Vincennes Bay is a region of East Antarctica vulnerable to sub-ice shelf basal melting from warm ocean water intrusions. The sub-ice shelf bathymetry in this region is largely unknown, despite its importance for ocean dynamics within ice shelf cavities and associated sub-ice shelf basal melting.
Much of the Antarctic coast is covered by seasonal landfast sea ice (fast ice), which serves as an … important habitat for ice algae. Fast?ice algae provide a key early season food source for pelagic and benthic … food webs, and contribute to biogeochemical cycling in Antarctic coastal ecosystems.
A southern right whale (Eubalaena australis) was found dead, stranded on a remote rock platform at Torndirrup, Western Australia, on 20 September 2022.
Catch per unit effort (CPUE) is often the only data available from historical fisheries for inferring distribution and abundance of exploited populations. CPUE underestimates variations in relative abundance when gross effort data are only measured in total operating days.
The mid- to high-latitudes of the Southern Hemisphere are dominated by the westerly winds. These are important because changes in their strength determine precipitation and temperature regimes. However, little is known about their past strength, or spatial and temporal variability.
The sub-Antarctic region between 45-60°S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.
The sub-Antarctic region between 45-60 °S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.
Sub-Antarctic islands are the only landmasses between Antarctica and South America, Africa and Australia where terrestrial climate and ecosystem records are available, making them crucial locations for linking southern mid and high latitude regions. However…
Simulations of the ocean dynamics in the cavity under the Amery Ice Shelf, Antarctica, were carried out using a three-dimensional numerical ocean model. Two different boundary conditions were used to describe the open ocean barotropic exchange at the ice front.
Aims: This study was undertaken to examine and characterize Antarctic marine bacterial isolates and the … exopolysaccharides (EPS) they produce in laboratory culture. Methods and Results:
The diet composition of King penguins Aptenodytes patagonicus at Heard Island (53°05S; 73°30E) was determined from stomach contents of 98 adults captured as they returned to the island throughout 1992. During the two growth seasons…
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…
