Extending the record of ice-sheet change in Antarctica from historical archives

Narrowing uncertainties in the future contribution of the Antarctic Ice Sheet to sea-level rise is of scientific and societal importance. These uncertainties can be reduced by constraining how the ice sheet has changed over recent decades. Most modern observational records of ice-sheet change are short and begin in ~2000, and historical datasets that can be used to extend the record many decades further back in time have largely been neglected. This fellowship will combine reconnaissance satellite imagery (1960s and 1970s), aerial photography (1940s) and mapping from early explorers (19th and 20th centuries) to constrain longer-term trends and inform sea-level projections.
