lowering the CTD Rossette into the water
(Friday, May 17) Mooring operations commenced at 7 am under the leadership of Chief Scientist Jim Singer (SAIC). They worked hard all day under the hot sun, pulling up moorings that had been deployed a year ago. Each mooring has an array of instruments measuring temperature, conductivity, pressure and currents, at different depths in the water column. Everything went smoothly until we arrived at the last mooring of the day, M3. It had been dragged 3500 meters from its deployment position. This meant we had to do a little ‘search and recovery’ session, which put us behind schedule for the nightly CTD work. Once mooring M3 popped to the surface, we realized that the wire had been cut right above the bottom flotation, which meant most of the instruments were lost. With the amount of shrimping boats in this region, it probably got caught in someone’s net and the wire cut to save their net. Once mooring M3 was securely on board, we headed for our first CTD station. It was another long night of CTD work, and despite the late start, we managed to complete three of the six planned casts.

On our way back we were privy to dolphins, acoustic guitar music (courtesy Kendall Klay), a starlit night with satellite watching on the bow of the ship. It was a great trip, with an eclectic mix of interesting people. And last, but by no means least, the food that chef Alex Forsythe prepared for us each day was delightful.
