AXCTD and AXBT Profiles from the Amundsen Sea Data DOI: https://doi.org/10.15784/601894 Cite as Greenbaum, J. (2025) "AXCTD and AXBT Profiles from the Amundsen Sea" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/601894. Abstract This dataset contains ocean profile measurements from Airborne Expendable Conductivity, Temperature, Depth (AXCTD) and Airborne Expendable Bathy-Thermograph (AXBT) sensors deployed by helicopter and from the RV Araon research icebreaker. AXCTDs were deployed around the Thwaites Glacier Tongue while the AXBTs were deployed near the Dotson Ice Shelf and along a northbound transect at the end of the field season. The profiles were acquired in February 2022.
