Theoretical stability of ice shelf basal crevasses with a vertical temperature profile
Published 2024-01-01“…Using HFB instead of Zero Stress for cracks in an ice-sheet model would substantially enlarge the predicted fracture depth, reduce the threshold rifting stress and potentially increase the projected rate of ice shelf mass loss.…”

Mechanisms for upstream migration of firn aquifer drainage: preliminary observations from Helheim Glacier, Greenland
Published 2025-01-01“…Surface meltwater can influence subglacial hydrology and ice dynamics if it reaches ice sheet's base. Firn aquifers store meltwater and drain into wide crevasses marking the aquifer's downstream boundary, indicating water from firn aquifers can drive hydrofracture to establish surface-to-bed hydraulic connections at inland locations. …”

Wave erosion, frontal bending, and calving at Ross Ice Shelf
Published 2025-01-01“…<p>Ice shelf calving constitutes roughly half of the total mass loss from the Antarctic ice sheet. Although much attention is paid to calving of giant tabular icebergs, these events are relatively rare. …”

Ocean warming, icebergs, and productivity in the Gulf of Alaska during the Last Interglacial
Published 2025-02-01“…The Pacific Ocean is an important region for carbon storage, yet the past ocean–climate interactions are relatively underexplored in explaining glacial/interglacial climate variability during the late Pleistocene re-expansion of the Cordilleran Ice Sheet (CIS). We analysed marine sediment samples from IODP 341 Expedition Site U1418 in the Gulf of Alaska (GOA) using marine and terrestrial biomarkers to study the periodicity of glacial–interglacial cycles over the last 500 thousand years and reconstruct the North Pacific oceanography and marine productivity. …”

Lacustrine sedimentation patterns at the Northern Antarctic Peninsula and surroundings as a response to late Holocene and Modern Climate changes
Published 2024-12-01“…Abstract The Northern Antarctic Peninsula (NAP) and the West Antarctic Ice Sheet (WAIS) are likely to respond rapidly to climate changes by increasing the collapse of peripheral ice shelves and the number of days above 0 °C. …”

Ice-proximal sea ice reconstruction in the Powell Basin, Antarctica, since the Last Interglacial
Published 2025-01-01“…Finally, despite similar findings between the proxy and model data, notable differences persist between both interglacials – emphasizing the necessity for different Antarctic ice sheet configurations to be employed and more robust paleoclimate data to enhance climate model performance close to the Antarctic continental margin.…”

The contribution of hydroisostasy to modern changes in sea level and vertical displacements of the solid surface of the Earth in the Far Eastern seas
Published 2024-12-01“…The melting of large ice sheets in areas far from the centers of glaciation, such as the Far Eastern seas, caused the loading of the seabed with a 120 m layer of water – hydroisostasy – which caused vertical displacements of the seafloor and coastal areas. …”
