Science and Technology Log:
I thought I would end my trip on the Henry B. Bigelow with some fun facts!
.
Did you know?
The Fisheries Scientific Computer System (FSCS) is able to prompt the data recorders with all actions needing to be performed for a particular species. It is coded with unique barcodes for every sample taken. Back in the laboratory all scientists receiving samples can receive all the information taken about the given organism by scanning this unique barcode!

Did you know?
Science crew operating on the back deck are required to wear an Overboard Recovery Communications Apparatus (ORCA). This system if it is activated sends a signal by way of radio frequency to a receiver on the ship’s bridge. This system responds immediately to the ship receiver and has a direction finder to help locate the man overboard.

It would take me hours to go through all of the amazing creatures we caught and surveyed on this trip, so I thought I would write some fast facts about some of my favorites! Enjoy!
.
Did you know?
The male spoon arm octopus has a modified arm that passes spermatophores into the oviducts of the female. Pretty neat stuff!

Science and Technology Log:

Ocean acidification have been the buzz words in the shellfish and coral reef world for the last few decades, but how will changes in our ocean’s pH affect our coastal fisheries resources? The Henry B. Bigelow is host to another project to help monitor this very question. The ship has an automated system that draws in surface seawater through an uncontaminated line and feeds it to a spray head equilibrator (seen in photo). Here, this instrument measures the partial pressure of carbon dioxide through an infrared analyzer. Standards are used to automatically calibrate the instrument periodically so it can take data while the fish are being counted and measured. How great is that!

Partial pressure Carbon Dioxide system schematic
Partial pressure Carbon Dioxide system schematic

It has already been shown and well documented that our oceans are getting more acidic. Something to remember is that our ocean and atmosphere are always in equilibrium in terms of carbon dioxide. Therefore, if we emit more carbon dioxide some of that will be absorbed by the ocean. The rapid changes in development since the industrial revolution have led to more carbon dioxide in our atmosphere and therefore, over time, more diffusing into the ocean. The amount of carbon dioxide our ocean is absorbing has changed its chemistry. Increasing partial pressure of carbon dioxide (through several chemical reactions) makes the carbonate ion less available in the ocean (especially the upper layers where much aquatic life abounds).

This does not mean the ion isn’t there, it just means it is less available. Now why is this important to fisheries? Well, many organisms are dependent on this carbonate ion to make their tests, shells, and skeletons. They combine it with the calcium ion to make calcium carbonate (calcite, aragonite and other forms). If they can’t properly calcify this affects a large range of functions. In terms of commercial fisheries, scientists want to know more how acidification will affect commercial species that make their own shells, but also the fish who call them dinner. Ocean acidification has also been shown to affect other food sources for fish and reproductive patterns of the fish themselves. The fish research at NOAA will concentrate on the early life history stages of fish, as this is their most vulnerable phase. The research priority is analyzing responses in important calcifying shellfish and other highly productive calcareous phytoplankton (base of the food chain). To learn more in detail from NOAA please read this. By monitoring the partial pressure of carbon dioxide at fisheries stations over time, scientists can compare this data with the health, location, and fitness of much of the marine life they survey.

Personal Log:
As my time on the Bigelow is drawing to a close, I wanted to highlight some of the amazing women in science on board the ship who play key roles in the research and upkeep of the ship. I have asked them all a few questions about their job and for some advice for young women who would like to take on these various roles in the future! Since we have so many talented women on the ship, please stay tuned for another addition!

Amanda Tong

Amanda Tong
Amanda Tong — Fisheries Data Auditor, Northeast Fisheries Observer Program

Job Title:
Fisheries Data Auditor with the Fisheries Sampling Branch
Program: Northeast Fisheries Observer Program
NOAA Fisheries Service
National Oceanic and Atmospheric Administration

What she does:
Amanda is responsible for working with the Fisheries Data Editor to be the collator of information received from the Fisheries Observers and more specifically the Fisheries data editors. She is looking for any errors in data reporting from the Fisheries Observer Program and working with the editors who are in direct contact with them.

If you remember in my last blog, I talked about the otolith and length information going to the Population Dynamics group who make models of fisheries stocks. The data from the Fisheries Biology program is also given to this end user. This way the models take into account actual catches as well as bycatch. Other end users of the data are graduate students, institutions and other researchers.

Amanda’s favorite aspect of her job:
Amanda likes being the middle person between the fishing industry while also working for the government. She likes seeing how the data change over the years with changes in regulation and gear types. She finds it interesting to see how the fisheries change over time and the locations of the fish change over time. She also loves hearing the amazing stories of being at sea.

What type of schooling/experience do you think best set you up for this job:  Amanda received a degree in marine biology, which she thinks set her up perfectly. She suggests however that the major doesn’t have to be so specific as long as it has components of biology. The most important aspect she feels was volunteering and learning how to do field work with natural resource management, even if on land. Learning how to properly sample in the field was really important. Amanda is a former Fisheries Observer so she also knows the ins and outs of the program that collects the data she is auditing. This helps her look for easily recognizable errors in the data sets from all different gear types. By gear types I mean trawls vs. gill nets vs. long lines etc.

Robin Frede

Robin- Fisheries Data Editor
Robin — Fisheries Data Editor

Job Title:
Fisheries Data Editor
Branch: Fisheries Sampling Branch
Program: Northeast Fisheries Observer Program
NOAA Fisheries Service
National Oceanic and Atmospheric Administration

What she does:
Robin deals directly with the Fisheries Observers. Fisheries observers are assigned to different boats and gear types up and down the eastern seaboard to record catches and bycatch as well as run sampling protocols. After each trip Robin checks in with the observer for a debrief and they send on their data to her. It is her responsibility to take a good look at the data for any recognizable errors in measurement or sampling error. Since she was a fisheries observer herself, she can coach the observers and help mentor them in sampling protocol and general life at sea. Once she reviews the data set it gets collated and sent off for review by the Fisheries Data Auditor.

Favorite part of her job:
Robin’s favorite part of her job is being a mentor. Having done the program herself previous to her current job she has a full understanding of the logistical difficulties that observers face at sea. She also is well versed in all of the aspects of sampling with different gear types. Since she is no longer at sea on a regular basis one of her favorite aspects is getting to go to sea on a shadow trip to help out new observers. She also participates in one research trip (currently on the Bigelow now), and one special training trip each year.

What type of schooling/experience do you think best set you up for this job:
Robin suggests a Biology basis for this type of job and lots of experience volunteering with field work. Understanding the methodology and practicing are very important to accurate data collection. Accuracy and practice make her job as an editor a lot easier. If you think you might be interested in this type of career Robin suggests the Fisheries Observer Internship. You can find out if you like spending a lot of time at sea, and this line of work, plus get exposure to many sampling protocols.

Amanda Andrews

What she does:
Amanda wears many hats and goes wherever the Henry B. Bigelow goes. She is in charge of supervising data collection and analysis. She is the liaison between the ship’s crew and the scientific crew.  She is in charge of the scientific equipment function and maintenance. Amanda is the go-to person on each survey during sampling. She also is responsible for helping crew on the back deck.

 Favorite Part of her Job:
Amanda’s favorite part of her job is that the ocean is her office. She lives aboard the Bigelow and where it goes, she goes.

What type of schooling/experience do you think best set you up for this job:
Amanda started out working on the back deck of NOAA ships and progressed to become a survey technician. She suggests having a good background in marine biology and biology in school, but more importantly always be willing to learn.

Nicole  Charriere

Aboard the ship currently: Day Watch Chief
Official title: Sea-Going Biological Technician
Branch: Ecosystem Survey Branch
Northeast Fisheries Science Center
National Oceanic and Atmospheric Administration

What she does:
Nicole’s job entails being at sea between 120 and 130 days a year! She specifically goes out on Ecosystem Survey cruises that she can do some choosing with.  She goes out on bottom trawling, scallop, and clam survey trips. Her job is to help the scientific party either as a watch chief or chief scientist. She has to handle all sampling as well as fully understand all of the survey techniques. She is well versed in the Fisheries Scientific Computer System (FSCS) and needs to know her fish and critter ID. She is the one responsible for sending down all the species already pre-tagged with their ID.  On top of all that she is also responsible for monitoring the censors on the net and regularly replacing them.

Favorite part of her job:
Nicole’s favorite part of her job is not being in an office and being at sea. Her work environment is always changing, as the scientific crew is always changing and so are the species she works with. She enjoys working and meeting new people each cruise.

What type of schooling/experience do you think best set you up for this job:
Nicole says to get to where she is you have to work hard. You might not be the one with the most experience, but if you work hard, it doesn’t go unnoticed. She also suggests networking as much as possible. Get to know what people do and learn from them. She says studying biology was helpful, but not an absolute necessity. Above all, make sure you love what you do and make sure you are excited to go to work.

Science and Technology Log:

It’s day 13 aboard the Henry B. Bigelow and we have made the turn at our southern stations off the coast of North Carolina and are working our way back to port at some of our inshore stations off the coast of Maryland. You may wonder how each of the stations we sample at sea are chosen? The large area of Cape May to Cape Hatteras are broken into geographic zones that the computer will assign a set amount of stations to, marking them with geographic coordinates. The computer picks a set number of stations within each designated area so all the stations don’t end up all being within a mile of each other. Allowing the computer system to pick the points removes human bias and truly keeps the sampling random. The vessel enters the geographic coordinates of the stations into a chartplotting program in the computer, and uses GPS, the Global Positioning System to navigate to them.  The GPS points are also logged on a nautical chart by the Captain and mate so that they have a paper as well as an electronic copy of everywhere the ship has been.

You may wonder, how does the captain and fishermen know what the bottom looks like when they get to a new point? How do they know its OK to deploy the net? Great question. The Henry B. Bigelow is outfitted with a multibeam sonar system that maps the ocean floor.  Some of you reading this blog might remember talking about bathymetry this summer. This is exactly what the Bigelow is doing, looking at the ocean floor bathymetry. By sending out multiple pings the ship can accurately map an area 2.5-3 times as large as its depth. So if the ship is in 20 meters of water it can make an accurate map of a 60 meter swath beneath the boats track. The sonar works by knowing the speed of sound in water and the angle and time that the beam is received back to the pinger . There are a number of things that have to be corrected for as the boat is always in motion. As the ship moves through the water however, you can see the projection of the bathymetry on their screen below up in the wheelhouse. These images help the captain and the fisherman avoid any hazards that would cause the net or the ship any harm.  A good comparison to the boats multibeam sonar, is a dolphins ability to use echolocation. Dolphins send their own “pings” or in this case “echos” and can tell the location and the size of the prey based on the angle and time delay of receiving them back. One of the main differences in this case is a dolphin has two ears that will receive and the boat just has one “receiver”. Instead of finding prey and sizing them like dolphins, the ship is using a similar strategy to survey what the bottom of the sea floor looks like!

Personal Log:

The last few days I have been trying my hand at removing otoliths from different species of fish. The otoliths are the ear bones of the fish. Just like the corals we have been studying in Bermuda, they are made up of calcium carbonate crystals. They are located in the head of the bony fish that we are analyzing on the cruise. A fish uses these otoliths for their balance, detection of sound and their ability to orient in the water column.

If you remember, at BIOS, we talk a lot about the precipitation of calcium carbonate in corals and how this animal deposits bands of skeleton as they grow. This is similar in bony fish ear bones, as they grow, they lay down crystalized layers of calcium carbonate. Fisheries biologist use these patterns on the otolith to tell them about the age of the fish. This is similar to the way coral biologists age corals.

I have been lucky enough to meet and learn from scientists who work specifically with age and growth at the Northeast Fisheries Science Center Fishery Biology Program. They have been teaching about aging fish by their ear bones. These scientist use a microscope with reflected light to determine the age of the fish by looking at the whole bone or making slices of parts of the bone depending on what species it is. This data, along with lengths we have been recording, contribute to an age-length key. The key allows biologists to track year classes of the different species within a specific population of fish. These guys process over 90,000 otoliths a year! whew!

The information collected by this program is an important part of the equation because by knowing the year class biologists can understand the structure of the population for the stock assessment.  The Fishery Biology program is able to send their aging and length data over to the Population Dynamics Branch where the data are used in modeling. The models, fed by the data from the otoliths and length data,  help managers forecast what fisheries stocks will do. It is a manager’s job to the take these predictions and try to balance healthy fish stocks and the demands of both commercial and recreational fishing. These are predictive models, as no model can foresee some of the things that any given fish population might face any given year (ie food scarcity, disease etc.), but they are an effective tool in using the science to help aid managers in making informed decision on the status of different fish stocks. To learn more about aging fish please visit here.

You can see here is an otolith that is 1+ years old. It was caught in September and that big 1st band is its Year 0. You can see that the black dot demarks the fish turning 1. You can then see the Summer growth but not yet the winter growth. This fish has not yet turned 2, but it will Jan 1st of the next year.

Science and Technology Log

The purpose of our mission aboard the Henry B. Bigelow is the 1st leg of groundfish surveys from Cape May all the way down to Cape Hatteras with the Northeast Fisheries Science Center. The scientists aboard the ship are interested in both the size and  frequency of fish at different targeted geographic locations. We will be sampling using a trawl net at about 130 different stations along the way, some inshore and some offshore. We will be using a piece of technology called the Fisheries Scientific Computer System (FSCS). This system will allow us to accurately take baskets of different species of fish and code them for their lengths into a large database. This will give us a snapshot of fisheries stocks in the Northeast Atlantic by taking a subsample. The computer system also allows us to see if any other things need to be done with the fish once they are measured. Tasks like otolith (I’ll tell you about these later!) and gonad removal, fin clips or whole organisms sampling may also be done. The computer system will allow us to label each of these requests and assign it a code for scientists requesting samples from this cruise. Additionally, there are scales along with the system for recording necessary weights. We will be sorting fish first by species, and then running them all through the coded FSCS which you can see in the photo below.

Pre-cruise Personal Log

In a little over two weeks I am set to board NOAA Ship Henry B. Bigelow at the Newport Rhode Island dock on a NOAA Fisheries survey cruise as a part of NOAA’s Teacher at Sea program.  My name is Kaitlin Baird, and I am a science educator at the Bermuda Institute of Ocean Sciences. At this U.S. based not-for-profit, I get to teach students from 2nd grade all the way up to my Road Scholar program. Many of my students come to visit the Institute from all over the world to learn more about the ocean around Bermuda. I have just finished up with 24 interns for the summer as a part of BIOS’ Ocean Academy and I am set for the next adventure!

I am originally from New Jersey where I grew up finding critters along the beaches of the Jersey shore. My mom always used to laugh when I tried to keep critters alive in the outdoor shower. I was one of those kids that was always in the water. Probably no big surprise that I went on to study and teach marine biology!  I am looking forward to my critter cruise and even more so looking forward to learning new species of the Northern Atlantic.

Sargasso Sea Map
The Sargasso Sea is the only sea without a land boundary and entirely in the Atlantic!
Have a look at this NOAA map above.

Being in the Sargasso Sea in Bermuda, we are subtropical. We get a whole suite of coral reef, seagrass and mangrove species. You can see some photos of some critters I’ve spotted this summer!

This slideshow requires JavaScript.

I have a few goals for the cruise:

  1. Learn as much as possible from the scientists on the cruise
  2. Participate in taking and understanding data collected on the cruise
  3. Posting and taking photos of some of our critters surveyed on the cruise
  4. Explaining to my students what we are doing and why it’s important!

If there is anything you would like to learn more about as I travel, let me know in the “comments” section below!

Wish me luck, I’m headed North!
