History
The harbour was known to sealers as early as 1820, and in its early history was called Port Williams, after Capt. William Smith's brig, the Williams, or Yankee Harbor, because of the number of American sealers who harboured there.
A few years later it 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 have remained for other features in the same archipelago — Williams Point and Yankee Harbor.
Description
The center of Deception Island is a caldera, formed by a gigantic volcanic eruption and later flooded. This has created the 10 by 7 km (6.2 by 4.3 mi) basin-like harbour of Port Foster. The entrance to Port Foster is only 560 m (1,840 ft) 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.
