Andersson Island
Andersson Island is a long and wide volcanic island of the James Ross Island Volcanic Group, located at the eastern end of the Tabarin Peninsula, Antarctica. The island was originally named Uruguay Island by the Swedish Antarctic Expedition, 1901–04, under Otto Nordenskjöld, after the Argentine ship Uruguay which participated in the rescue of the ship-wrecked Swedish Antarctic Expedition in 1903. It was ultimately renamed Andersson Island on November 21, 1949. It was named for Dr. Johan Gunnar Andersson (1874-1960), a Swedish geologist who had served on the Swedish Antarctic Expedition. The renaming was necessary to avoid confusion with Uruguay Island, located off the Graham Coast.

Antarctic Sound
The Antarctic Sound is a body of water about long and from wide, separating the Joinville Island group from the northeast end of the Antarctic Peninsula. The sound was named by the Swedish Antarctic Expedition under Otto Nordenskjöld for the expedition ship ''Antarctic'' which in 1902, under the command of Carl Anton Larsen, was the first vessel to navigate it. Since 1998 cruise ships have been visiting the area. Geography The Antarctic Sound is the stretch of water that separates Trinity Peninsula, the tip of the Antarctic Peninsula, from the Joinville Island group which consists of D'Urville Island, Joinville Island, Dundee Island and the smaller Bransfield Island. The northern limit of the sound, where it joins the Bransfield Strait, is the line connecting Cape Dubouzet (63°16'S, 57°03'W) on Trinity Peninsula with Turnbull Point (63°02'S, 56°36'W) on D'Urville Island. The southern limit is the line connecting Cape Scrymgeour on Andersson Island (63°35'S, 56°26'W) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joinville Island Group
Joinville Island group is a group of antarctic islands, lying off the northeastern tip of the Antarctic Peninsula, from which Joinville Island group is separated by the Antarctic Sound. Joinville Island, located at , is the largest island of the Joinville Island group.

Hope Bay
Hope Bay (Spanish: ''Bahía Esperanza'') on Trinity Peninsula, is long and wide, indenting the tip of the Antarctic Peninsula and opening on Antarctic Sound. It is the site of the Argentinian Antarctic settlement Esperanza Base, established in 1952. Important Bird Area The bay has been identified as an Important Bird Area (IBA) by BirdLife International because it supports one of the largest Adélie penguin colonies in Antarctica with around 125,000 pairs. Other birds nesting at the site include gentoo penguins, brown skuas, Antarctic terns, Wilson's storm-petrels, kelp gulls and snowy sheathbills. History The Bay was discovered on January 15, 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it in commemoration of the winter spent there by J. Gunnar Andersson and S.A. Duse, Toralf Grunden of his expedition after his ship (the '' Antarctic'') was crushed by the ice and lost. They were eventually rescued by Argentine corvette ''Uruguay''. Hop ...

Volcanic Island
Geologically, a high island or volcanic island is an island of volcanic origin. The term can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanos). Definition and origin There are a number of "high islands" that rise no more than above sea level, often classified as "islets or rocks", while some low islands, such as Banaba, Henderson Island, Makatea, Nauru, and Niue, as uplifted coral islands, rise over above sea level. The two types of islands are often found in proximity to each other, especially among the islands of the South Pacific Ocean, where low islands are found on the fringing reefs that surround most high islands. Volcanic islands normally arise above a hotspot. Habitability High islands above a certain size usually have fresh groundwater Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractu ...

James Ross Island Volcanic Group
The James Ross Island Volcanic Group is a stratigraphic unit of Cenozoic age distributed on James Ross Island and Vega Island of the James Ross Island group, the Tabarin and Trinity peninsulas of Graham Land and surrounding islands in the Prince Gustav and Antarctic sounds. The volcanic group consists predominantly of alkali basalts with minor hawaiites, benmoreites and mugearites. They are interpreted to have been deposited by volcanic eruptions in an extensional back-arc setting after subduction had ceased along the western margin of the Antarctic Peninsula. K–Ar dating of these rocks suggest that they were erupted from about 7 million years ago up until about a few hundred thousand years ago. However, volcanic rocks as young as only a few thousand years old may exist on James Ross Island. Rocks of the James Ross Island Volcanic Group comprise Surtseyan tuff cones and Strombolian cinder cones, as well as lava deltas and overlying subaerial lava flows. The dominating fe ...

Tabarin Peninsula
Tabarin Peninsula () is a peninsula 15 nautical miles (28 km) long and 5 to 12 nautical miles (22 km) wide, lying south of the trough between Hope Bay and Duse Bay and forming the east extremity of Trinity Peninsula in the Antarctic Peninsula. It was discovered and charted by the Swedish Antarctic Expedition, 1901–1904, led by Otto Nordenskjöld and Carl Anton Larsen. It was mapped in 1946 by the Falkland Islands Dependencies Survey (FIDS) and named after Operation Tabarin, the naval code name for the FIDS from 1943 to 1945. Geography The Tabarin Peninsula extends from the northernmost point of the Antarctic Peninsula southwards into the Weddell Sea for about . It is connected to the mainland by an isthmus about wide which lies between Hope Bay to the north and Duse Bay to the south. The average height of the peninsular is about and the highest point, at around , is Mount Taylor which lies just north of the isthmus. To the east of the peninsula lies the Antarctic ...

Swedish Antarctic Expedition
The Swedish Antarctic Expedition of 1901–1903 was a scientific expedition led by Otto Nordenskjöld and Carl Anton Larsen. It was the first Swedish endeavour to Antarctica in the Heroic Age of Antarctic Exploration. Background Otto Nordenskjöld, a Swedish geologist and geographer, organized and led a scientific expedition of the Antarctic Peninsula. The expedition's overall command was placed under the Norwegian Carl Anton Larsen, an experienced Antarctic explorer who served as captain of , and who had previously commanded a whaling reconnaissance mission in 1892–1893. Seven other scientists, including archaeologist Johan Gunnar Andersson, botanist Carl Skottsberg, and zoologist Axel Ohlin, along with 16 officers and men joined them on the voyage. On 16 October 1901, the ''Antarctic'' left the Port of Gothenburg. Events Despite its end and the great hardships endured, the expedition would be considered a scientific success, with the parties having explored muc ...
