This record describes the EM-APEX Floats data from the Marine National Facility (MNF) RV Investigator voyage IN2023_V07, titled "SWOT-ACC: smaller scales of the Antarctic Circumpolar Current in a meander south of Tasmania." The voyage took place between November 15, 2023 and December 20, 2023 (AEST), departing from Hobart and returning to Hobart. Two EM-APEX floats were deployed to measure high-resolution profiles of temperature, salinity, pressure, and horizontal velocity in the Antarctic Circumpolar Current. These observations provide critical subsurface data to link small-scale variability in sea surface height observed by the SWOT satellite with underlying ocean circulation, eddy activity, and cross-front transport of heat and carbon. Tracking of the EM-APEX floats is available via the interactive map link, using hull numbers f10331 and f10317.
