Scientific Log:

On Sunday we encountered heavy fog as soon as we headed out to sea, so the captain sounded the foghorn every 2 minutes. The scientists Jaime, Ryan and Kirsten deployed the Tucker Trawl. It consists of a large net with 3 codends. A codend looks like a small cup that attaches to the end of the net. Each codend collects sea life at a different depth. The Tucker Trawl is always deployed at the edge of the continental shelf. The shelf is about 200 meters below sea level. The goal is to take organism samples from the pelagic (non-coastal or open) ocean. 400 meters of cable are deployed along with the net, so you can see that it goes deep in the ocean!

The scientists deploying the Tucker Trawl.

Using the Tucker Trawl requires a whole team of people. 3 scientists deploy the net, and the captain operates the winch and A Frame so the net doesn’t hit the deck during the process. The NOAA Corpsman drives the boat so as to maintain alignment and speed. One scientist keeps an eve on the angle of the cable, and communicates with the driver to maintain the proper angle by adjusting speed. After recovering the net, all three samples must be rinsed into a bottle. Too much water pressure can mangle the specimens, so we use a gentle rinse. The bottle is then labeled and treated with fixative to preserve the samples. Then it is stored to later be sent to a lab for identification. I have learned that taking these samples requires a lot of communication, to maintain fidelity to a testable process, utilize equipment wisely, and to ensure safety of all personnel.

A view from above as the Tucker Trawl goes out to sea.

 

Each offshore transect has one Tucker Trawl site. After that we move to another site and take Hoop net, CTD, Niskin, water, phytoplankton samples. I will explain these later. Sampling all of these sites provides data for the scientists to investigate the entire ecosystem. They collect plankton (producers) from shallow and deep water, observe marine mammals and birds (predators) on the surface, and sample the environmental conditions such as ocean temperature, salinity, nutrients, and ocean acidification indicators. These studies inform decisions for managing a sustainable environment for both sea life and humans.

Personal

I want to tell you about the galley. This is the kitchen where we store and prepare our food. We have an oven, stove, microwave, sink and two refrigerators, but everything is compact due to limited space. All of the cabinets and the fridge have latches on them to keep food from flying around when the seas are rough. I have to remind myself to latch the fridge each time I open it. I don’t want to be the person who created a giant smoothie in the kitchen!

 

We eat our meals at the table, which then converts to a bed for sleeping. Every little bit of space is used efficiently here.

 

Did you know?

An albatross is part of the tube-nose family of birds. One of its features is having a tube nose above the nares. Nares are the openings to the nostrils. The birds also have openings at the end of the tubes. This adaptation gives it a keen sense of smell. We saw black-footed albatross, which nests in the Hawaiian Islands, and flies long distances across the ocean to find food in the productive waters of Cordell Bank and Greater Farallones National Marine Sanctuaries. So this albatross has been traveling at sea for a long distance!

 

Animals Seen Today

We spotted a CA sea lion cavorting in the wake of the ship. It looked like it was having so much fun as it leaped and twisted above the waves.

 

I love hearing from you. Keep those comments coming!

Science and Technology Log

It wasn’t until the last day or two of my leg of the research project that we finally started to catch the species the scientists were specifically looking to track and even then there were only a few.

Angela removes an otolith from the sample target species

Here’s Angela dissecting one of our first samples.  If the young captured were either sardines or anchovies, they were massed, length taken, sex determined (including whether or not they were sexually mature, if possible), and their otoliths were removed.

So what the heck are otoliths and why would anyone want to remove them?

Otoliths are small, bony parts of a fish’s earbones.  They help the fish with balance and orientation.  These bones are made of calcium carbonate and similar to the formation of rings on a tree, they grow with a ring-like pattern based on seasonal metabolic rates.  While the fish is growing faster during the warmer summer months, the rings are broader and more translucent.  Then, during the cooler winter months when a fish’s metabolic rate begins to slow down, that part of the ring appears to be more dense or opaque.

Look at the first illustration below that was taken from a 2008 NOAA press release.  On the lower right you see an image of an otolith from a haddock.  Each species has otoliths of a particular size and shape. If you know the region of ocean from which a set of otoliths was obtained, you may be able to determine the species by utilizing one of the many otolith references that can be accessed online, such as found in this memorandum published by NOAA researcher Mark S. Lowry.

 

The enlarged image on the right was taken from the NOAA Images Library.  Here you can see the rings very distinctly.

Extension question for my students:  Using the otolith image on the right, determine how old the fish was at the time of capture.  Not sure how to do this just yet?  Want to test your accuracy?  Read up on what is involved in the study of sclerochronology first. Then test yourself with this otolith aging interactive.  Enjoy!

Once the otoliths have been removed they are wiped clean and placed in a small vial to finish drying out.  The otoliths are cataloged and sent to the lab for evaluation as shown in the photos below.

 

The combination of measurements taken allow those studying the population to look at the demographics of the catch (What % of the population is juvenile?  What % is sexually mature? What is the relationship between % male vs. female?).  This data provides a sampling of the population’s health and viability, which can then be extrapolated to the population as a whole.  This information can then be used to help inform policy with regards to how heavily these populations can be fished without causing damage to the ecosystems of which they are a part.

 

Personal Log – It’s time to go home!

It seemed like we had just gotten started and it was time to go!  Although they had mixed work/sleep schedules, the science team was willing to gather to see me off.

Angela, Dereka, Dawn (TAS), Nick, Amy, Bryan, Sue, Emily

What an amazing learning experience!  My only regret was that we didn’t start to find the species requiring the more intense, time-consuming dissection and data collection until the very end.  I wanted to make sure I was doing my part!  In return, what I get to take home to my students is invaluable. I can’t wait to share all I have learned about life aboard a research vessel, the many ways in which this unique habitat is being studied, and the vast opportunities that await those who are interested in marine ecosystems.

The only travel plan that was not prearranged regarding my TAS adventure was the exact location of my departure from the Reuben Lasker.  What I did know was that it was to be a “wet transfer.”  What I didn’t know was exactly what that meant.  It was so much fun finding out!

The Reuben Lasker has a limited number of ports along the west coast where it is possible for it to dock.  The ship’s size, unique keel, and specialized, below-ship sonar equipment require channels to be much deeper than many smaller ports possess.  Because of this, whenever there is to be an exchange of personnel made before a larger port is reached, an onboard transfer craft brings those getting off to a smaller port along the way.  This allows the main vessel to stay in safer waters much further off shore.  Once the exchange of people and gear is made, the transfer boat returns to the ship and the journey continues.

Unique points to consider on this type of trip, however, are that you need to get the transfer boat launched from the main vessel, the ship lets you off several miles from port, and the boat has no seats – you stand up the whole way!  Who knew that even getting back to the mainland was to be an adventure?!

You can see the transfer boat below (right side in the picture – port side of the ship).  Notice how the Reuben Lasker carries it hoisted up off the floor of the back deck.

View of the transfer boat (at right) stored on Reuben Lasker

The transfer boat gets lowered to deck level so we can all step in.  Our gear is stored in the open bow and we all load in the back.  Behind the center console are poles with handles that give us something stable to hold on to as we will be standing for the duration of the trip.  We all wear life jackets and hard hats as the boat is lowered along-side the main ship.

Here’s Skilled Fisherman Victor Pinones ready at the controls as he lowers us to sea level.

The two outboard motors are started while we are along-side so we are ready to move away from the Reuben Lasker the minute we hit the water.  And we’re off! To give you some perspective of the size of the Reuben Lasker as it looks from the water, you can see Emily, Angela, and Dereka waving to me from the Level-1 deck.

View of NOAA Ship Reuben Lasker from the transfer boat

It didn’t take long before the ship was but a spot on the horizon….

Here’s a better look at the transfer vessel as crew members prepare to for the return trip.

Bon voyage to all!  Safe travels!

Did You Know?

Fun fact: Baby squid are adorable!  Just had to share one last image from under the microscope – thanks, Nick, for pointing this out!  At this larval stage, the squid are mainly transparent except for their developing eyes and chromatophores (sac-like structures filled with pigments that help the squid undergo color changes).  You can observe this process in action at the Smithsonian’s  Ocean Portal web site.

 

Looking at the enlarged photo at right you can just make out the scale – our little friend was a whole 3 mm in diameter!  Too cute!

Science and Technology Log:

One of the first things you learn to do as a teacher is to plan for things to go wrong. When you put a lesson together, you try to identify potential problem areas, and then try to figure out how you could address those problems when they do arise, or try to avoid them altogether. One of the next things that you learn is that the biggest problem is invariably going to be something you never anticipated being a problem at all. Deploying a research buoy, it turns out, works essentially the same way.

Bird Wire

WHOTS stations are massive, self-contained buoys, designed to stay at sea for up to eighteen months, collecting data the entire time. There are redundant systems on top of redundant systems. Multiple meteorological instruments, measuring exactly the same thing, sprout from the buoy’s tower like misshapen mushrooms. If one instrument fails, there is always another — to ensure that, no matter what, the data is collected. And surrounding it all, like the spines of a porcupine, is the bird wire.

Anything that floats on the ocean winds can be a perch for birds, and the WHOTS buoys are no exception. I’ve been told that after a year at sea, the buoy is absolutely disgusting. I’ve seen some of the mess New York City pigeons can create, and I’m willing to bet that what I’m imagining cannot even come close. I’ll find out for myself later this week, when we retrieve the WHOTS buoy that was deployed last year! 

Ick factor aside, birds (and their waste products) pose a real danger to the instruments on the buoy’s tower. If something is pecked or perched on or — use your imagination — otherwise damaged, the instruments may record corrupted data, or no data at all. Which is why there are redundant systems, and why Monday morning was spent making the buoy look like a porcupine. But wait! There’s more! It turns out all bird wire is not created equal. All of the spikes are made of stainless steel, but the spikes can be mounted on different things. Bird wire with a stainless steel base is more effective at repelling birds (because the spikes are closer together)… but the spikes have to be welded into the base, which magnetizes the bird wire. And if this wire is placed the instruments, it can affect their internal compasses and, in turn affect the data the bird wire is intended to protect! Bird wire with a plastic base is less effective (because the spikes are further apart), but much safer for the buoy’s instruments.

<<pictures of the bird wire to come!>>

Cayenne Pepper, Copper and Things Covered in Tape

The tower of the WHOTS buoy isn’t the only thing that is absolutely disgusting after spending a year at sea. Everything that spends the year below the surface of the ocean (which will be described in a post later this week) comes back absolutely disgusting, too. And it’s not as though it can all just be thrown away. Of particular importance are the instruments attached under the buoy and about every 10 meters (down to 150 meters) along the buoy’s mooring line. All of these instruments must be returned to the manufacturer for calibration (to make sure they were working properly). But there’s a catch — they must be returned clean! Which means that everything that has been growing on them while they’ve been under water must be scrubbed, scraped or peeled off. To make the job easier, the search is always on for ways to keep things from growing on the instruments in the first place. This is called antifouling.

One antifouling method is painting. There are specialized antifouling paints available, but they can be toxic. So the paint that covers the exterior of the buoy contains cayenne pepper (!), which has proven to be as effective as specialized paint, but is much safer. Another antifouling method used on many of the instruments under the buoy involves replacing some stainless steel components with specially made copper ones, as copper also naturally impedes growth. And a third method that’s very popular is simply to cover the instruments with a layer of electrical tape, which can just be peeled off — no scrubbing or scraping involved!

<<pictures of the antifouling methods used on the buoy to come!>>

Personal Log:

<<pictures of loading the food to come!>> “You’re lucky you weren’t here when we had to load for three months!”

Throughout the day, refrigerated trucks pulled up on the dock next to the Hi’ialakai. They were not full of delicate scientific instrumentation, but something just as vitally important to the cruise — food! The same crane that had been used to hoist instruments on board was also used to carry pallets of food from the dock to the deck of the ship. Then it was passed from hand to hand (by members of the ship’s crew, the science team, the ship’s officers, and the Teacher at Sea) all the way down to the galley’s refrigerators and freezers. The ice cream was handled with particular care — no surprise there!

Science and Technology Log

One of the major questions I had before my Teacher at Sea voyage was how the level of oxygen in the water will affect the species we collect. Typically, in the summer, a dead zone forms in the Gulf of Mexico spreading out from the mouth of the Mississippi river. You can see an image of the dead zone from 2011 below.

Hypoxia2011

Bottom Dissolved Oxygen Contours, Gulf of Mexico, 2011

Phytoplankton, or microscopic marine algae, are the base of the marine food web. There are two main classes, diatoms and dinoflagellates, which are both photosynthetic and typically live towards the top of the water column. We did not sample plankton on our leg of the cruise, but if you want to learn more you can check out this site: https://oceanservice.noaa.gov/facts/phyto.html. In the summer, phytoplankton and algae can build up due to excess nutrients in the water that are running off from urban areas, agriculture and industry. Much of our sampling was near the mouth of the Mississippi River, which is a significant source of excess nutrients. The extra nitrogen and phosphorus in the runoff cause the excess growth of photosynthetic organisms which leads to a buildup of zooplankton (heterotrophic plankton). Once the phytoplankton and zooplankton die and sink to the bottom they are decomposed by oxygen consuming bacteria which deplete the oxygen in the water column. According to NOAA, hypoxia in aquatic systems refers to an area where the dissolved oxygen concentration is below 2 mg/L. At this point, most organisms become physiologically stressed and cannot survive.

How The Dead Zone Forms: Infographic by Dan Swenson, NOLA.com/The Times-Picayune

Tropical Storm Cindy, which kicked up just as I was arriving in Galveston, brought significant freshwater into the gulf and mixed that water around so we did not see as many low oxygen readings as expected. While I was talking with Andre about hypoxia when we were on the ship, he used the analogy of stirring a bowl of soup. There is a cool layer on top, but as you stir the top layer and mix it with the lower layers, the whole bowl cools. Similarly, the oxygen rich freshwater from the storm is mixed around with the existing water, reducing the areas of low oxygen. You can see in the map below that we had fewer hypoxic areas than in 2011.

2017-hypoxia-contours

We used the CTD to obtain oxygen readings in the water column at each station. In the visuals below you can see a CTD indicating high oxygen levels and a CTD indicating lower, hypoxic, oxygen levels. The low oxygen CTD was from leg one of the survey. It corresponds with the red area in the hypoxia map above.

Final sunset over the Gulf of Mexico

When I arrived back on land I still felt the rocking of the Oregon II. It took two to three days before I felt stable again. As friends and family ask about my experience, I find it hard to put into words. I am so grateful to the NOAA Teacher at Sea program for giving me this incredible experience and especially thankful to Science Field Party Chief Andre Debose and my day shift science team members, Tyler, David and Sarah, for teaching me so much, being patient and making my experience one that I will never forget.

The ocean is so vast and we have explored so little of it, but now, I have a strong understanding of how a large scale marine survey is conducted. Being an active participant in fisheries research was definitely out of my comfort zone. The experience helped stretch me and my learning and has giving me great insight to bring back to share with my students and school community. The map below shows our journey over the two weeks I was on the ship traveling along the Texas, Louisiana, Mississippi and Florida coasts.

The blue line maps our route on the Oregon II

My experience on Oregon II has also re-engaged me with the ocean. As a child, I spent time each summer on an island off the coast of Maine and even got to go fishing with my Dad and his lobsterman buddies. But for the last 20 years or so, my exposure to the ocean has been limited to just a few visits. My curiosity for the marine world has been reignited; I look forward to bringing more fisheries science and insight into my classroom.

I mentioned in a previous blog that our shrimp data was sent daily to SEAMAP and made available to fisheries managers and shrimpers to allow them to make the best decisions about when to re-open the shrimp season. According to Texas Parks and Wildlife (TPWD), the commercial shrimp season for both the state and federal waters re-opened just after sunset on July 15, 2017. TPWD said, “The opening date is based on an evaluation of the biological, social and economic impact to maximize the benefits to the industry and the public.” It is satisfying to know that I was part of the “biological evaluation” to which they refer.

 

Finally, I took some video while out at sea and now with more bandwidth and time, I’ve been able to process some of that video to shed additional light on how fisheries research is conducted. I’ve added two videos. The first one shows the process of conducting a bottom trawl and the second one show the fish sorting and measuring process. Enjoy!

The largest Gulf of Mexico dead zone recorded was in 2002, encompassing 8,497 square miles. The smallest recorded dead zone measured 15 square miles in 1988. The average size of the dead zone from 2010-2015 was about 5,500 square miles, nearly three times the 1,900 square mile goal set by the Hypoxia Task Force in 2001 and reaffirmed in 2008.

Dawson Sixth Grade Queries

Thank you to the Dawson sixth graders (now seventh graders!) for your great questions. I look forward to speaking with you all when school starts in a few weeks.

What is at the bottom of the low oxygen part of the ocean? (Allison)

There is a lot of accumulated dead organic matter that is decomposed by oxygen consuming bacteria.

What do you find in the dead zone? Do less animals live there? (Leeham, Mae, Shane, Alfie, Bennett)

Typically, trawls are smaller and the diversity of organisms decreases in the low oxygen areas. Often you will find resilient organisms like croaker. There is a lot of research looking at which organisms can live in dead zones and how these organisms compensate for the low levels of oxygen.

Is there any way to fix the dead zone? What can we do about the dead zone? (Isaac, Owen, Ava)

It is estimated that seventy percent of the excess nitrogen and phosphorus that runs off into the Gulf of Mexico comes from industrial agriculture. Reducing the amount of fertilizer used to grow our food would help decrease the extent of the dead zone area. Perhaps one of you will come up with a way to feed our communities in a more sustainable way or a technology that can remove these excess nutrients before the water reaches the Gulf.

Thanks for reading my blog!

Scientific Log:

Saturday was my first day out, and it was an excellent day for wildlife observation. In fact, that is what I did for most of the day. A highlight of my day was seeing two blue whales spouting right in front of the Fulmar. I tried to get a photo, but they went below the surface quickly. Blue whales are the largest marine mammals, averaging 20-25meters long and blue grey in color. It is called a cetacean, which means it has flukes, (tail fin), and may or may not have a dorsal fin (the fin on the back or top of the body.) This is in contrast to pinnipeds, which are marine mammals that use their flippers to walk. The blue whale is a baleen whale, which feeds by chasing prey up to the surface of the water. There it forages by swimming with its mouth open to catch small invertebrates such as krill and copepods. The baleen in its mouth filters out the invertebrates from the water.

The whale we saw most often was the humpback whale. This baleen whale averages 11-13 meters in length, and is dark grey to black in color. I was so excited to observe 3 tail flukes of humpbacks today!

Birds seen Saturday:

Common murre – including the first murre chicks of the season the ACCESS crew has sighted.

Many marine animals tend to be found where upwelling occurs. Deep ocean nutrient-filled waters are brought to the surface by changes in sea floor topography, winds and currents. These nutrients fertilize phytoplankton (tiny plant life) that serves as the base of the food web. Whales return to these areas to feed on the small invertebrates that flourish there. These hotspots occur just off the Ca Coast. Protecting and managing these ecosystems is one major reason we have established National Marine Sanctuaries such as The Greater Farallones National Marine Sanctuary, Cordell Bank, and Monterey Bay. In a later post, I’ll tell you more about the procedures the scientists use to observe and record the mammal and bird sightings.

Personal Log:

That’s me, in front of the Fulmar!

I settled into my berth onboard the R/V Fulmar. The ship can sleep 10 people, has a galley (shipspeak for kitchen), a wet lab (place to conduct experiments that are wet!) and one head (shipspeak for bathroom). Although the ship is only 67 feet long, the scientist and crew work together so efficiently that it is very comfortable. It has everything we need. I am rooming with Dani Lipski, who is one of the scientists. I’m on the bottom bunk. I’ll introduce her to you later on. She has spent a lot of time teaching me how to use the equipment to take samples. She has graciously answered my millions of questions!

My bunk on the bottom. Do you see the ladder to the escape hatch on the right?

I am delighted to find that I am not feeling seasick. My doctor did prescribe me the patch to wear behind my ear, and I guess it’s working! In any case, I’m not taking it off to test it out. We have had some pretty bumpy experiences transiting to sampling sites and so far so good.I have learned to always keep one hand on the boat when walking around, and not to go below deck when the ship is moving. It surprises me to experience what a workout my legs are getting simply by working to maintain my balance. Even while sitting here writing on my computer I have to constantly engage my legs so I don’t fall over.

Did you know?

The Traffic Separation Scheme (TSS) separates ship traffic going in opposite directions, much like a median strip separates opposing lanes of cars on a freeway. The TSS is marked on nautical charts so that traffic proceeds safely.

I love hearing from you. Keep those comments coming!

Science and Personal Log

I’m putting both the science and personal log together this time around for a very special reason.

See, I have a confession to make.  Many of my friends from home know this about me, but I have a secret I’ve kept under wraps for the vast majority of this trip, and it’s time to officially reveal it now, because it just seems to fit so well.  Ready?  True confessions from a Teacher At Sea:

I have an irrational fear of birds.

There.  I said it.  It stems from a wayward trip to London in the Study Abroad program and involves me, innocently consuming an over-priced deli sandwich on a bench outside of the Museum of Natural History when I was suddenly accosted by a one-footed pigeon who made away with my lunch – but not before attacking my face full-force with every wing, beak, and claw it had.  My lunch then became a free sidewalk hoagie, available for all nearby pigeons (you know, like every pigeon from London to France) to feast upon as I sat helplessly watching the gnashing of beaks and flyings of feathers in a ruthless battle to the end for over-processed deli ham and havarti on rye.  I was mortified.  From that moment forth, I was certain every bird wanted a piece of my soul and I was darned if I was going to let them have it.

After many years of active bird-avoidance, my first Teacher At Sea experience allowed me to remove Puffin from the exhaustive list of these ruthless prehistoric killers.  After all, Puffins are not much more than flying footballs, and generally only consume food of the underwater persuasion, so I felt relatively sheltered from their wrath.  Plus they’re kind of cute.  The following year, a Great Horned Owl met its demise by colliding face-first into one of our tall glass windows at the school. When the Biology teachers brought him inside, I felt oddly curious about this beast who hunts with stunning accuracy in the black of night, and yet couldn’t manage to drive himself around a window.  I felt myself incongruously empathetic at the sight of him – he was such a majestic creature, his lifeless body frozen in time from the moment he met his untimely ending.   I couldn’t help but wish him alive again; if not for his ability to hunt rodents, but simply because nothing that beautiful should have to meet its maker in such a ridiculous manner.  And so, I cautiously removed Owls from the list, so long as I didn’t have to look much at their claws.

This has suited me well over the years – fear all birds except for Puffin and Owl, and as a side note Penguin, too, since they can’t do much damage without being able to fly and all.  Plus, you know, Antarctica.  But when I found out that the cetacean study also happened to have bird observers on the trip, I felt momentarily paralyzed by the whole ordeal.  I had (incorrectly) assumed that we wouldn’t see birds on this trip.  I mean, what kind of bird makes its way to the middle of the Pacific Ocean?  Well, it turns out there are a lot that do, and it’s birders Dawn and Chris who are responsible for sighting and cataloging them alongside the efforts of the marine mammal observers.  I promise I’ll come back to my story on bird fear, but for now, let’s take a look at how our birders do their job.

DES_4224

NOAA bird observer Dawn scans the horizon from her seat on the flying bridge

The birders follow a similar protocol to the marine mammal observers.  Each birder takes a two-hour shift in a front seat on the flying bridge.  While the marine mammal observers use big eyes to see out as far as they possibly can out onto the horizon, the birders only watch and catalog birds that come within 300m of the ship.

DES_4623

You can find the distance a bird is from the ship using a basic pencil with lines marked on the side. Each line is mathematically calculated using your height, the ship’s height, and the distance to the horizon.

How do they know how far away the 300m mark is?  Over the years they just become great visual judges of the distance, but they also have a handy “range finder” that they use.  The range finder is just a plain, unsharpened pencil with marks ticked off at 100m intervals.  By holding the pencil up to the horizon and looking past it, they can easily find the distance the bird is from the ship. They divide this 300m range into “zones” – the 200-300m zone, the 100-200m zone, and the less than 100m zone from the bow of the ship.  Anything further than 300m or outside of the zero to 90 degree field of vision can still be catalogued if it is an uncommon species, or a flock of birds.  (More on flocks in a moment.)

They choose which side of the ship has the best visibility, either the port or starboard side, and like the mammal observers, birders take only the directional space from zero (directly in front of the ship) to 90 degrees on the side of their choosing.  If the visibility switches in quality from one side to the other during a shift, he or she can change sides without issue.

DES_4579

A sooty tern soars high above the ship. We’ve seen many sooty terns this trip!

The bird team also records information such as wind speed and direction (with respect to the ship), the Beaufort Sea State, visibility, observation conditions, and the ship’s course.  Observation conditions are a critical component of the birder’s tool bag.  They mark the observation conditions on a five-point scale, with 1 being extremely bad conditions and 5 being very good conditions.  What defines good conditions for a birder? The best way to make an observation about the conditions is to think about what size and species of smaller birds an observer might not be able to see in the outermost range. Therefore, the condition is based on species and distance from the ship.  Some birds are larger than others, and could be easier to spot farther out from the ship.  The smallest birds (like petrels) might not be observable in even slightly less than ideal conditions. Therefore, if a birder records that the conditions are not favorable for small birds at a distance of 200m (in other words, they wouldn’t be able to see a small bird 200m away), the data processing team can vary the density estimates for smaller birds when observers are in poor visibility.

DES_4568

White terns look like they belong on holiday cards! A new favorite of mine.

If a bird flies into the designated “zone”, the species is identified and recorded on a computer program that will place a time stamp on the GPS location of the sighting. These data are stored on the ship for review at a later time.  Ever wonder where the maps of migration patterns for birds originate?  It is from this collected data.  Up until this point, I had always taken most of these kinds of maps for granted, never thinking that in order to figure out where a particular animal lives let alone its migratory pattern must come from someone actually going out and observing those animals in those particular areas.

DES_4703

An albatross glides behind the ship, looking for fish.

The birder will record other information about the bird sighting like age, sex (if able to identify by sight) and what the lil’ fella or gal is up to when observed.  Birds on the open ocean do a lot more than just fly, and their behaviors are important to document for studies on bird behavior.  There are 9 different codes for these behaviors, ranging from things like directional flight (think, it has a place to go and it’s trying to get there), sitting on the water, or “ship attracted.”  There are certain species like juvenile Red-Footed and Brown boobies and Tropic Birds that are known to be “ship attracted.”  In other words, it could be out flying along a particular path until it sees this super cool giant white thing floating on the water, and decides to go and check it out.  This is how I wound up with that fun photo of the Booby on the bridge wing, and the other snapshot of the juvenile that hung out on the jackstaff for two full days.  These birds would not normally have otherwise come into the range to be detected and recorded, so their density estimates can be skewed if they are counted the same way as all other birds.

DES_4491

This Brown Booby wants in on the food action near the ship. Boobies are ship attracted, and we’ve had a few hang out with us while they take a rest on the mast. This is not the exact booby that made me change my bird ways, but he’s a close cousin (at least genetically speaking) of the one who did.

Any groups of five or more birds within one “reticle” (a measuring tool on the glass of the big eyes seen when looking through them) can be flagged by the marine mammal observers for the birders.  While many flocks are found miles away and might be difficult to see in the big eyes by species, the birders know the flight and feeding behaviors of the birds, and can usually identify the different species within the flock. They have a special designation in their computer program to catalog flocks and their behavior, as well.

I sat with Dawn on a few different occasions to learn how she quickly identifies and catalogs each bird species.  At first, it seems like all the birds look fairly similar, but after a few hours of identification practice, I can’t imagine that any of them look the same. The first bird Dawn taught me to identify was a Wedge-Tailed White Shearwater, more affectionately known as a “Wedgie White.”  To me, they were much more easily characterized by behavior than anything else.  Shearwaters are called “Shearwaters” because they…you guessed it… shear the water!  They are easy to spot as they glide effortlessly just above the water’s surface, almost dipping their wings in the cool blue Pacific.

I then continued my bird observation rotation learning all kinds of fun facts about common sea birds – how plumages change as different species grow, identifying characteristics (which I’m still trying to sort out because there are so many!), stories of how the birds got their names, migration patterns, population densities, breeding grounds, and what species we could expect to see as we approached different islands on the Northwest Hawaiian Island Chain.  Dawn knows countless identifiers when it comes to birds, and if she can’t describe it exactly the way she wants to, she has multiple books with photos, drawings, and paragraphs of information cataloging the time the bird is born to every iteration of its markings and behaviors as it grows.  To be a birder means having an astounding bank of knowledge to tap into as they have a limited time to spot and properly identify many species before they continue on their journey across the Pacific.

DES_4517

This Great Frigate Bird was flying about fifteen feet overhead, with a mast directly in front of him as he flew. He’s looking around for birds to steal food from. The Hawaiian term for Frigate Bird is ‘Iwa, meaning “thief.”

After two weeks of watching for birds with Dawn and Chris, I feel like I can properly identify a few different species – Wedgies, Frigate Birds (these are the klepto-parasite birds that steal other birds’ dinners), Tropic Birds, two types of Terns, and boobies, though I can only best ID boobies when they are not in flight.  I find myself up on the flying bridge on independent observation rotations calling forward to the birder on rotation, “Was that a tern?”  And now, my identifying skills have vastly improved over the last few days as I have engaged in the process of this very important data collection.

So, what has become of my irrational bird fear?  Well, I have to be honest; much like Puffin and Owl, the Red-Footed Booby melted my heart.  There he was, perched on the bridge’s shade railing, a lonely little fellow staring up at me with no reservation about my presence or expectation of a sandwich.  There we were in the middle of a vast ocean, and he was all alone – simply looking for a place to rest his wings or search more earnestly for the hint of a delicious flying fish escaping the water.  I spent a fair amount of time photographing the little guy, working with my new camera to find some fun angles and depth of field, and playing with the lighting.  He was a willing and I daresay friendly participant in the whole process (in fact I wondered if he had seen a few episodes of America’s Next Top Model), and I felt myself softening my stance on placing the Red Footed Booby amongst the likes of attack pigeons.  By the end of our encounter, I had mentally noted that the Booby should now be placed on the “safe bird” list.

As I’ve spent more time with Dawn and Chris and learned more about each species, seabirds have one by one slowly migrated over to the safe list – to the point now where there are just too many to recite and I feel it is time after fifteen years to do away with the whole of it entirely.  As soon as I changed my perspective, the beauty of all of them have gradually emerged to the point where I can easily find something to appreciate (even admire) about each of the species we’ve seen.  Terns fight fiercely into the wind as they fly, but when they can catch a thermal or pose for an on-land photograph for an ID book, look dainty and regal in their appearance – as if they should be a staple part of every holiday display.  And baby Terns?  Doc (our Medical Doctor on board) showed me a photo of a tern chick that followed him around Midway Island last year and the lil’ guy was so darn cute it could make you cry glitter tears.  Today near French Frigate Shoals many of the species I’ve seen from afar came right up to the ship and glided effortlessly overhead, allowing me to observe them from a near perspective as they flew.  (None of them pooped on me, so if they weren’t off the list by that point, that act of grace alone should have sealed their fate for the positive.)  Frigate Birds can preen their feathers while they fly.  Watching each species cast their wings once and glide on the air while looking all around themselves was oddly entertaining, certainly peculiar, but also impressive.  I can’t walk on the ship looking anywhere besides exactly where I want to go and yet birds can fly five feet away from a mast and casually have a proper look about.

If this has taught me anything, it has shown me the truth in the statement that fear is just ignorance in disguise.  When I accidentally gave my bird aversion away during our quick stop at French Frigate Shoals (more on this in an upcoming blog post) many of the scientists said, “I’d have never guessed you were scared of birds.  How did you keep it secret?”  The easy answer is “Teacher Game Face.” But, more deeply rooted in that is a respect and admiration for those who enjoy the things that I’m afraid of.  Dawn and Chris have dedicated their entire careers to identifying and cataloging these creatures, and they are both so kind and respectable I find it hard to imagine that they would study anything unequal to the vast extent of their character.  Thankfully I learned this early enough on in the trip that it was easy to trust their judgement when it comes to Procellariiformes.   This experience is once-in-a-lifetime, and how short-sighted would I be to not want to explore every aspect of what goes on during this study because I’m a little (a lot) afraid?

In Colorado, before I ever left, I made a personal commitment to have a little chutzpah and learn what I can about the distant oceanic cousins of the sandwich thieves.  And when it came to that commitment, it meant genuinely digging in to learn as much as I can, not just pretend digging in to learn at little.  I figured if nothing else, simple repeated exposure in short bursts would be enough for me to neurolinguistically reprogram my way into bird world, and as it turns out, I didn’t even really need that.  I just needed to open up my eyes a little and learn it in to appreciation.  Learning from Dawn and Chris, who are both so emphatically enthusiastic about all things ornithology made me curious once again about these little beasts, who over the last two weeks have slowly transformed into beauties.

Sorry, pigeons.  You’re still on the list.

Science and Technology Log:

As promised in Blog Post #3, I mentioned that “Thing number four we deliberately throw overboard” would have a dedicated blog post because it was so involved.  Well, grab some popcorn, because the time has arrived!

Thing number 4 we deliberately throw over the side of a ship does not get thrown overboard very often, but when it does, it causes much hubbub and hullaballoo on the ship.  I had the unique opportunity to witness one of only ten ocean noise sensors that are deployed in US waters come aboard the ship and get redeployed.  These sensors are found all over US waters – from Alaska to the Atlantic.  One is located in the Catalina Marine Sanctuary, and still others are hanging out in the Gulf of Mexico, and we are going to be sailing right past one!  To see more about the Ocean Noise Sensors, visit the HICEAS website “other projects” tab, or just click here.  To see where the Ocean Noise Recorders are, click here.

The Ocean Noise Sensor system is a group of 10 microphones placed in the “SOFAR” channel all over US waters.  Once deployed, they collect data for two years in order to track the level of ocean noise over time.  It’s no secret that our oceans are getting louder.  Shipping routes, oil and gas exploration, and even natural sources of noise like earthquakes all contribute to the underwater noise that our cetacean friends must chatter through.  Imagine sitting at far ends of the table at a dinner party with a friend you have not caught up with in a while.  While other guests chat away, you and the friend must raise your voices slightly to remain in contact.  As the night progresses on, plates start clanging, glasses are clinking, servers are asking questions, and music is playing in the background.  The frustration of trying to communicate over the din is tolerable, but not insurmountable.  Now imagine the host turning on the Super Bowl at full volume for entertainment.  Now the noise in the room is incorrigible, and you and your friend have lost all hope of even hearing a simple greeting, let alone have a conversation.  In fact, you can hardly get anyone’s attention to get them to pass you the potatoes.  This is similar to the noise levels in our world’s ocean.  As time goes on, more noise is being added to the system.  This could potentially interfere with multiple species and their communications abilities.  Calling out to find a mate, forage for food, or simply find a group to associate with must now be done in the equivalent din of a ticker-tape parade, complete with bands, floats, and fire engines blaring their horns.  This is what the Ocean Noise Sensor is hoping to get a handle on.   By placing sensors in the ocean to passively collect ambient noise, we can answer two important questions:  How have the noise levels changed over time?  To what extent are these changes in noise levels impacting marine life?   

Many smaller isolated studies have been done on ocean noise levels in the past, but a few years ago, scientists from Cornell partnered with NOAA and the Pacific Islands Fisheries Science Center (PIFSC) and the Pacific Marine Environmental Lab to streamline this study in order to get a unified, global data source of ocean noise levels.  The Pacific Marine Environmental Lab built a unified sound recording system for all groups involved in the study, and undertook the deployments of the hydrophones.  They also took on the task of processing the data once it is recovered.  The HICEAS team is in a timely and geographical position to assist in recovery of the data box and redeploying the hydrophone.   This was how we spent the day.

The recovery and re-deployment of the buoy started just before dawn, and ended just before dinner.

 Our standard effort of marine mammal observation was put on hold so that we could recover and re-deploy the hydrophone.  It was an exciting day for a few reasons – one, it was definitely a novel way to spend the day.  There was much to do on the part of the crew, and much to watch on the part of those who didn’t have the know-how to assist.  (This was the category I fell in to.)

At dawn, an underwater acoustic command was sent to the depths to release a buoy held underwater attached to the hydrophone.  While the hydrophone is only 1000m below the surface seated nice and squarely in the SOFAR channel, the entire system is anchored to the ocean floor at a depth of 4000m.  Once the buoy was released, crew members stationed themselves around the ship on the Big Eyes and with binoculars to watch for the buoy to surface.  It took approximately 45 minutes before the buoy was spotted just off our port side.  The sighting award goes to CDR Stephanie Koes, our fearless CO.  A crewmember pointed out the advancement in our technologies in the following way:  “We can use GPS to find a buried hydrophone in the middle of the ocean…and then send a signal…down 4000m…to a buoy anchored to the ocean floor…cut the buoy loose remotely, and then actually have the buoy come up to the surface near enough to the ship where we can find it.”  Pretty impressive if you think about it.

The buoy was tied to the line that is attached to the hydrophone, so once the buoy surfaced, “all” we had to do was send a fast rescue boat out to retrieve it, bring the buoy and line back to the ship, bring the crew safely back aboard the ship, hook the line up through a pulley overhead and back to a deck wench, pull the line through, take off the hydrophone, pull the rest of the line up, unspool the line on the wench to re-set the line, re-spool the winch, and then reverse the whole process.

Watching the crew work on this process was impressive at least, and a fully orchestrated symphony at best.  There were many tyings of knots and transfers of lines, and all crew members worked like the well-seasoned deck crew that they are.  Chief Bos’n Chris Kaanaana is no stranger to hauling in and maintaining buoys, so his deck crew were well prepared to take on this monumental task.

Much of the day went exactly according to plan.  The buoy was safely retrieved, the hydrophone brought on board, the lines pulled in, re-spooled, and all sent back out again.  But I am here to tell you that 4000m of line to haul in and pay back out takes. A Long. Time.  We worked through a rainstorm spooling the line off the winch to reset it, through the glare of the tropical sun and the gentle and steadfast breeze of the trade winds.  By dinner time, all was back in place, the buoy safely submerged deep in the ocean waters, waiting to be released again in another two years to repeat the process all over again.  With any luck, the noise levels in the ocean will have improved.  Many commercial vessels have committed to adopting “quiet ship” technology to assist in the reduction of noise levels.  If this continues to improve, our cetacean friends just might be able to hear one another again at dinner.

 

Personal Log

So, I guess it’s pretty fair to say that once you’re a teacher, you’re always a teacher.  I could not fully escape my August to May duties onboard, despite my best efforts.  This week, I found myself on the bridge, doing a science experiment with the Wardroom (These are what all of the officers onboard as a group are called).   How is this even happening, you ask?  (Trust me, I asked myself the same thing when I was in the middle of it, running around to different “lab groups” just like in class.)  Our CO, CDR Koes, is committed to ensuring that her crew is always learning on the ship.

 If her staff do not know the answer to a question, she will guide them through the process of seeking out the correct answer so that all  officers learn as much as they can when it comes to being underway –  steering the ship, preparing for emergencies, and working with engineers, scientists, and crew.  For example, I found out that while I was off “small-boating” near Pilot Whales, the Wardroom was busy working on maneuvering the ship in practice of man overboard scenarios.  She is committed to ensuring that all of her staff knows all parts of this moving city, or at a minimum know how to find the answers to any questions they may have.  It’s become clear just how much the crew and the entire ship have a deep respect and admiration for CDR Koes.  I knew she was going to be great when we were at training and word got out that she would be the CO of this Leg on Sette and everyone had a range of positive emotions from elated to relieved to ecstatic.

As part of this training, she gives regular “quizzes” to her staff each day – many of them in good fun with questions for scientists, crew, engineers, and I.  Some questions are nautical “things” that the Wardroom should know or are nice to know (for example, knowing the locations of Material Safety Data Sheets or calculating dew point temperatures), some questions are about the scientific work done onboard, while others are questions about personal lives of onboard members.

The Chief Medical Officer, “Doc” gives a lesson on water quality testing.

 It has been a lot of fun watching the Wardroom and Crew seek out others and ask them where they live while showing them their “whale dance” to encourage sightings.  It has exponentially increased the interactions between everyone onboard in a positive and productive way.

The other teaching element that CDR Koes has implemented is a daily lesson each day from Monday to Friday just after lunch.  All NOAA Officers meet on the bridge, while one officer takes the lead to teach a quick, fifteen minute lesson on any topic of their choosing.  It could be to refresh scientific knowledge, general ship operations, nautical concepts, or anything else that would be considered “good to know.”

 This sharing of knowledge builds trust among the Wardroom because it honors each officer’s strong suits and reminds us that we all have something to contribute while onboard.

I started attending these lunchtime sessions and volunteered to take on a lesson.  So, this past Tuesday, I rounded up some supplies and did what I know best – we all participated in the Cloud in a Bottle Lesson!

Here I am learning to use a sextant for navigation.

The Wardroom had fun (I think?) making bottle clouds, talking about the three conditions for cloud formation, and refreshing their memories on adiabatic heating and cooling.  It was a little nerve wracking for me as a teacher because two of the officers are meteorologists by trade, but I think I passed the bar.  (I hope I did!)

It was fun to slide back into the role of teacher, if only for a brief while, and served as a reminder that I’m on my way back to work in a few weeks!  Thanks to the Wardroom  for calling on me to dust up my teacher skills for the upcoming first weeks of school!

Facebook Asks, DeSchryver Answers

I polled all of my Facebook friends, fishing (ha ha, see what I did there?) for questions about the ship, and here are some of the questions and my answers!

 

Q:   LC asks, “What has been your most exciting moment on the ship?”

It’s hard to pick just one, so I’ll tell you the times I was held at a little tear:  a) Any sighting of a new species is a solid winner, especially the rare ones  b) The first time I heard Sperm Whales on the acoustic detector c) The first time we took the small boat out for UAS operations….annnndddd d) The first time I was on Independent Observation and we had a sighting!

Q:  JK asks, “What are your thoughts on the breakoff of Larsen C?  And have there been any effects from the Alaskan quake and tsunami?”

We’re actually pretty isolated on board!  Limited internet makes it hard to hear of all the current events.  I had only briefly heard about Larsen C, and just that it broke, not anything else.  I had no clue there was a quake and tsunami!  But!  I will tell a cool sort of related story.  On Ford Island, right where Sette is docked, the parking lot is holding three pretty banged up boats.  If you look closely, they all have Japanese markings on them.  Turns out they washed up on Oahu after the Japan Tsunami.  They tracked down the owners, and they came out to confirm those boats were theirs, but left them with NOAA as a donation.  So?  There’s tsunami debris on Oahu and I saw it.

 

Q:  NG asks, “Any aha moments when it comes to being on the ocean?  And anything to bring back to Earth Science class?”

So many aha moments, but one in particular that comes to mind is just how difficult it is to spot cetaceans and how talented the marine mammal observers are! They can quite literally spot animals from miles away!  There are a lot of measures put in place to help the marine mammal observers, but at the end of the day, there are some species that are just tougher than nails to spot, or to spot and keep an eye on since their behaviors are all so different.  And as far as anything to bring back to our class?  Tons.  I got a cool trick to make a range finder using a pencil.  I think we should use it!

 

Q:  MJB asks, “Have you had some peaceful moments to process and just take it all in?”

Yes.  At night between the sonobuoy launches, I get two miles of transit time out on the back deck to just absorb the day and be thankful for the opportunities.  The area of Hawai’i we are in right now is considered sacred ground, so it’s very powerful to just be here and be here.

Q:  SC asks, “What souvenir are you bringing me?”

Well, we saw a glass fishing float, and we tried to catch it for you, but it got away.

Q:  LC asks, “What’s the most disgusting ocean creature?”

Boy that’s a loaded question because I guarantee if I name a creature, someone out there studies it for a living.  But! I will tell you the most delicious ocean creature.  That would be Ono.  In sashimi form.  Also, there is a bird called a Great Frigate bird – it feeds via something called Klepto-parasitism, which is exactly how it sounds.  It basically finds other birds, harasses them until they give up whatever they just caught or in some cases until it pukes, and then it steals their food.  So, yeah.  I’d say that’s pretty gross.  But everyone’s gotta eat, right?

Q:  KI asks, “Have you eaten all that ginger?”

I’m about two weeks in and I’m pretty sure I’ve eaten about a pound. I’m still working on it!

Q:  HC asks, ”Have you seen or heard any species outside of their normal ocean territory?”

Sort of.  Yesterday we saw Orca!  They are tropical Orca, so they are found in this area, but they aren’t very common.  The scientific team was thinking we’d maybe see one or two out of the entire seven legs of the trip, and we saw some yesterday!  (I can’t say how many, and you’ll find out why in an upcoming post.)  We have also seen a little bird that wasn’t really technically out of his territory, but the poor fella sure was a little far from home.

Q:  JPK asks, “What kinds of data have you accumulated to use in a cross-curricular experience for math?”

We can do abundance estimates with a reasonably simplified equation.  It’s pretty neat how we can take everything that we see from this study, and use those numbers to extrapolate how many of each species is estimated to be “out there.”

Q: AP asks, “What has surprised you about this trip?”

Many, many things, but I’ll mention a couple fun ones.  The ship has an enormous movie collection – even of movies that aren’t out on DVD yet because they get them ahead of time!  Also? The food on the ship is amazing.  We’re halfway through the trip and the lettuce is still green.  I have to find out the chef’s secret!  And the desserts are to die for.  It’s a wonder I haven’t put on twenty pounds.  The crew does a lot of little things to celebrate and keep morale up, like birthday parties, and music at dinner, and shave ice once a week.  Lots of people take turns barbecuing and cooking traditional foods and desserts special to them from home and they share with everyone.  They are always in really high spirits and don’t let morale drop to begin with, so it’s always fun.

Q:  TS asks, “What’s the most exciting thing you’ve done?”

I’ve done lots of exciting things, but the one thing that comes to mind is launching on the small boat to go take photos of the pilot whales.  Such a cool experience, and I hope we get good enough weather to do it again while we’re out here!  Everything about ship life is brand new to me, so I like to help out as much as I can.  Any time someone says, “Will you help with this?” I get excited, because I  know I’m about to learn something new and also lend a hand.
