Science and Technology Log:

So, as my time on the Oregon II is winding down, I thought I’d share a bit about what it is like to do science on a boat.  First of all, there is a tremendous amount of planning that must go into a successful survey in the weeks and months beforehand.  In addition to all the logistics of going to sea for two weeks, there is the challenge of putting together a crew of scientists that can be away from their day to day jobs and lives, and agree to work 12 hour days, for weeks on end.  Lisa Jones is the Field Party Chief for this survey and must figure out those logistics plus organize the science part as well.  This survey has been going since 1995, and one of the keys to longitudinal data sets is that they keep standard methods throughout, or else the data aren’t comparable.

This can be challenging in all sorts of unforeseen ways.  For example, a few years ago, it became difficult to find the mackerel used as bait on the longlines.  During an experimental survey in the spring, they tried out squid as an alternative and caught a totally different composition of species.  Fortunately, the mackerel became more available again, and the problem is no longer an issue, for now.

Lisa is also the one responsible for working with the captain and his crew to determine sampling locations and a plan for getting to those locations.  There’s a plan at the beginning, but, of course, that changes frequently, due to weather, the locations of other ships and a myriad of other unforeseen circumstances.  The goal is to reach 200 sites per year, with 50% between 5-30 fathoms (1 fathom=6 feet), 40% between 30-100 fathoms, and 10% between 100-200 fathoms.  These percentages reflect the depths of the continental shelf area throughout the sampling region. Below is a sampling map for the 2015 longline survey.

During a longline set, the line is deployed for one hour before retrieval, with 100 baited hooks.  As the line comes in, each fish is given three to four measurements (depending on the species) and is weighed.  Many of the sharks are tagged, as this provides the possibility of someone finding the tagged shark in the future.  With a tag retrieval, we can learn about how far the organism has traveled and how much and how quickly it has grown.

As I mentioned in my post about the red snappers, the snappers, groupers and tilefish are dissected for their otoliths and gonads.  They can’t be successfully released in most circumstances anyway, due to barotrauma from pulling them quickly to the surface from depth.

Sharks are less affected by barotrauma because they don’t have swim bladders to maintain their buoyancy like the bony fishes we’ve been catching.

Here are a couple examples of our data sheets.  As you can see, some sets have more fish than others (in fact the full one, was only one of three pages).  Once all the data are collected, they have to be entered in the computer for later summary and analysis.  Some days it can be a big challenge to get all the data entered before it’s time to start all over again.  Other days, like today, include lots of travel time.

For me, it has been truly wonderful to get to work as a scientist again, if just for a couple of weeks, especially with such an amazing group of scientists.  I’ve learned so much from my fellow day crew members (Lisa, Christian, Nick and Jason).  They have patiently answered all my questions, even when it was keeping them from getting to dinner.  Lisa Jones has gone above and beyond in her support of me, even though she has had many other responsibilities on her plate.  I also appreciate being made to feel welcome lurking around the night crew’s catches.  Thanks especially to Christophe, Vaden, and Eric for allowing me to hang out in the measuring pit.  I love my job as a teacher, but part of me definitely misses working as a field biologist.  I am grateful for the opportunity and especially thankful for my wonderful family.  I can’t tell you how much I appreciate your support and love.

Science and Technology Log:

As described in the last blog post, fisheries are regulated by different management councils that represent particular regions of the country.  Of all the different regions, the Gulf of Mexico arguably has the most distinct boundaries of the eight different management councils.  If you look at the Google satellite image below, there are likely a couple of things that jump out at you.  First is that the gulf is almost completely surrounded by land.  It’s less than 100 miles from Florida to Cuba and only about 120 miles at the closest point between Cuba and the Yucatan Peninsula.  This means that there is a lot of potential for the land surrounding the gulf to impact the neighboring waters.

GoogleMapGulfofMexico

Google map satellite image of the Gulf of Mexico

This and the fact that there are some major rivers flowing into the gulf contribute to the formation of what is known as the dead zone.  The dead zone extends along the coasts of Louisiana and Texas, and is caused by extreme nutrient levels in the waters of the Mississippi River.  The Mississippi contains vast quantities of nutrients from agricultural and urban runoff and so contributes abnormally high amounts of nitrogen and phosphorus to the coastal waters.   These nutrients lead to massive algal blooms that create decaying biomass that then deplete the oxygen in the waters where the blooms occur.  The map below was created by data collected on the Oregon II and shows the extent of the dead zone in 2011, so called because many organisms cannot survive in such low oxygen conditions.  The orange and red areas are regions where shrimp and fish cannot live on the sea floor.

Dead_Zone_NASA_NOAA

Dissolved oxygen levels measured during the Oregon II groundfish survey in 2011.  The orange and red areas indicate dissolved oxygen levels on the sea floor below 3 mg/L.

The other noticeable feature of the Gulf as a whole is that there is a lot of shallow water, with the continental shelf extending up to around 200 miles offshore in some areas.  It is especially thick along the coasts of Florida and the Yucatan.  These shallow areas, help to create warm water temperatures, and this helps to provide the energy for hurricanes.  The relatively shallow waters have been a factor in the development of offshore oil drilling, and we’ve passed scores of them along the way.

Some of the oil rig platforms we’ve passed on our trip

The NOAA map below gives a better idea of how abundant the rigs really are.  The construction of these rigs creates significant risk, as evidenced by the Deep Water Horizon explosion and subsequent oil spill.  The explosion happened in April 2010 and the spill continued for nearly three months.  NOAA was involved in documenting the impacts of the spill from the earliest days and will be able to use this information to improve containment and cleanup after future spills.

Except where nutrient levels are excessively high because of human influence, the nutrient rich waters of the Gulf support abundant life, and we’ve been experiencing that for sure.  I’m realizing that we’re only seeing a small snapshot of the diversity of habitats that are found in the Gulf.  There are deep water methane seeps, estuaries, coral reefs, and other reef systems that support different organisms and abundant life.  The Gulf is a vital resource that provides healthy fisheries, but it’s also a thriving ecosystem in its own right.  By coming out on a yearly basis, the scientists conducting these surveys can get an idea of how these ecosystems are faring…kind of like a report card, I guess.

Longitude: 94o 50.3’ W

Wind speed 13 knots

Sea wave height 2-3 feet

Temperature Seawater 28.8 o Celsius

Science and Technology Log:

This is a shark and red snapper longline survey, and the sharks tend to steal the stage.  They are bigger (for the most part), more diverse and definitely have more of a reputation.  I have been surprised, however, by how much I’ve been drawn to the snappers.  They are a beautiful color, and tend to come up in groups that are pretty similar in size.

RedSnapper

Red snapper (Lutjanus campechanus) ready to be measured

The Northern Red Snapper (Lutjanus campechanus) is commonly fished in the Gulf of Mexico, both recreationally and commercially.  It turns out that the commercial fishers get 51% of the catch quota and the recreational fishers get 49%.  The methods for dividing up those two basically equal pieces of the pie is different between the commercial and recreational fishers. In addition, the commercial fishing catch is monitored very closely, while the recreational fishing catch numbers are largely unknown.  Plus, the states have their own waters that extend out to different distances, depending on the state, and the federal waters extend from the state water boundary to 200 nautical miles offshore.  So, in other words, managing the fishery is quite complicated.

So, how do all these fishing rules and regulations get established and modified over time?  A law was passed in 1976, called the Magnuson-Stevens Fishery Conservation and Management Act, and one of the key parts of the act established eight regional management councils for regulating fishing in federal waters (more information on the act here: http://www.nmfs.noaa.gov/sfa/laws_policies/msa/).  It also established the 200 nautical mile extension of federal waters from land.  The Gulf of Mexico Fishery Management Council (GMFMC) is responsible for creating Fisheries Management Plans (FMPs) for fisheries within the U.S. federal waters of the Gulf of Mexico, from southern Texas, along Louisiana, Mississippi, and Alabama, and down the west coast of Florida.  This graphic shows the catch limits for red snapper and other species for 2017 set by the GMFMC.  For red snapper, the catch limit is close to 14 million pounds.

2017ACLBLOGGraphic_07-17-1024x663

Annual Catch Limits as set by the Gulf of Mexico Fishery Management Council (http://gulfcouncil.org/fishing-regulations/federal/)

The data that we are collecting helps scientists and policy makers to determine what the annual catch limit for a particular season should be.  For each fish that we bring on board, we measure the fish length and weight, as well as the weight of the gonads.  In addition, we collect their otoliths (ear bones) and samples of the ovaries of females.  These both help managers to estimate the age and size of the population, and future populations as well.

Otoliths are calcium carbonate hardened structures and are present in the part of the inner ear that is responsible for balance.  Humans and other vertebrates have them too, and they can be used to tell the age of the fish.  The otoliths of Lutjanus campechanus are quite large.  There seems to be an overall relationship between the habitat of the fish species and the size of the otolith.  Species like Lutjanus campechanus that live along reefs and rocky structures have much larger otoliths than species like tuna that swim up in the water column.  Flying fish, which we’ve seen a lot of, also have large otoliths, given their body size, probably aiding them in knowing where they are as they glide through the air.

Otoliths

Otoliths taken from one of the red snappers we collected

Well, we have been collecting a lot of data over the past couple of days to help inform these policies in the future!  Each line we’ve pulled in lately has had a dozen or more snappers on it,  and they are a lot of extra work as compared with the sharks, due to all the samples we have to collect once we’re done.  A couple times, we’ve barely finished before it was time to start baiting lines again.

Personal Log:

As I mentioned earlier, I’ve really come to love the red snappers.  Their eyes are the same color as their skin and I’m just awed by their size.  I am used to snappers that I’ve watched on coral reefs, and even the largest species I’ve seen on reefs are nothing compared with these guys.

I’ve also adjusted to the shift in my day, as evidenced by the fact that I’m finishing this up at 1 a.m.  It has been a long time since I’ve been on this kind of late night schedule.  I’m enjoying it, especially because I know when I return to California, I’ll be getting up at 5:30 a.m. again.

 

Did You Know?

That snappers eat a wide variety of different foods, including fish and various types of crustaceans? Here are a couple of items we’ve found in the ones we’ve caught.  Can anyone identify them?  I studied the second group for my Ph.D. dissertation!

Longitude: 75⁰ 59’01.2 W
Temperature: 19⁰ Celsius (67⁰ Fahrenheit)
Winds: 1 mph SSW

In just a matter of days, my world has gone from this

(we often had a crazy amount of jellyfish to sort through to find the year 0 Pollock)

to this….

(my super worms are warming up their races at the scout overnight tomorrow)

It’s also given me a few days to reflect on the incredible experience I had at sea.

Science and Technology Log

Science is a collaborative. Many people do not realize the amount of teamwork that goes into the scientific process. For instance, several of the scientists on board my cruise don’t actually study Pollock. One of the guys studies Salmon, but he was still on the cruise helping out. I think that’s what really struck me. The folks from the NOAA Northwest Fisheries Science Center pull together as a team to make sure that everyone gets the data they need. They all jump on board ships to participate in research cruises even if it’s not their specific study area, and it’s quite likely someone else is in another location doing the same thing for them. At the end of the day, it’s the data that matters and not whose project it is.

Personal Log

Since returning home, the most frequent question I have received is “what was your favorite part?” At first, I didn’t know how to answer this question. To have such an incredible experience crammed into two weeks, makes it difficult to narrow it down. After a few days of reflection, I finally have an answer.

The onboard relationships were my favorite part of my Teacher at Sea cruise. I appreciated that the entire crew took me under their wing, showed me the ropes, and made 12 hour shifts sorting through jellyfish for Pollock fun! This is the only place where I could have the opportunity to work and live with scientists in such close proximity. I was fascinated by each scientist’s story: how they got into their specialty, what their background is, why they feel what they’re doing is important, etc. I learned that 10 pm became the silly hour when the second cup of coffee kicked in along with the dance music. I learned that beyond Pollock research these folks were also rescuers taking in tired birds that fell onto the ship, warming them up, and then releasing them.

When the next person asks “what was your favorite part?” I will be ready with an answer along with a big smile as I remember all the goofy night shifts, the incredible inside look at sea based research, and the wonderful people I met.  Oh, and the views.

Mission: Shark/Red Snapper Longline Survey

Geographic Area of Cruise: Gulf of Mexico

Date: September 21, 2017

 

Weather Data from the Bridge:

Latitude: 27o 15.5’ N

Longitude: 97o 01.3’ W

Haze

Visibility 6 nautical miles

Wind SE 15 knots

Sea wave height 3-4 feet

Sea Temperature: 29.6o Celsius

Note: Just a month ago Hurricane Harvey was bringing 20 foot seas to this area, but today we’re enjoying the 3-4 foot swell.

Science and Technology Log:

Well, we’ve gotten to the fishing grounds, and we’ve gone from waiting to very busy!  We put out the first lines starting at around 8 pm on Tuesday evening.  The process involves first baiting 100 hooks with Atlantic mackerel.  When it’s time for the line to be deployed, first there is a tall buoy with a light and radar beacon (called a high flyer) on it that gets set into the water, attached to the monofilament fishing line.  Then there’s a weight, so the line sinks to the bottom, a series of 50 baited hooks then get clipped onto the line as the monofilament is being fed out.

Those 50 hooks are referred to as a “skate”.  This confused me last night when I was logging our progress on the computer.  I kept thinking that there was going to be some kind of flat, triangular shaped object clipped on to help the line move through the water…not really sure what I was imagining.  Anyway, Lisa Jones, the field party chief and fisheries biologist extraordinaire, has so kindly humored all my questions and explained that skate is just a term for some set unit of baited hooks.  In this case, the unit is 50, and we’ll be deploying two skates each time.

After the first skate comes another weight, the second skate, another weight and then the last high flyer.  Then the line is set loose and we wait.  It’s easy to locate the line again, even at night, because of the radar beacons on the high flyers.

Why are we collecting this data?

As mentioned in my previous post, one of the tasks of NOAA, especially the National Marine Fisheries Service Line Office, is to collect data that will help with effective fisheries management and assist with setting things like catch quotas and so forth.  A catch quota refers to the amount of a particular species that can be harvested in a particular year.  Fisheries management is incredibly complicated, but the basic idea is that you don’t want to use up the resource faster than it is replenishing itself.  In order to know if you are succeeding in this regard, you must go out and take a look at how things are going.  Therefore, the Oregon II goes out each year in the fall and samples roughly 200 sites over about eight weeks.  The precise locations of the sampling sites change each year but are spread out along the SE Atlantic Coast and throughout the U.S. waters in the Gulf of Mexico.

We’ve put out three long lines so far.  Last night, we caught a single fish, but it was a really cool one.  It’s called the Golden Tilefish but has an even better species name: Lopholatilus chamealeonticeps.  As Lisa was explaining that they dig burrows in the sea floor, I realized that I had seen their cousins while snorkeling around coral reefs but would never have made the connection that they were related. This guy was big!

This afternoon, things got really hectic.  Of our 100 hooks, 67 had a fish on it, and 60 of those were sharks.  As we were pulling in the last bit of line, we pull on a shark that was missing its back half!  Another had a bite taken out of it.  And then on hook number 100, was a bull shark.  This shark had been snacking along the line and got caught in the process.

And I haven’t even mentioned the red snappers.  I will save them for another post, but they are absolutely beautiful creatures.

Personal Log:

I definitely continue to feel out of my element at times, especially as we were pulling in all these hooks with sharks on them, and I could barely keep up with my little job of tracking when a fish came on the boat.  All the sharks started running together in my mind, and it was definitely a bit stressful.  Overall, I feel like I’ve adjusted to the cadence of the boat rocking and have been sleeping a lot more soundly.  I continue to marvel at how amazing it is that we’re relatively close to shore but, except for a few songbirds desperate for a rest, there is no evidence of land that my untrained eyes can detect.  Lastly, I’ve realized that a 12-hour sampling shift is long.  I have a lot of respect for the scientists and crew that do this for months on end each year with just a few days break every now and then. Well, it time to pull in another line.  Next time, we’ll talk snapper.

Personal Log

And just like that, it’s over.  I am back in Flagstaff and have finally stopped feeling the boat rocking while on solid ground.  Students have been working on a shark project in my absence and we are finishing it up this week.  My first day back was a day of show and tell. The students were excited and full of questions about my trip. As I presented to my students, I realized how much I learned and how much more I still want to know! Here are some pictures from Monday.

 

 

 

 

As I reflect back on my adventure, I have many thoughts and wonder how the fourth and final leg is going.  I think back to last year when I first learned I was selected to be on this adventure and how impossible it was to imagine that I was actually going to work with sharks.  Then, as the date loomed closer, trying to best prepare for something that was a big unknown to me.  And then I was at the dock looking at the Oregon II tied up for the weekend. I recall when I first reached the dock in the evening looking at the ship and thinking wow, pinch me, this is really happening.  I remember being awed and out of my element those first few days just learning to navigate the ship. And then the first haul in!  Now that was a rush as we pulled in not only small sharpnose sharks but larger sandbar sharks that needed to be cradled.  It was unbelievable watching as the team worked and I was thrust into being a viable team member.  After a week, it was a game I had to see if I could bait the hooks as fast as the veteran scientists. I automatically logged the fin clips and helped enter the data we had collected.  Working on the ship became the new normal — knowing what to to do at each station’s deployment of the line and the haul back.  I was feeling competent in my role. Even pulling in some sharks became routine…routine!  Wow, had I come a long way.  And then, just like that, I was on my last haul back and heading back into port.

 

Here are some of my favorite videos and photos from the adventure.

Below a time lapse of what a haul back at night looks like

And a video of my favorite shark- the great hammerhead being released out of the cradle.

 

And a baby hammy

 

So here I am, back in Flagstaff, reflecting back on my adventure. Did it really happen?  I have pictures to prove it and stories I am sharing but it does seem like a lifetime ago that I was touching a shark and looking into the doe eyes of a ten foot hammerhead shark.  The more I talk about what I have done, the more I realize how much I learned and how much more I still don’t know.  The two weeks flew by but I am grateful for it. So for those of you out there reading this blog, make time for adventures, get out there and do it, follow your passion and immerse yourself. You might be surprised at what you can do!

Here I am, three weeks deep in a new school year, and it’s hard to believe that less than a month ago I was spotting whales while on marine mammal watch and laughing at dolphins that were jumping in our wake. I feel like telling my students, “I had a really weird dream this summer where I was a marine biologist and did all kinds of crazy science stuff.”

IMG_20170817_103950017_HDR

Me on marine mammal watch

If it was a dream, it certainly was a good one! Well, except for the part when I was seasick. That was a bit more of a nightmare, but let’s not talk about that again. It all turned out okay, right?

I didn’t know what to expect when signing on with the Teacher at Sea program, and I’m amazed at how much I learned in such a short period of time. First of all, I learned a lot about marine science. I learned how to differentiate between different types of jellyfish, I learned what a pyrosome is and why they’re so intriguing, I learned that phytoplankton are way cooler than I thought they were, and I can now spot a hake in any mess of fish (and dissect them faster than almost anyone reading this).

I also learned a lot about ship life. I learned how to ride an exercise bike while also rocking side to side.  I learned that Joao makes the best salsa known to mankind. I learned that everything – everything – needs to be secured or it’s going to roll around at night and annoy you to pieces. I even learned how to walk down a hallway in rocky seas without bumping into walls like a pinball.

Well, okay. I never really mastered that one. But I learned the other things!

Beyond the science and life aboard a ship, I met some of the coolest people. Julia, our chief scientist, was a great example of what good leadership looks like. She challenged us, looked out for each of us, and always cheered us on. I’m excited to take what I learned from her back to the classroom. Tracie, our Harmful Algal Bloom specialist, taught me that even the most “boring” things are fascinating when someone is truly passionate about them (“boring” is in quotes because I can’t call phytoplankton boring anymore. And zooplankton? Whoa. That stuff is crazy).

Lance taught me that people are always surprising – his innovative ways for dissecting fish were far from what I expected. Also, Tim owns alpacas. I didn’t see that one coming. It’s the surprising parts of people that make them so fun, and it’s probably why our team worked so well together on this voyage.

I can’t wait to bring all of this back to my classroom, specifically to my math class. My students have already been asking me lots of questions about my life at sea, and I’m excited to take them on my “virtual voyage.” This is going to be a unit in my eighth and ninth grade math classes where I show them different ways math was used aboard the ship. I’ll have pictures and accompanying story problems for the students to figure out. They’ll try to get the same calculations that the professionals did, and then we’ll compare data. For example, did you know that the NOAA Corps officers still use an old-fashioned compass and protractor to track our locations while at sea? They obviously have computerized methods as well, but the paper-and-pencil methods serve as a backup in case one was ever needed. My students will have fun using these on maps of my locations.

They’ll also get a chance to use some of the data the scientists took, and they’ll see if they draw the same conclusions the NOAA scientists did. A few of our team were measuring pyrosomes, so I’ll have my students look at some pyrosome data and see if they get the correct average size of the pyrosome sample we collected. We’ll discuss the implications of what would happen if scientists got their math wrong while processing data.

I am so excited to bring lots of real-life examples to my math classroom. As I always tell my students, “Math and science are married.” I hope that these math units will not only strengthen my students’ math skills, but will spark an interest in science as well.

This was an amazing opportunity that I will remember for the rest of my life. I am so thankful to NOAA and the Teacher at Sea program for providing this for me and for teachers around the country. My students will certainly benefit, and I have already benefited personally in multiple ways. To any teachers reading this who are considering applying for this program – DO IT. You won’t regret it.
