This last ADEON cruise is beginning to wrap up, with our last CTD and net tow of the trip completed yesterday through last night in almost 3000 m of water. We moved to this deeper area further off of the continental shelf so the Jason crew could accomplish some engineering dives, sending the ROV Jason out to test equipment and techniques in a dive that lasted most of a day! It’s been really cool to hear about the Jason and watch the crew at work – getting the chance to look around at the sea floor through Jason’s cameras has definitely been a highlight of this trip!

We took advantage of being in this deep water to accomplish an ADEON tradition: decorating styrofoam cups to send down on a deep CTD. The pressure at thousand-meter depths squeezes the air out of the styrofoam and shrinks the cups, and our decorations with them. It’s always fun to break out some arts and crafts along with our science!
