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, moorings were deployed across the boundaries of the Labrador Sea, Irminger Sea, Iceland Basin, and eastern subpolar North Atlantic. The OSNAP West array consists of eight moorings spanning from the west Greenland shelf to the base of the continental slope. The three shelf moorings are bottom tripods, while the five offshore moorings are tall moorings extending to 100 m depth. Each of the moorings contained a weak-link extension to obtain hydrographic measurements 50 m below the surface. Velocity was measured using a combination of Aquadopps and acoustic Doppler current profilers (ADCPs), and the pressure, temperature, and salinity were measured using MicroCATs. The time ...
