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…
The Antarctic Ice Sheet is integral to Earth's climate system, influencing global energy and water cycles, and ecosystems. Enough ice is stored in regions most vulnerable to rapid retreat to cause sea levels to rise by ?15?m if they completely melted, making their stability a key concern.
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)…
Evaluating the effects of climate change on Antarctic 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, target and integrate scientific advice on climate change…
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.
Antarctica is often considered a pristine wilderness, however, as human occupation and activities in the region increase, it is becoming increasingly apparent that this is not the case.
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…
