Aspects of the breeding biology of the whitc‐chinned petrel Procellaria aequinoctialis were studied at South Georgia. Laying, hatching and fledging dates, together with egg and adult measurements, rate of weight […]
A magnetospheric substorm that occurred at Sanae, Antarctica, on July 27, 1979, was observed by a variety of techniques. A synthesis of the observations is presented, and an attempt made […]
Linear belts 50–100 km in width of long-wavelength positive magnetic anomalies exceeding 500 nT are observed on continental blocks of the Scotia arc. The most developed is the West Coast […]
Organisms with long generation times require phenotypic plasticity to survive in changing environments until genetic adaptation can be achieved. Marine calcifiers are particularly vulnerable to ocean acidification due to dissolution […]
Reconstructions of the bedrock topography of Antarctica since the Eocene‐Oligocene Boundary (approximately 34 Ma) provide important constraints for modeling Antarctic ice sheet evolution. This is particularly important in regions where […]
The magmatic arc of the Antarctic Peninsula displays a wide range of features related to extensional tectonics at a convergent margin. Cenozoic extensional features are concentrated in a linear belt […]
The global solar radiation received at the earth’s surface in the presence of cloud depends not only on the optical depth of the cloud and its other physical properties, but […]
