Weddell seals spend much of their time below the Antarctic ice. They have the southernmost range of any seal, but find the chilly waters rich with the prey they seek. These seals do not migrate often and are commonly found within a few miles of their birthplace.

There are no native human populations in Antarctica. Only researchers and support staff from many different nations live there for a time while they are doing their work. Its not a particularly hospitable place.People live on the Antarctic continent because they have jobs representing their governments. Governments pursue science in Antarctica, and support scientists interested in the study the health of planet earth.There are no countries on Antarctica and no permanent population. Many countries have scientific research stations on Antarctica, most of which are only manned during the summer months.

Taking an icebreaker ship to Antarctica is an advantage. You have a quick form of transport, and if you get stuck in ice, the icebreaker part of the ship is there to help!

Chlorofluorocarbon gases (CFCs) take six or seven years to move up to the stratosphere and the winds spread them all round the world.Extreme cold, a freezing vortex wind, frozen stratospheric clouds and 6-month darkness over Antarctica all provide ideal conditions for chlorine to break from the CFCs.The chlorine (and bromine) gases destroy the ozone during spring (Sept to Dec) and this is what causes the ozone hole.More detail:Chlorofluorocarbon gases (CFCs) and related halocarbon gases are the main cause of ozone depletion all over the world. CFCs released from Western countries take several years to reach the stratosphere where the ozone layer is. During that time winds spread them all over the world. In the presence of ultraviolet light these gases release chlorine and bromine atoms which destroy some of the ozone in the ozone layer. This is called ozone depletion. The ozone hole is a related but different phenomenon. The hole is Antarctica occurs in the spring (September to December). It begins with this overall ozone thinning, but it is assisted by the presence of polar stratospheric clouds (PS clouds). During the extreme cold of winter, with no sun for six months, polar winds create a vortex which traps and chills the air; the temperature is below -80 Celsius. The ice in these PS clouds provides surfaces for the chemical reactions that destroy the ozone. This needs light to kick-start the reactions.In spring the sun rises above the horizon and provides energy which starts the photochemical reactions. The clouds melt and the trapped compounds (chlorine and chlorine monoxide from the CFCs) are released. Ozone in the lower stratosphere is destroyed and the ozone hole appears.By the end of spring warmer December temperatures break up the vortex and destroy the PS clouds. Sunlight starts creating ozone again and the hole begins to repair.(A similar hole in the Arctic [but smaller because of warmer temperatures] occurs during spring.)

The continent of Antarctica is located south of 60 degrees South Latitude, the far southern part of planet Earth. It covers 10% of the earths surface and is about as large as the US and Mexico combined. Antarctica is a continent located entirely in the Southern Hemisphere, and also located in both the Eastern and Western hemispheres.

Scientific expeditions have found valuable minerals in some of these Antarctic areas, including antimony, chromium, copper, gold, lead, molybdenum, tin, uranium, and zinc. None approach a grade or size warranting economic interest. Also noneconomic are the very large deposits of coal and sedimentary iron.

Scientists have even found deep-sea corals off the coast of Antarctica. They grow in all the worlds ocean basins, where they form deep-water havens on continental shelves and slopes, in ocean canyons, and on tall seamounts.
