Science and Technology Log

This is the 3rd and final leg of the SEAMAP Summer Groundfish Survey for 2018, taking place between July 9 and July 20 in the Gulf of Mexico. “Groundfish” refers to fish that live on, in, or near the bottom of the ocean.  SEAMAP stands for “Southeast Area Monitoring and Assessment Program,” and as the Gulf States Marine Fisheries Commission defines it, it’s an interagency (State, Federal, and university) “program for collection, management and dissemination of fishery-independent data and information in the southeastern United States” (https://www.gsmfc.org/seamap.php).

What is “fishery-independent data,” you ask? The key is understanding its converse: “fishery-dependent data.” Fishery-dependent data is gathered directly from (and in that sense, depends on) commercial and recreational fisheries.  It’s furnished by “dockside monitors, at-sea observers, logbooks, electronic monitoring and reporting systems.” In other words, it’s all about what is caught for recreational or commercial purposes. By contrast, “fishery-independent data” are collected by “scientists from NOAA Fisheries science centers and partner agencies/institutes,” who seek to gather “information on fish stock abundance, biology and their ecosystem for inclusion in stock assessments.” Roughly speaking, then, the distinction is one between a particular target and that target’s larger biological context and ecological surround. Though I had an intuitive sense of this distinction, I wanted to hold myself to account and really learn what it meant. I’m a “Teacher at Sea,” yes, but I’m really a “Learner at Sea.”

I turned to a fellow member of the day watch, fisheries biologist Adam Pollack, and, after sketching the basic distinction for me, he directed me to the website for NOAA’s Office of Science and Technology, National Marine Fisheries Service, pointing me in particular to the webpage on Stock Assessment Basics, where, among other things, one can find terms like “fishery-dependent” and “fishery-independent data” neatly defined: https://www.st.nmfs.noaa.gov/stock-assessment/stock-assessment-101). Not sure what stock assessments are? Watch theNational Marine Fisheries Service video: “The ABCs of Stock Assessments.” As I was going online to check out the definition of “fishery-independent data,” Adam told me this: “This is the world I live in.”

The purpose of the Summer Groundfish Survey is three-fold: “to monitor size and distribution of penaeid shrimp during or prior to migration of brown shrimp from bays to the open Gulf; aid in evaluating the ‘Texas Closure’ management measure of the Gulf of Mexico Fishery Management Council’s Shrimp Fishery Management Plan; and provide information on shrimp and groundfish stocks across the Gulf of Mexico from inshore waters to 50 fm [fathoms]” (https://www.gsmfc.org/seamap-gomrs.php). (A quick note on the Texas Closure. In order to ­protect young brown shrimp and help ensure that the shrimp harvest is more mature and hence more commercially valuable, the Texas shrimp fishery is closed annually between May 15 and July 17.)

On the first leg (June 7 to 20) of the Survey, the Teacher at Sea aboard was Geoff Carlisle; on the second leg (June 27 to July 5, 2018), the Teacher at Sea aboard was Angela Hung.

At the time of writing we’re still on our way to the fish survey station; it’s a 30-hour steam out of Pascagoula. I look forward to reporting on our catches and the technology we’ll be using in a future post.

Personal Log

I flew into Gulfport, MS, from San Francisco, on the afternoon of Sunday, July 8, and was met at the airport by friendly and informed Field Party Chief Christina Stepongzi. As we crossed the bridge over the Pascagoula River and NOAA Ship Oregon II came into view, Chrissy said proudly: “There’s home.” On arrival, I got a quick tour of the vessel I’ll have the privilege of calling home for the next 12 days, and Chrissy introduced me around. The folks I met that afternoon (and since) were all just great: gracious and good humored, warm and welcoming. That first jovial bunch consisted of Chief Marine Engineer Joe Howe, Chief Steward Lydell Reed, and Junior Unlicensed Engineer Jack Steadfast. I got settled into my stateroom, and, jet-lagged and short on sleep, I turned in early.

I woke rested Sunday morning and went out onto the dock to look around. I’d brought a sketchbook with me (intending to keep a sketch-journal as both a pastime and an aid to learning), and, since I had a couple of hours to myself before a meeting at 1230 hours, I decided to try sketching the ship. I found a comfortable spot in the shade, and got busy. I’d hoped to sketch the ship from stem to stern, realizing I wouldn’t be able to take it all in once aboard. I planned to divide the ship in half and draw the halves on facing pages in my sketchbook. Stores arrived at 1000 hours, and I watched various preparations taking place fore and aft. I also helped carry a few bags of groceries aboard.

Working briefly in pencil and mostly in ink, I committed myself to certain shapes and proportions early on, and it soon became clear that I’d have to omit the bow and stern, focusing on the middle of the ship and making the best of things. Many of the objects, devices, and structural forms I was drawing were unfamiliar, and I looked forward to having a crew member explain what I’d been drawing later on.

It was an absorbing and thoroughly satisfying way of introducing myself to the ship, and I had the pleasure of meeting a few more members of the crew while I sketched. Skilled Fisherman Mike Conway introduced himself and very generously offered to grab me a fast-food lunch, since meals aboard weren’t being prepared yet. Arlene Beahm, the Second Cook, stopped by to say hello, as did First Assistant Engineer William Osborn. When the time came, I went aboard for the “Welcome Aboard” meeting, an orientation to the ship and shipboard courtesies by Operations Officer Ryan Belcher. Thereafter we had a little time to ourselves, so I meandered about the ship, meeting fisheries biologist Alonzo Hamilton in the galley. He kindly answered my questions about the version of the ship I’d sketched in the morning. (What were the white cylinders with domed tops amidships? Satellite antennas. What where the propeller-like forms forward of them, above the bridge? Radar.) We embarked at 1400 hours, and I up went to the flying bridge (i.e., the open deck above the bridge) to watch our passage down and out the mouth of the Pascagoula River and into the Gulf of Mexico.

I got good looks at some Laughing Gulls and some Terns (that I’ll need to ID later), and watched a shrimp trawler working next to the channel behind Petit Bois and Horn Islands.

Once we were in the Gulf proper, we were joined for a while by some Bottlenose Dolphins. An hour or two later, as I sat astern watching the sun set, I caught sight of a pair of Frigatebirds, high above the ship, their stunning forked tails trailing behind them. I’d never seen one, let alone two, and I didn’t sketch them or take a photograph of them. But you know I’ll remember them.

Did You Know?

Magnificent Frigatebirds don’t dive after fish. They skim themfrom the surface or chase after other birds, stealing their catches.
