The Adaptations of Antarctic Dinosaurs "Exploration Is the Physical Expression of the Intellectual Passion
The Adaptations of Antarctic Dinosaurs "Exploration is the physical expression of the Intellectual Passion. And I tell you, if you have the desire for knowledge and the power to give it physical expression, go out and explore. If you are a brave man you will do nothing: if you are fearful you may do much, for none but cowards have need to prove their bravery. Some will tell you that you are mad, and nearly all will say, "What is the use?" For we are a nation of shopkeepers, and no shopkeeper will look at research which does not promise him a financial return within a year. And so you will sledge nearly alone, but those with whom you sledge will not be shopkeepers: that is worth a good deal. If you march your Winter Journeys you will have your reward, so long as all you want is a penguin's egg." —Apsley Cherry-Garrard, "The Worst Journey in the World" Life Long Ago in the Antarctic Long ago during the age of the dinosaurs the basics of life and survival were not so different from today. Life was in great abundance and creatures of all sizes walked, stomped, crept and slunk all over the earth. Although many of the animals have changed and disappeared, the way all animals live have remained the same. They still need to eat, sleep and be safe. They still all strive to find way to raise a family and be happy. This was true even 185 million years ago in the continent we now call Antarctica. -
Argentine and Chilean Claims to British Antarctica. - Bases Established in the South Shetlands

The Foreign-Office in London, in statements on Feb. 7 and Feb. 13, announced that Argentina and Chile had rejected British protests, earlier presented in Buenos Aires and Santiago, against the action of those countries in establishing bases in British Antarctic territories. The announcement of Feb. 7 stated that on Dec. 7, 1947, the British Ambassador in Buenos Aires, Sir Reginald Leeper, had presented a Note expressing British "anxiety" at the activities in the Antarctic of an Argentine naval expedition which had visited part of the Falkland Islands Dependencies, including Graham Land, the South Shetlands, and the South Orkneys, and had landed at various points in British territory; that a request had been made for Argentine nationals to evacuate bases established on Deception Island and Gamma Island, in the South Shetlands; that H.M. Government had proposed that the Argentine should submit her claim to Antarctic sovereignty to the International Court of Justice for adjudication; and that on Dec. 23, 1947, a second British Note had been presented expressing surprise at continued violations of British territory and territorial waters by Argentine vessels in the Antarctic. -

The future is uncertain for Antarctica, with many possibilities – some more plausible, others more preferable. Indeed, the region and its governance regime may be reaching (or may have reached) a crossroads moment as a result of a series of challenges, including the changing Antarctic climate and environment, increasing human activity, shifting values among Antarctic states and a low-cost, somewhat benign governance regime (the Antarctic Treaty System). Within this context there are a number of interdependent drivers that are likely to influence Antarctica’s future over, say, 25 years: global environmental and socio-economic developments; Antarctic governance; Antarctic research, including national Antarctic programme operations; and Antarctic tourism. The research presented here involved a thorough examination of Antarctic literature on current Antarctic developments and challenges, and an assessment of global trends. -

Here we present palynological results from an Oligocene to Miocene sediment record provided by the Integrated Ocean Drilling Program Expedition 318 to the Wilkes Land margin (East Antarctica). The Oligocene assemblages (33.9-23 Ma) are dominated by pollen and spores from temperate forest and sub-Antarctic shrub vegetation inhabiting different altitudinal zones. These in- clude a lowland cold temperate forest with Dacrydium and Lagarostrobos (both common in southern forests of New Zealand and Tasmania today) and a high altitude tundra shrubland comprising Microcachrys, Nothofagus (southern beech) and Podocarpaceae conifers. -

Croce (Trieste), Italy, 4LSCE, CNRS Gif-sur-Yvette, Avenue de la Terrasse, Bat 12, Gif-sur-Yvette, 91198, France. Summary The IMAGES-CADO (Coring Adélie Diatom Oozes) research cruise targeted in 2003 the Adelie Land Coast, which lays seaward of one of the largest, marine-based sectors of the East Antarctic Ice Sheet (Wilkes Basin). It is also a site of production of the Adelie Land Bottom Water, which ventilates the deep ocean and contributes to the global thermohaline circulation. MD03-2603, a ~32 m long piston core, was collected on a sediment mound on the continental rise, with the aim of investigating the late-Quaternary depositional environment in relation to the past ice- sheet and oceanographic conditions. Geochemical/compositional information has been compared to isotopic, biostratigraphic and paleomagnetic data, leading to the identification of six glacial/interglacial climatic cycles in the sediment. -
