These datasets are a part of the Southern Ocean Carbon and Heat Impact on Climate (SO-CHIC, https://www.sochic-h2020.eu/) project, and were collected during the field campaign in 2022.

Seaglider SG640 (SG640_20220110_SOCHIC.nc)

This dataset contains the temperature, salinity, dissolved oxygen, fluorescence, and backscatter profiles from a Seaglider (SG640), which was deployed at the Maud Rise seamount in the eastern part of the Weddell Sea from the 10th of January 2022, to the 7th of April 2022. These profiles are available at Level 2 (basic gridding) and Level 3 (despiked and interpolated).

Seaglider SG675 (SG675_20220123_SOCHIC.nc)

This dataset contains the temperature, salinity, dissolved oxygen, fluorescence, and backscatter profiles from a Seaglider (SG675), which was deployed at the Maud Rise seamount in the eastern part of the Weddell Sea from the 23rd of January 2022, to the 18th of June 2022. These profiles are available at Level 2 (basic gridding) and Level 3 (despiked and interpolated).

Sailbuoy Kringla (SB_20220110_SOCHIC.nc)

This dataset contains atmospheric and oceanic observations of wind speed, air and sea temperature, salinity, and currents. The Sailbuoy was deployed at the Maud Rise seamount in the eastern part of the Weddell Sea from the 10th of January 2022, and recovered on the 17th of June 2022. There was a brief period in March where she was recovered and repaired by Polarstern and subsequently re-deployed, losing around three days of data. The ADCP data were processed using Edholm, J. M.

Saildrone 1067 (SD-1067-NRT-data.nc)

This dataset contains atmospheric and oceanic observations of wind speed, air and sea temperature, relative humidity, short and longwave radiation, pCO2, dissolved oxygen, chlorophyll-a, salinity, and currents. The Saildrone was deployed in the Agulhas retroflection area in the Cape Cauldron from the 24th of August 2022 to the 22nd of November 2022.
