Since 2001, hundreds of thousands of hours of underwater acoustic recordings have been made throughout the Southern Ocean south of 60° S. Detailed analysis of the occurrence of marine mammal sounds in these circumpolar recordings could provide novel insights into their ecology…
Understanding how sea ice serves zooplankton species during the food-limited season is crucial information to evaluate the potential responses of pelagic food webs to changes in sea-ice conditions in the Southern Ocean. Stable isotope analyses (13C/12C and 15N/14N)…
Lead (Pb) isotopic compositions and concentrations, and barium (Ba) and indium (In) concentrations have been determined at monthly resolution in five Law Dome (coastal Eastern Antarctica) ice core sections dated from ~1757 AD to ~1898 AD. [`]…
Bacterial community structures in soils collected … from eight sites around Casey Station, Antarctica, were … investigated using denaturing gradient gel electrophoresis … (DGGE) of ampliWed 16S rRNA gene fragments.
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
ABSTRACT: Collisions with vessels are a well-documented conservation problem for some populations of large whales (LW) in the Northern Hemisphere. Less attention has been given to incidents in the Southern Hemisphere or to small cetaceans … (SC) worldwide…
Antarctic ice is an archive of evidence of climatic conditions and natural phenomena in the … Southern Hemisphere that extends approximately one million years into the past. We can … sense changes through the concentration of atmospheric gases, stable isotope ratios, terrestrial dust levels…
Dome A is the highest point on the surface of the East Antarctic ice sheet and the highest … ice feature in Antarctica. In January 2005 a team from the Chinese National Antarctic … Research Expeditions (CHINARE)…
Ice shelves play a major role in the discharge of ice from Antarctica both from iceberg calving and basal melt, and processes of ocean-ice interaction beneath the shelf are of increasing scientific interest.
