The Scotia Are, linking the Magellan region with the Antarctic Peninsula, comprises young and old islands both near continents and isolated, and is the only semi-continuous link between cool temperate […]
We estimated a weakening of the Southern Ocean carbon dioxide (CO2) sink since 1981 relative to the trend expected from the large increase in atmospheric CO2. We agree with Law […]
In the upper atmosphere, greenhouse gases produce a cooling effect, instead of a warming effect. Increases in greenhouse gas concentrations are expected to induce substantial changes in the mesosphere, thermosphere, […]
Dust can affect the radiative balance of the atmosphere by absorbing or reflecting incoming solar radiation(1); it can also be a source of micronutrients, such as iron, to the ocean(2). […]
Several studies suggest that assemblages in intertidal zones that experience frequent physical extremes (e.g. wave-impacts) should be highly dependent on the regional input of propagules. Therefore with higher disturbance in […]
For many locations around the globe some of the most severe weather is associated with outbreaks of cold air over relatively warm oceans, referred to here as marine cold-air outbreaks […]
We conducted a seismic and radar survey of the central part of midtre Lovenbreen, a small, polythermal valley glacier in Svalbard. We determined the physical properties of the material beneath […]
The foremost temporal signal to the deep benthos, where temperature and light conditions are relatively constant, is a seasonal pulse of organic carbon sinking from the photic layer. In the […]
Direct time-series observations of deep-sea biological activity are largely restricted to passive observations of benthic epifauna using unbaited time-lapse camera systems. However, highly mobile fauna such as scavenging fish are […]
Continuous flow analysis (CFA) is a well-established method to obtain information about impurity contents in ice cores as indicators of past changes in the climate system. A section of an […]
