	Antarctic Exploration -Baltimore Sun - Feb. 9, 1898

		In the nineteenth century, the Southern Ocean surrounding the Antarctic continent was prized as a source of wealth in the form of whale or seal oil and blubber.
		Some consider it to be the continent itself, and there is debate as to whether the floating ice shelves that are seaward extensions of the continental ice sheet form an integral part of the 'land' surface of the continent.
		These range from factual, data-driven entries such as biographies, wildlife details, and statements about national Antarctic programmes, to longer, thematic overviews on major themes, to analytical discussions of issues that are of significant interest both to scientific researchers and the general public, such as climate change, conservation, geopolitics, biogeography, and pollution.

		The Antarctic Treaty, signed during mounting Cold War tensions, successfully banned all military activity, nuclear testing, and the dumping of radioactive materials on the continent.
		Because the Bahia Paraiso spill was reportedly the first known accident of its kind in the Antarctic region, the accident alarmed environmental groups, which viewed the incident as a foreshadowing of future accidents if trends in tourism and ship transport were to continue at their current pace along the continental fringe.

	Histoire Antar/FR/Introduction
		These were in effect the readings made by the crew of Adrien de Gerlache who were the first to draw the clear distinction between the cold surface water, the warmer deeper water and the icy water at the bottom of the ocean.
		Before that, Antarctic oceanography had already taken its first steps at the time of the campaign of the English vessel Challenger (the first steamship to penetrate beyond the Antarctic circle) which left the United Kingdom in December 1872 for a three-year voyage covering some 70,000 nautical miles.
		It was to concern itself with, among other things, the temperatures of the water, the circulation of the currents and the penetration of the light, both at the surface and in deep water.

		It is interesting to understand the significance of the Antarctic Circle and its relation to the hours of daylight.
		The Antarctic Circle is located at about 66º33'S (its position varies very slightly from year to year, as the earth wobbles about its axis).
		This circle marks the northernmost point at which the sun is visible for 24 hours a day at the summer solstice, on December 21, when it is at its highest point above the horizon.

		Today was the Antarctic Circle crossing ceremony, which meant that all us pollywogs were in for some serious abuse at the hands of King Neptune and our veteran cruisers.

	Antarctic History
		He was also the first Antarctic conservationist, noting that with a little sensible management the South Shetland fur seal population could have provided a sustainable annual harvest of about 100,000 skins.
		He also made two other notable contributions to Antarctic geography and navigation: he informed the Hydrographer in London that the headlands he had seen were certainly those of a continent, and he advised all future voyagers that the prevailing winds in very high latitudes blow east to west.
		The Antarctic never came back to pick them up, though, and they were forced to spend the winter of 1903 in dismal conditions.

	When did the Antarctic ice sheet form ? (Site not responding. Last check: )
		Most of Antarctica lay within the Antarctic Circle and there were long periods of darkness.
		The major geographical and oceanographic changes, brought about by the disintegration of Gondwana, which led to the eventual inception of the Antarctic Circumpolar Current in the Southern Ocean around 23 million years ago, were critical in hastening and reinforcing the cooling of the climate and the build up of ice.
		Glacial debris, dropped from icebergs, found in marine sedimentary rocks exposed in the South Shetland Islands, together with evidence from marine cores drilled from the sea bed suggest that there were significant ice sheets extending to the coastal fringes of Antarctica by 30 million years ago.
