Abstract
The University of Miami's OSNAP (Overturning in the subpolar North Atlantic Program) is an NSF funded project that is part of the international OSNAP array put in place to measure the full depth, basin-wide overturning circulation and associated transport of heat and freshwater (www.o-snap.org). The UM array consists of a series of vertical sub-surface moorings deployed along the eastern slope of the Reykjanes Ridge and across the Iceland Basin near 58°N. This dataset contains data from the first four year-long deployments (2014 to 2018) of the Deep Western Boundary Current Array in the Iceland Basin. The data sets are time series of pressure, temperature, salinity and currents and have been fully processed, calibrated and quality controlled.
