Raw multibeam bathymetry data collected around Southern Thule, part of the South Sandwich Island chain in the Southern Ocean on board the R/V Akademik Tryoshnikov during the austral summer of 2016/2017 as part of the Antarctic Circumnavigation Expedition (ACE).

Dataset abstract

An ELAC Nautik 3020 multibeam echo sounder with a 20 kHz transducer mounted on the hull of the R/V Akademik Tryoshnikov, was used to collect multibeam bathymetry data during the Antarctic Circumnavigation Expedition (ACE). This particular dataset was collected around Southern Thule, part of the South Sandwich Island chain in the Southern Ocean in the austral summer of 2016/2017.

Bathymetry data were used live during the cruise to look for suitable locations where benthic trawling and remotely-operated vehicle deployments could take place, rather than to undertake specific bathymetric surveys.

This raw dataset is provided without calibration information for the surface sound velocity or instrumentation itself and should be used with due caution.
