Science and Technology Log:

Well, I’m back on dry land, with lots of great memories of sharks, big and small, and all the interesting people who I spent two weeks with on the Oregon II.  And let’s not forget the red snappers either.

Cuban dogfish: The smallest species we caught

On our last day, we fished at a couple of sites right off the coast of Alabama and caught lots of sharks, plus a new species of grouper for the trip.  The scamp grouper (Mycteroperca phenax) is apparently not frequently found on the longlines along the coast of Texas but becomes more common along the coasts of Mississippi and Alabama and up the Eastern Atlantic coast as well.

ScampTail

Tail of a Scamp Grouper

The groupers are mostly protogynous, meaning that when they become sexually mature, they are always females.  Only later in life, when they have grown bigger (and have the right environmental influences), do they transition to males.  This species can live for more than 30 years, but that’s actually relatively short for a lot of the grouper species, some of which can live to 60 years or more. Scamp grouper come together in groups to reproduce, so this makes them vulnerable to overfishing.  The management councils take this into consideration when making a management plan and will close off areas known to be spawning grounds during the reproductive season.  These are also great areas to target as Marine Protected Areas.

ScampHead

Scamp Grouper being measured

All of this knowledge about the scamp grouper (and other species we encountered on this survey) was gained through careful scientific research.  As mentioned before, the long line survey was started in 1995 and has been conducted using the same methods every year since then.  These data are used by fisheries managers to set catch limits and detect changes that might indicate problems for the species living in these areas.  In other words, the science forms the basis for decision making and planning.

This is true for the various surveys that NOAA conducts in the Gulf each year.  The Groundfish Survey, for example, provides vital information about the extent of the Dead Zone off the coast of Louisiana, by measuring dissolved oxygen levels on the sea floor as part of the survey.  This data tells us that we need to continue to work on controlling nutrient inputs into the Mississippi River from agriculture lands and cities that span much of the eastern United States.  Scientific research also tells us that we need to be planning for and mitigating the effects of the looming problem of climate change.

Climate change will certainly bring about significant change to the Gulf.  As ocean temperatures rise, water becomes less dense and therefore takes up more space.  Along with continued melting of land-supported ice in the polar regions, this is contributing to a cumulative increase in sea level of 3.2 mm per year (https://oceanservice.noaa.gov/facts/sealevel.html).  In the Gulf, this increase will particularly impact estuarine ecosystems that are rich nurseries for many fish species and are extremely productive habitats.

One of the predictions of many climate models is that increased global temperatures are likely to bring about more frequent and more intense hurricanes.  This 2017 hurricane season is a stark reminder of the devastating impacts that hurricanes can have, even when we have the scientific tools to predict approximately where and when the storm will make landfall.

Finally, the increase in global temperatures will make the regions surrounding the Gulf less pleasant places for people to live.  The summers are already very hot and humid, and a degree or two hotter will make a lot of difference in the livability of the region.

We know all of this through careful scientific research, and there is a consensus amongst scientists that this is happening.  To prepare for the effects of climate change and to know how to best minimize those effects, we must continue to collect data and do science.  After all, what is the point of scientific research if we don’t use the results to make better choices and to address the problems that are facing us?

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.

MackerelBaitedHooks

Hooks baited with mackerel

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.

SamplingStations

Sampling stations for 2015 Longline survey from 2015 Cruise report

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.

Measuring and tagging shark in the cradle

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.

Sunday afternoon, September 17

I arrived in Pascagoula, Mississippi in the late afternoon on Saturday after a long day of travel.  Things were so quiet on the ship that evening as most of the crew had gone home during the break between legs of the survey.  It was great to be met and shown around by a friendly face, the Officer on Duty (OOD) David Reymore.  I definitely was feeling a bit like a fish out of water, even though we hadn’t even left the dock yet. As people start to arrive back on the ship, they all know their role and are busy getting ready for our departure later on today. It’s a good experience to feel like you’re out of your element every now and again and I guess a small part of why I decided to apply for a Teacher at Sea position in the first place.

NOAA

As I was preparing to depart on this adventure and was explaining that I was going to be a NOAA Teacher at Sea, I had a number of people ask me what NOAA stood for, so I thought I’d provide a bit of information about what they are and what they do.  First, NOAA stands for the National Oceanic and Atmospheric Administration, and the name definitely suggests the broad mission that the agency has.  Their mission involves striving to understand the oceans, atmosphere, climate, coastlines and weather and making predictions about how the interactions between these different entities might change over time.

That is a tall order, and the agency is divided up into different offices that focus on different aspects of their mission.  The National Weather Service, for example, is focused on forecasting the weather and makes predictions about things like where hurricanes will travel and how intense they will be when they get there.  The National Marine Fisheries Service is tasked with studying the ocean resources and habitats in U.S. waters and to use that understanding to create sustainable fisheries.

So far, I’ve met many people that I’ll be sharing the boat with over the next two weeks.  They have all taken time to introduce themselves and talk for a bit, even though I know that they’ve got tons to do before we sail.

Sunday evening

Well, we’re underway towards our first sampling sites off the coast of Brownsville, Texas.  The seas are really calm, and I’m sitting up on the deck enjoying the light breeze and digesting the delicious dinner of jambalaya, vegetables and blackberry cobbler.  On our way out from Pascagoula, we saw a few dolphins, beautiful white sand barrier islands and mile after mile of moon jellies, but now we’re no longer in sight of land.

We’ve passed an occasional oil rig off in the distance but haven’t seen much else.  The sun just set behind just enough clouds to make the colors spectacular and then as I was climbing down the stairs, I saw a handful of dolphins playing in the boat’s wake.

Monday, September 18

Today will be a full day of travel to reach our fishing grounds.  Assuming we continue to make steady progress, we should arrive in the late afternoon or early evening on Tuesday to begin fishing.  We will be baiting 100 hooks that, once deployed, will remain in the water for an hour before we pull them back in.  We’ll be fishing in a variety of depths while working our way back towards Pascagoula.  We practiced some drills this afternoon, including a “man overboard” simulation, using a couple of orange buoys.  They deployed a rescue boat and had retrieved the buoys in a matter of minutes.  I have to admit that watching them get out there with such speed and skill put me at ease.

Introduction

Welcome to my Teacher at Sea blog!  My name is Kate Schafer, and I am a teacher at the Upper School at the Harker School in San Jose, California, right in the middle of Silicon Valley.  I teach biology, marine biology and food science to mostly juniors and seniors.  This may seem like an odd mix of courses, but I am so fortunate to be able to teach students about all my favorite topics.  I have heard that the food is delicious on the Oregon II, and I’m interested in learning more about the challenges of keeping a crew fed when you can’t pop down to the corner grocery store when you realize that you forgot to order that crucial ingredient.  I have spent many hours on the ocean, and spent six years studying coral reefs in Belize, Central America, but I’ve never been to sea on a research vessel.  I’m thrilled to have that opportunity and to share it with my students.

Weather Data

The weather has been a big topic of conversation of late here in San Jose.  Two weekends ago set all-time record high temperatures throughout the Bay Area, even along the coast.  Living in close proximity to the ocean, we expect relief from that rare hot day to come rather quickly, but the heat lingered for days.  We’re back to normal fall weather as I head off, though.  This morning is cool and seasonable.  I know from growing up in Atlanta, Georgia, that I’m heading to warm and humid conditions on the other end of my travels.

Science and Technology Log

On this research cruise, we will be conducting long line surveys, looking at shark and red snapper populations in the Gulf of Mexico.  I will report more on where we are going and what we’re studying once the leg of the survey begins. There are multiple legs to the survey, and I’ll be joining in for the fourth and final leg.  It has been a tumultuous time in the Gulf over the past few weeks, and it will be interesting to learn about how this has impacted the coastal waters in the area we will be surveying.

Personal Log

I am sitting in the airport in San Jose, ready to board my flight to Dallas, en route to Gulfport and my final destination of Pascagoula, Mississippi.  Wow! It’s been a frantic week of getting all sorts of last minute pieces put together to allow things to, hopefully, run smoothly in my absence.  It’s early morning, so I’m still in a bit of a groggy cloud, making the fact that I’m actually heading off on this adventure all the more unreal.

Even the grogginess cannot stifle my excitement, though, as I head off for two weeks of working with scientists and collecting data.  As I was packing last night, I couldn’t help but be reminded of all the previous trips I packed for more than 15 years ago to conduct field research on coral reefs in Belize.  I was studying a type of crustacean called the stomatopod and learning about the role that they play in coral reef ecosystems, how they interact with other species like pygmy octopus and crabs, their main source of prey.

I am thrilled to be heading out on this research trip and feel so fortunate for the opportunity.  I look forward to questions from you about what we are doing and learning on our voyage.  Check in frequently for updated blog posts once the trip commences.

Science and Technology Log

We have been sampling along the coast of Florida, Alabama, Mississippi, Louisiana, and Texas at varying depths – “A” stations ( 5- 30 fathoms), “B” stations (30 -100 fathoms) and “C” stations (100 – 200 fathoms). A fathom is six feet or approximately 2 meters. The longlines are baited the same – mackerel on 100 hooks spread out across one nautical mile and then set on the bottom of the ocean. As we reel in the long line, the click and whine of the line as it’s being spooled, we wait in anticipation of what it may bring. Each station yields something different and you never know what you are going to get. Below is a list of some of the animals we have encountered.

 

IMG_6286

baby hammerhead

Shark species: blacktip, sharpnose, blacknose, scalloped hammerhead, great hammerhead, bull, tiger, spinner and bonnet head (to learn more about each of these species, select it for a NOAA fact sheet).

IMG_6273.jpg

Scallop Hammerhead in cradle

Other animals: southern ray, cownose ray, roughtail stingray, red snapper, black drum, sharksuckers, catfish, red drum, yellowedge grouper, king snake eels and even some blue crabs.

So why survey sharks? Did you know that people are one of only a few species that prey on sharks — killer whales and other sharks are the others– killing over a hundred million per year?* Sharks are apex or top predators in an ocean food web and play a vital role in keeping this food web in balance. With the hunting of sharks as well as over fishing the prey that sharks eat we are disturbing the natural balance. This survey is used determine the number of sharks and other species that are present in the Atlantic Ocean including the Caribbean Sea and the Gulf of Mexico. With these numbers, the National Marine Fisheries Service (NOAA Fisheries) regulate how many sharks, swordfish and tuna can be harvested without impacting the total population. In the Pacific Ocean, NOAA fisheries work with fisheries in developing how to best manage sharks.

IMG_6731

red snapper

Apex predators in any ecosystem are vital to the health of that ecosystem. These top predators keep numbers down on the more abundant prey species and keep their numbers in check. Here is a simplified illustration of what happens when we lose apex (top) predators in an ocean ecosystem.

If the number of sharks goes down then the food the sharks eat goes up (forage fish) because they are not being eaten by the sharks. With more of those forage fish around their need for food – the zooplankton – increase. With more forage fish eating the zooplankton there are less zooplankton and their numbers begin to decrease. If there are less zooplankton then the phytoplankton numbers increase because the zooplankton aren’t around the eat them. Removing top predators from any ecosystem can have an impact on the entire food web and this phenomena is called a trophic cascade.

IMG_6489

Removing Hook

Personal Log

When people think of sharks, they think of the movie Jaws. Unfortunately this has given sharks a bad reputation and has vilified these animals that are essential to the ocean food webs. Sure, there have been shark attacks, but did you know that more people are killed each year by electrocution by Christmas tree lights than by shark attacks? When people imagine sharks, they think of enormous sharks that eat everything in sight. The reality is that sharks come in all sizes and shapes. A mature Atlantic sharpnose shark will only get to be 3.5 feet long with the world’s smallest shark being the dwarf lantern shark that can fit in the palm of your hand. The largest shark is the harmless-to-human whale sharks that feeds primarily on plankton and can grow up to 60 feet!

Did You Know?

Scientists can tell the age of a shark by counting the rings on its vertebrae (similar to how they can tell how old a tree is by counting its rings!)

Question of the day:

What is an example of a terrestrial (land) apex predator that has been over hunted impacting the entire ecosystem?

We have been experiencing some rocking and rolling out here due to the hurricanes that are occurring to the east and the west of us as we sit in the relatively calmer waters off the coast of Texas and Louisiana. We have experienced 6 – 8 foot waves so far on our survey and the ship is being maneuvered to try and find the calmest spots so we can continue to do our work.

So what makes a wave a wave?

Check out this link to learn what makes a wave a wave!

https://oceanservice.noaa.gov/facts/wavesinocean.html

 

Waves are part of the experience. Below is a poem written by the scientists and crew of the Oregon II on an earlier survey. Here are a few vocabulary words that you may not know to help you interpret the poem.

 

Crest – the highest part of the wave
Trough – the lowest part of a wave
Muster – to call together
Haul back – the process of bringing in the longline
Bridge – where one controls the ship

Here is a poem written by some of the scientist and crew of the Oregon II about rough waters on an earlier expedition.

 

Trough-Man

The crew knows he’s on the job,
when the Ship starts to bob.

They know he’s at the wheel,
‘cause on the hip she does heel.
Trough-Man

On the Deck the haul-back team does muster,
while on the Bridge he robs sleep with the bow thruster.

You’ll always wake up in a funk,
‘cause you’ve been rolled out of your bunk.
Trough-Man

Sometimes you may wonder if he can
find the trough in a mug or a coffee can.

On this Ship you can’t even shave,
‘cause you never know when she’ll hit another wave.
Trough-Man

When the boat’s wallowing like a stuck pig,
you know he’s on the Bridge doing a jig.

For the rail you will grab,
when the boat does its crab.
Trough-Man

When you’re eating off your neighbor’s plate,
you know he’s your Shipmate.

If you can’t hold your food down and your stomach is off,
you know your riding in the trough.
Trough-Man

This poem is to all boat drivers, because they are put in the position of going from point A to point B no matter the sea state.

Personal Log

We have had calm days where the water is like glass and other days with wind waves of up to 8 feet! I have come to appreciate the numerous handrails available all around the ship as well as learning to make sure my drawers and cabinets are secured. Nothing like waking up in the middle of the night with your drawers opening and closing! Also taking a shower in these conditions are quite the adventure in itself. The last few nights have felt like I am sleeping in a swinging hammock. There are also some nice features on the ship to keep items in place.

 

 

Here are some photos of the things I appreciate when the boat is rocking and rolling —  handrails that are located everywhere, hooks that keep doors open and holes in the picnic table to keep your drink from spilling!

Did You Know?

An oceanographic front is an area where two distinct water masses meet. Here is the one that we encountered on this last station. Why are these fronts important to birds and marine life? Extra credit for this bonus question!

Science and Technology Log

The weather has been a big topic of conversation on this survey and for good reason. The original plan was to fish off the coast of Texas from Brownsville to Galveston. Due to Hurricane Harvey and possible debris in those waters, the survey changed course to sample off the coast of Florida. As we motored east, Irma was building up to a category 5 hurricane.

IMG_6031

Captain Dave

 

Captain Dave has been keeping a keen eye on the weather and after a few days of fishing off the coast of Florida, we headed back toward Pascagoula, Mississippi to pick up a crew member and let another off to tend to his family in Florida which is in the current path of Irma. We have been looking at the various computer modeling showing where Irma will land and this determining our path. Fortunately, a cold front to the west of us is pushing Irma east which will allows to stay out instead of docking and ending the survey early. This cold front is unusual for this time of year according to the Captain. Earlier models showed Hurricane Irma hitting the west side of Florida into the Gulf of Mexico where we are which would end our survey. Now, with the updated weather, we may get to stay out as planned but staying close to Mississippi and then heading West to work off the coast of Texas and Louisiana.

Daily updates and rerouting due to weather

This ship is part of the Ship of Opportunity Program (SOOP). This program enlists ships to collect weather data that is sent to the National Weather Service (a line office of NOAA) every hour. This is the data that supplies information to weather forecasters! Information that is gathered includes wind speed and direction, barometer reading, trend in pressure over the past few hours, as well as wind, wave and swell information. Have you every noticed on TV that the weather reports have a notification that states the data is coming from NOAA? Weather forecasters get weather information from ships out in the ocean like the one I am on.

IMG_6323

another beautiful sunset from the top deck

This morning I headed up to the bridge to chat with Captain Dave. Here are some of the questions I asked.

Q: How long have you been a captain?

CD: 9 years

Q: What got you interested in this type of work?

CD:I grew up in Mississippi where you hunt and fish so when I got out of high school I always wanted to work on the water due to my upbringing. We were always taking out the boat to hunt or fish growing up. It’s in my blood.

Q: What is your schooling? What advice would you give someone that is interested in this as a career?

CD: I graduated high school in 1980 and made my living on the water commercial fishing and working on the oil rigs until January 4, 1993. I started as a deck hand and worked my way up to Commanding Officer (CO). I’ve been on the Oregon II 25 years. The hardest thing was taking the test to be a Master.

Captain Dave is a civilian Master which is rare – there are only two in the NOAA fleet. Most NOAA ships are run by NOAA Corps Officers. 

Q: What is the biggest storm you have seen?

CD: East of Miami, Florida in the gulf stream we were seeing 12-15 foot seas. The engine room calls the bridge regarding a busted intake valve. The boat was sinking. The engineers were in knee deep water and were able to find the broken valve and stop the flooding. In another 7 minutes the generator would have been under water and we would have lost power and would be forced to abandon ship in 12-15 foot waves.

Q: Is this weather unusual for this area this time of year?

CD: We never get a NE wind bringing in cooler weather which is probably what is turning Hurricane Irma. Normally it’s blazing hot here with southwest winds at 10 miles. This cold front is the reason we are not going in.

Check out this cool animated site for wind patterns. You can see how the hurricanes impact the flow of air.

Personal Log

So far the seas have been calm and I keep expecting things to pick up because of all the weather happening around us. Sleeping pretty good with slow rocking of the ship and we will see how I do with some bigger swells. The crew has been super helpful in doling out advice from how keep from getting seasick ranging from eating, drinking and even how best to walk! I’m listening to all this advice and so far so good. I do wonder how much of Hurricane Irma we will feel now that we are heading west a few hundred miles.

Spinner shark

We have caught a few sharks and I am excited to catch some more. Other critters we have caught were a bunch of eels and a suckerfish. On yesterday’s shift I learned how to tag one of the big sandbar sharks. She was about 6’ long. The night crew caught a 10’ tiger shark! Maybe we will get lucky on today’s shift as I would love to see more sharks and handle some of the smaller ones.

IMG_6103

suckerfish

Update: Last night our shift brought in 16 sharpnose sharks so things were busy. These sharks don’t get much bigger than 3 ½ feet. All of the ones we pulled in last night were female. The oceans have gotten a bit rougher with swells 4-5 feet! I have gained a new appreciation for all the rails available along the corridors of the ship and have learned to make sure my door is clicked shut as well as all the cabinets and drawers. Nothing like waking up to drawers slamming open and shut in the middle of the night!

Did You Know?

A Captain of the ship can be ranked as a Captain or a Commander within the NOAA Corps but a civilian does not hold a commissioned rank because they are not in the NOAA Corps and is called a Captain since he holds a Master license gained by taking extensive coursework and an intensive exam through the United States Coast Guard.
