Cook Bay (South Georgia)
Cook Bay () is an irregular bay, wide at its entrance between Cape Crewe and Black Head, narrowing into two western arms, Lighthouse Bay and Prince Olav Harbour, along the north coast of South Georgia. It was charted by Discovery Investigations (DI) personnel during the period 1926–30, and named by them for Captain James Cook, who explored South Georgia and landed in this general vicinity in 1775. Features The following notable features of Cook Bay were named by DI personnel, unless otherwise noted. Cape Crewe forms the north side of the entrance to Cook Bay. Cape Crewe is an established name, dating back to about 1912. Crewe Rock, an offshore rock about high, lies 0.1 nautical miles (0.2 km) east of Cape Crewe, for which it is named. Kelp Bank is a shoal, covered with kelp, lying northeast of Cape Crewe. The name appears to be first used on a 1931 British Admiralty chart. A small rock group referred to as the Olav Rocks lies east-southeast of Cape Crewe. It was name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Head (South Georgia)
Possession Bay is a bay wide on the north coast of South Georgia, an island in the southern Atlantic Ocean. It recedes southwest for , and is separated from Cook Bay to the north by Black Head promontory. It is connected to King Haakon Bay by Shackleton Gap, a mountain pass. Geography Several features in and around Possession Bay have been charted by various Antarctic expeditions. Black Head is a dark, rugged promontory, high, which separates Possession Bay from Cook Bay, to the north. At the head of the bay, Inner Reef extends from the headland Adventure Point on the west side of the bay to Brown Point on the east side. Just south of Adventure Point is Brighton Beach, which extends to Zero Point. Zero Point sits at the north side of Assistance Bay, a small bay within the larger Possession Bay. On the east side of the bay, Alert Point marks the mouth of Purvis Glacier. Outer Moraine Reef extends from Alert Point to Steep Point. Brown Point sits between Steep Point and Gla ...

Prince Olav Harbour
Prince Olav Harbour is a small harbour in the south west portion of Cook Bay, entered between Point Abrahamsen and Sheep Point, along the north coast of South Georgia. Background Throughout the 19th century, South Georgia was a sealers' base and, in the following century, became a whalers' base. Prince Olav Harbour is the site of one of the seven main whaling bases established on South Georgia. Prince Olav Harbour was the location of a former Norwegian whaling station operational dating from 1911. History The whaling station was initially a floating factory site, a shore station being set up in 1916. The whaling station continued as a shore station until March 1931 and then was closed. The name was in use as early as 1912 and was given by Norwegian whalers for Olav V of Norway. The wreck of the ship ''Brutus'' remains, semi-submerged, where she was deliberately beached to serve as a coaling station. The ship was built in Glasgow in 1883 as the ''Sierra Pedrosa'', and measu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Discovery Investigations
The Discovery Investigations were a series of scientific cruises and shore-based investigations into the biology of whales in the Southern Ocean. They were funded by the British Colonial Office and organised by the Discovery Committee in London, which was formed in 1918. They were intended to provide the scientific background to stock management of the commercial Antarctic whale fishery. The work of the Investigations contributed hugely to our knowledge of the whales, the krill they fed on, and the oceanography of their habitat, while charting the local topography, including Atherton Peak. The investigations continued until 1951, with the final report being published in 1980. Laboratory Shore-based work on South Georgia took place in the marine laboratory, Discovery House, built in 1925 at King Edward Point and occupied until 1931. The scientists lived and worked in the building, travelling half a mile or so across King Edward Cove to the whaling station at Grytviken to work on w ...

James Cook
James Cook (7 November 1728 Old Style date: 27 October – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the British Royal Navy, famous for his three voyages between 1768 and 1779 in the Pacific Ocean and to New Zealand and Australia in particular. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand. Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755. He saw action in the Seven Years' War and subsequently surveyed and mapped much of the entrance to the St. Lawrence River during the siege of Quebec, which brought him to the attention of the Admiralty and the Royal Society. This acclaim came at a crucial moment for the direction of British overseas exploration, and it led to his commission in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoal
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kelp
Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant - it is a heterokont, a completely unrelated group of organisms. Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. The organisms require nutrient-rich water with temperatures between . They are known for their high growth rate—the genera ''Macrocystis'' and '' Nereocystis'' can grow as fast as half a metre a day, ultimately reaching .Thomas, D. 2002. ''Seaweeds.'' The Natural History Museum, London, p. 15. Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate). The seaweeds used included species from both the orders Laminariales and Fucales. The word "kelp" was also used directly to refer to these processed ashes. Description In most kelp ...

British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strait
A strait is an oceanic landform connecting two seas or two other large areas of water. The surface water generally flows at the same elevation on both sides and through the strait in either direction. Most commonly, it is a narrow ocean channel that lies between two land masses. Some straits are not navigable, for example because they are either too narrow or too shallow, or because of an unnavigable reef or archipelago. Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both the two opposite strait exits, forming subaqueous fans or deltas. Terminology The terms ''channel'', ''pass'', or ''passage'' can be synonymous and used interchangeably with ''strait'', although each is sometimes differentiated with varying senses. In Scotland, ''firth'' or ''Kyle'' are also sometimes used as synonyms for strait. Many straits are economically important. Straits can be important shipping routes and wars have been fought for control of them. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
