Fuel spills have occurred in Antarctic and sub-Antarctic regions, and comprehensive remediation strategies have recently been established to clean-up fuel spills at Australia’s Casey Station and Macquarie Island. However…
Chemical contamination resulting from human activities has been identified in … nearshore marine environments in the vicinity of Antarctic Research Stations. To better … manage and remediate contaminated sites, and to assess the risks of ongoing activities…
Developing water quality guidelines for Antarctic marine environments requires understanding sensitivity of biota to contaminant exposure. Toxicity tests with Antarctic … invertebrates have shown response times to metal exposure takes far longer than the durations of standard bioassay methods.
While definitive winter measurements for Dome C must await until 2004, on the basis of existing data the Antarctic … Dome sites promise the best conditions on the Earth for many astronomical observations. Because atmospheric … turbulence is largely confined to a ~ 100 m ground layer…
Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.
A new Scanning Doppler Imager (SDI) has been constructed and recently located to Mawson, Antarctica. The SDI is a separation scanning Fabry-Perot Interferometer (FPI) coupled to an all-sky lens and imaging detector. This permits rapid scanning of the interference fringes over most of the sky.
The Marine Science Voyage (2010/11 VMS) to the Mertz Glacier region was a collaborative survey involving scientists from a number of research institutions, working across a number of different projects…
A baseline for persistent organohalogen compound (POC) accumulation in the Antarctic … keystone species, Antarctic krill (Euphausia superba) has been established for a 50¡ã longitudinal … range of the eastern Antarctic sector. Samples of adult krill…
Abstract Samples of marine ice were collected from … the Amery Ice Shelf, a large embayed ice shelf in East … Antarctica, during the Austral summer of 2001–2002. The samples came from a site ~90 km from the iceberg … calving front of the shelf…
In 2001 and 2003 small-scale acoustic surveys of Antarctic krill (Euphausia superba) distribution and abundance were conducted … offshore from an East Antarctic colony of Adelie penguins on Bechervaise Island (671350S, 621490E) that has been monitored for … 15 years.
After an unusually (for recent solar cycles) long absence, sunspots of solar cycle 24 started to appear late in 2009. Cosmic ray activity monitored at Earth has an inverse … relationship with the sunspot cycle, being maximum at solar … minimum.
Ice core records from Antarctic and Greenland have revealed that the last deglaciation (ca. 19,000 to 11,000 years before present) was accompanied by a ca. 80 ppmv increase in atmospheric CO2 and a sequence of large, hemispheric climate variations.

1. The likelihood that seabirds will be hooked and drowned in longline fisheries increases when baited hooks sink slowly. Fishermen target different fishing depths by setting the mainline through a line shooter, which controls the tension (or slackness) in the line.
