MicroCAT and current meter data from moorings of the Eastern Boundary array (Rockall Trough), funded by CLASS (Climate Linked Atlantic Sector Science), as a continuation of UK-OSNAP (Overturning in the Subpolar North Atlantic Programme) (2018-2020)

CLASS (Climate Linked Atlantic Sector Science) is a six-year National Capability programme led by the National Oceanography Centre and in collaboration with The Scottish Association for Marine Science, Plymouth Marine Laboratory, Marine Biological Association, and the Sea Mammal Research Unit. CLASS runs from 2018 to 2024. CLASS underpins the UK contribution to the international OSNAP (Overturning in the subpolar North Atlantic Programme) array put in place to measure the full depth, basin-wide overturning circulation and associate transport of heat and freshwater between Canada, Greenland and Scotland. The international OSNAP array consists of a series of vertical moorings in the boundaries of the subpolar basins, glider missions over shallow topography and profiling floats to provide temperature and salinity information in the interior basins. The data sets are timeseries of pressure, temperature, salinity and currents of the CLASS Rockall Trough Mooring array (RTWB1, RTWB2, RTEB1) from 2018 to 2020, delayed time processed and quality controlled.
