Oxygen in the North Atlantic: Variability and Measurement
The Atlantic Meridional Overturning Circulation (AMOC) is a critical component of global water mass circulation, as the North Atlantic is one of the main locations where surface water sinks to the bottom of the ocean. This summer, I had the opportunity to study the oxygen and other water properties of the North Atlantic, both in models at the Geophysical Fluid Dynamics Laboratory (GFDL) and at sea on the German research vessel RV Meteor. In the lab, I compiled time series from previously measured data from this area to examine annual and decadal variability in water mass properties. On board the ship, I was on the team responsible for measuring oxygen in water samples taken at various points in the water column. The oxygen I measured in samples was used to calibrate electronically measured data ultimately destined for further research and online data repositories such as those that I used while in the lab. At the same time, I learned both about these water masses as well as how to carry out experimental oceanography on board a ship.
