Overturning in the Subpolar North Atlantic Program (OSNAP) moored current meter, temperature, conductivity, salinity, and pressure data collected on subsurface moorings M1, M2, M3, and M4 between June 2018 and August 2020

Abstract

As part of the Overturning in the Subpolar North Atlantic Program (OSNAP), four mooring arrays were deployed in the Greenland Deep Western Boundary Current (GDWBC) located off the east coast of Greenland, in the Irminger Sea. The array consisted of four subsurface moorings M1, M2, M3, and M4, containing 30 MicroCATs and 18 Aquadopp Current Meters, and deployed between June 2018 and August 2020. The data sets are timeseries of temperature, conductivity, pressure, and salinity recorded at 15-minute intervals and current meter data collected at 30-minute intervals. The depths of the moorings were 2086 meters, 2436 meters, 2557 meters, and 2984 meters respectively. The data have been fully processed, calibrated, and quality controlled.
