A fast and efficient solver for viscous-plastic sea ice dynamics
Sea ice plays a key role in the global climate system. Indeed, through the albedo effect it reflects significant solar radiation away from the oceans, while it also plays a key role in the momentum and heat transfer between the atmosphere and ocean by acting as an insulating layer between the two. …

A Small-Scale Model of Sea Ice Dynamics in the Antarctic Marginal Ice Zone Using Fluid-Structure Interaction and the Reference Map Technique
Sea ice covers approximately 10% of the Earth's surface and modulates the sea-air heat and momentum exchange, therefore playing a major role in the global climate. The Antarctic marginal ice zone (MIZ) is the seasonally varying region between the open Southern Ocean and the Antarctic pack ice. It …

SHARC Buoy: Robust firmware design for a novel, low-cost autonomous platform for the Antarctic Marginal Ice Zone in the Southern Ocean
Sea ice in the Antarctic Marginal Ice Zone (MIZ) plays a pivotal role in regulating heat and energy exchange between oceanic and atmospheric systems, which drive global climate. Current understanding of Southern Ocean sea ice dynamics is poor with temporal and spatial gaps in critical seasonal …

Computational modelling of ice floe dynamics in the Antarctic marginal ice zone.
The contribution of Antarctic sea ice in global climate models requires a more accurately estimation, as a relatively large part, approximately 4% of the Earth's surface in the winter season, is covered by sea ice. Understanding the dynamic and thermodynamic processes of sea ice, results in a …

Mesoscale Wind and Temperature Changes over Peatlands of the Hudson Bay Lowlands: impacts on the Surface Energy Balance and Net CO2 Exchange
… warming has caused observed changes in the sea ice dynamics and energy budget of the Hudson Bay, yet it is presently unknown how these climatic changes in the Bay will impact the surface energy and carbon balance of the adjacent HBL. As a globally significant peatland carbon pool, the HBL …

Phase field modeling of dynamic brittle fracture at finite strains
… in tension, shear and compression. This research is part of a larger project aimed at the modeling of Antarctic sea ice dynamics. One aspect of this project is the modeling of the gradual break-up of the consolidated ice during spring. As a first step, this study reviews a phase field model …

Assessment of early 20th Century climate model simulations of Antarctic Sea ice using historical commercial humpback whale catch data
… try understand its oceanographic features. The seasonal sea ice cover represents one major feature of this system. This study proposes to use other sources of data for the early 20th century that will help closing the gap prior to satellite observations. Humpback whales migrate poleward during …

An investigation of wind- and wave-driven dynamics in Antarctic sea ice from multiple types of buoy arrays
The advance and retreat of Antarctic sea ice is the largest annually recurring event on Earth, and a significant portion of its natural variability appears to be associated with synoptic variability. Therefore, attaining a comprehensive understanding of both the dynamic and thermodynamic processes …
