This paper outlines the requirements of an ecosystem approach to the management of Southern Ocean resources and highlights the need for information on harvested and dependent species, their interactions and […]
The Antarctic Peninsula is one of the most rapidly warming regions on Earth, as evidenced by a recent increase in the intensity and duration of summer melting, the recession of […]
Metapelitic rock samples from the NE Shackleton Range, Antarctica, include garnet with contrasting zonation patterns and two age spectra. Garnet porphyroblasts in K-rich kyanite-sillimanite- staurolite-garnet-muscovite-biotite schists from Lord Nunatak show […]
Two-dimensional (2-D) statistical distributions of spectral power and coherence of polar geomagnetic variations with quasi-periods about 10 min are analyzed using data from magnetometer arrays in Antarctica. Examination of the […]
Knowledge about the areas used by the foraging wandering albatross, Diomedea exulans, its prey and overlap with longline fisheries is important information not only for the conservation of this species […]
The alpine cockroach Celatoblatta quinquemaculata is common at altitudes of around 1500 m on the Rock and Pillar range of Central Otago, New Zealand where it experiences freezing conditions in […]
One of our major aims as Earth systems scientists is to predict how the Earth will behave in the future, particularly in the face of changes imposed upon it as […]
In the clamour of predictions about future climate changes, it can be difficult to get hold of facts. However, by drilling ice cores from polar ice sheets and analysing them, […]
Geographical information Systems (GIS) provide tools for manipulating and analysing the large thematic datasets associated with Gondwana research. We have used a customised version of Environmental Systems Research Institute’s ArcGIS, […]
Bacteriochlorophylls c and d, recovered from two sedimentary sequences, were converted to bacteriophaeophorbide methyl esters by methanolysis and analysed by atmospheric pressure chemical ionisation liquid chromatography-multi-stage mass spectrometry (APCI LC-MSn). […]
A monospecific population of cypridinid ostracods (Myodocopida) has been recovered from an ammonoid-bearing concretion of Namurian (Kindescoutian, R1a-b) age in the Bowland Shale Formation of Central England. These deposits represent […]
