1. Marine invasive species can cause irreparable change in new environments, though not all non-native … species inevitably cause negative impacts to recipient … ecosystems.
The globally significant communities of terrestrial Antarctica face an uncertain future amid growing threats in the region. Emerging data-driven approaches must be leveraged to predict and understand patterns of biodiversity across the continent.
There is growing evidence that the Antarctic is increasingly exposed to chemical stressors. Antarctica is impacted by global issues such as climate change and long-range transport of chemicals. Furthermore, expanding tourism and research activities…
Prior to the satellite era, ice core records have been used as a proxy for past sea-ice extent in Antarctica. This information is important for investigating long-term trends in sea-ice coverage.
CryoSat-2 was launched in April 2010, as part of the European Space agency's (ESA) Earth Opportunity Programmes.
The joint TOT-Cal / CryoVExANT2011 project contributes to the validation of the CryoSat-2 altimetry mission through investigations of a key portion of the East Antarctic ice sheet near Australia’s Casey Station. Spanning parts of Law Dome and the Totten Glacier…
The TotCal / CryoVExANT2011 project is an Australian and German collaboration that contributes to the validation of the CryoSat-2 radar altimetry mission through investigations of a key portion of East Antarctica near the Australian Casey Station.
Sea ice plays an important role in ocean–atmosphere heat exchange, global albedo and the marine ecosystem. Knowledge of variation in sea-ice extent is essential in order to understand past climates, and to model possible future climate scenarios.
A compilation of sea salt data from East Antarctic ice cores are used to quantify the contribution of open ocean and sea ice to the sea salt budget. The ice cores used in this study are from Law Dome, Totten Glacier, Wilkes Land and Wilhelm II Land.
Coastal Antarctic sea salt aerosols are partitioned into two main sources, namely ocean sea spray and surface sea ice. The sea spray source is related to windiness over the surface ocean and the action of bubbles bursting.
Oceanographic measurements were conducted in the vicinity of the Mertz Polynya, encompassing 2 consecutive seasonal cycles from 1998 to 2000. In the southern winter of 1999, a total of 92 CTD/LADCP vertical profile stations were taken, most to within 20 m of the bottom…
Oceanographic measurements were conducted in the vicinity of the Amery Ice Shelf on two cruises, during the southern summers of 2000/2001 and 2001/2002. A CTD transect parallel to the front of the Amery Ice Shelf was occupied on both cruises, including repeat occupations on each cruise.
The relationship between Ade´ lie Penguins (Pygoscelis adeliae) and ice is well … established, with sea ice influencing penguin populations through a variety of processes … operating at different spatial and temporal scales.
Six ice cores were collected during the 1997/1998 summer season along the 2000 m contour of Wilhelm II Land (ASAC 2085), followed by fifteen cores the following season from the 1800, 1500 and 1000 m contours in the same area (ASAC 1109)…
Induction magnetometer data recorded at three closely spaced sites (110km) in Antarctica (mlat -75°) have been examined for ionospheric signatures of the outer magnetosphere and cusp/cleft regions. Cross-phase analysis of the 1–10 mHz band…
