The taxonomic composition of the biota of the Coralline Crag Formation (early Pliocene, eastern England) provides conflicting evidence of seawater temperature during deposition, some taxa indicating cool temperate conditions by […]
Since at least the middle-Miocene, the Antarctic Polar Front (APF) and the Subtropical Front (STF) appear to have been the main drivers of diversification of marine biota in the Southern […]
The extreme conditions of life in Antarctica pose challenges to many organisms. Bryophytes comprise the main vegetation of the continent and they endure many adversities, thriving in an environment hostile […]
The vegetation of many terrestrial habitats across Antarctica is dominated by poikilohydric symbiotic lichens. Terrestrial habitats generally are characterised by extended exposure to desiccation and high irradiation. Physiological adaptation mechanisms […]
The substorm process releases large amounts of energy into the magnetospheric system, although where the energy is transferred to and how it is partitioned remains an open question. In this […]
Five post-tectonic granitic plutons isolated within the central Ellsworth-Whitmore mountains crustal block in West Antarctica form a distinctive geochemical suite. All have some characteristics of S-type granites and are atypical […]
The Antarctic Peninsula Mesozoic magmatic arc has had a long history of dextral, strike-slip deformation. The deformation was initially associated with the development of a wide accretionary complex, by the […]
Fabry-Perot interferometer Doppler measurements of the 6300 Å oxygen emission line have been used to determine the neutral thermospheric wind over Halley, Antarctica. Simultaneous measurements of the local magnetic field […]
The dynamics of the upper thermosphere in the southern polar cap, auroral, and mid‐latitude zones is reviewed. Information has been drawn from published measurements from the DE 2 and AE‐C […]
