Repeat hydrographic sections occupied in 1995 and … 2005 reveal a rapid decline in the salinity and density of … Antarctic Bottom Water throughout the Australian Antarctic … Basin. The basin-wide shift of the deep potential … temperature-salinity (qS)…
The spatial and temporal characteristics of cyclonic eddies in the Antarctic … Divergence off Ade´lie Coast are described using repeated in situ observations between … 2001 and 2003, satellite observations, and results of a high-resolution ocean general … circulation model.
We describe the circulation and seasonal development of the upper ocean … in the Seasonal Ice Zone (SIZ) of the Southern Ocean along 140°E. The 140°E section … was repeated four times between November 2001 and March 2002, spanning the period … from early spring to autumn.
Repeat summer hydrographic observations along … 140E are used to document significant changes in the … properties of the Ade´lie Land Bottom Water (ALBW) between the mid-1990s and 2002–2003. Water on the 28.35 … kgm3 neutral density surface cooled by 0.2C and … freshened by 0.
Power spectral density (PSD) of cosmic rays has been calculated from hourly … averaged counts observed by underground muon telescopes located at Mawson over the … low-frequency range 2.7 ×10−7 –1.4 × 10−4 Hz. The first two harmonics of the solar daily … variation are well defined for even cycles…
The quasi-stationary asymmetry of total ozone … over Antarctica during spring is studied by TOMS data during … the period 1979–2005.
The Mansurov effect, which for the Southern Hemisphere consists of a positive … association between the By component (east-west) of the interplanetary magnetic field … (IMF) and the ground-level pressure for stations poleward of 80 magnetic latitude, is … confirmed for Vostok (78.5S, 106.
Extreme solar processes at the Sun on 2001April 15 accelerated protons to relativistic energies, resulting in a groundlevel … enhancement in cosmic rays observed at Earth. The GOES 10 spacecraft measured the proton flux directly…
Clean sediment collected from O’Brien Bay, East Antarctica, was artificially contaminated with a mix of Special Antarctic Blend diesel fuel and lubricating oil and deployed in two uncontaminated locations (O’Brien and Sparkes Bays) and a previously contaminated bay (Brown Bay)…
Previous studies of impacted sites near Casey Station, Antarctica, have revealed elevated concentrations of metals and metalloids, particularly Cd, Cu, Fe, Pb, Sn and Zn in marine sediments. However…
A hot water drill was used to penetrate 480 m of ice to reveal a diverse benthic assemblage, dominated by … suspension-feeding invertebrates, under the Amery Ice Shelf (East Antarctica) at a location 100 km from open … water and at a depth of 775 m below sea level (840 m below the ice shelf surface)…
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.
An assessment of the glaciological and meteorological characteristics of Dome A, the … summit of the East Antarctic ice sheet, is made based on field investigations during the austral summer of … 2004/05.
