Study of the impact of ice formation in leads upon the sea ice pack mass balance using a new frazil and grease ice parameterisation [PDF]
, 2015 Leads are cracks in sea ice that often form due to deformation. During winter months leads expose the ocean to the cold atmosphere resulting in supercooling and the formation of frazil ice crystals within the mixed layer.

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

A Bayesian Model for 20th Century Antarctic Sea Ice Extent Reconstruction
Earth and Space ScienceAntarctic sea ice, a key component in the complex Antarctic climate system, is an important driver and indicator of the global climate. In the relatively short satellite‐observed period from 1979 to 2022 the sea ice extent has continuously increased ...

Change and Variability in East Antarctic Sea Ice, and Its Implications [PDF]
, 2016 Although Antarctic sea ice has undergone a small increase in overall extent over the past 30 years, major regional changes have occurred in sea ice coverage in response to changing patterns of large-scale atmospheric circulation.

A high-resolution bedrock map for the Antarctic Peninsula [PDF]
, 2014 Assessing and projecting the dynamic response of glaciers on the Antarctic Peninsula to changed atmospheric and oceanic forcing requires high-resolution ice thickness data as an essential geometric constraint for ice flow models.

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins
Remote Sensing in Ecology and Conservation, EarlyView.Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Aspects of resilience of polar sea ice algae to changes in their environment [PDF]
, 2015 Sea ice algae are primary producers of the ice-covered oceans in both polar regions. Changes in sea ice distribution are potentially altering exposure to photosynthetically active radiation (PAR) and ultraviolet-B (UV-B) wavelengths of light. Incubations

Record phenological responses to climate change in three sympatric penguin species
Journal of Animal Ecology, EarlyView.This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

The association of Antarctic krill Euphausia superba with the under-ice habitat.
PLoS ONE, 2012 The association of Antarctic krill Euphausia superba with the under-ice habitat was investigated in the Lazarev Sea (Southern Ocean) during austral summer, autumn and winter.
