Chlorophyll fluorescence was used to measure changes in the maximum fluorescence yield (F0m) and effective quantum yield (F/F0m ) of Antarctic macroalgae in response to dissolved copper.
The Super Dual Auroral Radar Network (SuperDARN) is an international network of oblique HF over-the-horizon … radars dedicated to the study of high latitude magnetosphere-ionosphere convection. In scientific terms, they have been … an outstanding success…
Although long-range atmospheric transport has been described as the predominant mechanism … for exposing polar regions to persistent organic pollutants (POPs), recent studies have suggested … that bird activity can also contribute substantially to contaminant levels in some environments. However…
Reports of a variety of meteorological responses to short-term changes in the global electric circuit … associated with a number of disparate inputs are analyzed. The meteorological responses consist of changes in cloud … cover, atmospheric temperature, pressure, or dynamics.
The Mansurov effect, which for the Northern Hemisphere consists of a negative association … between the By component (east-west) of the Interplanetary Magnetic Field (IMF)…
Sea-ice drift and deformation in the Western Weddell Sea during austra; summer of 2004 are characterised using in situ data from a meso-scale array of 24 drifting ice buoys. About 30 days of data during late November and December 2004 are available from the buoy array.
This study presents compelling evidence for a diverse and abundant seabed community … that developed over the course of the Holocene beneath the Amery Ice Shelf, East Antarctica. Fossil … analysis of a 47 cm long sediment core revealed a rich modern fauna dominated by filter feeders …
Airborne, ship-borne and surface low-frequency electromagnetic (EM) methods have … become widely applied to measure sea-ice thickness. EM responses measured over sea ice depend … mainly on the sea-water conductivity and on the height of the sensor above the sea-ice–sea-water … interface…
