adult, read something I didn’t care about? Probably years.
Humans are curious by nature, and by incorporating new topics into our reading lessons over the past year, I’ve noticed that students really like learning about earth science. It’s like the mother who hides cauliflower in the lasagna – students are more motivated to read when they’re reading about something exciting and directly relevant to their lives. Thankfully, the more they read, the better they get at comprehending the nuances of the text. And then the less they need me.
One of the most valuable aspects of this trip for me is that I’ll return with a new appreciation for earth science, current events as they relate to our food supply and environment, and marine life. I can use this experience to build exciting lessons for high school students who may use their connection to these lessons as a lifeline. The last ditch effort to find something exciting to learn before graduating with a lackluster memory of the doldrums of the high school classroom.
Teenagers are tough eggs to crack! But I like them. And I’m very grateful to the NOAA Teacher at Sea program for giving me, and other teachers, opportunities like this to show our students that there are literally thousands of directions to take after high school in regard to career and quality of life. And that high school is one of the few places where they can build the foundational knowledge necessary to get them there – for free. I want my students to pursue their passions. To get excited about learning! And the first step to doing that successfully is to expose them to as many post-secondary options and lessons about their world as we can in the short time that we spend with them. Thanks NOAA! I’m excited to start my journey.
Last night I fell asleep, twice, at the lab bench in between trawls, since I am still adjusting to being on the night shift. We worked from 9:00 P.M. to 6:30 A.M. After the shift I had a nice hot shower and slept a solid 9 hours from 7:00 AM to 4:00 PM. Hopefully, I will be less drowsy tonight!
Upon waking, I went to the galley and grabbed some Raisin Bran and coffee and took it up to the flying bridge to hang out with Ornithologist Brian Hoover. Our current location is in the middle of the Channel Islands, an area I know something about because my friend Evan Morrison, mentioned in my first blog, helps with the Channel Islands Swimming Association, and I would like to swim between these islands one day. Lauren Valentino, Flora Cordoleani, Ily Iglesias and I congregated on the flying bridge and decided we should exercise. We joined Flora in her squat challenge (80 squats on this particular day), followed by 5 minutes of planking and a bit of erging. Half of female members of the fish sorting team are avid rock climbers. They did lots of pull-ups using the rock ring climbing training holds that are installed there.
It felt nice and warm when the ship stopped for deployment of the Conductivity, Temperature and Depth (CTD) Rosette, and it got chilly again as the wind picked up when the ship started moving again. We saw a few whale spouts in the distance and at 5:30 P.M. we went down to the galley for a delicious meal of steak and mashed potatoes. I am beginning to really appreciate how nice this whole experience has been in terms of amenities. The NOAA Reuben Lasker first set launch in 2014 and is a state of the art fisheries vessel with a sophisticated acoustics lab, fish lab, dynamic positioning system, CTD, etc., but is ALSO equipped with creature comforts including a movie lounge, an ice cream cooler loaded with ice cream sandwiches, snickers, fruit pops, you name it, and my personal favorite – a coffee bar where all coffee is freshly ground, an espresso machine, and all varieties of milk and creamers, including Reese’s cup whipped cream. The mattress in my stateroom bunk is quite comfortable and the shower gets hot within seconds! I doubt it can get much better than this for a research experience at sea?
Game Plan and Trawling Line: Point Sal line with five 15 minute hauls.
I am familiar with the sorting protocol now. The catch is dropped from the net into the bucket by members of the deck crew and survey tech, with the oversight of Keith Sakuma, Chief Scientist and NOAA Operations Officer Keith Hanson. The bucket is immediately placed in the fish lab and this is when the fish sorting team starts our work.
SORTING AND COUNTINGMETHOD
We start by carefully picking through a 2000 mL or 5000 mL volume of the harvest, depending on Keith Sakuma’s initial assessment of the species density and volume in the bucket. The first volume of catch to be sorted is evenly dispersed onto four white sorting trays arrayed on the main lab bench. Once you have a pile of the catch on your tray, you start to separate them into piles of different types of organisms, such as Northern anchovies, ctenophores, krill, salps, pyrosomes, Californian smoothtongues, squid, rockfish, myctophids, and young of year (YOY) fish. I prefer to use my hands for sorting while others use forceps. Once sorted, we count the number of individuals for each species. If we have difficulty identifying an animal that we have not yet seen, we ask Keith Sakuma or a more experienced team member to help with identification. YOY fish, some in larval form, are particularly difficult for me.
Once sorted and counted, we verbally call out the common name and number of organisms to Keith Sakuma who manually records the data in a 3-ring binder for the lab hard-copy. For smaller organisms, such as krill or salps, or in hauls with a high number of any particular species, it would be quite tedious to pick out and count each individual in the total haul. This is why we start with a small subsample volume or 0.5, 2 or 5L, count the individuals in that small volume, establish the ratio for the number of individuals in that volume, and then extrapolate and calculate by the total volume of the haul. For example, if we counted 97 pyrosomes in the initial 5L sort, and we collected a total of 1000L, then we can say that there are 19,400 pyrosomes in the haul.
Once 20 individuals of each species have been called out, we no longer have to count that species since the ratio for this catch has already been established and to expedite sorting the rest of the volume. Following sorting, the length of the twenty representatives of each species is measured using electronic calipers and the values populate on an Excel spreadsheet. After measuring, specimens requested by various research institutes including Scripps Institution of Oceanography, Moss Landing, and Monterey Bay Aquarium Research Institute (MBARI) are collected, labelled and frozen.
Creature(s) feature: Salps and Pyrosomes.
Salps What are these strange gelatinous organisms in our catch that look like little puddles of clear jelly with a red, green, yellow, and brown digestive organ in the center? They are goopy, small and slippery making them difficult to pick up by hand. They float on the sea surface and are ubiquitous in our hauls BUT NOBODY KNOWS ABOUT THEM.
These creatures are called salps and belong to the subphylum Tunicata. Tunicates have a notochord in their early stage of life which makes them members of the phylum Chordata, to which humans also belong. Having a transparent body is a way escape being preyed upon.
Salps are planktonic tunicates That can be found as individual salps or in long chains called blastozooids. The salps shown in the photo below were individuals and were notable in most of our hauls. Individual salps in this pile are dime to quarter sized and occupy a volume of ~10-15 ml. We measured the volume of salps in every haul.
While on the topic of salps, I will tell you about a cool 1 inch long salp parasite I found on my sorting tray (see image below). Keith Sakuma explained that it was a deep sea amphipod called Phronima which is a parasitoid that takes up residence inside of a salp’s body, eats the salp’s organs, and then lays its eggs inside of the salp. The King-of-the-salmon, Trachipterus altivelis, (which we are also catching) uses its protrusible jaw to get inside of the salp just to eat this amphipod!
Another type of salp we keep catching is Thetys vagina, a large solitary species of nektonic salp that feeds on plankton, such as diatoms, and is an important carbon sink in the ocean. Thetys has an external surface, or test, that is covered with bumps and ridges, as seen in the photo below.
PyrosomesPyrosoma atlanticum are another type of planktonic tunicate which are very numerous in most of our hauls. Pyrosomes look like bumpy pink hollow tubes with openings on both ends. They are rigid in structure and easy to pick up by hand, whereas salps are goopy and difficult to pick up by hand. We have collected some pyrosomes that are 13 inches long, while most are in the 4-6 inch range. The small pyrosomes look like clear Tic Tacs, but they do not taste as such.
How can pyrosomes be so ubiquitous just 20 miles or so off of the Central California Coast, but I have never seen one that has floated up on the beach or while swimming?
Pyrosoma atlanticum are also planktonic tunicates, but are colonial organisms made up of many zooids held together by a gelatinous structure called the tunic. One end of the tube is wide open and filters the water for zooplankton and phytoplankton, while the other end is tighter and resembles a diaphragm or sphincter. The pyrosomes we harvested appeared in diverse array of pinks and purples. Pyrosomes are believed to harbor intracellular bioluminescent bacteria. Pyrosomes are drifting organisms that swim by beating cilia lining the branchial basket to propel the animals through the water and create a current for filter feeding.
I departed Chattanooga, TN, for San Francisco, CA, on May 28th to participate as a NOAA Teacher at Sea on Leg 2 of NOAA’s Juvenile Rockfish Recruitment and Ecosystem Assessment Survey. My job as a Teacher at Sea will be to share my experience and knowledge acquired over the next 10 days working alongside NOAA scientists with MY AUDIENCE. Who is my audience? You! I hope that you all can be my students! You, my McCallie students and colleagues, my friends, my swimming community and my family members. My intention here is to explain in layman’s terms what I learned, and especially, what I thought was cool.
After tapas in North Beach with my San Francisco friends Cathy Delneo and Evan Morrison, they dropped me off at Pier 15 to sleep in my stateroom on the NOAA Ship Reuben Lasker. I felt rocking even while docked in the San Francisco Bay, but I slept great and am happy to report that my CVS brand “less drowsy” Dramamine tablets seem to be working as I am prone to motion sickness. This morning Evan and I got to explore the ship and take a bunch of photos of The City from the top deck of the ship, called the Flying Bridge. I imagine I will be spending many hours up here over the next 10 days!
Meeting the Science Team
The first science team member I met was Kelly Goodwin, Ph.D., an environmental molecular biologist from NOAA National Marine Fisheries Service (NMFS), Southwest Fisheries Science Center (SWFSC) La Jolla, and NOAA Atlantic Oceanographic and Meteorological Laboratory. Kelly is here along with Associate Researcher Lauren Valentino to collect environmental DNA (eDNA) from water collected at three depths (5 meters, the chlorophyll maximum, and 100 meters) during deployment of the Conductivity, Temperature and Depth (CTD) Rosette. There will be more about these marine scientists and the cool biotechnology they will be employing to come in a future post!
Next, I met my stateroom bunkmate Flora Cordoleani, Ph.D., of NOAA NMFS, SWFSC,Fisheries Ecology Division (FED). Her research lab at the University of California Davis focuses on the management of the endangered king salmon in the Central California Valley. I will definitely interview her for a future blog!
Meet the rest of the team: Doctoral student Ilysa (Ily) Iglesias, NMFS SWFSC FED/ University of California Santa Cruz (UCSC), works in John Field’s Lab. Ily will be analyzing the myctophids (one of the most abundant mesopelagic fish groups) collected on this survey and elucidating their role in the trophic cascade. She was on the cruise last year as well and I can already tell is psyched about this opportunity and wants to teach everyone.
John Field, Ph.D., was on the previous leg of the cruise and is the Principal Investigator for this project while Keith Sakuma, of NMFS SWFSC FED, is the Chief Scientist and has been working on this survey for 30 years as of this cruise!
Kristin Saksa of NMFS SWFSC FED/ Moss Landing Marine Lab (MLML) and Kaila Pearson, NMFS SWFSC FED, of Scripps, who are both working on master’s degrees in marine science.
Jarrod Santora, Ph.D., an ecologist from NMFS SWFSC FED/UCSC, will be on the day shift. Brian Hoover, Ph.D., an ornithologist who works for the Farallon Institute for Advanced Ecosystem Research (FIAER), will be observing birds and marine mammals on the day shift.
Keith Hanson is a NOAA Corps Officer representing NMFS SWFSC FED and is also a valuable member of the science team.
After a welcome aboard orientation and safety briefing given by NOAA Corps Officer David Wang, we enjoyed a delicious reuben sandwich in the galley (cafeteria) of the Reuben Lasker. Meals are served at 7 AM, 11 AM and 5 PM. Since I will be on night shift I can request to have meals put aside for me to eat whenever I want. Below is a typical menu. The food is superb! See a menu from one of our last days below.
After a noon departure the engineers spent a couple of hours testing the dynamic positioning system just north of the Bay Bridge. This system takes inputs from ocean conditions such as the tide, wind, waves and swell and uses the propulsion and thrusting instruments on board to maintain a fixed position on the global positioning system (GPS). Most of the night shift science crew used this opportunity to nap since we had to stay up all night!
Kaila Pearson woke me up just in time as we exited San Francisco Bay to take in the spectacular view of passing under the Golden Gate Bridge. It was a gorgeous sunny day in San Francisco and I felt super grateful to be a part of this research team, excited to get to know the team of amazing (mostly) female scientists I had just met, and ready to start fishing! It was fun to get to serve as a impromptu San Francisco tour guide as we departed the Bay, since I am quite familiar with this landscape. This body of water was my first open water swimming playground when I used to live in San Francisco during my postdoc at UCSF and was a member of the South End Rowing Club.
Night 1 of Cobb Trawl and Fish Sorting
We arrived at our first trawl line, Monterey Bay, around 11:00 P.M. My job as part of the night crew is to participate in marine mammal watches before and during fishing, and then to sort, count and measure the different species of animals collected, as well as bag and freeze specimens for various research organizations. The fishing method used on this survey is a modified Cobb midwater trawl. The net is deployed to fish at 30 meters depth and has a 9.5 mm codend liner (mesh at the end of the net where the fish gather). Trawl operations commence just after dusk and conclude just before dawn, with the goal of conducting up to 5 trawls per night. The duration of fishing at target depth before “haul back” of the net can be either 5 minutes or 15 minutes. Five minute trawls are used in areas of high abundance of gelatinous organisms such as jellyfish in order to reduce the size of the catch (e.g., fishing the additional 10 minutes would result in catches large enough to damage the net).
There are two marine mammal watches per trawl: the inside watch and the outside watch. The inside watch goes to starboard side of the bridge 30 minutes prior to reaching the planned trawl station. If any marine mammals such as sea lions, seals, dolphins or whales are spotted within one nautical mile of the planned trawl station, then the ship must move. This protocol is employed for mitigating interaction with protected marine species.
If the inside watch does not see any marine mammals, then trawl operations can begin. This is when the outside mammal watch takes over and looks for marine mammals during net deployment, trawling, and haul in. The outside watch is conducted one floor above the fishing deck, and the person must wear foul weather gear, a life vest, and a helmet. This is summer, but it is the Pacific, and it is COLD out there. If a marine mammal is spotted by the outside watch then the trawl net must immediately be reeled in.
I spotted a school of dolphins in Monterey Bay during haul back and reported the sighting via radio to the bridge officers and recorded my observations in the lab on the provided data sheet in the lab.
The duration of the entire fishing operation from net deployment, dropping the two “doors” (large metal plates weighing 900 pounds each) used to spread the net mouth open, fishing, haul in, properly wrapping the net on the winch, and finally, dispensing the harvested fish into the collection buckets, takes between 45 minutes to an hour and a half, depending on conditions.
Our first catch consisted primarily of Northern anchovies (Engraulis mordax) and California market squid, Doryteuthis (Loligo) opalescens. Ily was excited by the presence of a few plainfin midshipman, Porichthys notatus, and showed us their beautiful pattern of large photophores located on their ventral surface. These fish are quite hardy and survive the trawling procedure, so as soon as we saw one in the bucket, we placed it in a bowl of sea water for release after obtaining its length. Photophores are glandular organs that appear on deep sea or mesopelagic fish and are used for attracting prey or for confusing and distracting predators.
Mesopelagic depths start around 200 meters, a depth at where 99% of the sunlight can no longer penetrate, and extend down to 1000 meters below the ocean surface. Above the mesopelagic zone is the epipelagic zone where sunlight reaches from the ocean surface down to 200 meters and, in California, corresponds to the ocean above the continental shelf.
In this survey, we will conduct trawls at 30 meters, which is technically the epipelagic zone, so why do we catch deep sea creatures? Many deep sea creatures participate in a daily vertical migration where they swim up into the upper layer of the ocean at night as that area is relatively rich in phytoplanktonic organisms. Phytoplankton are the sun-powered primary producers of the food chain, single-celled photosynthetic organisms, which also provide the majority of the oxygen we breath.
After the first night of work I feel confident that I can identify around 10 species of mesopelagic fish and forage organisms, the California Headlight Fish (more to come on these amazing myctophids from my interview with Ily), a juvenile East Pacific red octopus, Octopus rubescens, (alive), and ctenophores! Thanks to the Tennessee Aquarium’s Sharyl Crossly and Thom Demas, I get to culture ctenophores in my classroom.
Scientist Spotlight: Ornithologist Brian Hoover
Brian Hoover, Ph.D., an ornithologist who works for the Farallon Institute for Advanced Ecosystem Research (FIAER) in Petaluma, CA, observes birds and marine mammals on the day shift of this NOAA research cruise.
Brian is from Colorado and earned his doctorate
at UC Davis in 2018. On this cruise we will be traversing through
biological hotspots that occur near islands, underwater canyons, and where
there is strong upwelling of the cold and nutrient rich deeper waters of the
California Current. Small fish feed on these nutrient rich waters, and
birds feed on these fish. Hotspots on this cruise included the Gulf of the
Farallons (just south of the Point Reyes upwelling plume) , the Channel Islands,
and Monterey Bay with its submarine canyon. Brian’s hours on the ship are from
7am to 7pm.
Brian can be found perched on the flying bridge during the day shirt with a pair of binoculars in his hand and his laptop off to his right on a table. Every time a bird or marine mammal is spotted within 300 yards of the ship to the right of the mid centerline of the bow, Brian records the species and numbers of animals observed in his database on his laptop. The objective of Brian’s work aboard the ship is to study how what is present underwater correlates with birds observed above the water. In other words, he aims to find correlations between the distribution and abundance of seabirds and marine mammals to the species and abundance of prey we collect during our night trawls and data collected from the ship’s acoustic krill surveys which collect data during the day. Brian explains that such information teaches us about what is going on with the bird’s prey base and how well the ecosystem is functioning as a whole. His observations allow him to observe shifts in the system over time and how this affects tertiary and apex predators. To find trends in these datasets, he used R software, Python, and ArcGIS mapping software to run spatial statistics and linear models.
Since 2010 Brian has been on 12 to 13 cruises and this is his third on the Reuben Lasker. Brian is excited to perhaps spot the Cooks Petrel, Pterodroma cookii, or the Short-tailed albatross, Phoebastria albatrus, which only lives in a volcano in japan. His favorite birds are the storm petrels because these birds are small and live in open ocean, only coming onshore to breed once a year. His dissertation focus was on the reproduction and behavior of the leeches storm petrol. He explains that seabirds have an incredible sense of smell which they utilize to find a mate and food. Brian was able to collect blood samples from burrowing birds for genotyping. He found that the major histocompatibility complex (MHC) molecules located on antigen-presenting cells may play a role in odor detection and mate selection in these birds. He found that males chose and avoided particular genotypes combinations and that healthier birds had more diverse MHCII complexes.
Brian is a sensory ecologist and studies how
seabirds interact with their environment through observations of their
behavior and physiology. When Ily asked Brian how do the seabirds know where
the fish are in the open ocean, he explained that birds have a sense of smell
that is as good or better than any commercial sensor that detects sulfur.
Why have some seabirds evolved to be so good at sniffing out traces of sulfur
in the ocean breeze up to 10 miles away from its source? Brian explained that
sulfur is an important part of the photosynthetic pathway for phytoplankton
(algal cells) and that when krill eat the algae, the algae releases the
chemical dimethyl sulfide (DMS). Marine plastic debris floating on the
sea surface also release DMS and provides an explanation as to why seabirds eat
Hi! My name is Karah Nazor and I am a science teacher at McCallie High School, an all-boys college preparatory school in Chattanooga, TN, which is also my hometown. It is one week until I board the Reuben Lasker in San Francisco, and I am already dreaming about fish. I teach marine biology, molecular biology and environmental science and “coach” students in our after-school science research program. We typically have around 20 tanks running at a time in my classroom including three species of jellyfish, a reef tank, zebrafish tanks, and a freshwater shrimp tank. Ongoing marine research projects in my lab include primary culture of nerve nets of the jellyfish Aurelia aurita, moon jellyfish,(students Jude Raia and Danny Rifai), the effects of ocean acidification on the jellyfish Cassiopea xamachana, upside down jellyfish,(students Ian Brunetz and Shrayen Daniel) and spawning of the lobate ctenophore Mnemiopsis leidyi (Thatcher Walldorf). Seniors Keith Kim and Eric Suh just presented their findings on the effects of river acidification on freshwater snails at the International Science and Engineering Fair in Phoenix, AZ, and sophomore Kevin Ward just wrapped up his research on the effects of a high sugar diet on tumor formation in tp53 zebrafish.
I am a lifelong competitive swimmer who loves the sea, marine mammals, and birds, and like many of my students today, as a high schooler I dreamed of becoming a marine biologist. I earned a bachelors of science in biology with a minor in gerontology from James Madison University, where I was also on the swim team. I was interested in learning more about the neurodegenerative diseases of aging, such as Alzheimer’s disease (AD), and attended the Ph.D. Program in Gerontology at the University of Kentucky and worked in the Telling Lab. There I studied the molecular foundation of prion diseases, caused by protein misfolding which forms aggregates in the brain, a pathology similar to AD. I continued this research as a postdoc at the University of San Francisco (Prusiner Lab).
How did I come to raise jellyfish in my classroom?
Chattanooga is home to the world’s largest freshwater aquarium, the Tennessee Aquarium, located on the Tennessee River waterfront. This non-profit public aquarium has two buildings, River Journey, which opened in 1992, and Ocean Journey, which opened in 2005. The Ocean Journey exhibit “Boneless Beauties and Jellies: Living Art” (2005-2019) featured exotic invertebrates including around 10 species of jellyfish, ctenophores, cuttlefish, giant Pacific octopuses, and spider crabs. On my first visit to Ocean Journey in 2005, I became transfixed with the “comb jelly” (the ctenophore Mnemiopsis leidyi) tank, specifically its rapidly beating ctene rows, which refract light creating a rainbow effect, and function as the animal’s swimming organ. Many people mistake the light refraction of the beating ctenes for electrical signals traveling along the ctenophore’s body. This first visit to the comb jellies tank left a lasting impression on me, and I was truly inspired by their beauty and curious to learn more about this gelatinous creature..
Six years ago, I visited the comb jelly exhibit again and decided to try to bring jellyfish into my classroom. I missed swimming in the frigid waters of the San Francisco Bay, so I sought to bring the cold ocean and at least one of it’s critters into my classroom. I chose to raise the Pacific Ocean variety moon jellyfish, which I so often encountered swimming in the San Francisco Bay and at Tomales Point! A gifted student built a special jellyfish tank, called a Kriesel, and next I contacted the TN Aquarium’s invertebrate specialist Sharyl Crossley to inquire about how to raise jellyfish. I was beyond thrilled when she invited me to train under her for a summer! That Fall, I began culturing moon and upside down jellies in my classroom and my students began research projects right away. Raising jellyfish is not easy, as they require perfect current, and water the salinity and temperature that matches their native habitat. Jellyfish require daily live feed of two day old enriched brine shrimp nauplii and rotifers. We actually have to feed the jellyfish’s food. The next year, I was ready to introduce the more difficult to raise comb jellies into the lab and have cultured them ever since. In 2017, I got to spend a week with Dr. William Brown at the University of Miami to learn how to spawn ctenophores, study hatchlings, and dissect out stem cell rich niches from the animals for in vitro work in the cell culture lab. You can often find me in the lab late at night at the dissecting scope still mesmerized and awed by the simplistic nature and immense beauty and of ctenophores in their spawning bowl.
Back to the Bay Area for a cruise on NOAA Ship Reuben Lasker!
The years that I lived in San Francisco for my postdoc were some of the best of my life because of the science plus athletic opportunities afforded by living next to the ocean including open water swimming, surfing, and abalone diving. I made lifelong friends partaking in these cold and rough water ocean sports. I lived in the Sunset neighborhood and I often went to Ocean Beach for the sunset and swam in the Bay several times per week at the South End Rowing Club (SERC). In 2008 I swam the English Channel. While swimming in the Bay, we often saw NOAA ships and I never thought I would get to join a cruise one day as part of the science team! While living in San Francisco, I did have the opportunity to go on a couple of whale watching tours and swim all over the San Francisco, Richardson, and San Pablo bays for my training swims, but I have never got to spend much time on a boat and I have never spent the night at sea! I am a bit nervous about becoming seasick and adjusting to being on the night shift next week.
Even though I was raised visiting the Atlantic ocean for summer vacations and am fond of the Caribbean Islands and the coral reefs, I am partial to the West Coast, where the mountains meet the sea. I prefer the cold green rough seas, the winter swell, kelp forests, abalone at Fort Bragg, great white sharks at the Farallones, Pier 39 sea lions, harbor seals, salps, humpbacks, orcas and sea otters in Monterey Bay, Garibaldi of La Jolla Cove, sting rays of La Jolla Shores, and elephant seals of Ano Nuevo. I enjoy kayak fishing for rockfish and yellowtail in San Diego with my brother, Kit.
The rockfish recruitment survey is a longitudinal research project in its 30th year led by the NOAA chief scientist Keith Sakuma. I have always been inspired by ichthyologists, specifically Dr. David Etnier, of the University of Tennessee, who worked with my step-dad, Hank Hill, on the snail darter case (Hill v. TVA) in the court’s first interpretation of the Endangered Species Act in 1978. I am excited to learn from NOAA chief Scientist Keith Sakuma and the other members of the Reuben Lasker‘s science team about the rockfish and groundfish species we will be targeting in the recruitment survey. I look forward to learning how to identify up to 100 additional species of epipelagic fish, most of which I have never seen (or even heard of) before, as well as micronekton including several types of krill, tunicates, and hopefully jellyfish!
The animals we will be surveying are known as forage species and are mostly primary and secondary consumers in the food web. These young of year rockfish and groundfish, epipelagic crabs, and small fish such as anchovies, sardines, and lanternfish are important prey for tertiary consumers including marine mammals, large fish, and seabirds. Long-term research studies allow for scientists to study the relationships between hydrographic data such as sea surface temperature, salinity, and density and the abundance and geographic distribution of forage species over decades, and in the case of this survey, three decades. An ecological rearrangement of forage species can affect not only the tertiary consumers and apex predators such as orcas and great white sharks, but will also impact the fishing industry. It is important to understand the impact of warming oceans and weakened California upwelling events have had and will have on the diversity and health of the ecosystem of the Pacific Coast.
Mission: Rockfish recruitment and ecosystem assessment survey
Geographic Range: California Coast
Date: June 29, 2018
*Update from previous blog*
I mentioned in my previous blog that one of our scientists was analyzing water samples for sea turtle eDNA. Here is what she added about her research…
“Kirsten Harper, a postdoctoral researcher with NOAA/AOML, collected water to analyze for environmental DNA (eDNA). This is DNA that might be left in the air, soil, or water from feces, mucus, or even shed skin of an organism. In her case, she is trying to detect the diurnal vertical migration of fish species, such as sardine, using eDNA. Additionally, she is using eDNA to detect the presence of leatherback turtles. Very little is known about leatherback turtles in the open ocean, as they are difficult to find and survey. eDNA could help solve this problem!”
I officially left the Reuben Lasker on the morning of June 11, 2018 via small boat transfer. While I was looking forward to getting back to family my students, I realized I wasn’t quite ready to leave the ship and the work behind. I finally felt integrated into the team and the work, and that quick it was over. I definitely wanted to stay!
The small boat transfer was fun; it was the fastest speed I traveled in over a week. We also spotted dolphins on the way into shore. Once on land, I had the opportunity to meet with Emily Susko, Program Specialist for NOAA TAS. I had almost a full day to spend on land, and [I believe] Emily knew I had only been to California once before for a very short visit. She was an awesome host and decided to show me some really cool attractions that were more first-time experiences for me.
The first place we visited was the Henry Cowell State Park, a well-known location for exploring redwood forests. I am not sure I ever knew the difference between the coastal redwoods and the giant sequoia redwoods; I now understand the coastal redwoods are the smaller of the two species. Nonetheless, there were still the biggest trees I think I’ve ever seen. I also had the chance to test some of my birding skills. I do not know Pacific coast species as well, but some calls sound similar to east coast species, and I feel pretty confident in saying I heard and saw chestnut-backed chickadees, a species we do not have in Philly.
The second place we visited was Natural Bridges State Beach. This was another equally exciting experience for me because, again, it was so different. On the east coast, the land is pretty flat along the ocean. Therefore, our coast is lined with salt marshes (another one of my favorite places). Being able to see the rocky coasts in Santa Cruz was cool because it’s something I’ve only seen in pictures. When we teach beach ecology, we use this coast as an example because the ecological boundaries are so visually obvious, and I saw it for the first time in person. We explored some of the tidal pools, and they were teeming with little organisms. Now the next time I teach about them in class, I can use my own pictures!
Long story short, I had a blast! I am so genuinely grateful for the opportunity to participate in something like this. As someone who started out in Marine Biology, it is near and dear to my heart. I like to think I knew a few things coming in, but I learn so much during this trip. I learned about how much has changed since the last time I did this type of research, like the importance of being able to read and write programming language to analyze data. I personally enjoyed working with people whose work has the potential to impact the environment and people alike. I also learned a lot about how many people it takes to get the work done. It included every individual on the ship, no matter his or her role.
It’s been a few weeks since I returned from my cruise. I had some time off to catch up with home life, and then had to get back in the office and prepare for the summer. Since our program is an out-of-school program, we are running programs and opportunities year-round. I have a group of Seniors who completed the program, the current 9th-11th grade students move up a grade, and we have a brand-new group of rising 9th grade students beginning the WINS journey. Everyone, from family to colleagues to students, has been asking to hear about my experience. I have a few dates in place to present what I’ve learned and how they too can get involved. I am looking forward to the next stage of the process, writing the activities based on my experience.
I especially want to thank everyone from the Science Team, all of the NOAA Corps. Officers, and the crew of the NOAA Ship Reuben Lasker. I truly enjoyed my time while aboard the ship, and appreciate that you all welcomed me and treated me with kindness. I hope this is not my only visit to the Reuben Lasker!

As you may have gathered from my previous blogs, I spent my time working with the night scientists. However, there was a lot happening during the daylight hours that I would like to highlight. There was a separate team assigned to the day shift. Some of their tasks included analyzing water samples, fishing, and surveying marine mammals and seabirds.
Catching fish during the day allowed them to see what prey were available to diurnal predators, and they could also compare their daytime catch to the evening catches. They used a different net called a MIK Net, which is a smaller net used for catching smaller and younger fish.
The day shift is also the best time for spotting seabirds and marine mammals. Some of the bird species spotted included brown pelican, common murre, terns, black-footed albatross, shearwaters, and at least 1 brown booby. The marine mammals we spotted included humpback whales, fin whales, blue whales, common dolphins, and sea lions.
I had an opportunity to speak with Whitney Friedman, a postdoctoral researcher with NOAA, and she explained to me some of the goals of their marine mammal survey. Many may recall that there was a time when whale populations, especially humpback whales, were in significant decline. Today, humpback whales are considered a success story because of rebounded populations. The concern now is monitoring the success of their food sources. Humpback whales feed on krill and fish like anchovies. However, it is possible that when these sources are less available or as competition increases, they may feed on something else. The question is, what is that something else? During this survey, one goal was to collect whale scat for analysis. Studies have found that some seabirds feed on juvenile salmon incidentally when their preferred local prey is limited, and they move inshore to feed on anchovy. Is it possible that whales might do the same? What else might they be foraging on? Unfortunately, we did not have much luck catching whale scat this time around, but they will try again in the future, and hopefully will find the answers they are looking for.
As previously mentioned, we also did water quality tests and took water samples using the Conductivity, Temperature, and Depth (CTD) Rosette. This instrument has multiple functions. As the initials suggest, it detects conductivity (the measure of how well a solution conducts electricity) and temperature at any given depth. Salinity (the amount of dissolved salts and other minerals) and conductivity are directly related. By knowing the salinity and temperature, one can determine the density. Density is one of the key factors that drives the ocean currents. Many species depend on the ocean currents to bring in nutrients and food. It all comes full circle.
When we lowered the CTD we could also take water samples at any given depth. This allowed scientist to test for various parameters. For example, we filtered various water samples to determine the amount of chlorophyll at certain depths. This can help scientists estimate the growth rates of algae, which in the open ocean are called phytoplankton. One of the scientists collected water to analyze for environmental DNA (eDNA). This is DNA that might be left in the air, soil, or water from feces, mucus, or even shed skin of an organism. In her case, she was trying to find a way to analyze the water samples for sea turtle DNA.
I’ve heard of eDNA, but I have never actually understood how they collected and analyzed samples for this information. My understanding is that it can be used to detect at least the presence of an extant species. However, when collecting these samples, it is likely to find more than one species. Scientists can use previously determined DNA libraries to compare to the DNA found in their samples.
We started trawling again on the evening of June 7th. By then we settled ourselves into the protection of the Monterey Bay due to the weather getting bad. While we still had some off-shore stations, we tried our best to stay close to the bay because of the wind and swells. We had some interesting and challenging trawls in this area: lots of jellyfish. Some of the trawls were so full we had to actually drop the catch and abort the trawl. If not, we risked tearing the net. We tried to mitigate the overwhelming presence of jellies by reducing our trawls to 5 minutes instead of 15 minutes, and we still had similar results. One night, we had to cancel the final trawl to sew up the net. I’ve been told that sewing a fish net is an art form. Our deck hands and lead fisherman knew exactly what to do.
Let me tell you my experience with jellyfish during the survey. As you may recall, someone must be on watch for marine mammals on the bridge. This is the ship’s control room that sits on the 5th level above water.
From here you can see the surface of the water quite well, which makes it a great spot for the marine mammal watch. It was also great for watching hundreds of moon jellies and sea nettles float right by. It was one of the coolest things to watch. It was somewhat peaceful, especially hanging your head out of the window, the cool air blowing against your face, and the occasional mist of sea spray as the ship’s hull crashes against some of the larger swells. However, that same peaceful state disappears the moment you realize, “I’m gonna have to lift, count, and sort all those jellies!” I wasn’t too concerned about being stung; we had gloves for the sea nettles and the moon jellies were no real threat. However, the sea nettles (Chrysaora fuscenscens) smelled AWFUL, and the moon jellies (Aurelia spp.) are quite large and heavy. I’m honestly not sure how much they weighed; we did measure up to 20 per haul, some of them measuring over 400 mm. Even if they weighed about 5 pounds, lifting 50-60 of them consecutively until the count is complete is enough to get the muscles burning and the heart rate elevated. It was a workout to say the least. I was literally elbows deep in jellyfish. I also wore my hair in a ponytail most of the time. Anyone that knows me knows well enough that my hair is long, and definitely spent some time dipping into the gelatinous goop. I smelled so bad! HAHAHAHA! Nonetheless, it was still one of the most intriguing experiences I’ve had. Even though the jelly hauls proved to be hard work, I enjoyed it.
In those last few days, I felt like I became integrated into the team of scientists, and I felt comfortable with living out at sea. I had a few moments of nausea, but never really got sea sick. I still couldn’t walk straight when the ship rocked, but even the experts wobbled when the ship hit the big swells. Then, that was it for me. By the time I got the hang of it all, it was time to leave. I wish there were more hours in the day, so I could have experienced more of the day time activities, but I still got to see more than I thought I would, and for that I am grateful.

NOAA offers many career options. As a scientist, here are some things one might study:
track and forecast severe storms like hurricanes and tornadoes; monitor global weather and climatic patterns
Research coastal ecosystems to determine their health, to monitor fish populations, and to create policies that promote sustainable fisheries
Charting coastal regions and gathering navigational data to protect the ship from entering unsafe waters
NOAA Corps allows one to serve as a uniformed officer, commanding a ship or piloting aircraft. On NOAA Ships, they need engineers, technicians, IT specialists, deck hands, fishermen, and even cooks (The Reuben Lasker had two of the best, Kathy (Chief Steward) and Susan (second cook)). There are many opportunities available through NOAA, and there is a longer list of amazing experiences one can have working for this organization.

Mission: Rockfish recruitment and assessment survey

Science and Technology Log
We moved up north to continue with our trawls. The first night we trawled just north of Monterey Bay. It was a good thing we did because outside the bay, the wind and swells are rough. We saw lots of jellyfish and lots of krill in our catches. However, I would like to talk a little about a very specific group of fish, rockfish. If you read the mission above, you will recall that rockfish are the primary focus of this survey. Therefore, I think they need a moment in the spotlight to themselves.
While this number may vary, NOAA has over 60 species of rockfish listed on the West Coast. They are an intriguing group of fish for many reasons. First, it is important to note that they are extremely significant to their food web because they are a prey species, but they are also important as a food and income source for humans. Species like the bocaccio rockfish and the yelloweye rockfish are species of concern due to over fishing, and populations are slow to recover. That is enough reason to learn as much possible about these fish.
What we know about rockfish species is they can live for a long time. Many can live over 50 years, some can even live over 100 years of age! Their growth rate is relatively slow, and very few make it to adulthood because they are prey for other fish. During the first year (sometimes more depending on the species), they spend much of their time in the pelagic realm (open water). If they live long enough, they can grow to a size that allows them to settle in the benthic zone (ocean floor). For many species, 60 mm is a large enough size to settle. This is what the term “recruitment” refers to. Once rockfish settle out of the pelagic zone, they have a higher chance of reaching reproductive maturity.
NOAA Fisheries has been surveying the West Coast for rockfish since 1983. They first started in a smaller region from Monterey Bay to Point Reyes, CA. The survey area expanded in 2004 and by 2013 it covered the entire coast of California. The success of the local ecosystem and the commercial fisheries depend on healthy fish populations. The survey tries to collect at least 100 specimens per species of rockfish and take them back to the lab (on land). Back at the lab the species identifications are determined as many rockfish are difficult to identify to species at this life history stage without using a microscope. In addition, their size is recorded and tissue samples taken for genetic studies. Then, on select species, otoliths are removed to age the specimens. The otolith is an ear bone. In fish, the ear bone deposits layers of bone in rings. It happens daily and these daily rings can be counted using a microscope to learn how old the fish is. These ages are used by scientists not only to learned how old the fish are, but they can compare this information to the size data collected and estimate the expected size of a fish at any given age.
I had a chance to talk to everyone from the night shift science team about what they do and how they came to work for NOAA:
Keith Sakuma has been working with the survey since 1989. He is the chief scientist and team leader of the night crew. He works hard to make sure we are all focused and efficient because it is a fast-paced work environment. In between hauls, he enjoys the company of his team and a few Dragon Ball episodes. He was born and raised in Hawaii, and went to University of Hawaii for his Bachelor’s degree in Zoology. In his younger years, Keith worked for the Division of Aquatic Resources, where he spent his days walking up and down the beach to count fisherman and interview them about their catches for the day. He also did snorkel surveys doing fish counts in fisheries management areas. In addition, he worked on a team that implemented fish aggregating devices, buoys that attract fish for the local fisherman.
While at the University of Hawaii, he was part of the Marine Option program where they teach you various marine skills and connect you with marine research activities. Through this program he completed his scientific diving training, and then participated in two diving surveys. Both surveys documented the impacts of tourism on the reef systems on the island of Lanai Island and Molokini, which is a tiny islet off Maui. On Molokini, tourist traveling to the islet by boat, dropping anchor in the reef, caused a significant amount of damage to the reef. Mitigation included the addition of moorings so boats could tie up and not have to drop anchor, destroying more of the reef.
For his Master’s, he attended San Francisco State University. His major advisor just returned from a 2-year sabbatical, working with the National Marine Fisheries Service (NMFS) [also known as NOAA Fisheries] on the mid water trawl survey, and suggested that Keith do his Master’s Thesis on the data he collected on the survey. While finishing his Master’s degree, he was offered a full-time position working with NMFS, and has been here ever since. That means he has 29 years put into this work.
Growing up in Hawaii near the ocean definitely influenced his decision to pursue Marine Science. He used to say to others how much he loved the ocean and that the ocean loved him back. He couldn’t wait to spend time at the beach in the water. And while today this remains true, he has mentioned that that cold waters of Pacific Coast are not as affectionate as the warm waters of Hawaii. The water around the islands is so clear, allowing one to see at a distance the beauty that lies beneath. Here, you must pick the right day at the right time to find tolerable temperatures and some visibility. The murkiness makes it hard to see anything, but that murkiness is what contributes to the productivity of the region.
Even after 29 years, Keith still very much enjoys being at sea. He doesn’t get sea sick, so he can spend time working in the field with real specimens and real-time data rather than just analyzing data collected by other people. He enjoys seeing new people come on and get excited about the work. For anyone interested in pursuing Marine Biology and any research science, it is important to have a strong background in math and statistics, especially in today’s world. He also mentioned how important it is to have computer skills and programming skills. The software used to process and analyze data requires one to read and write programming language. Having these skills make one a stronger candidate when applying for research positions. It also gives one more validity when having to speak about and defend the analysis of the research.
That’s Keith, the Chief Scientist, in a nutshell. I also got to learn more about the rest of the team. Thomas Adams has been working with this survey for 5 years now. He started as a volunteer with NMFS, analyzing marine chlorophyll samples. He always had an interest in Marine Biology, and already had a connection to someone working in a NOAA lab. He was invited to work on the rockfish survey because he was known for being a knowledgeable and efficient worker. He too is very enthusiastic and really enjoys being at sea with Keith and the rest of the team. He is the main provider of Dragon Ball, and the Simpsons, which the team enjoys in between trawls. He recently completed his Bachelor’s degree and plans to go for his Master’s in Marine Biology in the near future.
Melissa Monk is a Research Mathematical Statistician, and is responsible for fisheries stock assessments for West Coast near shore ground fish. She also participates in research related to improving fisheries. Her schedule is on a bi-annual cycle. One year is devoted to stock assessment, and the next year is devoted to research. During stock assessment years, there is a mad dash that happens around September to learn anything and everything about your assigned species. At the end of the assessment season, there is a week-long panel review of all the data gathered during the assessment. Once the assessment is approved, the information is used for species management and harvest regulations. She received her undergrad in Wildlife Sciences with a minor in Statistics. Her Master’s was in fisheries. She spent half her year monitoring the sea turtle populations in North Carolina, and the other half of the year in classes. She did a lot of quantitative work, research, and recruitment training for her Master’s. She also had a connection to NOAA because her PhD advisor at LSU used to work for NOAA. She learned that NOAA trained people to become stock assessors, and pursued fisheries as a career. Her favorite part about working for NOAA is that her work directly impacts fisheries success.
Rebecca Miller is a GIS Specialist, works on a variety of projects at the Santa Cruz NOAA lab. One project is the spatial mapping of rockfish and other marine species. She maps California fisheries catches in both time and space, and is able to analyze this data as far back as the 1930’s. Her Master’s degree is from Oregon State University in Fisheries Sciences with a minor in Geography. She knew since 6th grade that she wanted to be a Fisheries Biologist. She participated in internships and part-time summer jobs in freshwater salmon fisheries, marine intertidal work, and geodatabase management. She loves the people she works with, and the fact the work is so diverse. There is a lot of field work, lots of data analyses, and different projects to work on. She too enjoys knowing that her work helps to sustain fisheries to be both utilized and conserved.
Stephanie Oakes is from NOAA Fisheries Office of Science and Technology (OST). She got her Ph D. in Marine Sciences, and worked on Antarctic krill in an ecosystem context. The rockfish survey is similar in the sense the it also surveys species in an ecosystem context. Being able to participate in surveys like this is important to her because she gets to experience first had what happens during the surveys and how the team operates. Her personal gratification is that she gets her hands in the catch, in the field like she did for her Ph.D. NOAA Fisheries OST is there to advocate and ensure sound scientific basis for NOAA Fisheries science programs and resource conservation and management decisions.

Science and Technology Log
Our first official night on the Job was Sunday, June 4th. My shift is technically 6:00 pm to 6:00 am, but we could not begin trawling until the evening when skies were dark. If fish can see the net, they can avoid it. The method we use to catch fish is a midwater trawl, also known as a pelagic trawl, because the net fishes in the water column. It’s called a modified Cobb midwater trawl net. It has a cod end, the narrow end of a tapered trawl net where the catch is collected during the trawl.
Before we lower the net, the water around the ship must be clear of marine mammals. Thirty minutes prior to each trawl, someone stands the marine mammal watch on the bridge. Once the net is deployed, someone must be watching for marine mammals outside the entire time. If any marine mammals are spotted (this includes dolphins, porpoises, seals, and sea lions), we report it to the officer on the bridge. The rule is that if we spot a marine mammal, the net must be hauled back in and we sail a mile away from the sighting. Marine mammals are protected and we do not want any caught in the net.
When the net is in the water, we trawl for 15 minutes at 30 m deep. Optimal speed is about 2 knots, but that is weather dependent. During this time, our deck crew, and Survey Technician monitor each step of the haul, reporting back to the officer on the bridge. As they haul the net in, the deck hands and Survey Technician work together to make sure the catch goes into the bins for sorting.
I didn’t know what to expect from our first catch. Maybe we would have some fish, crabs, squid…However the first catch brought something I never saw before. Lots of Thetys!
Thetys are a type of salp. Salps are planktonic, colonial tunicates from the phylum Chordata. We also had pyrosomes, another type of colonial tunicate. They are efficient feeders, filtering particles of plankton from the water. It is expected that in areas where salps are prevalent, one can expect to find less of other species from the same trophic level. For this catch, that happened to be the case.
As of today, I officially completed 3 shifts on the job, which included 12 trawls in total. It seems that each catch was dominated by 1 or 2 species. There were other species present, but we had to sort through the catch to find them.
We had a catch that was loaded with anchovies, another with krill, and one full of pelagic red crabs. I find this to be one of the most interesting parts of the work, anticipating what we will find. There are many variables that can impact the productivity of an ecosystem, and therefore can determine what we find. Things like salinity, sea surface temperatures, upwelling, proximity to land or open ocean, and human impact, can all influence an ecosystem.
So, what do we do with our catches once we have them? We count them, and there is a method to the count. Depending on the size of the catch, we may measure out 1,000 ml, 2,000 ml, or 5,000 ml. We start with that first bucket and count every individual (species like krill or salps are measured by volume). The numbers are reported to Keith Sakuma, our chief scientist, and recorded in a handwritten data sheet, then transferred to an excel document. After the first bucket, we may focus on sorting for all other species except the predominant species. For example, for our large anchovy catch, we sorted through approximately 60 liters of fish. We didn’t count every single anchovy, but based on our primary count, we can use the total volume to estimate. However, we sort through looking for all other species and record the findings.
We will record each species we find, and then we have a list of specified species that need to be measured. We take the first twenty specimens of each so we have a record of the average size fish caught in that specific location and time. We focus on measuring the species of fish that have the most ecological and economic importance. These are the prey and those that are consumed by us. Therefore, they are also likely to suffer from human impact. Learning about these species are important to the understanding of what makes them successful, and how to mitigate the things that negatively impact their productivity.
So far this is our routine. Tonight, we had a break from trawling as we transit up to Davenport, just North of Santa Cruz. The current conditions are not favorable for trawling, so we will get back to work tomorrow evening. While we take it easy, our NOAA officers navigate the ship up the coast. I had the opportunity to speak to our Executive Officer (XO), Lieutenant Commander Emily Rose.
How did you come to work for NOAA?
I went to the University of Hawaii and got my degree in Meteorology. From there, my friend referred me to someone who currently worked in the NOAA Corps. The things she told me about the job piqued my interests, so I applied. I was selected in 2008. There was a 5-month training period, and then I was stationed in Hawaii on the Ka’imimoana, a ship that has since been decommissioned. I was sent to Santa Rosa, CA to work for National Marine Fisheries Service (NMFS) during my first land assignment, then I became the Operations Officer aboard the Okeanos Explorer. Before I joined the Reuben Lasker, I was stationed at the National Centers for Environmental Information (NCEI) in Boulder, CO for 2 years.
Since you have a degree in Meteorology, do you get to use what you’ve learned for your current position?
Every time I’ve been on a ship, I’ve been the defacto weather officer. On the Reuben Lasker, I haven’t had to do too much with weather so far, but on other assignments I’ve done weather presentations and helped others like the CO (commanding officer) interpret weather patterns, and just to provide information to those who are interested in learning. It’s is not a career in Meteorology, but having a degree in a science that relates to what NOAA is beneficial. You use critical thinking skills throughout the job. If there is a challenge, you can come up with a solution. You also have math and physics, and a basic understanding of how things work. All these things help make operations successful.
What is the most important part of your job now?
The most important part of my job is to manage the ship’s crew. I make sure they are put first. I manage their time and attendance, their pay, their leave time, any personnel issues, etc. Anything they need, I am there for them. They are the reason we (the ship) are successful.
What is your favorite part of your job?
All of it! The variety. My job changes from day to day; there are new challenges each day. The variety makes it interesting.
What tool is the most important for you to do your job?
For me I would not be able to do a good job if I did not have a positive attitude. Sometimes we are faced with challenges that are not easy to fix without support and understanding. Having a positive attitude helps me get through it and helps others around me.
I also think it is important to be open-minded and be willing to try new things. There is a lot that we deal with that some have never dealt with before. Having an inquisitive mind and ability to be ready for anything are important.
When you applied for NOAA, did you know this is what you wanted to do?
Yes. Once I applied, I thought it would be pretty cool. I was also thinking about being a math teacher, or to pursue weather in the air force. I’m glad I didn’t because I get to do a whole lot more here than I would if I were in an air force weather center. Once the application process got rolling, and then I got an interview, I thought “Yeah, this is what I want to do.”
Was there something you found surprising about your job when you started?
There were a lot of surprises! You always have an idea of what you expect, but once we all got together for training, we learned something new every day. Some of us had never been on a ship before, some have never driven a small boat, some have never done any charting. And I still feel like I learn something new each day. Everybody that I’m around has a different background and experience, so it’s fun to learn from them.
If you weren’t working for NOAA, what would you be doing now?
I don’t think I would be doing something else. I don’t feel like I’ve missed out on something. In fact, I tell people all the time about what they are missing! I’ve got to do more in this job than I ever thought I would. I’ve been all over the world, included places like Western Samoa, The French Marquesas, and the Marshall Islands.
If you were give advice to a young person considering a NOAA career, what would you recommend?
Anyone who is interested in going into NOAA as a scientist, crew member, or Corps Officer, one important piece would be to study hard and work hard, but keep in mind, grades are not the end-all be-all. Try hard and learn the material, and learn how to problem solve. Don’t be afraid of a challenge, and be ready to give 110% because that will help get you to the next level. For NOAA Corps specifically, having some experience working on a ship and understanding of nautical operations is beneficial. And don’t be afraid to reach out to someone from the NOAA Corps because they are willing to offer guidance.
What are your hobbies?
Sports! I play any sport that you ask me to, but I play on teams for soccer, softball, ice hockey, tennis, and a basketball league not too long ago. When I’m on land, I join as many teams as I can. I love riding my bike. On my last land assignment I went two years riding my bike to work and didn’t drive at all. My husband even bought me snow tires. You name it I’m game!
Did You Know…
Before you can set out, you must have multiple permits. Depending on where trawling occurs, one may need a permit for state waters and federal waters. Those conducting research may receive permits to trawl in both state and federal protected areas.
We keep some of the specimens for further analysis in the lab (back on land). There are various reasons scientists want to study further, including learning about their genetics, development, and reproduction. One group includes all the juvenile rockfish we find. Please stay tuned for the next blog to learn more about this part of the research.

Science and Technology Log
I arrived on NOAA Ship Reuben Lasker on Wednesday, May 31st. However, we just left the Port of San Francisco last night (June 2nd) because the ship had to make sure everything was running properly and pass multiple inspections. Safety is a serious thing out here, and I appreciate that very much. Once we had the green light, we sailed out of San Francisco Bay underneath the Golden Gate Bridge. The winds were about 25 knots (almost 29 mph) with 10 foot swells. Conditions like this are not ideal for data collection, so we sailed about 220 nautical miles to the South where conditions were more promising. I spent my first night on the job acclimating to the evening schedule. In that time, I learned about some of the equipment and programs we use to collect and analyze our catches and samples.
The first thing that I noticed was a GPS system used to track the ship’s location and the locations for each trawl. The boat icon shows the location of the ship, and the dots indicate locations where we plan to survey. Those with a triangle inside are the trawling locations, while the others indicate spots where we need to perform CTD tests. This systems marks locations using latitude and longitude, and can provide an estimated time of arrival.
The second program I learned about was NOAA’S Scientific Computer System (SCS). This system allows the ship to record a variety of environmental and positional data immediately into the computer. While some data is still recorded by hand, this system reduces human recording errors, in turn allowing for analyses that accurately represent the data collected. I also had the opportunity to interview our Survey Technician, Jaclyn Mazzella. Jackie is one of the NOAA Crew members on board, but she is also one of the most important people that serves as a liaison for both the scientists and the crew. Read the interview below:
What are the responsibilities of the Survey Technician?
The Survey Technician is responsible for data management. All the data collected on the ship is recorded in the Scientific Computer System Database. This includes data from the thermometers, anemometer (wind speed), TSG (thermosalinograph), fluorometer, etc. The data is organized and then delivered as a data package to the scientists. There are two major types of files, continuous files and snapshot files. A continuous file may include data that is taken every 30 seconds, like latitude and longitude, speed over ground, course over ground, etc. A snapshot file provides information about a very specific event. For example, their system records every single step in the trawling process, including the moment the net hits the water, “shooting the doors” that hold the net open, begin fishing, and then every step in the return of that process. While this is happening, all the environmental parameters are simultaneously and continuously being recorded. Jackie maintains these files until the end of a survey and then gives the data to the chief scientist in a document known as the MOA, or the Marine Operations Abstract. The information is also sent to the National Center for Environmental Information, the world’s largest active archive of environmental data. These archives are available to the public.
Why did you apply to work for NOAA?
At first, I didn’t know what NOAA was. I originally wanted to study things like Marine Biology, Astronomy, and Physics. I was attending the Borough of Manhattan Community College as a liberal arts major. I planned to transfer to another school for Physics and Astronomy, but my counselor suggested another option, knowing my interest in Marine Science. I then went to SUNY Maritime in the Bronx to study Marine Environmental Science (State University of New York), a school I never knew existed considering I lived right down from the street from it. Upon graduation, I received an email from a former classmate also working for NOAA, stating that NOAA was seeking Maritime Majors for this position. She gave me a contact, I sent my resume, and I got the job.
What is the most important tool you need to do your job?
The SCS is the most important thing I need, and am fortunate that NOAA Ship Reuben Lasker has up-to-date, top-of-the-line equipment. We are one of the most technologically advanced ships in the world. We also have back-ups for almost everything on board which is nice to have while at Sea.
What advice would you give to someone interested in pursuing this position as a career?
Being a Survey Technician requires you to have a degree in science. Be certain that if you apply for a position, be sure to know what you are applying for. Much of my training was on the job training, and I was fortunate to work with Phil White, Chief Survey Technician with years of experience. I learned a lot from him. Phil also developed course for those wanting and needing to learn the ins and outs of a Survey Technician.
If you didn’t work for NOAA, what career would you choose?
Working in Astronomy or Physics because I had a strong interest in both. However, I would say that joining NOAA was one of the best decisions I ever made. I came from a rough background growing up, and now I get to experience things I never would have imagined. NOAA provides an acceptable salary, nice benefits, leave time, vacation time, and paid overtime. When I take leave, I travel to other countries. This is something I always wanted to do.
What are your hobbies?
I love trying new foods when we go in port. I love drawing, painting, and playing video games. And I love to travel. I’ve already been to Egypt, Qatar, Europe. In the next year for two occasions, I plant to travel to Italy, then [for my honeymoon] to Vietnam, Cambodia, Thailand, and the Maldives.
Analyzing data can be a daunting task. “R,” a coding language used for statistical computing and graphics, allows scientists to analyze their data in a variety of ways. The program can be used to perform statistical computations of large amounts of data to show underlying patterns and trends. It can also be used to create plots of specific sects of data if one wanted to highlight a location or time. Many scientists like this program because it is very user friendly, and if one needs help with a program (code), there is a free and open community of users available to provide advice and feedback.
When I arrived at the NOAA Ship Reuben Lasker, we expected to sail on May 31st. However, we were delayed in port for 2 extra days, officially leaving port on June 2nd. During the waiting period, I explored the piers along the Embarcadero. I had the chance to visit the Exploratorium, the Bay Aquarium, and the famous Pier 39. Pier 39 is where the Sea lions aggregate every day and, apparently, have been doing so for 28 years.
I hiked up the stairs to Coit Tower, a historic landmark built in 1933 (Lillian Hitchcock Coit, a rich socialite, bequeathed over $100,000 back in 1929 to restore and beautify sections of San Francisco). Hey WINS girls, remember how we climb the steps coming out of Tumbling Waters, and how you felt like you were going to die before you reached the top…I almost died twice climbing those stairs! By the second time it was easier.
When on the ship, I would read or sit out on deck and watch the pelicans, gulls, cormorants, terns, and common murres. I also got to do a little bird watching heading to Coit Tower, where I saw lots of Anna’s humming birds, chestnut-backed chickadees, and song sparrows. It was interesting because I don’t recognize the calls of west coast birds. Even the song sparrow, which are also common Philadelphia, have a variation in their song, like an accent or a dialect.
As of June 2nd, we have been out to sea. I’ve been assigned to night shift, which means I will be working a lot on sorting the overnight hauls (Stay tuned for the next blog). However, the weather leaving the bay on the first night was rough, so we sailed south to find calmer waters. I didn’t mind so much because as soon as we passed the Golden Gate Bridge, I got to see something I wanted to see my whole life, humpback whales! It was worth the wait.
Mission: Rockfish Recruitment and Ecosystem Assessment Survey
Geographic Area of Cruise: Pacific Ocean along the California Coast
Date: May 25, 2018
Introductory Personal Log
One time, I had the chance to visit California for a conference, and I got to dip my feet into the Pacific Ocean. It was so cold! In less than a week I will be surrounded by Pacific waters as I set sail on NOAA Ship Reuben Lasker for 12 days. The anticipation has been building since I learned of my assignment, and now the time has finally come.
My name is Kimberly Godfrey, and I am the Coordinator of the Women In Natural Sciences (WINS) Program at the Academy of Natural Sciences of Drexel University (yes, that it a mouthful). The Academy (1812) is the oldest natural history research institution in the Western Hemisphere, and WINS just celebrated 35 years. WINS is a science enrichment, after-school program for high school girls in public and charter schools in Philadelphia. Our goal is to provide opportunities for exposure to the natural sciences in ways the students cannot find in the classroom. Our long-term goal is that they take what they learn and turn it into a career. Most of our participants have had little to no real-world, hands-on science in the classroom, and they share many first-time experiences with the WINS staff and other participants.
That’s my favorite part of being a WINS girl. I can share my experiences and my knowledge with them. I have a degree in Marine Biology, and had the opportunity to participate in marine mammal research for 2 years. I taught about environmental science and wildlife conservation for 10 years prior to working at the Academy. And, something that is important to me, I am a Philadelphia native who, like these young ladies, knew little about my urban ecosystem while growing up in the city (the only eagles I ever saw growing up were the Philadelphia Eagles, you know, the 2018 Superbowl LII Champions! You may have heard it a time or two). It wasn’t until I returned from college that I began to explore the world right under my nose. Now I help them explore the wildlife in their backyard, and then push them to branch out of the city, the state, and even across the globe.
Over the past few weeks, I found it difficult to refrain from talking about my upcoming trip. I shared the information I’ve learned so far with some of my girls, and each time I share something new, they become equally excited to follow my adventure at sea. I met with one of the Academy’s fisheries scientists, Paul Overbeck, to learn how to remove an otolith. Some of my preparation stories have led to a lot of joking and humor. For example, trying on every pair of waders, boots, and waterproof gear that we have, all of which are too big for my size 5 shoe and my 5’0” height; how my freshly caught blue fish dinner turned into a dissection in my kitchen as I practiced removing the otoliths; or how I randomly had the opportunity to meet Sian Proctor, 2017 TAS participant and face of the 2018 TAS application (she happens to be friends with one of my co-workers)! All of this leads to one very anxious and excited woman ready to set sail.
Quite a few of our girls wish to explore Marine Science as a career, so my plan is to absorb everything I can and bring it back to them. I want them to know the importance of this research, and that this career is truly an option for any one of them. One day, I would love to see a WINS girl aboard a NOAA research vessel, dedicating their careers to the understanding and stewardship of the environment. That’s what NOAA’s mission is all about!
Did you know?
Scientists working with NOAA and the Southwest Fisheries Science Center have been conducting surveys along the California Coast since 1983. Along with rockfish (Sebastes spp.), they’ve been collecting abundance data and size information on other species including Pacific Whiting (Merluccius productus), juvenile lingcod (Ophiodon elongatus), northern anchovy (Engraulis mordax), Pacific sardine (Sardinops sagax) market squid (Loligo opalescens), and krill (Euphausiacea). The information gathered from these studies is used to examine recruitment strength of these species because of their economic and ecological importance.

Science and Technology Log:
A week has passed since I left the Reuben Lasker, but I have continued to monitor the haul reports from the ship. The last haul report indicates that haul #79 of the West Coast Pelagics Survey was conducted off of the coast of California just south of San Francisco Bay. The survey is fast approaching the concluding date of August 11th when the Reuben Lasker is scheduled to be in port in San Diego. Based on their current location, there are probably only a couple of days/nights of sampling left for the survey before the ship has to steam for its home port of San Diego.
As I looked through the spreadsheet with the summary of the data that is being collected for the survey, I can’t help but be impressed by the volume of data and the efficiency in which it is being recorded. Although I was only on the ship for a short period of time, I know how much work is involved in preparing for the evening trawls and how much time it takes to process the catch and record the data. I have a tremendous amount of respect for the talented, dedicated, hard-working science team members aboard the Reuben Lasker. Below is a series of interviews with many of the science team members that I had the pleasure to work with while I was on the ship.
Each team member was asked the following 3 questions:
Q1: Can you tell me a little bit about your background, including education and work history?
Q2: What have you learned from your time on the Reuben Lasker during the 2nd leg of the Pelagic Species Survey?
Q3: What advice would you give to a 1st year college student that was interested in pursuing a career in marine science?
Science Team Member: Phill Dionne

Q1: Phill’s post-secondary academic career started at Stoney Brook College in New York where as an undergraduate he studied Geology. Phill’s undergraduate program also included time in Hawaii where he took several courses towards his minor in Marine Science. After his bachelor’s degree, Phill spent a year in the Florida Keys, initially as an intern, then as a marine science instructor at a science camp. As Phill continued to pursue his educational goals he began to focus on marine science as a career pathway. Ultimately, Phill completed a graduate degree program at the University of Maine where he studied the migrations and abundance of ESA listed sturgeon and earned masters degrees in marine biology and marine policy.
Phill moved to the state of Washington in 2011 where he currently works for the Department of Fish and Wildlife. Phill’s current positon as Senior Research Scientist includes overseeing programs centered on habitat and stock assessments for forage fish including surf smelt, sand lance and Pacific herring.
Q2: When asked what he had learned during his time on the Reuben Lasker, Phill pointed to gaining a better understanding of the techniques and challenges associated with managing coastal fisheries, and how they differ from nearshore survey techniques.
Q3: Phill’s advice to first year college students considering a career in science is to get experience in data management and to get involved in internships early in your academic career. Phill also emphasized that it is important to understand that a career in marine science is more than just a job, it is a “lifestyle” that requires commitment and hard work.
Science Team Member: Andrew Thompson
Q1: Although originally from California, Andrew earned his graduate degree from the University of Georgia where his studies focused on stream ecology. Eventually Andrew would earn his PhD from the University of California in Santa Barbara. As part of his work for his PhD, Andrew studied a unique mutualistic symbiotic relationship between a species of shrimp and shrimp gobies (fish) on tropical reefs near Tahiti. In this unusual relationship there is a system of communication between the fish and shrimp in which the fish acts as a type of watchdog for the shrimp communicating the level of danger in the environment to the shrimp based on the number of tail flips. After a stint with the United States Fish and Wildlife Service in California, Andrew began working for NOAA in 2007 where he specializes in identification of larval fish.
Q2: Having experienced multiple assignments on NOAA research vessels, Andrew’s response to what he had learned while on this cruise related to his enjoyment in watching the younger volunteers see and experience new things. He voiced an optimism in the younger generation expressing how many “good, talented kids are coming through programs today.” One of the observations that Andrew pointed out about this survey was the number of pyrosomes that are being found which is uncommon for this geographical area. In a bit of an unusual find, a juvenile medusa fish within a pyrosome also sparked Andrew’s interest (see photo above).
Q3: With regards to advice for prospective students, Andrew pointed out that a career path in science is often non-linear. Like many of the science team members that I interviewed, he talked about how important it is to persevere and push through the difficult times as you pursue your goals.
