Conductivity-Temperature-Depth (CTD) data as part of the OSNAP (Overturning in the Subpolar North Atlantic Program), from 2020 on the R/V Neil Armstrong

Abstract

The Overturning of the Subpolar North Atlantic Program (OSNAP) is an effort to determine the strength of the meridional overturning circulation and associated heat and freshwater fluxes in the subpolar North Atlantic. It is a collaborative program with scientists from the U.S., U.K., Netherlands, Germany, France, Canada, and China. Together, a series of hydrographic surveys and mooring deployments have been completed across the boundaries of the Labrador Sea, Irminger Sea, Iceland Basin, and eastern subpolar North Atlantic.
