This study analyzes geopotential height data from the ERA-40 and ERA-Interim reanalyses for the period of 1958–2009 to provide some new insights on the stratospheric Quasi-Biennial Oscillation (QBO) modulation of […]
Seabirds are facing a growing number of threats in both terrestrial and marine habitats, and many populations have experienced dramatic changes over past decades. Years of seabird research have improved […]
Most of the ice lost from the Antarctic ice sheet passes through a few fast-flowing and highly dynamic ice streams(1). Quantifying temporal variations in flow in these ice streams, and […]
Temperatures on the Antarctic Peninsula are increasing at a rate of 3.4°C per century, more than five times the global mean. At the same time, the region’s ice shelves have […]
Fuel oil has been extensively relied upon as an energy source since the earliest discovery and exploration of Antarctica. During this time oil spills have occurred, particularly around established research […]
Geomagnetic data from five northern hemisphere observatories at latitudes ranging from 22 degrees N to 67 degrees N have been used to investigate long-term trends in planetary wave activity in […]
Nitric oxide, which reacts catalytically to destroy ozone, can be produced in great abundance in the middle atmosphere during energetic particle precipitation triggered by solar storms. During the Antarctic winter, […]
By attaching 9-g loggers (recording dusk and dawn times to a memory chip) to the coded leg rings of Barnacle Geese Branta leucopsis caught in a breeding colony at Tobseda […]
We analysed summer diet and fledging mass of macaroni penguins Eudyptes chrysolophus breeding at Bird Island, South Georgia, during the crèche period (January and February) between 1989 and 2010. Crustaceans […]
The historic view of ice-bound ecosystems has been one of a predominantly lifeless environment, where microorganisms certainly exist but are assumed to be either completely inactive or in a state […]
