[3] For example, an Australian traveling to Antarctica with a tourist company would need to show compliance with the Antarctic Treaty (Environment Protection) Act 1980 by means of an Environmental Impact Assessment (EIA) approved by the Australian Antarctic Division (AAD) of the Department of Agriculture, Water, and the Environment.
Sea cruises generally last anywhere between 10 days and 3 weeks and costs start from around US$6,000 per person for shared accommodation cabins.
However, in 2009, new regulations were enforced that stopped large vessels from operating in Antarctic waters due to their heavier fuel oils.
Later flights flew down the middle of the Sound and over Scott Base rather than over Ross Island as the aircraft could descend to a low altitude to provide better visibility for passengers[note 1].
Air New Zealand cancelled and never resumed their Antarctic flying programme in the aftermath of the TE901[note 2] disaster, where a route planning error led to the aircraft crashing into Mount Erebus on 28 November 1979 with the loss of all 257 lives aboard.
[citation needed] Qantas operated its first Antarctic flight on 13 February 1977, a charter organised by Sydney entrepreneur Dick Smith.
[9] Qantas also cancelled its Antarctic programme after the TE901 disaster but eventually resumed it in 1994, and continues to operate charter flights in summer from Sydney, Perth and Melbourne to this day with Boeing 747-400s.
[6] There were private yacht voyages in the Southern Ocean from the late 1960s, with some circumnavigations of Antarctica e.g. by David Henry Lewis in 1972.
[11] There are now about 30 yachts each year visiting the Antarctic Peninsula, which is in a banana belt (warmer region of the continent).
Guidelines have also been written for the organisers of tourist and private ventures - these require prior notification of the trip to the organiser's national authority (e.g. Antarctica NZ), assessment of potential environmental impacts, the ability to cope with environmental emergencies such as oil spills, self-sufficiency, the proper disposal of wastes and respect for the Antarctic environment and research activities.
Chile requires all captains of ships that go to Antarctica to attend a month-long school in Antarctic navigation.
Although visits are usually short, they are concentrated into a small number of landing sites and have the potential to destroy parts of a unique environment and to jeopardize scientific research.
