2018-2019 USAP Field Season
Response of the Antarctic ice sheet to the last great global warming
Dr. Brenda Hall
Supporting Stations: McMurdo Station
The response of the Antarctic Ice Sheet to past episodes of rapidly warming climate can be understood through glacial geologic data. Researchers will use a combination of glacial geologic mapping and radiocarbon dating of algal deposits enclosed in recessional moraines at the glacial headlands of the southern Royal Society Range. They aim to reconstruct the evolution of the Antarctic Ice Sheet during the massive warming of the last glacial/interglacial transition and inform understanding of future ice-sheet response to global warming.
Field Season Overview
A four-person team will travel from McMurdo Station by helicopter to the Royal Society Range where they will camp in Scott tents at three different locations for six weeks. They will make some day trips to other sites by helicopter. The research team's work will consist of mapping and collecting algae and rock samples for radiocarbon and surface exposure age dating. Samples will be shipped back to McMurdo Station periodically during the field season for shipment to the research team's home institution.
