The Danco Coast ( 64°42′S62°0′W / 64.700°S 62.000°W ) is the portion of the west coast of the Antarctic Peninsula between Cape Sterneck and Cape Renard. This coast was explored in January and February 1898 by the Belgian Antarctic Expedition under Adrien de Gerlache, who named it for Lieutenant Emile Danco who died on the expedition. [1]
The coast is bordered by the Aguirre Passage which separates it from Lemaire Island. [2]
The Danco Coast Tectonic Block includes the Upper Permian-Triassic Trinity Peninsula Group, consisting of over 1000 m of metaturbidites folded during the Gondwanide orogeny. This group is overlain by the Lower Cretaceous Antarctic Peninsula Volcanic Group, with up to 2000 m of basaltic and andesitic lavas, tuffs and agglomerates, which were folded and faulted during the Tertiary. These two groups were intruded by the Berriasian-Cenomanian granite and gabbro sills of the Andean Instrusive Suite. A system of hypabbysal dykes intruded during the Late Cretaceous or Tertiary. [3]
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica.
Anvers Island or Antwerp Island or Antwerpen Island or Isla Amberes is a high, mountainous island 61 km long, the largest in the Palmer Archipelago of Antarctica. It was discovered by John Biscoe in 1832 and named in 1898 by the Belgian Antarctic Expedition under Adrien de Gerlache after the province of Antwerp in Belgium. It lies south-west of Brabant Island at the south-western end of the group. The south-western coastline of the island forms part of the Southwest Anvers Island and Palmer Basin Antarctic Specially Managed Area. Cormorant Island, an Important Bird Area, lies 1 km off the south coast.
Brabant Island is the second largest island of the Palmer Archipelago within the British Antarctic Territory, lying between Anvers Island and Liège Island. Brabant Island is 59 km (37 mi) long north-south, 30 km (19 mi) wide, and rises to 2,520 m (8,268 ft) in Mount Parry. The interior of the island is occupied by two mountain ranges, Solvay Mountains in its southern part and Stribog Mountains in its central and northern parts.
Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. The archipelago is in the British, Chilean, and Argentine Claims.
Lecointe Island is an elongated island, 7.27 km (4.52 mi) long between Cape Kaiser and Hvarchil Point, 2.2 km (1.4 mi) wide and 700 m (2,300 ft) high, separated from the east coast of Brabant Island by Pampa Passage, in the Palmer Archipelago, Antarctica.
Wilhelmina Bay is a bay 24 km wide along the west coast of Graham Land on the Antarctic Peninsula. It spans between the Reclus Peninsula to the northeast and Cape Anna to the southwest. It was discovered by the Belgian Antarctic Expedition of 1897–99 led by Adrien de Gerlache. The bay is named for Wilhelmina, Queen of the Netherlands, who reigned from 1890 to 1948. Wilhelmina Bay is a popular destination for tourist ships to Antarctica thanks to its scenery and abundant humpback whale population.
Charlotte Bay is a bay on the west coast of the Antarctic Peninsula indenting the west coast of Graham Land in a southeast direction for 12 nautical miles (22 km), between Reclus Peninsula and Cape Murray. Its head is fed by the glaciers Nobile, Bozhinov, Krebs, Wellman and Renard.
Gerlache Strait or de Gerlache Strait or Détroit de la Belgica is a channel/strait separating the Palmer Archipelago from the Antarctic Peninsula. The Belgian Antarctic Expedition, under Lt. Adrien de Gerlache, explored the strait in January and February 1898, naming it for the expedition ship Belgica. The name was later changed to honor the commander himself.
Rongé Island is a high, rugged island 8 km (5 mi) long, the largest island of the group which forms the west side of Errera Channel, off the west coast of Graham Land in Antarctica.
The Nordenskjöld Coast is located on the Antarctic Peninsula, more specifically Graham Land, which is the top region of the Peninsula. The Peninsula is a thin, long ice sheet with an Alpine-style mountain chain. The coast consists of 15m tall ice cliffs with ice shelves.
Neumayer Channel is a channel 16 miles (26 km) long in a NE-SW direction and about 1.5 miles (2.4 km) wide, separating Anvers Island from Wiencke Island and Doumer Island, in the Palmer Archipelago. The southwest entrance to this channel was seen by Eduard Dallmann, leader of the German 1873-74 expedition, who named it Roosen Channel. The Belgian Antarctic Expedition, 1897–99, under Gerlache, sailed through the channel and named it for Georg von Neumayer. The second name has been approved because of more general usage.
The Arctowski Peninsula is a peninsula, 15 miles (24 km) long in a north-south direction, lying between Andvord Bay and Wilhelmina Bay on the west coast of Graham Land. It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache. The name, for Henryk Arctowski of that expedition, was suggested by the Advisory Committee on Antarctic Names for this previously unnamed feature.
Neko Harbour is an inlet of the Antarctic Peninsula on Andvord Bay, situated on the west coast of Graham Land.
Vidbol Glacier is the 5.5 km long and 1.5 km wide glacier on Arctowski Peninsula on Danco Coast in Graham Land on the Antarctic Peninsula draining the north slopes of Pulfrich Peak. Flowing northwestwards west of Henryk Peak and east of Mount Dedo to enter Gerlache Strait at Orne Harbour.
Cape Sterneck is a bold, black cliff on a projecting point forming the west extremity of Chavdar Peninsula on the west coast of Graham Land, Antarctica. It is situated on the north side of the entrance to Hughes Bay and the west side of the entrance to Curtiss Bay, and separating Davis Coast to the northeast from Danco Coast to the southwest.
Metchnikoff Point is a point forming the western extremity of Pasteur Peninsula in northern Brabant Island, in the Palmer Archipelago, Antarctica. It was first charted by the Third French Antarctic Expedition, 1903–05, and named by Jean-Baptiste Charcot for Russian-born zoologist and bacteriologist Élie Metchnikoff, who succeeded Louis Pasteur as the director of the Pasteur Institute in Paris.
Hobbs Point is the northeastern end of Brooklyn Island in Wilhelmina Bay, off the west coast of Graham Land, Antarctica. It was charted by the Belgian Antarctic Expedition under Gerlache, 1897–99, and was named by the UK Antarctic Place-Names Committee in 1960 for Graham J. Hobbs, a Falkland Islands Dependencies Survey geologist at the Danco Island station in 1957 and 1958 who made a geologic reconnaissance survey of the coast between Cape Murray and Cape Willems.
Henryk Glacier is a glacier on Arctowski Peninsula, on the Danco Coast of Antarctica, with a noteworthy cirque at the head; it flows southwest between Wild Spur and Hubl Peak into Errera Channel. The glacier was named in association with the peninsula after Henryk Arctowski, by the Polish Antarctic Expedition, in about 1993.
Lemaire Island is an island 4.5 nautical miles (8 km) long and 1.5 nautical miles (3 km) wide, lying 1 nautical mile (2 km) west of Duthiers Point off the west coast of Graham Land, Antarctica. It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache, who named it for Charles Antoine Lemaire. The island is bordered by the Aguirre Passage which separates it from the Danco Coast.
The Antarctic Peninsula, roughly 1,000 kilometres (650 mi) south of South America, is the northernmost portion of the continent of Antarctica. Like the associated Andes, the Antarctic Peninsula is an excellent example of ocean-continent collision resulting in subduction. The peninsula has experienced continuous subduction for over 200 million years, but changes in continental configurations during the amalgamation and breakup of continents have changed the orientation of the peninsula itself, as well as the underlying volcanic rocks associated with the subduction zone.
