Milward Patch
Milward Patch is a large patch of kelp north of the eastern part of Bird Island, off the western tip of South Georgia. It was charted in 1930, along with other navigational hazards, by Discovery Investigations personnel on the ''William Scoresby'', and named for C.A.

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 mo ...

Bird Island, South Georgia
Bird Island ( es, Isla Pájaro) is long and wide, separated from the western end of South Georgia by Bird Sound. It is part of the British overseas territory of South Georgia and the South Sandwich Islands, also claimed by Argentina as part of Tierra del Fuego province. History It was discovered in 1775 by a British expedition under James Cook, who so named it "on account of the vast numbers f birdsthat were upon it". In the late 1950s, the island was the subject of a number of US-funded projects. Between 1959–62, a great number of the island's wandering albatross were ringed, which gave startling data about their range - one bird was found in Australia. The island is currently a Site of Special Scientific Interest, and so there are no landings allowed without permission. The summit of the island, Roché Peak, is named after the Englishman Anthony de la Roché who discovered South Georgia in 1675. Farewell Point forms the northeast extremity of Bird Island.

South Georgia
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. The main se ...

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 ...

RRS William Scoresby
RRS ''William Scoresby'' was British Royal Research Ship built for operations in Antarctic waters. Specially built for the Discovery Committee by Cook, Welton & Gemmell of Beverley, the ship was launched on 31 December 1925, and named after the noted 19th-century Arctic explorer, scientist and clergyman. Over the next 12 years the ship made seven voyages into Antarctic waters as part of the Discovery Investigations, accompanied by the ship until 1929, and then by ''Discovery II''. During this time she marked about 3,000 whales and completed biological, hydrographical and oceanographic studies. She also took part in the 2nd Wilkins- Hearst Antarctic Expedition in 1929-1930, launching a Lockheed Vega floatplane for flights over Antarctica. Laid up in St Katharine Docks in 1938, she was the requisitioned by the Admiralty in October 1939 and converted into a minesweeper. Commissioned as HMS ''William Scoresby'' (J122) in June 1940 she was stationed in the Falkland Islands. In ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chief Officer
A chief mate (C/M) or chief officer, usually also synonymous with the first mate or first officer, is a licensed mariner and head of the deck department of a merchant ship. The chief mate is customarily a watchstander and is in charge of the ship's cargo and deck crew. The actual title used will vary by ship's employment, by type of ship, by nationality, and by trade: for instance, ''chief mate'' is not usually used in the Commonwealth, although ''chief officer'' and ''first mate'' are; on passenger ships, the first officer may be a separate position from that of the chief officer that is junior to the latter. The chief mate answers to the captain for the safety and security of the ship. Responsibilities include the crew's welfare and training in areas such as safety, firefighting, search and rescue. Senior on board Operations Manager The Chief Mate, who is the second in command of the vessel, is often equated, in corporate terms, to a senior manager for the operations on boar ...
