Repeated large-scale retreat and advance of Totten Glacier indicated by inland bed erosion
Goodeve Assistant Professor Alan Aitken's SES Seminar Presentation, 23 June 2016
With changing climate, ice-sheet retreat and advance causes sea-level changes of metres to decametres magnitude, but large uncertainties limit our understanding of these. The contribution of the East Antarctic Ice-sheet (EAIS) to past sea-level change is particularly ill-defined, restricting our appreciation of potential change in the future. Several lines of evidence suggest possible collapse of the Totten Glacier catchment during past warm periods, most notably the Pliocene1-4, causing several meters of sea-level rise.
