As a result of selective pressures faced during lactation, vocal recognition may … play a crucial role in maintaining the phocid mother–pup bond during the period … of dependence. To investigate this possibility, we examined whether Weddell seal … (Leptonychotes weddellii)…
Models of variability in Adélie penguin foraging trip durations were constructed and fitted … to data collected at Béchervaise Island over a 12-year period when only natural variation … was known to occur. Variability among trips and penguins was greater in the crèche … stage…
Micro-organisms are an important part of the Antarctic ecosystem contributing to the biogeochemical cycling of nutrients.
Abstract A microbial enrichment culture tolerant of … petroleum hydrocarbons was developed from sediment … collected near Casey Station, Antarctica. To select coldadapted … microbes that would degrade diesel, enrichments … were cultured at 0°C during six successive … transfers to fresh medium…
The effects of diesel fuel and three lubricating oils on microbial communities in marine sediment were investigated in a field experiment at Casey Station, Antarctica. Sediment from a pristine site in Antarctica was treated with either Special Antarctic Blend (SAB) diesel, a synthetic lubricant…
A field experiment investigating the effect of oil contamination on benthic microbial communities was conducted near Casey Station, East Antarctica.
This study addresses the consequences of repeated … human handling on the survival of an endangered phocid, the southern elephant seal and the implications for wildlife … research. Southern elephant seal pups were repeatedly … handled during the first six weeks of their lives.
We present water column profiles of excess particulate Ba (Baxs, an estimate of biogenic Ba from total particulate Ba … after small corrections for lithogenic Ba) along a transect in the Australian sector of the Southern Ocean from the … Subantarctic Zone (SAZ) to the Sea Ice Zone during spring…
This paper describes the diet and foraging behaviour of Adélie penguins (Pygoscelis adeliae) at Béchervaise Island during 1998-99, a season of low breeding success. Fifty six percent of nests with eggs failed during the three weeks following first hatch. A breeding success of 0.
High-resolution Fabry-Perot spectrometer observations of the OH(62) Q1(1) line, l834.46 nm, were made at Mawson, 67.6ºS 62.9ºE, and Davis, 68.6ºS 78.0ºE, Antarctica, in 1997. The observing program resulted in three sets of continuous OH observations suitable for tidal analysis: July 25…
Eight years ofaltimetry and hydrographic data are used to examine the formation, propagation and vertical … characteristics ofcold-core rings formed north ofthe Subantarctic Front, SAF, in the region south ofTasmania. Altimetry allows us to follow the spatial–temporal evolution of these cold…
South Georgia (540S; 380W) lies 350 km south of the Polar Front in the south-west Atlantic Ocean. It is a key global location for albatrosses: at the last all-island census in 1986, it was estimated that approximately 92,500 pairs of grey-headed albatrosses (most important global site), 101…
