Dominic Hodgson is a Quaternary Scientist specialising in high latitude climate and environmental change. He leads the Quaternary Sediments group in the ‘Chemistry and Past Climate’ programme at the British Antarctic Survey. The programme uses ice cores, as well as polar marine and lake sediment cores and terrestrial records, to investigate how the different parts of the Earth System have interacted to produce the large climate changes that occurred naturally in the past. By understanding these changes we are able to better constrain predictions of future change. Recent career highlights include extending the IGBP Americas’ Pole-Equator-Pole palaeoclimate transect through the Antarctic Peninsula to the Pole, improving estimates of ice mass loss from Antarctica using records of relative sea level change, reconstructing the Holocene history of Antarctic Peninsula ice shelves, documenting climate history from lakes that have survived through glacial cycles, working on a recently emerged subglacial lake and developing technologies to sample a subglacial lake beneath the West Antarctic Ice Sheet.
