Rob is a geologist with a research background in Paleoclimate and Paleooceanography. He researches how geological evidence indicates that marine based portions of the Antarctic Ice Sheet behave in an unstable manner and retreat rapidly in response to abrupt climate and oceanic change; and how this is a key factor in improving estimates of Antarctic ice volume contribution to future sea-level rise. He also investigates the oceanic and global climate (including biotic) response to past loss of the Antarctic Ice Sheets and sea ice. In the Antarctic Science Platform, Rob will investigate these topics through analysis of sediment cores collected by international oceanographic cruises, as well as the NZ-led SWAIS2C project.
