Croft Bay
Croft Bay () is a bay which indents the north-central side of James Ross Island and forms the southern part of Herbert Sound, south of the northeastern end of the Antarctic Peninsula. Location Croft Bay deeply indents the north shore of James Ross Island, which lies to the southwest of Trinity Peninsula, at the tip of the Antarctic Peninsula in Graham Land. The bay opens into Herbert Sound, to the north, which separates in from Vega Island. The Ulu Peninsula defines its west margin. Exploration and name Croft Bay was discovered in 1903 by the Swedish Antarctic Expedition under Otto Nordenskiöld. It was charted in 1945 by the Falkland Islands Dependencies Survey (FIDS), who named it for William Noble Croft, a FIDS geologist at Hope Bay in 1946. Features Blancmange Hill .

James Ross Island
James Ross Island () is a large island off the southeast side and near the northeastern extremity of the Antarctic Peninsula, from which it is separated by Prince Gustav Channel. Rising to , it is irregularly shaped and extends in a north–south direction. Location James Ross Island is separated from Trinity Peninsula, at the tip of the Antarctic Peninsula to the northwest, by the Prince Gustav Channel. Vega Island is to the north of the island, separated from James Ross Island by the Herbert Sound. Erebus and Terror Gulf is to the northeast. Seymour Island and Snow Hill Island are to the southeast. It is in the James Ross Island group. The island was connected to the Antarctic mainland by an ice shelf until 1995, when the ice shelf collapsed, making the Prince Gustav Channel passable for the first time. Mendel Polar Station, the first Czech Antarctic Base, is located on the island. Exploration and name James Ross Island was charted in October 1903 by the Swedish Antarct ...

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F ...

Dobson was an important figure in the Board of Agriculture and Fisheries, later known as the Ministry of Agriculture and Fisheries. He later served as the secretary of the International Whaling Commission from 1949 to 1959 and the president of the International Council for the Exploration of the Sea from 1952 to 1955. As a cricketer, he made one first-class appearance for the Gentlemen of England. Early life and civil service career The son of the poet Henry Austin Dobson, he was born at Ealing in June 1885 and was raised with a strict upbringing in the Plymouth Brethren. He was educated at Clifton College, before going up to Emmanuel College, Cambridge. While studying at Cambridge, he made a single appearance in first-class cricket for the Gentlemen of England against Surrey at The Oval in 1905. Batting twice in the match, he was dismissed in the Gentlemen of Engl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
International Whaling Commission
The International Whaling Commission (IWC) is a specialised regional fishery management organisation, established under the terms of the 1946 International Convention for the Regulation of Whaling (ICRW) to "provide for the proper conservation of whale stocks and thus make possible the orderly development of the whaling industry". As the decision-making body of the convention, the IWC reviews and revises measures laid down in the "Schedule to the Convention", which govern the conduct of whaling throughout the world. These measures include: confer complete protection of certain species; designate specific areas as whale sanctuaries; set limits on the numbers and size of whales which may be taken; prescribe open and closed seasons and areas for whaling; and prohibit the capture of suckling calves and female whales accompanied by calves. The Commission also mandates the compilation of catch reports and other statistical and biological records, and is actively involved in whale res ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Tuya
A tuya is a flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet. They are rare worldwide, being confined to regions which were covered by glaciers and had active volcanism during the same period. As lava that erupts under a glacier cools very quickly and cannot travel far, it piles up into a steep-sided hill. If the eruption continues long enough, it either melts all the ice or emerges through the top of the ice and then creates normal-looking lava flows that make a flat cap on top of the hill. Discovering and dating the lava flows in a tuya has proven useful in reconstructing past glacial ice extents and thicknesses. Formation Tuyas are a type of subglacial volcano that consists of nearly horizontal beds of lava capping outward-dipping beds of fragmental volcanic rocks, and they often rise in isolation above a surrounding plateau. Tuyas are found in Iceland, British Columbia, the Santiam Pass region in Oregon, the Tuva, Tyva Republic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

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 fea ...
