Dynamics and influence of environmental processes on the coastal marine system of the Vestfold Hills, East Antarctica Open
Antarctic ice-free coastal environments, like the Vestfold Hills (East Antarctica), are shaped by a complex interplay of physical processes. This study synthesizes new data and existing research from the Vestfold Hills across marine, terre…

The influence of ocean waves on Antarctic sea-ice albedo and seasonal melting, and physical-biological feedbacks Open
Identifying the processes that drive the rapid climatological retreat phase of Antarctica’s annual sea-ice cycle is crucial to understanding, modelling and attributing observed trends and recent high variability in sea-ice extent, and to p…

Impacts of Antarctic summer sea-ice extremes Open
Antarctic sea ice plays many crucial roles in the physical environments and ecosystems of Antarctica and the Southern Ocean. In this study, we synthesize the physical, biogeochemical, ecosystem, and societal impacts of summers with extreme…

Large-scale ice shelf calving events follow prolonged amplifications in flexure Open
The retreat of Antarctic ice shelves due to calving and the subsequent reduction in buttressing of the Antarctic Ice Sheet are of major concern for future sea-level rise. Sudden, widespread calving of weakened ice shelves has been linked t…

Impacts of Atmospheric Dynamics on Sea-Ice and Snow Thickness at a Coastal Site in East Antarctica Open
Antarctic sea ice and its snow cover play a pivotal role in regulating the global climate system. Understanding the intricate interplay between atmospheric dynamics, ocean circulation and mixed-layer properties, and sea ice is essential fo…

Antarctic Landfast Sea Ice: A Review of Its Physics, Biogeochemistry and Ecology Open
Antarctic landfast sea ice (fast ice) is stationary sea ice that is attached to the coast, grounded icebergs, ice shelves, or other protrusions on the continental shelf. Fast ice forms in narrow (generally up to 200 km wide) bands, and ran…

Biological responses to change in Antarctic sea ice habitats Open
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean–atmosphere exchanges and provides an impo…

Model Predictions of Wave Overwash Extent Into the Marginal Ice Zone Open
In the marginal ice zone (MIZ), where ocean waves and sea ice interact, waves can produce flows of water across ice floe surfaces in a process known as wave overwash. Overwash potentially influences wave propagation characteristics, floe t…

Altimetric observation of wave attenuation through the Antarctic marginal ice zone using ICESat-2 Open
The Antarctic marginal ice zone (MIZ) is a highly dynamic region where sea ice interacts with ocean surface waves generated in ice-free areas of the Southern Ocean. Improved large-scale (satellite-based) estimates of MIZ extent and variabi…

Model predictions of wave overwash extent into the marginal ice zone Open
A model of the extent of wave driven overwash into fields of sea ice floes is proposed. The extent model builds on previous work modelling wave overwash of a single floe by regular waves by including irregular incoming waves and random flo…
View article: Sea ice-free corridors for large swell to reach Antarctic ice shelves
Sea ice-free corridors for large swell to reach Antarctic ice shelves Open
Sea ice can attenuate Southern Ocean swell before it reaches Antarctic ice shelves and imposes flexural stresses, which promote calving of outer ice-shelf margins and influence ice shelf stability. An algorithm is developed to identify sea…
