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 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. 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 August 2016 to August 2018. The sampling
interval was 30 min for the Aquadopps, 1 hour for the ADCPs, and 15
min for the MicroCATs. All of the data have been calibrated,
processed, and quality controlled.
