This data set was collected from the first Saildrone Antarctic Circumnavigation. A fleet of 3 Saildrone unmanned surface vehicles (USVs) were launched from Bluff, New Zealand on January 19, 2019.
One USV (SD-1020) was equipped with a pCO2 sensor suite (ASVCO2, developed by NOAA PMEL) and a 300 kHz ADCP. The two others USVs (SD-1022 and SD-1023) are equipped with scientific echosounders (SIMRAD EK80 WBT mini). All three USVs also carry the standard Saildrone atmospheric and oceanographic sensor suite.
SD-1020 was the first of the USVs to complete the circumnavigation and was recovered in New Zealand on August 3, 2019 after 196 days and over 22,000 kilometers. SD-1022 and SD-1023 were damaged in the first 24 hours in winds gusting above 50 knots and 20 ft waves and had to return to New Zealand for servicing. They were relaunched on May 10, 2019.
Scientific objectives for SD-1020 included studying air-sea flux, ocean acidification, and meteorological data collection for use in weather forecasting and ecosystem modeling. SD-1022 and SD-1023's science objectives focused on krill and biomass studies.
This Antarctic circumnavigation data set contains saildrone platform telemetry and near-surface observational data at 1 minute to 1 day resolution in netCDF format, and ADCP current data binned temporally at 5 minute resolution.
