The Southern Ocean is largely a High Nutrient Low Chlorophyll (HNLC) region where macronutrient concentrations are high and phytoplankton productivity is low. However, there are productive ‘hot spots’ that sustain […]
[1] Recently, Robinson et al. [2000] presented a brief report on the artificial generation of ULF waves by high power ionospheric modification and their subsequent detection by the Fast Auroral […]
Cold tolerant polar terrestrial arthropods have evolved a range of survival strategies which enable them to survive the most extreme environmental conditions (cold and drought) they are likely to encounter. […]
We welcome the development of the debate about structures at the surge-type glacier Kongsvegen, Svalbard. Our paper (Woodward et al., 2002) tested a number of hypotheses proposed in the literature […]
Ground penetrating radar (GPR) is a popular technique for imaging and interpreting sedimentary architecture. However, current literature shows a wide range in the quality of information provided on the GPR […]
Acoustic surveys for biomass estimation require accurate identification of echoes from the target species. In one objective technique for identifying Antarctic krill, the difference between mean volume-backscattering strength at two […]
1] Lower thermospheric and upper mesospheric rotational temperatures have been derived from ground-based measurements of the O-2(0-1) and OH(6-2) nightglow emissions over Resolute Bay, Canada ( 74.68degreesN, 94.90degreesW) and OH(4-2) […]
The sea ice surface, not open water, is the dominant source of sea salt to aerosol and ice cores in coastal Antarctica. Here, we show that it may also form […]
To an observer from space, the growth and retreat of the white ring of sea ice around Antarctica would be one of the clearest signs that Earth’s climate varies on […]
The Antarctic Peninsula is the largest of ~ twelve micro-continental fragments between southern South America, East Antarctica, and New Zealand. Their original positions and movement history following Gondwana breakup are […]
