Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate is critical to better understand the global carbon cycle, support the development of climate policies…
Groundwater response to climate variations is often pivotal to managing groundwater sustainably. However, this relationship is rarely explicitly examined because of the complexity of surface to subsurface processes and the diverse impacts of multiple drivers…
We discuss an upcoming international airborne survey targeting two of the East Antarctica Ice Sheet's (EAIS) enigmatic … subglacial basins. Using a multi-instrumented long range aircraft we will address key issues in the origin and fate of … Earth's largest ice sheet.
Commercial sealers exterminated the original … fur seal population at Macquarie Island in the early 1800s. The Wrst breeding record since the sealing era was not … reported until March 1955. Three species of fur seal now … occur at Macquarie Island, the Antarctic (Arctocephalus … gazella)…
Ice cores provide a suite of proxy variables which respond to potentially complex and non-linear interactions between … many climatic and environmental variables. This complexity can obscure identification of links between ice core … measurements and classical climate variables.
Russian and Australian primary sources were examined in an attempt to reconstruct the voyage of the … first composite Soviet Antarctic expedition to Antarctica and from thence to Leningrad [St Petersburg].
Climate change is predicted to affect high latitudes first and most severely, and major changes in temperature, wind speed and stratospheric ozone have already been observed in Antarctica.
Pressure variations at 11 Antarctic and 7 Arctic sites show significant day-to-day correlations with a proxy for the … meteorological generators (thunderstorms and strongly electrified clouds) of the atmospheric circuit. The proxy is … derived from electric field measurements at Vostok (78.5ºS…
The atmospheric electric field Ez measured at the Antarctic Plateau station of Vostok made it possible to estimate … the role of the main generators in formation the global electric circuit. In the polar region during the periods with good … weather conditions the classical diurnal curve…
The temeperate glaciers of the sub-Antarctic islands are located on a cold, wet, maritime environments making them … valuable climatic indicators for the Southern Ocean. The changes in the glacier fronts on Heard, Kerguelen, Crozet, Marion, Bouvetoya, South Gerogia…
Because of the vast reservoirs of water mass held in the great ice sheets of Antarctica and Greenland, determining the … role that they play in global sea level has long been a major challenge of polar science. But until recent advances in … measurement technology…
The Antarctic Biodiversity Database developed and hosted by the Australian Antarctic Data Centre (AADC), holds data and information on Antarctic and subantarctic flora and fauna in support of the SCAR Life Sciences programme Evolution and Biodiversity in the Antarctic (EBA).
Hundreds of thousands of seabirds are killed each year as a result of interacting with longline … and trawl fishing operations, and the severity of the impact varies regionally. Shy and whitecapped … albatrosses, Thalassarche cauta and Thalassarche steadi respectively…
