Antarctica is currently losing net mass to the ocean primarily from West Antarctica and the Antarctic Peninsula, which together hold ~5.5?m of sea level rise potential. Yet, the East Antarctic Ice Sheet stores almost ten times more ice…
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of -9.
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. In Part I, we assessed the meteorological drivers that generated an intense atmospheric river (AR)…
Agenda Item(s): WG-IMAF-2022 - 4.2.1 - Review of whale entanglement information … WG-IMAF-2022 - 4.1 - Population status of marine mammals in the CAMLR Convention Area … WG-IMAF-2022 - 4.3 - Mitigation methods for marine mammals
Report submitted to CCAMLR: Leaper, R., Biuw, M., Favero, M, Forster, I., Johnson, C., Kelly, N., Heinemann, D., Hines, E., Landry, S., Mattila, D., Meyer, M., Parker, S., Passadore, C., Reeves, S., Soffker, M., Stimmelmayr, R., Walker, N., 2022.
Evaluating the effects of climate change on Southern Ocean marine living resources is a priority topic for CCAMLR and was identified by the 2022 Scientific Committee Symposium as a key area of research. Acknowledging the need to better coordinate…
The response of the global water cycle to changes in global surface temperature remains an outstanding question in future climate projections and in past climate reconstructions. The stable hydrogen and oxygen isotope compositions of precipitation (?precip), meteoric water (?MW) and seawater (?SW)…
The gammarid Paramoera walkeri is one of the most abundant amphipods in near-shore Antarctic waters. There has been increasing interest in P. walkeri as a test species for ecotoxicology studies and bio-monitoring for contaminants in Antarctica…
One of the serious threats to the Antarctic marine ecosystem is the release of large volumes of petroleum fuel. Numerous fuel spill incidents have occurred and risks of a major spill are increasing due to continued expansion of human activity in the Antarctic region.
Fuel spills in Antarctic waters are increasingly likely with the rise in shipping in the region related to tourism and research activities, both of which require and transport large quantities of fuel. While fuel dispersants are not currently used in the management of fuel spills in Antarctica…
This paper presents extensive {bias determination} analyses of ozone observations from the Atmospheric Chemistry Experiment (ACE) satellite instruments: the ACE Fourier Transform Spectrometer (ACE-FTS)…
The basis of using isotopic measurements to study trophic structure lies in documenting a regular and consistent pattern of isotopic enrichment with increasing trophic level. Nitrogen isotope ratios (δ 15N) in consumers become enriched in 15N by 3-4 % relative to their food…
In January 2005, members of a Chinese expedition team … were the first humans to visit Dome A on the Antarctic plateau, a site … predicted to be one of the very best astronomical sites on earth. In 2006, the Chinese Center for Antarctic Astronomy (CCAA)…
PLATO is a fully-robotic observatory designed for operation … in Antarctica. It generates its own electricity (about 1kW), heat … (sufficient to keep two 10-foot shipping containers comfortably above … 0◦C when the outside temperature is at −70◦C)…
The THz spectral region includes a number of important … transitions which allow us to trace the evolution of the interstellar … medium. Because of the opacity of the atmosphere in this spectral … range, the best sites for ground-based THz observations are on the … Antarctic Plateau; of these sites…
Pre-HEAT is a 20 cm aperture submillimeter-wave telescope with a 660 GHz (450 micron) Schottky diode heterodyne … receiver and digital FFT spectrometer for the Plateau Observatory (PLATO) developed by the University of New South … Wales. In January 2008 it was deployed to Dome A…
