The Antarctic vortex of October–December 2020 was the strongest on record in the satellite era for the season in the mid- to lower stratosphere. However, it was poorly predicted by the Australian Bureau of Meteorology's operational seasonal climate forecast system of that time, ACCESS-S1…
Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging…
Executive Summary: This Report summarises the outcomes of a Workshop on the topic of climate tipping points. While it contains a limited number of key references and points from the wider literature…
Antarctic climate warming and atmospheric CO2 rise during the last deglaciation may be attributed in part to sea ice reduction in the Southern Ocean. Yet, glacial–interglacial Antarctic sea ice dynamics and underlying mechanisms are poorly constrained, as robust sea ice proxy evidence is sparse.
Trends in surface atmospheric variables, namely temperature, wind speed and direction, cloud cover, and precipitation, display subtle patterns that are likely linked to climate change and the major modes of climate variability. In particular…
The Kerguelen Plateau, located in the Indian Ocean sector of the Southern Ocean, is the second largest submarine plateau in the world. Despite the remoteness of the islands that emerge from the Plateau…
This review of late-Holocene palaeoclimatology represents the results from a PAGES/CLIVAR … Intersection Panel meeting that took place in June 2006. The review is in three parts: the principal high-resolution … proxy disciplines (trees, corals, ice cores and documentary evidence)…
The Agreement on the Conservation of Albatrosses and Petrels (ACAP) is a newly-constituted international treaty that as yet may be little … known to marine ornithologists around the world. We outline the rationale for the existence of the Agreement, the history of its development…
Sea ice observations are difficult to obtain in sufficient temporal and spatial resolution. Several observational techniques have been used to build a sea ice record of ice … concentration, ice extent, and ice thickness among other things. Satellite measurements are … varied in their capabilities…
The Cryosphere and Climate Project (CliC) c~-ordinates climate activities related to all … parts of the earth's cryosphere. This includes sea ice, snow, ice shelves, ice bergs, lake ice, and permafrost. This talk will give a brief overview of the CliC project…
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.
Once again Antarctica is under threat with the proposal by Senator Barnaby Joyce to have mining sanctioned by the Australian Government. Dr Tracey Rogers, presenter of the 2006 J D Stewart Address at the University of Sydney Faculty of Veterinary Science…
The initial aim of the research, beginning in the 02/03 season, was to undertake some … regional mapping of the ice shelf, and to determine if marine ice could be differentiated from … meteoric ice employing the seismic technique. In 2002/2003…
The diet of grey-headed albatrosses at Diego Ramírez was analysed and compared to that of the … sympatric black-browed albatross. Diet composition was inferred from an analysis of prey hard parts present … in 103 chick regurgitates obtained during breeding seasons 2000, 2001 and 2002.
The thesis contains 13 research papers, of which 10 published and 3 in various stages of submission/acceptance. Papers in chapters 2-7 deal with results from ship-based research on top predator communities or individual bird species in the pelagic environment.
Bryophytes are sensitive indicators of environmental change and with climate change being expected to occur first at high latitudes, Antarctic bryophytes are ideal study systems for the detection of climate change effects.
