Health challenges on research and cruise ship expeditions to Antarctica

Health Promotion & Physical Activity, 2022
Antarctica is one of the last great wilderness areas on Earth. Early Antarctic expeditions during the Heroic Age of Antarctic discovery (1895–1922) returned reports of frostbite, scurvy, snow blindness, and death.

The variability of climate in Indian Ocean sector of East Antarctica over the past 350 years

Лëд и снег, 2015
The temperature and snow accumulation rate anomaly over the past 350 years have been reconstructed based on isotopic composition of shallow ice cores and snow pits samples as well as glaciological observations in pits and at stake farms located in Indian

Snow-driven uncertainty in CryoSat-2-derived Antarctic sea ice thickness – insights from McMurdo Sound [PDF]

The Cryosphere, 2019
Knowledge of the snow depth distribution on Antarctic sea ice is poor but is critical to obtaining sea ice thickness from satellite altimetry measurements of the freeboard.

On the interpretation of ice-shelf flexure measurements

Journal of Glaciology, 2017
Tidal flexure in ice shelf grounding zones has been used extensively in the past to determine grounding line position and ice properties. Although the rheology of ice is viscoelastic at tidal loading frequencies, most modelling studies have assumed some ...

Effects of hydrocarbon spills on the temperature and moisture regimes of Cryosols in the Ross Sea region [PDF]

, 2002
Hydrocarbon spills have occurred on Antarctic soils where fuel oils are utilized, moved or stored. We investigated the effects of hydrocarbon spills on soil temperature and moisture regimes by comparing the properties of existing oil contaminated sites ...

Climate Change and invasibility of the Antarctic benthos [PDF]

, 2007
Benthic communities living in shallow-shelf habitats in Antarctica (<100-m depth) are archaic in their structure and function. Modern predators, including fast-moving, durophagous (skeleton-crushing) bony fish, sharks, and crabs, are rare or absent ...

Influence of Sea-Ice Anomalies on Antarctic Precipitation Using Source Attribution in the Community Earth System Model [PDF]

, 2020
We conduct sensitivity experiments using a general circulation model that has an explicit water source tagging capability forced by prescribed composites of pre-industrial sea-ice concentrations (SICs) and corresponding sea surface temperatures (SSTs) to

Viscosity and elasticity: a model intercomparison of ice-shelf bending in an Antarctic grounding zone

Journal of Glaciology, 2017
Grounding zones are vital to ice-sheet mass balance and its coupling to the global ocean circulation. Processes here determine the mass discharge from the grounded ice sheet, to the floating ice shelves.

Impacts of local human activities on the Antarctic environment [PDF]

, 2008
We review the scientific literature, especially from the past decade, on the impacts of human activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and temporal scales.
