Journal of Glaciology, 2022 Mass loss from ice shelves is a strong control on grounding-line dynamics. Here we investigate how calving and submarine melt parameterizations affect steady-state grounding-line positions and their stability.

Simulated melt rates for the Totten and Dalton ice shelves [PDF]
Ocean Science, 2014 The Totten Glacier is rapidly losing mass. It has been suggested that this mass loss is driven by changes in oceanic forcing; however, the details of the ice–ocean interaction are unknown.

Ice-Shelf Melting Around Antarctica [PDF]
Science, 2013 Major Meltdown The ice shelves and floating ice tongues that surround Antarctica cover more than 1.5 million square kilometers—approximately the size of the entire Greenland Ice Sheet. Conventional wisdom has held that ice shelves around Antarctica lose mass mostly by iceberg calving, but recently it has become increasingly clear

Ice-shelf – ocean interactions at Fimbul Ice Shelf, Antarctica from oxygen isotope ratio measurements [PDF]
Ocean Science, 2008 Melt water from the floating ice shelves at the margins of the southeastern Weddell Sea makes a significant contribution to the fresh water budget of the region.

Nature Communications, 2017 The formation mechanisms of ice-shelf channels remain poorly understood. Here, using ice-penetrating radar data, the authors propose that ice-shelf channel morphology in the Roi Baudouin Ice Shelf, East Antarctica, is seeded by esker ridges, indenting ...

On the interpretation of ice-shelf flexure measurements [PDF]
Journal of Glaciology, 2017 ABSTRACTTidal flexure in ice shelf grounding zones has been used extensively in the past to determine grounding line position and ice properties. Although the rheology of ice is viscoelastic at tidal loading frequencies, most modelling studies have assumed some form of linear elastic beam approximation to match observed flexure profiles.

Nanomaterials Trigger Functional Anti‐Tumoral Responses in Primary Human Immune Cells
Advanced Science, EarlyView.Nanoparticles are used to improve immunomodulatory therapies, but the impact of drug‐free nanomaterials on the immune system remains unknown. Screening common biomedical nanoparticles (NPs) reveals that PLGA NPs enhanced NK cell anti‐tumoral activity and transcriptional activation in human NK and pan T cells.

The speedup of Pine Island Ice Shelf between 2017 and 2020: revaluating the importance of ice damage
Journal of Glaciology, 2023 From 2017 to 2020, three significant calving events took place on Pine Island Glacier, West Antarctica. Ice-shelf velocities changed over this period and the calving events have been suggested as possible drivers.

Catastrophic ice-shelf break-up by an ice-shelf-fragment-capsize mechanism [PDF]
Journal of Glaciology, 2003 AbstractTwo disintegration events leading to the loss of Larsen A and B ice shelves, Antarctic Peninsula, in 1995 and 2002, respectively, proceeded with extreme rapidity (order of several days) and reduced an extensive, seemingly integrated ice shelf to ajumble of small fragments.
