To properly characterize the atmospheric properties of a site for a future large telescope or interferometer, it is insufficient to … measure quantities, such as the full-width at half-maximum of a stellar image, that have been integrated over the entire … atmosphere.
We use satellite imagery from four sensors (Multi-angle Imaging SpectroRadiometer (MISR), Enhanced Thematic Mapper (ETM), and RADARSAT and ERS Synthetic Aperture Radar (SAR) to monitor the lengths of two rifts on the Amery Ice Shelf, from 1996 to 2004.
In order to improve our understanding of wintertime polar ozone losses, two ozonesonde Match campaigns were performed. The first one was carried out in the Arctic winter 2002/03. About 450 co-ordinated ozonesondes were launched from late November 2002 to March 2003.
To measure chemical induced ozone loss in the Arctic lower stratosphere the Match method was developed. Trajectory calculations based on stratospheric wind fields of the European Center of Medium-range Weather Forecasts (ECMWF) are used to track and to predict the ways of air parcels.
Abandoned waste dumps in Antarctica pose an environmental hazard due to contaminant … mobilisation in marine and terrestrial habitats. At Casey Station, east Antarctica, a shoreline … waste dump has contaminated adjacent marine sediments with metals, hydrocarbons and organic … carbon.
Abstract … A line transect marine science survey of the waters off East Antarctica (80°E-150°E; CCAMLR Division 58.4.1; IWC Areas IV &V) was conducted during the austral summer of 1995/96. A total of 350 hours search effort resulted in 342 sightings (746 animals)…
Mixing in Ellis Fjord, Vestfold Hills, East Antarctica, is controlled by processes influenced by the extent of ice formation. A study of water temperature and salinity as a site near the middle of the fjord was undertaken from May 1994 to February 1995 after a summer (1993-94)…
In order to improve our understanding of the January losses of ozone in the Arctic vortex two ozonesondes Match campaigns are scheduled within the project "Quantitative Understanding of Ozone losses by Bipolar Investigations" (QUOBI).
The International Whaling Commission (IWC) and Southern Ocean Global Ocean Ecosystem Dynamics (SO GLOBEC) program are collaborating on an ecosystem approach to understand baleen whale distributions in Antarctica.
The first three cruises in the 'year round' Southern Ocean GLOBEC series for 2001-2002 were conducted from March - June 2001. International Whaling Commission researchers participated in all three cruises (Gould LMG 01-03 USA mooring cruise…
Preliminary results from the IWC collaborative studies conducted on the 2001 winter survey and the 2002 late summer mooring cruise with the US SO GLOBEC program are presented. Sea-ice cover was significantly more extensive earlier in the season in 2002.
Seasonal surface water nitrate and phosphate depletions were calculated for the Subantarctic Zone (SAZ) and Polar Frontal Zone (PFZ) of the Southern Ocean along the World Ocean Circulation Experiment SR3 repeat section south of Tasmania, Australia, and three other transects slightly to the west.
This is a report containing results of desk studies and field investigations at Cape Denison produced for the AHC as a result of a National Estate Grant awarded to the authors in 1995. The Terms of Reference define three main areas of outcomes: 1.
To determine the foraging space of Emperor penguins Aptenodytes forsteri in winter 12 females from Auster colony (13 400 pairs) were equipped with satellite transmitters and time-depth recorders before departing on their 77 ± 8 d winter (June-August) foraging trip.
