Science and Technology Log
NOAA Ship Pisces will conduct a survey of reef fish located on the U.S. continental shelf and shelf-edge of the Gulf of Mexico (GOM) from April 19 through June 22, 2022 (we are doing the last leg of the survey). 536 sites have been selected to be sampled with Spherical/Satellite array, bandit reels, and CTD during daylight hours and mapping at night.
CTD casts will be conducted twice a day. CTD stands for conductivity (ability to pass an electrical current), temperature, and depth and it is an instrument that measures just that. The CTD is the key to understanding the physics, chemistry, and biology of the water column. The CTD will also collect water for eDNA (Environmental DNA) sampling. Organisms leave traces of their DNA in their environment (e.g. hair, skin, feces) and from that, scientists can run genetic tests to determine what species are present in a given area.
Camera operations will utilize three Spherical/Satellite camera arrays. The cameras are baited and sit on the seafloor for 30 minutes. During the soak, the cameras capture footage of the biodiversity. Scientists use the footage to complete a stock assessment analysis. That data combined with other research helps scientists estimate the abundance of fish populations.
Bandit reels (basically industrial fishing poles) are deployed after cameras are retrieved. The bandit reels are set up like longlines. The line sits vertically in the water column. When the weighed end of the line reaches the bottom, a surface float is attached to the line. Ten baited hooks are evenly spaced on the bottom 20-30 ft. of the line. All fish captured on the bandit reels are identified, measured, weighed, and have the sex and maturity determined. Select species will have otoliths (ear bones) and gonads collected for age and reproductive research.
Bathymetric mapping (basically 3D mapping of the seafloor) will be conducted in and around selected sites at night with the EM 2040 sonar. Sonar emits sound pulses and detects their return after being reflected. Science is cool. A CTD cast will be conducted to obtain speed-of-sound for proper processing of data.
I was dropped off at my hotel at around 8 PM on Tuesday and could see the ship from the road. It sinks in. (NOT THE SHIP! – This had me laughing out loud.) This is actually happening. Suddenly there’s no time for checking in; I headed straight to the wharf, luggage in tow. Completely awestruck, like a giddy school girl, I proceed to walk up and down the length of the boat numerous times taking an embarrassing number of photos. The crew is just staring at me, I’m sure getting a kick out of this crazy tourist. A lovely gentleman (also geeked about the boat) leaned in, “cool boat, huh?”… I’M GOING ON THAT BOAT THURSDAY. Good lord, Jordan, be cool. I basically screamed in his face. He was the sweetest, and a teacher himself. “I know the trip is going to be everything you wanted.” I melt. Gee thanks, Pat.
Our departure was delayed a few hours, which gave me some time settle in and awkwardly roam the ship. This thing is massive (compared to what I know). I believe it has seven levels. My attempts to open and close doors quickly became a comedy act for any spectators. I was introduced to my roommates at 6 AM. Ain’t nobody trying to chit-chat at 6 AM. I share a stateroom with Amanda Ravas, NOAA Fisheries Biologist, and Caroline Hornfeck, graduate student at the University of West Florida. Caroline is collecting water for eDNA sampling. They are around my age (or at least I’d like to think so), and have been so kind and helpful. It is their first time on Pisces as well, but each are experienced and very knowledgeable. They’ve made me feel right at home, and I feel are going to be a major part of my experience out at sea. Women in science – go team!
Operations Officer (NOAA Corps), LT Christopher Duffy, was so kind as to take me under his wing and invite me to the bridge (control room) to observe departure. This was so cool. Navigation is quite the operation. I guess now that I’ve seen it, duh, this boat is massive and the port was so busy with vessels of all sizes. Seven NOAA officers worked together to get us underway safely. Lots of standing on watch and communication involved. They were constantly shouting commands and numbers, and repeating. All confirmed communication was acknowledged with a “very well.” I found this amusing. One of my favorite lines heard while observing was, “There’s a pleasure boat on the port quarter.” “Very well.”
I will now start saying “very well” in my everyday life.
Last mention for now – I haven’t been seasick (so far)! Those that know me well know that is a major accomplishment for me. (As if I had say in the matter).
I am so happy to be here and to have the opportunity to learn from all of the crew (in every department). I am already so impressed by each of them.
Did You Know?
Well most of us do know that water and electricity make a dangerous pair; but, did you know that it’s not water itself that conducts the electricity? It’s the minerals and such dissolved in it. The saltier the water, the more electricity it conducts. Pure water is actually an excellent insulator and does not conduct electricity, but you will never find pure water in nature. Whoa. I went down a rabbit hole with conductivity.
Also random, but kind of fun, the NOAA Teacher at Sea Program started in 1990, the year I was born. NOAA Ship Pisces was commissioned in 2009, the year I graduated high school.

Exciting! Looking forward to following your adventure, Jordan!
I look forward to following- I’m an 8th grade math teacher and my nephew, Lee is NOAA crew on the boat.
