Saildrone Unmanned Surface Vehicle (USV)

Platform IDs



This data was collected in the western Atlantic Ocean in the vicinity of Cabo Verde and the Canary Islands and in the Mediterranean Sea during the first Saildrone Atlantic to Mediterranean (ATL2MED) mission between October 18, 2019, and July 17, 2020.

In addition to the standard Saildrone sensor suite, one Saildrone unmanned surface vehicle (USV), SD 1030, was equipped with a pCO2 sensor suite (ASVCO2, developed by NOAA PMEL) and 300 kHz ADCP. The other Saildrone USV, SD 1053, was equipped with a scientific echo sounder (SIMRAD EK80 WBT mini).

The scientific objectives during the ATL2MED mission include an eddy survey near Cabo Verde (Phase 1) led by GEOMAR and a cross-calibration of CO2 measurements at nine fixed ocean stations (Phase 2) led by ICOS: CVOO (Cabo Verde), ESTOC (Gran Canaria), LION (France), ANTARES (France), DYFAMED (France), W1M3A (Italy), E2M3A (Italy), PALOMA (Italy), and Miramare (Italy).

Mission highlights include the first autonomous passage of the Strait of Gibraltar, monitoring oceanographic conditions in the area of a tagged sea turtle navigating near the strong anticyclonic eddy south of Ibiza, a saildrone-glider comparison study along the Nice-Calvi Line, and a volcanic impact survey around the Aeolian Islands.

This data set contains Saildrone platform telemetry and near-surface observational data at 1-minute to 1-day resolution in NetCDF format.
