Find out more about this below... In 2018 when we were on the RV Neil Armstrong we did the same research cruise to swap over deep-sea oceanographic moorings and calibrate instruments. We are only doing the eastern side of all of the moorings this year because collaborators and different scientists are on the Neil Armstrong completing the moorings from greenland toward iceland to fill in the gaps. This is the 3rd time I have done oxygen analysis on a research cruise, but this time I was in charge of packing, transporting, and sorting out all of the chemicals and equipment. It is pretty stressful because if you mess up mixing the chemicals or don't pack something it can re...
