Dating West Antarctic ice sheet collapse using molecular sequence data (Old ID 24850)
Role
Principal Investigator
Description
This project aims to investigate the past stability and configuration of the West Antarctic Ice Sheet by examining genomic signatures in present day bottom-dwelling Antarctic marine animals. By employing this novel biological approach to address a key question for physical scientists, this project will provide an independent test of the hypothesis that the West Antarctic Ice Sheet collapsed during the most recent interglacial and formed a transAntarctic seaway. Expected project outcomes include increased resolution of the most recent collapse of the West Antarctic Ice Sheet. This should provide significant benefits in predicting future collapse and its impact on sea level rise which is a key uncertainty resulting from climate change.
