| Summary: | This dataset contains the velocity profiles in the Thwaites Gyre region collected by the shipborne Acoustic Doppler Current Profiler (ADCP) onboard RV Nathaniel B Palmer in 2019 under the project Thwaites-Amundsen Regional Survey and Network Integrating Atmosphere-Ice-Ocean Processes (TARSAN). Ocean current velocities over the upper 980 m of the water column were obtained using a 75 kHz Ocean Surveyor (OS75) and a 38 kHz Ocean Surveyor (OS38) shipboard Acoustic Doppler Current Profiler (sADCP). Common Ocean Data Access System (CODAS) processing has been run to generate the NetCDF files. The authors made additional quality control including, 1. removing data with velocity values higher than 0.6 m/s and other obviousoutliners, and2.removing data below 400 m for OS75 and data below 760 m for OS38 as thelast several levels in the velocity profiles are believed to be potentially affected by the water turbidity and bubbles passing below the sADCP etc. The data are stored in .txt formatand .mat MATLAB format. This dataset is supplementary to The Cryosphere paper "Reversal of ocean gyres near ice shelves in the Amundsen Sea caused by the interaction of sea ice and wind". The complete shipborne ADCP data are available at https://www.bodc.ac.uk/. In addition to the funding sources listed for this dataset, Y. Z. is also supported by the China Scholarship Council and the University of East Anglia.
