Microcat, current meter and ADCP data from moorings of the Deep Western Boundary Current array (Irminger Sea) as part of UK OSNAP (Overturning in the Subpolar North Atlantic Programme).

UK OSNAP (Overturning in the subpolar North Atlantic Programme) is a NERC Large Grant (2013-2018) and forms part of the international OSNAP array put in place to measure the full depth, basin-wide overturning circulation and associate transport of heat and freshwater. The array consists of a series of vertical moorings in the boundaries of the subpolar basins, supplemented by glider missions over shallow topography and floats (RAFOS floats to track the pathways of the overflow waters, and profiling floats to provide temperature and salinity information in the interior basins). This dataset has data from the first two year long deployments (2014 to 2016) of the Deep Western Boundary Current Array in the Irminger Sea, operated by UK OSNAP. The 5 moorings were deployed on cruise KN221-03 (2014), serviced on cruise PE400 (2015), recovered on DY054 (2016). The data sets are timeseries of pressure, temperature, salinity and currents and have been fully processed, calibrated and quality controlled.
