The atmospheric electric field Ez measured at the Antarctic Plateau station of Vostok made it possible to estimate … the role of the main generators in formation the global electric circuit. In the polar region during the periods with good … weather conditions the classical diurnal curve…
The temeperate glaciers of the sub-Antarctic islands are located on a cold, wet, maritime environments making them … valuable climatic indicators for the Southern Ocean. The changes in the glacier fronts on Heard, Kerguelen, Crozet, Marion, Bouvetoya, South Gerogia…
Because of the vast reservoirs of water mass held in the great ice sheets of Antarctica and Greenland, determining the … role that they play in global sea level has long been a major challenge of polar science. But until recent advances in … measurement technology…
Pressure variations at 11 Antarctic sites and 7 Arctic sites have been examined and … show significant correlations with a daily proxy for the output of the meteorological … generators of the global atmospheric circuit.
The role played by Southern Hemisphere sea-ice in global climate is explored using an … Earth system climate model of intermediate complexity.
A multi-directional telescope for detection of high-energy galactic cosmic rays (GCRs) - muons … was installed in 2001, through an international cooperation between Brazil, Japan and USA, and … operated since then at the Southern Space Observatory - SSO/CRS/INPE - MCT, (29S, 53W)…
Neutron monitors are integral detectors of secondary cosmic rays. Since each of them … has its own detection efficiency, energy spectra cannot readily be derived from their … observations. To circumvent this problem…
This paper presents results on modeling the ground-level response of the higher energy protons for the 2005 … January 20 ground-level enhancement (GLE). This event, known as GLE 69, produced the highest intensity of relativistic … solar particles since the famous event on 1956 February 23.
Between January and April over six consecutive years (2000 to 2005) photographs of the … dorsal fin and lateral bodies of pygmy blue whales (Balaenoptera musculus brevicauda) were … collected at the Perth Canyon, Western Australia.
Identification of DNA sequence diversity is a powerful means for assessing the … species present in environmental samples.
The application of blue-dye to fishing baits is a seabird bycatch mitigation technique used … in some pelagic longline fisheries that is thought to make the baits less visible and hence … less attractive to seabirds. We tested this assumption in two ways. First…
Airgun ‘shots’ from seismic surveys are powerful enough to be heard across ocean basins. At … close range, though, there is extraordinarily little understanding of the potential for these intense … sounds to cause temporary or permanent hearing threshold shifts (TTS/PTS) in marine … mammals.
The Antarctic Biodiversity Database developed and hosted by the Australian Antarctic Data Centre (AADC), holds data and information on Antarctic and subantarctic flora and fauna in support of the SCAR Life Sciences programme Evolution and Biodiversity in the Antarctic (EBA).
Modelled 10Be production by solar cosmic ray (SCR) events is compared with measured 10Be concentrations … in a Law Dome snow pit record. The snow pit record spans 2.7 years, providing a quasi-monthly 10Be … sampling resolution which overlaps with the SCR events of 29 Oct 2003 and 20 Jan 2005.
Seismic anisotropy is investigated across the previously unstudied region of central East Antarctica including new coastal locations and remote, temporary stations far inland.
A conceptual, lithospheric-scale cross-section of the conjugate, oblique-slip margins of George V Land, East … Antarctica, and southeast Australia (Otway Basin) has been constructed based on the integration of seismic and sample … data.
We present for the first time hourly variations of the spatial density gradient of 50 GeV cosmic rays within a sample … solar rotation period in 2006. By inversely solving the diffusive flux equation, including the drift…
Planetary waves with periods between two and four days in the middle atmosphere over … Antarctica are characterized using one year of data from the medium-frequency spaced … antenna (MFSA) radars at Scott Base, Rothera, and Davis. In order to investigate the origin … of the observed waves…
