Lack of foraminiferal carbonate in marine sediments deposited at high latitudes results in traditional oxygen isotope stratigraphy not playing a central role in Quaternary age control for a large portion […]
The lithospheric structure of Antarctica is still under‐explored. Moho depth estimate studies are in disagreement by more than 10 km in several regions, including for example the hinterland of the […]
The Circumpolar Biodiversity Monitoring Programme (CBMP) provides an opportunity to improve our knowledge of Arctic arthropod diversity, but initial baseline studies are required to summarise the status and trends of […]
Travelling ionospheric disturbances with periods in the range 10 < τ < 30 min were observed by an HF Doppier network on the Antarctic Peninsula. A distinction was made between […]
Six island or island groups (Marion and Prince Edwards Islands, Iles Crozet, Iles Kerguelen, Heard and McDonald Islands, Macquarie Island, South Georgia) are considered in this account to belong to […]
The Maritime and Continental Antarctic terrestrial ecosystems are considered in the context of environmental impacts-habitat destruction, alien introductions, and pollution. Their ability to recover from perturbation is discussed in the […]
Present threats to Antarctic seabirds and seals when ashore include disturbance and habitat destruction (some directly caused by humans; most through the introduction of rabbits and other grazers; also seal […]
Exploitation of minerals either from continental shelves or land areas free of ice has yet to take place in the Antarctic. The paper considers pressures, commercial, strategic, and possible depletion […]
Throughout the late Mesozoic a distinctive bivalve fauna can be traced around the southern Gondwana margins. It is characterized by inoceramids (Retroceramus, Inoceramus, Anopaea), oxytomids (Malayomaorica, Arctotis, Aucellina, Maccoyella), and […]
