About this Cruise

This month-long cruise aboard the NOAA Ship Oscar Elton Sette brings together six diverse teams to survey fish populations using non-catch methods. Traditionally, fish populations have been assessed by catching fish, visiting fish markets and interviewing fishermen. Chief Scientist Scott Ferguson hopes to support Guam and the CNMI in monitoring their natural resources using non-extractive methods. The ship will also use multibeam sonar to map areas that are important fishery resources hopefully to include Galvez Bank, offshore slopes near Rota, and the banks of Farallon de Medinilla.

The survey methods include BotCams and BRUVs, two systems that put baited cameras on the bottom, and a TOAD which is a camera towed near the seafloor . An Autonomous Underwater Vehicle will travel on its own via computer programming and bring back photographs and video. Additionally, acoustic methods will be used to survey fish in the water column.

This expedition brings together scientists from NOAA’s Pacific Islands Fisheries Science Center and Northwest Fisheries Science Center, as well as the University of Hawaii’s Joint Institute for Marine and Atmospheric Research, the University of Guam Marine Lab, and Woods Hole Oceanographic Institution.

YouTube: AUV, BRUVs and BotCams

Mike Marino, an officer on the ship, made a great little movie showing the work done during the first two weeks of this expedition.

Hi Ms. Tatreau, I would ask if your having fun but I already know that you are. I saw the video and it was interesting. Was that a research that you were doing? I hope you bring back something because your trip looks really cool and it would be cool if we got to see something interesting that you found.

Hi Can,
I’m not sure what video you watched. If you watched this one from YouTube, it showed the types of cameras we used doing the fish surveys. What will I bring back? Lots of pictures.

Really nice video on YouTube. It's amazing how much you guys have accomplished so far. Those cameras and devices really look expensive, and yeah the prices were on the blog before. You guys are doing a great job and working even at nights.

Last night, we stopped mapping and used the towed camera to look at the seafloor we had mapped. I love watching real time video but I was falling asleep on my feet. They shot video with the towed camera for almost 6 hours and I slept through most of it.

The video was amazing. I am glad I was able to experience a sneak peak of what your expedition is like. The part that really caught my attention was when the camera was on the seafloor with bait attached to it. I thought that was a clever idea because by doing that you can actually see the variety of fish they have at any place you do that. Toby-5

Hi Toby,
The video footage from the BRUVs has been really fun. We saw lots of reef fishes and some real attention grabbers like the big snappers, barracudas, sharks, rays and eels. Yesterday, a turtle visited the bait bag.
