Petermann Island (65°10′S 64°10′W / 65.167°S 64.167°W) is an island 1 nautical mile (1.9 km; 1.2 mi) long, lying 1 nautical mile (1.9 km; 1.2 mi) southwest of Hovgaard Island in the Wilhelm Archipelago, Antarctica.[1]
Location
[edit]
Petermann Island is off the Graham Coast of the Antarctic Peninsula. It is in the Wilhelm Archipelago, southwest of Hovgaard Island and Booth Island, east of the Vedel Islands and northeast of the French Passage. It is northwest of Mount Shackleton on the mainland.[2]
The island is 1.8 km (1.1 mi) long and 1.2 km (0.75 mi) across. It rises steeply to elevations of up to 250 m (820 ft) from a rocky coastline with raised pebble beaches. It has volcanic origins, with about half the land surface covered by a permanent, crevassed icecap. Ice-free areas have a sparse vegetation of mosses and lichens.[3] The bedrock of the island is granodiorite.[4]
Important Bird Area
[edit]
The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 3,000 pairs of gentoo penguins. Other birds nesting at the site in smaller numbers include Adélie penguins, imperial shags, Wilson's storm petrels and south polar skuas.[3]
Sailing directions
[edit]The US Defense Mapping Agency's Sailing Directions for Antarctica (1976) describes Petermann Island as follows:
PETERMANN ISLAND (Lund Island) 65°10'S., 64°09'W.) lies about 1 mile south-southwestward from Hovgaard Island, is about 1 mile in length and half as broad. Clayton Hill, a rocky mass 436 feet high, located in the northern portion of the Island, marks the highest elevation. An Iron post BEACON having a yellow and black banded cylindrical topmark stands on Clayton Hill. A beacon also stands on the southern end of the Island.
This peak is flanked on each side by low peninsulas deeply cut by small fiords. The Southwest fiord, although offering depths of 6.4m (3 1/2 fm) to 23.8m (13 fm) is not a favorable harbor because heavy swells enter as well as much drift ice. The ice cliffs at the head of the fiord frequently calve making the anchorage uncomfortable for vessels. The Ice cliffs offer no shore anchorage for moorings. The Northeast fiord offers depths of 15.5m (8 1/2 fm) but is open to prevailing winds, and ice blocks the fiord at each storm.
The eastern fiord Is called Port Circumcision (Port Circoncision), and It was here that Dr. Charcot wintered the Pourquoi Pas in 1909, Two shoals with 2.7m (1 1/2 fm) of water over them lie to northward and to southward of the entrance of the harbor but do not obstruct the entrance. Vessels entering should approach from the southeastward and steer to enter midway between the entrance points; the channel between the flanking shoals has a minimum depth of 8.2m (4 1/2 fm).
The harbor offers a shelter for small vessels which may be moored alongside the rocky shores in the head of the fiord, where depths of 5.5m (3 fm) to 8.2m (4 1/2 fm) are found. Vessels wintering in this site should moor by anchor cable to suitable points on the shore as well as taking anchorage underfoot. Barriers of chain should be erected across the harbor entrance to prevent damage to the vessel by drifting ice. At least one fathom of water should be kept under the vessel for waves several feet high have been experienced here as well as a strong undertow. The fiord is exposed to northeast winds, and is not recommended for winter quarters.
An Argentine station is located on the southern shore of Port Circumcision.[5]
History
[edit]Petermann Island was discovered by a German expedition 1873-74, and named by Eduard Dallmann for August Petermann, noted German geographer and founder of Petermanns Mitteilungen. The United States Advisory Committee on Antarctic Names (US-ACAN) has rejected the name Lund Island, applied by the Belgian Antarctic Expedition (BelgAE), 1897-99, in favor of the original naming.[1] The French Antarctic Expedition (FrAE) of 1908-10 under Jean-Baptiste Charcot wintered over aboard ship in a cove on the southeast side of the island, named Port Circumcision because it was spotted 1 January 1909, the traditional day for the Feast of the Circumcision.[6] Huts built by the expedition are gone, although a cairn remains, along with a refuge hut built by Argentina in 1955, and a cross commemorating three members of the British Antarctic Survey who died in a 1982 attempt to cross the sea ice from Petermann to Faraday Station.
Megalestris Hill Cairn
[edit]
A cairn with a lead plaque was erected on Megalestris Hill in 1909. The original plaque has since been removed to the Museum National d’Histoire Naturelle in Paris, but the cairn, with a replica plaque, has been designated a Historic Site or Monument (HSM 27), following a proposal by Argentina, France and the United Kingdom to the Antarctic Treaty Consultative Meeting.[7]
Groussac Refuge
[edit]Groussac Refuge (65°10′33″S 64°08′10″W / 65.175727°S 64.136247°W) is an Argentine naval refuge (originally called Hippolyte Bouchard) in Antarctica, located on the southern coast of the Port Circumcision, on Petermann Island. The refuge was inaugurated on February 6, 1955 and is operated by the Argentine Navy and was occupied periodically by personnel of the British Antarctic Survey of the former Faraday Station. The refuge is in the middle of a colony of Gentoo penguins. Its current name is in honour of Paul Groussac, a French writer and historian who lived in Argentina and authored a plea on the Argentine claim of the Malvinas Islands and biographies of Argentine national heroes.[citation needed]
