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!

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

Amanda Andrews-Survey Technician

Amanda Andrews — Survey Technician

Job Title:
Survey Technician
Office of Marine and Aviation Operations
National Oceanic and Atmospheric Administration

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

Nicole Charriere- Sea-going Biological Technician

Nicole Charriere — Sea-going Biological Technician

Job Title:
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.
