Everything south of 60°S is considered the Antarctic. This means that the Antarctic consists not just of the continent, but also the surrounding islands, seas, and ice shelves.
No people live in Antarctica, although researchers and tourists do visit for some or all of the year.
Because Antarctica was isolated from the surrounding land masses for many millions of years, it has large areas of untouched natural environment. Preserving the region and its unique environment is also valuable from a research standpoint.
Permit is required to visit Antarctica
The Swedish Antarctic Act (2006:924) was enacted to provide the Antarctic with more robust environmental protection. It regulates all Swedish presence and activities south of 60°S. All Swedes wishing to travel to Antarctica, or engage in any form of activity there, must have a valid permit. Swedish citizens, Swedish naturalised citizens, and citizens of other countries living and working in Sweden must apply for a permit.
The Swedish Polar Research Secretariat is the agency that issues such permits to Swedish citizens, pursuant to the Swedish Antarctic Act (2006:924).
