The effect of ice shelf rheology on shelf edge bending
The CryosphereAbstract. The distribution of pressure on the vertical seaward front of an ice shelf has been shown to cause downward bending of the shelf if the ice is assumed to have vertically uniform viscosity. Satellite lidar observations show that many shelf edges bend upward and that the amplitude of upward deflections depends systematically on ice shelf ...

Thermokarst Lagoons: Distribution, Classification and Dynamics in Permafrost‐to‐Marine Transitions
Permafrost and Periglacial Processes, EarlyView.ABSTRACT The transition of permafrost landscapes to marine environments, driven by climate change, plays a crucial role in the global carbon cycle. Thermokarst lagoons, formed along permafrost coasts when thermokarst lakes get connected to the sea, are key features in this transition.

Ross Ice Shelf Displacement and Elastic Plate Waves Induced by Whillans Ice Stream Slip Events
Geophysical Research LettersIce shelves are assumed to flow steadily from their grounding lines to the ice front. We report the detection of ice‐propagating extensional Lamb (plate) waves accompanied by pulses of permanent ice shelf displacement observed by co‐located Global ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Marine winds near coastal Antarctica are important for sea‐ice variability and ocean circulation. We test the sensitivity of simulated winds to varying uncertain aspects of the atmospheric model configuration. Winds (each configuration a coloured solid line in the figure) are sensitive to model physics, and notably we find that wind stress over a ...

A Predictive Theory for Heat Transport Into Ice Shelf Cavities
Geophysical Research LettersAntarctic ice shelves are losing mass at drastically different rates, primarily due to differing rates of oceanic heat supply to their bases. However, a generalized theory for the inflow of relatively warm water into ice shelf cavities is lacking.
