Cruise description

This cruise went really well. Despite having only two weeks to do the cruise we managed to do everything we were planning to, and more. It really, really helped that the crew of the Tully was ready for us to start loading the morning of February 8th, before the official start of the cruise. This allowed us to leave on the first evening of the allocated ship time. Starting to load in the morning also helped in that groups loaded their gear one after the other, instead of everything coming on board at once. The weather was a big factor too in the success of this cruise. We had to cancel a few casts on the outbound leg, but we were able to revisit those stations on the way back, and all in all the weather was really decent for a February cruise. Another factor for success was the smaller demands on wire time than usual. No trace metal or primary productivity samples were collected so less time had to be spent at each station. Because of this factor we were able to recover a malfunctioning Glider for Woods Hole Oceanographic Institution.
The regular sampling done during this cruise was completed using a CTD, a Rosette, and the Bongos
. For further details see 2016-01_cruise_report.pdf in the Documents section.
