DOI: 10.1002/2017gl072648
Abstract: Tabular iceberg calving and ice shelf retreat occurs after full-thickness fractures, known as rifts, propagate across an ice shelf. A quickly evolving rift signals a threat to the stability of Larsen C, the Antarctic Peninsula's… read more here.

Time-dependent freshwater input from ice shelves: impacts on Antarctic sea ice and the Southern Ocean in an Earth System Model†

DOI: 10.1002/2017gl075017
Abstract: Earth System Models do not reproduce the observed increase in Antarctic sea ice extent which may be due to the unrealistic representation of ice shelves. Here we investigate the response of sea ice to increasing… read more here.

DOI: 10.1017/jog.2019.101
Abstract: The stress balance within an ice shelf is key to the resistance, or buttressing, it can provide and in part controls the rate of ice discharge from the upstream ice sheet. Unconfined ice shelves are… read more here.

DOI: 10.1017/jog.2019.98
Abstract: Diurnal depth cycles of decimeter scale are observed in a supraglacial lake on the McMurdo Ice Shelf, Antarctica. We evaluate two possible causes: (1) tidal tilt of the ice shelf in response to the underlying… read more here.

DOI: 10.1017/jog.2025.10070
Abstract: Abstract Ice crystal fabrics can exert significant rheological control on ice sheets and ice shelves, potentially softening or hardening anisotropic ice by several orders of magnitude compared to isotropic ice. We introduce an anisotropic extension… read more here.

DOI: 10.1029/2024eo240407
Abstract: Spring blooms shade Antarctic ice shelves, causing them to melt 7% more slowly than they would if they were surrounded by clear, bloomless waters. read more here.

Widespread movement of meltwater onto and across Antarctic ice shelves

DOI: 10.1038/nature22049
Abstract: Surface meltwater drains across ice sheets, forming melt ponds that can trigger ice-shelf collapse, acceleration of grounded ice flow and increased sea-level rise. Numerical models of the Antarctic Ice Sheet that incorporate meltwater’s impact on… read more here.

DOI: 10.1038/s41467-024-45010-x
Abstract: The offshore ocean heat supplied to the Antarctic continental shelves by warm eddies has the potential to greatly impact the melting rates of ice shelves and subsequent global sea level rise. While featured in modeling… read more here.

DOI: 10.1038/s41558-017-0020-x
Abstract: Floating ice shelves, which fringe most of Antarctica’s coastline, regulate ice flow into the Southern Ocean1–3. Their thinning4–7 or disintegration8,9 can cause upstream acceleration of grounded ice and raise global sea levels. So far the… read more here.

DOI: 10.1038/s41598-025-05129-3
Abstract: Antarctic ice shelves play a pivotal role in global sea-level regulation, yet their sensitivity to temperature variations, freeze-thaw cycles, and biotic factors such as snow algae remains under-explored. This study addresses the critical question: how… read more here.
