We report on long-term surface elevation changes of the central Amery Ice Shelf … (AIS) by comparing elevation records spanning 4 decades (1968–2007). We use elevation … records acquired with the following methods: optical leveling (1968–1969); ERS … radar altimetry (1992–2003); GPS (1995–2006)…
The stability of Antarctic Bottom Water (AABW) to freshwater (FW) perturbations is investigated in a … coupled climate model of intermediate complexity. It is found that AABW is stable to surface freshwater … fluxes greater in volume and rate to those that permanently “shut down”…
In January 2004 the microplankton community … from the coastal waters of Terre Ade´lie and Georges V Land … (139!E–145!E) was studied. Results showed a diatomdominated … bloom with chlorophyll a levels averaging … 0.64 lg l-1 at 5 m depth (range 0.21–1.57 lg l-1).
We present a computational model of the largescale … cumulative light exposure of sea ice in the Southern … Ocean off East Antarctica (30E–150E). The model uses … remotely sensed or modelled sea ice concentration, snow … depth over sea ice, and solar irradiance data…
Alien microbes, fungi, plants and animals occur on most of the sub-Antarctic islands and some parts of the … Antarctic continent. These have arrived over approximately the last two centuries, coincident with human … activity in the region. Introduction routes have varied…
