The CHinense Exoplanet Searching Program from Antarctica is a ground-based wide-field photometric survey using the AST3 and CSTAR telescopes located at Dome A, Antarctica. Blessed with the unparalleled observing conditions on the highest point of the Antarctic plateau, three remotely controlled…
The SCAR Krill Expert Group (SKEG) aims to improve the understanding of krill biology and ecology and serve as a link between the scientific krill community and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which manages the Antarctic krill fishery.
The response of oceanic phytoplankton to … climate forcing in the Arctic Ocean has attracted … increasing attention due to its special geographical … position and potential susceptibility to global warming. Here, we examine the relationship between satellitederived …
Polar Mesospheric Clouds (PMC) are a ubiquitous wide-spread optical … phenomena of the polar summer mesopause region, and comprise icy … aerosols that form under the influence of large-scale atmospheric ascent … and adiabatic cooling. PMC aerosols are controlled by the thermal…
The dual HF radars comprising the Tasman International … Geophysical Environment Radar (TIGER) system … often observe localized high-velocity F-region plasma flows … (1500 m/s) in the midnight sector (20:00–02:00 MLT) at … magnetic latitudes as low as 3=60 S.
Exceptional sea ice conditions occurred in the West Antarctic Peninsula (WAP) region from September … 2001 to February 2002, resulting from a strongly positive atmospheric pressure anomaly in the South … Atlantic coupled with strong negative anomalies in the Bellingshausen…
There is much speculation over the role of frazil ice in both ocean cavities under ice shelves and in the adjacent ocean where Ice Shelf Water (ISW) plumes are found. Traditionally three-dimensional ocean circulation models have ignored this slurry of small, thin…

In recent years there has been increasing interest in the role of frazil ice in ocean cavities … under ice shelves and in the adjacent ocean, where plumes of Ice Shelf Water (ISW), colder … than the sea-water surface freezing point, are observed. The development of frazil ice - suspensions of small…
Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon … export from the surface ocean. This requires determination of both the 234Th activity distribution (in order to calculate 234Th fluxes)…
During Match 1998 we studied in situ bio-optical parameters along a north-south transect (142?¡E) between 42¡ and 55?¡S. Surface chlorophyll a (chl a) reflected mixed layer chl a concentrations and showed a general decrease with increasing latitude.
A Lowell Digital Ionosonde (DPS-4) has operated at the Australian Antarctic polar cap station Casey (-80.6o CGM latitude), since early 1993, primarily to study the dynamics of the southern polar cap ionosphere. To gain a better understanding of the ionospheric motions involved…
