[1] In September–October 2005, the juxtaposition of low- and high-pressure anomalies at … 130W and 60W, respectively, created strong and persistent northerly airflow across the … West Antarctic Peninsula (WAP). This had a major impact on regional sea ice conditions…
For wildlife managers, determining inter-species differences in the behavioral responses of seabirds to visitation can allow … greater efficacy of visitor guidelines. Two key management outcomes for such information include 1)…
Reports of a variety of short-term meteorological responses to changes in the global electric circuit associated with a set of disparate … inputs are analyzed. The meteorological responses consist of changes in cloud cover, atmospheric temperature, pressure, or dynamics.
Understanding and characterising the variability of ozone in the lower atmosphere is a key aspect of … regional and global climate assessment. Tropospheric ozone influences climate by absorbing outgoing … longwave terrestrial radiation, thereby acting as a greenhouse gas…
Antarctic fast ice is of key climatic and ecological importance, yet its distribution and variability are poorly understood (compared to pack ice). In this joint Australian-French study…
Quantifying the contribution of solar variability to past and present climate change has been an important and controversial aspect of climate research. 10Be records from polar ice have played a key role in extending solar activity reconstructions beyond the period of direct observations of the sun.
The Super Dual Auroral Radar Network (SuperDARN) is an international network of oblique HF over-the-horizon … radars dedicated to the study of high latitude magnetosphere-ionosphere convection. In scientific terms, they have been … an outstanding success…
Reports of a variety of meteorological responses to short-term changes in the global electric circuit … associated with a number of disparate inputs are analyzed. The meteorological responses consist of changes in cloud … cover, atmospheric temperature, pressure, or dynamics.
Bacteria play a key role in the world's oceans, supporting nutrient remineratlisation and mediating … carbon transfer. Most studies of marine bacteria in the … Southern Ocean are restricted to the summer months. Thus…
Populations of Southern Rockhopper ( Euduptes chrysocome chrysocome … ) and Macaroni ( E. chrysolophus … ) Penguins at key breeding sites in the Southern Hemisphere have declined substantially in the past 50 years, but … their statuses at important breeding sites in southern Chile are poorly known.
Although satellite passive-microwave remote sensing is the main source of global sea-ice … information, the data products have never been adequately validated for East Antarctic … conditions.
Thicknesses of sea ice and snow are key variables in ice-ocean-atmosphere interactions. Sea ice insulates the warm ocean from polar air and controls the heat exchange, which is … determined by its thickness. Also, sea ice thicknesses, together with sea ice extent…
Krill are thought to be predominantly herbivorous, but a heterotrophic diet might be crucial for … their growth and survival. To compare the influence of herbivory and carnivory on krill we conducted a nine … month feeding trial. We examined lipid composition of the hepatopancreas…
Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.
Climate change is expected to affect the high latitudes first and most severely, rendering … Antarctica one of the most significant baseline environments for the study of global … climate change. The indirect effects of climate warming…
The Australian Antarctic Data Centre (AADC) plays a key role in managing and providing … access to scientific data collected under the auspices of the Australian Antarctic program. Through its membership of the Joint Committee of Antarctic Data Management (JCADM)…
This study examines the molecular-genetic divergence and evolution of Australian aquatic micro-Crustacea Daphnia … and Daphniopsis. The results indicate that species of Daphniopsis are accommodated within the genus Daphnia. Although their phyletic integrity is no longer supported…
The degree to which Southern Hemisphere climatic changes during the end of the last … glacial period and early Holocene (30-8 ka) were influenced or initiated by events occurring in the high … latitudes of the Northern Hemisphere is a complex issue.
The CLIVAR (Climate Variability and Predictability)/CliC (Climate and Cryosphere)/ SCAR … (Scientific Committee on Antarctic Research) Southern Ocean region panel is charged with … refining and implementing the science plans of CLIVAR, CliC and SCAR in the Southern … Ocean Sector.
Marine conservation on the high seas has emerged on the international agenda as a critical … issue requiring the application of novel approaches, international cooperation and political will. In the Southern Ocean…
Southern elephant seals (Mirounga leonina) are a major consumer of biomass in the … Southern Ocean with a global distribution.
