The Mount Brown South ice core (MBS 69.111S 86.312E) is a new, high resolution ice core drilled in coastal East Antarctica. With mean annual accumulation estimated to be ~30 cm ice equivalent throughout the length of the core (~290 m)…
Peter I Island is situated in the Bellingshausen Sea, a region that has experienced considerable climate change in recent decades. Warming sea surface temperatures and reduced sea ice cover have been accompanied by warming surface air temperature, increased snowfall…
As whales recover from commercial exploitation, they are increasing in abundance in habitats that they have been absent from for decades. However, studying the recovery and habitat use patterns of whales, particularly in remote and inaccessible regions…
Among large cetaceans in the Southern Hemisphere, fin whales were the most heavily exploited in terms of numbers taken during the period of intense industrial whaling. Recent studies suggest that…
Blue whales Balaenoptera musculus at South Georgia were heavily exploited during 20th century industrial whaling, to the point of local near-extirpation. Although legal whaling for blue whales ceased in the 1960s…
Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, whales have once again become summer visitors, with the southern right whale (SRW) the most commonly reported species until 2011. Here…
Baleen whales are predominately summer visitors to Antarctic waters, where they feed on large swarms of zooplankton, primarily Antarctic Krill (Euphausia superba). Over 2 million whales were killed in Southern Hemisphere whaling operations in the 20th Century 1.
We report high resolution measurements of the stable water isotope ratios (?18O, ?D) from the Mount Brown South ice core (MBS, 69.11° S 86.31° E). The record covers the period 873 - 2009 CE with sub-annual temporal resolution.
Water stable isotope records from ice cores (?18O and ?D) are a critical tool for constraining long-term temperature variability at high latitudes. However, precipitation in Antarctica consists of semi-continuous small events and intermittent extreme events. In regions of high accumulation…
Sub-Antarctic islands and Antarctic coastal regions provide valuable sites for investigating environmental processes in the Southern Ocean.
Among large cetaceans in the Southern Hemisphere, fin whales were the most heavily exploited in terms of numbers taken during the period of intense industrial whaling. Recent studies suggest that…
As we learn more about the importance of cetaceans in the Antarctic, including their populations' recovery and needs as krill and fish predators, it is increasingly clear that cetacean science is vital for informing ecosystem-based management.
The success of IPY and the advent of Operation Ice Bridge, coupled with new developments in … technology are significantly contributing to our understanding of the Earth ice sheets. Here we … review radar sounding results from the recent campaigns in West and East Antarctica…
This paper places the sub-Antarctic region in its international context by contrasting the sub-Antarctic’s geographical qualities with the region’s international legal and political characteristics.
The policy arm of the Australian Antarctic program is developing strong links with research and tertiary teaching programs in the Australian academinc community.
