Admiralty Sound

Geographical location

The Admiralty Street (English Admiralty Sound, Spanish Paso Almirantazgo (Chile), Estrecho Bouchard (Argentina ) ) is a strait about 75 km south of the tip of the Antarctic Peninsula. It runs from northeast to southwest and separates the James Ross Island in the northwest of the island of Seymour and Snow Hill Island in the southeast.

Geography

The Admiralty Road is about 55 km long, in the area of ​​Markham Bay about 20 km, in the southwestern part but only 5 km wide. At its exit to the Erebus and Terror Bay is the Cockburn Island, at the southwest exit to the Larsen Bay, the Lockyer Island. The banks of the Admiralty Street are heavily glaciated in the southwestern part, while the Seymour and Cockburn Island are free of snow in summer. All the islands in the area of ​​Admiralty Road are rich in animal and plant fossils from the Cretaceous and the Tertiary.

History

On January 6, 1843 James Clark Ross discovered the northern entrance into the road, which he called Admiralty Inlet. Only Otto Nordenskjold recognized as head of the Swedish Antarctic Expedition 1901-1903, that there is a road, not a sea inlet. He showed also the island character of Snow Hill and Cape Lockyer, who had already been spotted Ross. The discovery of the Prince Gustav Channel was also obvious that Mount Haddington is located on an island, the Nordenskjold gave the name of James Ross Island. The expedition wintered twice on the Snow Hill Island, where their cottage has been provided as a Historic Site No. 38 under the protection of the Antarctic Treaty. Your visit is highly regulated.

On the island of Seymour is located since 1969 with the Marambio station, the largest Argentine research station in Antarctica.
