EUROFLEETS ANTSSS (Antarctic ice Sheet Stability from continental Slope process investigation)

Complementary with the ODYSSEA project funded by PNRA, ANTSSS aimed at finding evidence for Late Pleistocene sedimentary signatures of major changes in the extent of grounded, marine based ice sheets in the Ross Sea, as preserved in slope/ rise drift deposits by means of seismic and oceanographic data. During the 2017 expedition, OGS Explora collected over 450 km of Single Channel Seismics (SCS), 1575 km2 of bathymetry, >500 km of sub-bottom, and oceanographic data, including Conductivity Temperature Depth (CTD), Acoustic Doppler Current Profiler (ADCP), Lowered-ADCP, Expendable Bathythermograph (XBT) and turbidity data. Part of the seismic data have been initially published in Gales et al. (2021) Role of dense shelf water in the development of Antarctic submarine canyon morphology.
