Paleolimnology in the High Arctic – implications for the exploration of Mars
Read more of: Paleolimnology in the High Arctic – implications for the exploration of MarsPaleolimnology provides information on the past chemical, physical and biological nature of water bodies. In polar regions, where global climatic changes can be exacerbated compared with lower latitudes, the science […]

Climatic control of ultraviolet radiation effects on lakes
Read more of: Climatic control of ultraviolet radiation effects on lakesUltraviolet radiation (UVR) damages most biota, yet little evidence exists for its long-term effects on natural ecosystems. We used paleoecological techniques at three low-elevation lakes to show that algal abundance […]

An investigation into the correlation of geomagnetic storms with tropospheric parameters over the South Pole
Read more of: An investigation into the correlation of geomagnetic storms with tropospheric parameters over the South PoleWe test the proposal that the Sun’s magnetic activity, communicated via the solar wind, provides a link between solar variability and the Earth’s climate in the Antarctic troposphere. The strength […]

The Labrador Sea Deep Convection Experiment data collection
Read more of: The Labrador Sea Deep Convection Experiment data collection[1] Between 1996 and 1998, a concerted effort was made to study the deep open ocean convection in the Labrador Sea. Both in situ observations and numerical models were employed […]

Shedding new light on the life cycle of mackerel icefish in the Southern Ocean
Read more of: Shedding new light on the life cycle of mackerel icefish in the Southern OceanMackerel icefish have a widespread distribution in the Atlantic and Indian Ocean sectors of the low-Antarctic region. Biological characteristics differ considerably between populations in the southern Scotia Arc and those […]
