ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Returning Climate to Present Day May not Reduce Antarctic Mass Loss
Abstract Using the BISICLES ice sheet model, we explore the Antarctic Ice Sheet's response over the 22nd century under two climate scenarios. In the return scenario, climate forcing is returned to present‐day levels (2015) in either 2050 or 2100 and then held constant until 2200.

Abstract Dense water formation in the Southern Ocean plays a key role in the global ocean overturning circulation, affecting the distribution of heat, carbon, oxygen, and nutrients. Fast ice stays immobile while blocking sea ice flow, favoring the opening of coastal polynyas, where intense air‐sea exchanges drive sea ice production and ocean ...

Baffin Bay Freshwater Content Seasonal Variability and Budget: A Modeling Approach
Abstract Baffin Bay plays a significant role as an exporter of freshwater from the Arctic to the North Atlantic. However, we still do not completely understand how this freshwater is stored and transformed within the bay before it exits. Here, we use a six‐member ensemble built using the Nucleus for European Modelling of the Ocean (NEMO)—at 1/4 ...

Abstract Iceberg calving driven by crevasse propagation is an important source of ice loss from the Greenland and Antarctic ice sheets. However, simulating crevasse growth and interaction in 3D, spanning meters to kilometers length scales, remains computationally challenging for high‐fidelity models based on nonlocal continuum damage mechanics and ...

Thermal flexure and glacier calving
Glaciers and ice sheets that terminate in bodies of water are expected to undergo thermal expansion as ice comes into contact with much warmer liquid water. Here, I investigate the roll that this thermal expansion plays in the fracturing processes that give rise to glacier calving.

Calving front positions for 42 key glaciers of the Antarctic Peninsula Ice Sheet: a sub-seasonal record from 2013 to 2023 based on deep-learning application to Landsat multi-spectral imagery [PDF]
Calving front positions of marine-terminating glaciers are an essential parameter for understanding dynamic glacier changes and constraining ice modelling.
