Interleaving layers are commonly observed in the subsurface ocean near thermohaline fronts. They imply a lateral exchange of water mass properties and have been shown to influence both lateral and vertical mixing rates. We examine a set of in situ observations…
Aim … Polar and alpine plants live at the edge of their physiological limits. Thus, relatively small changes in climate can have disproportionate effects on biological and ecological processes. Antarctic mosses display highly variable micro-topography (canopy architecture)…

CryoSat-2 was launched in April 2010, as part of the European Space agency's (ESA) Earth Opportunity Programmes.
The joint TOT-Cal / CryoVExANT2011 project contributes to the validation of the CryoSat-2 altimetry mission through investigations of a key portion of the East Antarctic ice sheet near Australia’s Casey Station. Spanning parts of Law Dome and the Totten Glacier…
The TotCal / CryoVExANT2011 project is an Australian and German collaboration that contributes to the validation of the CryoSat-2 radar altimetry mission through investigations of a key portion of East Antarctica near the Australian Casey Station.
Glacier retreat has been widespread on Heard Island, an isolated 2745-m-high … volcano in the southern Indian Ocean, since the first observations in 1947. This study … represents the first quantification of the mass loss of a Heard Island glacier. Brown … Glacier is 4.

Macquarie Island is an oceanic island located 1000k m south-east of Tasmania.The island, which lies close … to but north of the Antarctic Convergence is the southern most island in the world with a fairly complete cover of … vegetation. However…
Middle-atmosphere gravity wave spectra of energy against vertical wavenumber are usually assumed to have a log-log slope of -3, based on a number of studies over many years and geographical locations, as well as from theoretical work.
Vertical geoelectric eld measurements at Vostok,Antarctica (78:5ºS ;107ºE;corrected geomagnetic latitude,83:4ºS) made during 1998 are compared with both Weimer (1996)and IZMEM (1994)model calculations of the solar-wind-induced, polar-cap potential di erences with respect to the station.
Between 1989/90 and 1994/95, geodetic GPS surveying techniques were used to measure ice sheet surface velocities at approximately 30 km intervals around an oversnow traverse route in the interior drainage basin of the Lambert Glacier, East Antarctica (longitude 54°-78°E, latitude 67°-76°S).
