Conductivity-Temperature-Depth (CTD) data as part of the OSNAP (Overturning in the Subpolar North Atlantic Program), from 2014 on the R/V Knorr (KN221-03)

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, a series of hydrographic surveys and mooring deployments have been completed across the boundaries of the Labrador Sea, Irminger Sea, Iceland Basin, and eastern subpolar North Atlantic.

This submission contains CTD data from the Labrador Sea and Irminger Seas near southern Greenland from the KN221-03 research cruise in 2014. The primary purpose of this dataset is to aid in the calibration of moored instrumentation in the region associated with the OSNAP program. Each CTD file contains pressure-averaged data for one CTD station following the World Ocean Circulation Experiment (WOCE) format and quality specifications for CTD data. CTD sensors have been scaled with pre-cruise calibrations from their respective manufacturers. All CTD salinity measurements have been post-calibrated using bottle salinity measurements.
