Port Foster
Port Foster, one of the safest harbours in the Antarctic, is a natural sheltered harbour in the form of a great scoop out o the heart of Deception Island in the South Shetland Islands, part of the British Antarctic Territory. It is formed of a drowned and breached volcanic crater, of the volcano which created the island.

History
The harbour was discovered by Nathaniel Palmer on 15 November 1820 and charted by Fildes in 1821. It was initially charted as 'Deception Harbour', but soon attracted the name Port Williams, after Captain William Smith's brig, the Williams, or Yankee Harbor, because of the number of American sealers who harboured there.
A little later the harbour was named 'Port' Foster after Henry Foster, commander of the HMS Chanticleer, who made pendulum and magnetic observations in this harbour in 1829. The latter name has become established by usage, while the former names have remained for other features in the same archipelago — Williams Point and Yankee Harbour.
The harbour was charted by a Royal Navy Hydrographic Survey Unit in 1948-49.
Description
The centre of Deception Island is a caldera, formed by a gigantic volcanic eruption and later flooded. This has created the basin-like harbour of Port Foster, six miles by four and a half miles in size. The entrance to Port Foster is only 610 yards wide and is named 'Neptune's Bellows'.
The benthic zone of Port Foster is of great ecological interest due to the natural disturbance induced by the volcanic activity. Two areas have been collectively protected as Antarctic Specially Protected Area (ASPA) No.145.[1]
The shores of the harbour were designated SSSI No. 21 under the Antarctic Treaty.[2]
