DISTRIBUTED TEMPERATURE SENSING OF ANTARCTIC
ICE SHELVES AND CAVITIES
(National Science Foundation)

Beginning with a collaborative project with New York University and the Ohio State University to measure sub-ice shelf ocean temperatures and ocean dynamics, this work has now been incorporated into the extensive monitoring efforts of the Thwaites Glacier in west Antarctica.  The International Thwaites Glacier Collaboration a joint effort supported by the US NSF and the UK NERC seeks to understand one of the most unstable glaciers in Antarctica.  To date, almost three years of continuous ocean and ice shelf monitoring on the AMIGOS-3 systems has been supported by UNR resulting in more than 20 million records of temperature, salinity, pressure and current beneath the ice shelf. Recent results ( Dotto_et_al (2022), agu_2023_v3 published at the 2023 AGU meeting )document ocean warming as well as daily/annual fluctuations beneath the ice shelf.
