This data set was collected during the first Saildrone Antarctic Circumnavigation. A Saildrone Explorer uncrewed surface vehicle (USV) was launched from Bluff, New Zealand, on January 19, 2019.

SD-1020 was equipped with a pCO2 sensor suite (ASVCO2, developed by NOAA PMEL) and a 300 kHz ADCP in addition to the standard Saildrone Metocean sensor suite.

SD 1020 completed the circumnavigation and was recovered in New Zealand on August 3, 2019, after 196 days at sea, sailing more than 11,000 nautical miles. Scientific objectives for SD 1020 included studying air-sea flux, ocean acidification, and meteorological data collection for use in weather forecasting and ecosystem modeling. 

This data set contains Saildrone platform telemetry and near-surface observational data at 1-minute resolution in NetCDF format, and ADCP current data binned temporally at 5-minute resolution.
