This dataset comprises of hydrographic data from the Thwaites-Amundsen Regional Survey and Network (TARSAN) Integrating Atmosphere-Ice-Ocean Processes affecting the Sub-Ice-Shelf Environment project. CTD and glider data have been collected across a number of RV/IB Nathaniel B Palmer cruises in the Amundsen Sea during austral summer since 2018. The CTD data include conductivity (salinity), temperature and depth alongside auxiliary data including oxygen, fluorescence, transmission and PAR. Seagliders collected CTD, oxygen, fluorescence, PAR and microstructure data. The CTD data support data collected by gliders, ship-based surveys and autonomous underwater vehicles (AUVs). The data were collected to help identify how variations in oceanic conditions may influence the behaviour and stability of ice shelves in the region. The data were collected under the NERC grant NE/S006591/1 and in collaboration with the National Science Foundation in the United States.
