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, 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 10 moorings spanning from the west Greenland shelf to the base of the continental slope. The 5 shelf moorings are bottom tripods, while the five offshore moorings are tall moorings. The tripod 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 period of the first deployment of the array was September 2018 to July 2020. All of the data have been calibrated, processed, and quality controlled.
