Rob Larter is a marine geophysicist at British Antarctic Survey. Since 2004, his main research focus has been on late Quaternary ice sheet history, glacial geomorphology and glacial/glacial-marine processes. He also remains active in research on the tectonic and palaeoenvironmental history of Antarctica and the Southern Ocean through the Cenozoic era. Larter's specialties include the acquisition, processing and interpretation of seismic reflection, marine magnetic, swath bathymetry, and sidescan sonar data.

Larter is a lead principal investigator on the THOR project. He and his team will investigate sediments deposited in the seas near the Thwaites Glacier, and reconstruct past changes in environmental conditions and the glacier's response, adding context to projections of future change.
