Antarctica

Although several countries have laid claim to various portions of Antarctica, it is governed by the 1959 Antarctic Treaty [1],which establishes the continent as a peaceful and cooperative international research zone. There are no cities per se, just some two dozen research stations with a total population ranging from 1000-4000 depending on the time of year. These are maintained for scientific purposes only, and do not provide any official support for tourism. The laws of the nation operating each research station apply there. Private travel to Antarctica generally takes one of three forms: 1) commercial sea voyages with shore visits (by far the most popular), 2) specially mounted land expeditions, or 3) sightseeing by air. Approximately 80 companies belong to the International Association of Antarctica Tour Operators [2], a membership organization which regulates non-research travel to the region. In the 2005-2006 summer season, an estimated 26,250 people visited Antarctica or the surrounding waters.

Flora and fauna

Antarctica is notable for being the only continent with no native land mammals, reptiles, or amphibians. There are no polar bears: wrong pole. However its shoreline serves as nesting ground for many species of migratory birds and penguins, and the Southern Ocean surrounding it is home to many fish and marine mammals, including whales.

Landscape

Don't be fooled by all the ice: Antarctica is a desert. The region's moisture is all tied up in frigid seawater and the huge sheets, shelves, and packs of ice which cover nearly all of the continent plus surrounding waters. There is little snowfall here, and even less rain.

As most visitors to Antarctica will arrive by boat, the greatest dangers occur due to storms at sea. The weather in the Southern Ocean is nature at its most extreme, with the potential for hurricane force winds and waves as high as 60-70 feet (18-23 meters). With modern safety and ship design the odds of sinking are low, but the odds of being thrown about by a wave are high. Every year numerous people die or are seriously injured during the crossing to and from the continent. When on a boat in rough weather always make sure that you have at least one secure handhold, and avoid opening doors during storms as a sudden shift in the waves can easily bring a heavy door crashing back onto a body part. In severe weather stay in your cabin and wait for the storm to subside. Weather on the continent is equally extreme, although most visitors pack appropriate gear. For expeditions there are limited search-and-rescue options, so expeditions must plan for all contingencies. There is no formal government or legal system in Antarctica, but the laws of the country of origin or departure as well as those of a claimant government may apply. Rules regarding protection of the environment and of historical sites will be strictly enforced, and fines can be extreme.

Antarctica has an extreme environment. The cold is a major health hazard. Visitors should be properly prepared and equipped for any visit.
