(2026) "Turbulence dissipation rates under sea ice from a free-falling microstructure profiler in the western Weddell Sea" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/None. Abstract This data set contains vertical profiles of ocean temperature, salinity, turbulence dissipation rates and bio-optical properties, obtained from the sea ice in the western Weddell Sea during an expedition with the research icebreaker RV Polarstern, February to April 2026. Data were obtained with a battery powered, internal recording free-falling VMP250-IR (Rockland Scientific Inc., VMP hereafter), deployed at helicopter stations and ice stations from the ship, down to depths of either 300~m or 500~m.
