Port Foster



Port Foster is one of the safest harbours in Antarctica, located in Deception Island in the South Shetland Islands.

History
The harbour was known to sealers as early as 1820, and in its early history was called Port Williams, after Captain William Smith's brig, Williams; or Yankee Harbor, because of the number of American sealers who harboured there.

The port, briefly called Yankee Harbour and Port Dunbar, was named Port Foster after Henry Foster, captain of HMS Chanticleer (1808) and leader of the first scientific expedition to the island in Jan.-March 1829. The expedition, based in Pendulum Cove, made gravitational and magnetic measurements, produced the first topographic map, made temperature measurements, and made a hydrographic survey.

Former names for the port have remained for other features in the same archipelago — Williams Point and Yankee Harbor.

Description
The centre of Deception Island is a caldera, formed by a gigantic volcanic eruption and later flooded. This has created the 10 by basin-like harbour of Port Foster. The entrance to Port Foster is only 560 m 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.
