Dataset Overview | National Centers for Environmental Information (NCEI)

Gulf Stream 2019 Near-Real-Time Mission Data (ocean and atmosphere) collected from Saildrone 1021 in North Atlantic Ocean from 2019-01-30 to 2019-02-26 (NCEI Accession 0212656)

These data are reported from a Saildrone unmanned surface vehicle (USV), with limited initial quality control. Remote participants directed the Saildrone to pursue waypoints along a trajectory from Newport, Rhode Island to the Gulf Stream, with the objective of repeatedly sampling the cross-Gulf Stream gradients, along the length of the current. The Saildrone left Newport on 30 January 2019 and collected data until 26 February 2019. The mission ended prematurely after the USV sustained mission-compromising damage in 12+ meter significant wave heights. The USV was safely recovered in Bermuda. The data provided here are from the meteorological instruments mounted on the hull and wing (e.g., air temperature, barometric pressure, wind speed/direction) and the oceanographic instruments that sample below the sea surface (e.g., temperature, salinity, oxygen, pCO2, pH).
