Antarctic Bottom Water (AABW) is the densest water mass in the world and drives the lower limb of the global thermohaline circulation. AABW is formed in only four regions around Antarctica and Cape Darnley, East Antarctica, is the most recently discovered formation region. Here…
When seawater freezes, sea ice forms. Though seemingly straightforward, the formation, growth, and decay of sea ice involve complexities. Sea ice, its extent, and its physical properties are of paramount importance to the climate system. This is in large part due to its vast coverage at the poles.
Detailed knowledge of the sub-glacial morphology of large ice sheets is essential for … refining ice sheet models and the associated sea-level rise predictions under a warming … environment.
The distribution of euphausiid larvae along the coast of Terre Ade´lie, Antarctica, was assessed using … oblique tows of a double-framed bongo net at 38 stations during summer 2004. Larvae of Euphausia … crystallorophias and Thysanoessa macrura were observed. For E. crystallorophias larvae…
Knowledge of penguin abundance at regional and circumpolar scales across the Southern Ocean is important … for the development of ecosystem models and to estimate prey consumption by penguins to assess potential competition … with fisheries’ operations.
The influence of biotic and environmental variables on the abundance of virus-like … particles (VLP) and lysogeny was investigated by examining 10 Antarctic lakes in … the Vestfold Hills, Antarctica, in the Austral Spring.
The dynamics of animal populations are determined by several key demographic parameters, which vary over time with resultant changes in the status of the population. When managing … declining populations, the identification of the parameters that drive such change are a high priority…
Graphical methods for the exploration of ecological databases … Ben Raymond, Lee Belbin, Jonathan Stark … Scientific data repositories are becoming increasingly characterised by large data sets stored in web-accessible, structured databases.
The distribution of mean net accumulation rate over a large sector (90°E to 150°E) of the IAGP (International Glaciological Project) area is presented in map form. The basic data have been compiled from direct measurements of accumulation at stake networks…
