Seafloor ploughmarks on the mid-Norwegian continental shelf reveal iceberg trajectories during the last glacial period
… linear to curvilinear depressions interpreted as iceberg ploughmarks were mapped across the mid-Norwegian continental shelf using high-resolution swath bathymetry data. The orientation and morphology of each iceberg ploughmark was calculated and analysed, with features being up to 30 km long and …

Insights from geodynamic models into ice flow, mantle magmatism, and their interactions
… I model how the deglaciation of the Yellowstone ice cap caused a reduction in mantle pressures and enhanced melting 19-fold. I predict the additional melting segregates a globally-significant mass of CO2, potentially playing a role in positive feedbacks between deglaciation and climate. I suggest …

Iceberg-keel ploughmarks on the seafloor of Antarctic continental shelves and the North Falkland Basin: implications for palaeo-glaciology
The use of iceberg-keel ploughmarks as proxy indicators of past and present iceberg morphology, keel depth and drift direction has seldom been approached in the southern hemisphere. Using high-resolution multi-beam swath bathymetry of the mid-shelf Pine Island Trough and outermost Weddell Sea shelf …
