Surveillance monitoring is important for detecting variations in species populations in response to natural and anthropogenic environmental changes. For seabirds this typically involves species-specific monitoring at breeding colonies.
Terrestrially breeding marine predators have experienced shifts in species distribution, prey availability, breeding phenology, and population dynamics due to climate change worldwide. These central-place foragers are restricted within proximity of their breeding colonies during the breeding season…
Changes in sea ice conditions and atmospheric circulation over the Southern Ocean play an important role in modulating Antarctic climate. However, observations of both sea ice and wind conditions are limited in Antarctica and the Southern Ocean, both temporally and spatially…
Black carbon (BC), the primary light-absorbing aerosol in the atmosphere, is emitted by the incomplete combustion of biomass and fossil fuels affecting the radiative balance of the atmosphere. As a contributor to climate change, BC may rival greenhouse gases such as methane.
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)…
The ICECAP project represents a return to the long-range, internationally collaborative … Antarctic aerogeophysics last seen in the 1970’s SPRI/NSF/TUD project. ICECAP is a joint … IPY collaboration between the University of Texas at Austin (funded by NSF), the University of … Edinburgh…
Over a decade of site testing in Antarctica has shown that both South Pole and Dome C are exceptional sites for … astronomy, with certain atmospheric conditions superior to those at existing mid-latitude sites. However, the highest … point on the Antarctic plateau, Dome A…
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…
This work contributes to the understanding of variation in methanesulphonic (MSA) concentration in an ice core … drilled during the 1996-97 Antarctic Campaign at the coastal plateau site of Talos Dome (East Antarctica)…
Firn core methanesulphonic acid (MSA) stratigraphy from Talos Dome (East … Antarctica) was compared with anomalies of the satellite-measured sea ice … extent (1973–1995) in the Ross Sea and Wilkes Land oceanic sector. In spite … of the sparseness of sea ice data…
We present the Gattini project: a multisite campaign to measure the optical sky properties above the two high altitude … Antarctic astronomical sites of Dome C and Dome A. The Gattini-DomeC project, part of the IRAIT site testing … campaign and ongoing since January 2006…
The Australian Antarctic Program’s iceberg dataset (from ship-based observations), including information from the austral summer seasons 1984/85 to 1999/2000, is examined and used … to extend earlier studies. Using ‘snapshots’ of the iceberg population to provide an idea of the iceberg … life cycle…
Abstract Since it is the largest glacier system in Antarctica, the Lambert Glacier basin plays an important role in the mass balance of the overall Antarctic ice sheet.
Recent data have shown that Dome C, on the Antarctic plateau, is an exceptional site for astronomy, with atmospheric conditions superior to those at any existing mid-latitude site. Dome C, however, may not be the best site on the Antarctic plateau for every kind of astronomy.
Oversnow traverses have collected a variety of glaciological measurements around the interior drainage basin of the Lambert Glacier, East Antarctica (longitudes 54°-78°E, latitudes 67°-76°S), between 1989-90 and 1994-95.
Methanesulphonic acid (MSA) measured along ice cores was largely used as a marker of … past marine biogenic activity because of it is formed by atmospheric oxidation of … dimethylsulphyde (DMS), emitted by metabolic processes of marine biota.
Dome A is the highest point on the surface of the East Antarctic ice sheet and the highest … ice feature in Antarctica. In January 2005 a team from the Chinese National Antarctic … Research Expeditions (CHINARE)…
Surface snow accumulation along the Chinese ITASE traverse line was measured using … bamboo stakes. Stakes along the initial (coastal) 300 km of the line were installed in 1997. The stake network was extended to 465 km in 1998, to 1100 km in 1999 and finally to 1228 … km (from the coast to Dome A)…
