First guest blog post: LTJG Johns!

We have our first guest blog post of the survey! We feature our OPS officer for leg 1 of NF1802, LTJG Johns!
LTJG Johns shared with the blog: “My name is LTJG Kristin and I studied Biological sciences at Rutgers University. I am the Operations Officer on the NOAA Ship Nancy Foster.  As the operations officer, my job is to ensure the science gets completed in a safe and efficient way. My goal is to communicate and coordinate with the science party, ship's bridge team, and crew for a successful project and happy team! My job is to look out the window at a beautiful ocean and help science happen. Oh, and drive ships, 

LTJG Johns in much colder climate!

What’s better than that?!”
An officer “OPS” leads and communicates on behalf of the ship’s officers and multiple ship departments. It can be a challenging role, but in my opinion, it’s also very fun because in one ‘field season’ they get to learn about a lot different topics that can range from mapping the sea floor, to projects that use scuba diving as a tool to monitor fish populations, to collecting awesome larval fish, to deploying extremely sensitive scientific equipment to monitor the ocean in real time. If you have any questions for LTJG Johns, please comment below and feel free to learn more about the NOAA Commissioned Officer Corps or see previous blog posts by other NOAA Corps officers (Norton, Zygas)

Featured today: LTJG Niki Norton

Today’s post features LTJG Nikita "Niki" Norton, and officially welcomes her to the FORCES Lab family! Niki is the current "Florida Bay Operations Officer," replacing LTJG Aras Zygas.  As a part of the NOAA Commissioned Officer Corps, she operates sampling platforms to facilitate scientific research and provides logistical and administrative support to NOAA’s mission.  She shared with the blog: 

Niki  records the flowmeter data into our logsheets

"For the last three years, I was assigned to the NOAA Ship Bell M. Shimada out of Newport, Oregon, conducting fisheries surveys from Vancouver, Canada all the way down to San Diego, CA.  Along with the responsibilities of being Navigation Officer and Medical Person in Charge, my primary duty was to “drive” the 210’ Fisheries Survey Vessel every day for 200+ days a year

"Many of the sampling techniques that are routinely performed by research groups on the West Coast to collect plankton are exactly the same as those conducted by the FORCES lab to collect larval fish! 

"This included Bongos, Neustons, MOCNESS, and CTDs on many of the projects.  We performed extensive mid-water stern trawls with a net the size of a football field to catch fish like Pacific hake and sardine. We followed and tagged endangered Resident Killer Whale pods and acoustically monitored beaked whales at 4000m depth.  The remainder of the year, the ship completed Remotely Operated Vehicle (ROV) transects and hydrographic missions in the Farallons and Channel Islands.

"While many of the operations may be the same, this new job with the Southeast Fisheries Science Center is quite different - as is the scenery!  Rather than the whipping cold wind of the Pacific Northwest, the hot sun in the Caribbean and Gulf of Mexico is one of my favorite parts of the job. With the FORCES Lab, I get to work "on deck" to deploy and recover gear, wash down nets, assist with station planning, and see the plankton and water samples we catch up close!

"When I am not underway as a scientist, I work in the office to ensure that the lab has everything they need logistically to sail each year by assisting with cruise planning and administrative budgeting.  Now that the first year of sampling has come to a close, I am very excited to see what new projects I will get to be a part of and hope to use my background in reef fish ecology and microbiology to explore new research with the FORCES lab – while getting ready for next year!"

We are wrapping up this year's survey!... but we still have a few more posts from our scientists and will give you the numbers (eventually!)!

Rinsing down the bongo net

Meet our newest UMiami RSMAS marine science graduate, Alanna (Loni) Mnich! Loni has been a volunteer at the FORCES Lab and she shares some of her experiences on her first research survey aboard the NOAA Ship Nancy Foster.

Decked out with safety gear, ready for deployment

She shared with the blog: “My goal for this cruise is get my first at sea experience. I hope to gain a better understanding through practice of field research concepts and learn more about plankton and the early life stages of fish that I can then apply in the lab and in future studies. I am excited to see some cool organisms over the course of this cruise!

“I have been in the FORCES lab at NOAA for about a year and a half. My experience there began with sorting plankton that was collected on other oceanographic cruises, so I am excited to participate in the collection stage now. During the past months I have focused on cephalopod paralarvae as the subject of my undergraduate senior thesis, which I hope to expand into a publication.

"Over the course of this cruise I have gained significant hands on experience in plankton collection and processing, including deploying the bongo net, driving the bongo, fixing samples, as well as deploying the CTD. I will soon be able to apply these skills if I get an opportunity to participate in another cruise (hopefully in late July!). Through the rest of the summer, I will be back in the FORCES lab, likely sorting plankton from the cruise and continuing my previous work with cephalopods. In the future, I would like to gain more hands on lab and field experience and I also plan on attending graduate school to expand my studies."

Featured guest: Angie Fay Allman

Hi everyone! Today we get to have a unique perspective! One of the crew of the Nancy Foster wanted to stop by and say hello! Meet Angie Fay Ullmann. Angie was our survey technician on the night watch (midnight to noon shift) and helped us safely deploy and recover countless equipment during her watch! She is a NOAA wage mariner, her official position is an “Able-bodied Seaman” and is part of the ‘deck’ department. The science party works closely with the crew members from the survey and deck department as they facilitate multiple and often difficult tasks that include deployment, recovery, set up, break down, winch operations, small boat operations, among many others.

Angie shared with our blog from her angle:

“I have worked for NOAA for 2.5 years now and have worked on 10 of the 16 ships in our fleet. I am required to do many different tasks on each assignment, but this last cruise really stands out from the rest. I got to work more closely with the scientists and asked more questions about what they were looking for and why. I really enjoyed being more involved and the crew I worked with was a lot of fun and made the days pass by quickly. I hope the data we collected helps contribute to a better future- it gives so much more purpose and satisfaction to my work- even if I don't directly do any science, I'm helping it happen! Before this cruise, I didn't realize the scarcity of bluefin tuna nor that so many scientists try to analyze its behavior in efforts to revitalize its population.”

We truly enjoyed working with Angie and hope she will join us again in one of our next adventures on Nancy or another NOAA ship!

Night shift crew!

Featured Scientist: Rachel Thomas

Today on the blog, we have a guest post from Rachel Thomas, learn about her research objectives during this survey in the Gulf of Mexico!

Rachel takes the CTD down to 2500m in the Gulf of Mexico!

My name is Rachel Thomas and I’m a PhD student at Florida State University studying the marine nitrogen cycle with the Knapp Lab.

Filtering sea water

On this cruise, I am looking at the concentrations of nitrate, a nutrient required by primary producers, found in the upper 300 meters of the water column. Water samples are prepared using a colorimetric technique that will turn the water varying degrees of pink, depending on concentration, and analyzed at a certain wavelength. I am also collecting water samples from various depths ranging from a depth of 2500 meters and 3 meters below the surface. These samples will be taken back to FSU where we will look at the different nitrogen isotope signatures found in the water parcel.

Rachel examines nitrate concentrations

Think of an isotope signature as a fingerprint, where each source of nitrogen has its own unique fingerprint. By comparing the known signatures of each source to our water parcel, we will be able to determine where the nitrogen is coming from.

Collecting water from the CTD rosette 

It is important to understand where these nutrients are coming from to fuel primary producers in order to better understand how changes in nutrient sources will affect the GOM productivity.

Featured Scientist: Lucy Fitzgerald

Hi everyone, I'm Lucy Fitzgerald, a rising senior and a marine science/biology major at Eckerd College in St. Petersburg, FL. Though I've logged plenty of lab time, this is my first experience on a research vessel. This trip is the beginning of my NOAA Hollings internship at the SEFSC FORCES Lab in Miami. I've been on the night shift and am learning the ropes with tasks such as deploying nets and the CTD, logging data, and tracking the SVP drifter buoy. I have also gotten to see a lightning storm at night, fabulous sunrises, and tons of plankton!

My goal is to learn about the upstream process of collecting specimens before working with them in the lab this summer, looking at the age and growth of billfish. As an undergrad, I'm trying to figure out what field of research I want to go into before applying to graduate school.

Lucy learns about the array recovery from Tom and Becca

I don't have a specific research focus yet but my research experience has been primarily with paralarval squid, Doryteuthis pealeii, and looking at the effects of hypoxia on the boundary layer of the egg capsules as well as hatching rates/cues last summer and winter at the Woods Hole Oceanographic Institution. I have also looked at the population genetics of the brown Sargassum snail and bandtooth conger eel in the western Atlantic.

Being out in the open water where these species live brings a whole new perspective to my work in the lab!

Featured Scientist: Meet Jason!

Today's featured scientist is Jason Mostowy - read on for more about his cruise and future goals!

My name is Jason, I graduated from the University of  Miami in 2015 with a B.S. in Biology/Marine Science, and I've been working as a research tech in the FORCES Lab since 2013.

My main work for the lab involves processing the zooplankton samples we collect on cruises like this one - meticulously removing fish larvae and other target organisms, fitting the results into our considerable database, and dissecting larval fish for otoliths (earstones, used for ageing studies), gut contents, or genetic analysis projects. I'm also currently working on a project to characterize the larval distribution of the highly invasive Indo-Pacific lionfish (Pterois volitans/miles) in the tropical western Atlantic. Gaining a better understanding of the early life ecology of this harmful species will help scientists better predict levels of lionfish population replenishment, which in turn can be used to determine where and how often lionfish removal efforts should be performed.

This is my third year sailing aboard the Foster. I love working in the field, especially the many perks that come with going to sea - the chances to practice and expand my scientific skill set, the opportunities to get to know other scientists from a variety of disciplines, the stewards rescuing me from my unfortunate cooking for a few weeks, etc. It's been a long cruise for me; I first embarked way back on April 13th, and by the time we reach port on June 2nd I'll have spend 35 of the last 48 days at sea!

This fall - after what I hope will be a commensurately long and relaxing stint on solid ground over the summer - I plan to start graduate school where I will continue to study the factors that mediate the distribution and survival of larval fish in the GOM and Caribbean.

Outreach & Education: Nancy Opens her doors during our Progreso Open House

The ship Nancy Foster arrived for the first time to Progreso in Yucatán on May 19. On Saturday, May 20, we held an Open House event to explain the scientific research activities we carried out in the Gulf of Mexico. On this occasion we were accompanied by Dr. Mario González Espinosa, Director of ECOSUR, Dr. Magda Estela Domínguez Machín, Assistant Director of Fisheries Resources in the Atlantic of INAPESCA, Dr. Josefina del Carmen Santos Valencia, Chief of CRIP Yucalpetén, and Dr. Alvaro Hernández Flores, Professor-Researcher at MARISTA University, together with Doctorate students in Fisheries and Aquaculture Bioeconomics at the university. The students of Marine Biology (UADY), led by Dr. Alfonso Aguilar Perera, Professor-Researcher of UADY Marine Biology Faculty, were present as well as Mr. Manuel Sánchez González, President of the Yucatán Shipowners Union.

While everyone explored the ship, scientists explained the main activities carried out during our campaign in the different laboratories. In the “wetlab,” everyone got an opportunity to see the many organisms that make up the plankton using microscopes. 

The wetlab is also where each sample is carefully examined to search for tuna larvae and multiple filtrations of seawater take place. In the “dry lab” all the controls for deployment and recovery of of equipment take place. On the back deck, we saw the equipment used to ascertain nitrogen sources in relation to the plankton food-web dynamics in the habitats of the BFT.

Chief Sci Estrella Malca discusses the project goals

This is novel and exciting because, despite its importance, these research activities are being conducted for the first time in the Gulf of Mexico! Finally, on the bridge, the NOAA Corps officers showed us the state of the art navigation equipment and instruments utilized to safely and accurately lead the ship to and from our sampling locations.

Mexico and US collaborators

Students and researchers asked questions about our various activities and were surprised by the great diversity of organisms observed in the microscope and those captured on the computer screen during this survey. We would like to thank everyone for participating and to all of the port agents, the scientists, crew and officers for making this a fun and well organized event!
