The daily amplitude of the solar quiet (Sq) magnetic variation of the horizontal intensity, H, of observatories at low and midlatitudes is analyzed, in search of significant long-term trends. These […]
We present an update of the ‘key points’ from the Antarctic Climate Change and the Environment (ACCE) report that was published by the Scientific Committee on Antarctic Research (SCAR) in […]
Deriving glacier outlines from satellite data has become increasingly popular in the past decade. In particular when glacier outlines are used as a base for change assessment, it is important […]
Despite the dominance of cyanobacteria in polar freshwater aquatic ecosystems, little is known about their past biodiversity and response to climate and environmental changes. We explored the use of light […]
Moult entails costs related to the acquisition of energy and nutrients necessary for feather synthesis, as well as the impact of reduced flight performance induced by gaps in the wing […]
Although the Arctic occupies less than 5% of the Earth’s surface, it includes some of the strongest positive feedbacks in the climate system. Reconstructing the climate history of the Quaternary […]
Miniature geolocator loggers (Global Location Sensing, GLS) that provide daily locations of birds have revolutionised the study of winter ecology and migration patterns of seabirds. A long-term study of ringing […]
At all but the lowest latitudes, photoperiod varies through the year, resulting in seasonal variation in coastal primary productivity. This leads to a pronounced seasonality in the physiology of most […]
Electrical measurements of ice cores are used to obtain high time resolution records of past climate. The electrical conductivity method is sensitive to the acidity of the ice. The dielectric […]
We analyze data acquired by the CryoSat-2 interferometric radar altimeter and demonstrate its novel capability to track topographic features on the Antarctic Ice Sheet. We map the perimeter and depth […]
