Borradaile Island
Borradaile Island () is one of the Balleny Islands. It was the site of the first landing south of the Antarctic Circle, and features the "remarkable pinnacle" called ''Beale Pinnacle'', near Cape Beale on its south-eastern coast, and Cape Scoresby on its north-western coast. Exploration Borradaile Island was discovered in February 1839 by John Balleny, who named it for W. Borradaile, one of the merchants who united with Charles Enderby in sending out the expedition. The first landing on the island was by Captain Freeman of the cutter ''Sabrina'' on February 12, 1839, who landed briefly on a spit at the islands north-west corner. This was the first time a human set foot south of the Antarctic Circle. The island was not visited again until February 29, 1948, when a party of Australians, including Phillip Law and Stuart Campbell, landed at the same point from . Features Borradaile Island is about long and wide, lying southeastward of Young Island. Cape Scoresby () is a high bluff ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ...

Balleny Islands
The Balleny Islands () are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot. The group includes three main islands: Young, Buckle and Sturge, which lie in a line from northwest to southeast, and several smaller islets and rocks: *northeast of Young Island: Seal Rocks, Pillar *southeast of Young Island: Row Island, Borradaile Island (with Swan Base shelter hut) *south of Buckle Island: Scott Cone, Chinstrap Islet, Sabrina Islet (with Sabrina Refuge shelter hut), and the Monolith The islands are claimed by New Zealand as part of the Ross Dependency (see Territorial claims in Antarctica). Islands and rocks from north to south The islands' area totals and the highest point has been ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Antarctic Circle
The Antarctic Circle is the most southerly of the five major circles of latitude that mark maps of Earth. The region south of this circle is known as the Antarctic, and the zone immediately to the north is called the Southern Temperate Zone. South of the Antarctic Circle, the Sun is above the horizon for 24 continuous hours at least once per year (and therefore visible at midnight) and the centre of the Sun (ignoring refraction) is below the horizon for 24 continuous hours at least once per year (and therefore not visible at noon); this is also true within the equivalent polar circle in the Northern Hemisphere, the Arctic Circle. The position of the Antarctic Circle is not fixed and currently runs south of the Equator. This figure may be slightly inaccurate because it does not allow for the effects of astronomical nutation, which can be up to 10″. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, due ...

John Balleny
John Balleny (died 1857) was the English captain of the sealing schooner , who led an exploration cruise for the English whaling firm Samuel Enderby & Sons to the Antarctic in 1838–1839. During the expedition of 1838–1839, Balleny, sailing in company with Thomas Freeman and , sailed into the Southern Ocean along a corridor of longitude centering on the line of 175°E., south of New Zealand. Biography Balleny was born approximately 1770, and by 1798 was living in St George in the East, then the shipping quarter of London, and was part owner of a 569 ton ship, ''Blenheim''. He was recorded as ship's master for a few trading ships up until 1824, including the trading ship ''Lord Cathcart'' and the 269-ton brig ''Peace''. In 1824, he owned part of a whaling barque, ''Caledonia'', but was not longer registered as the master of any ship for the following year, possibly indicating his retirement.

Charles Enderby
Charles Enderby (1797–1876) was one of three sons of Samuel Enderby Junior (1756–1829). He was the grandson of Samuel Enderby (1717–1797), who founded the Samuel Enderby & Sons company in 1775. Samuel Enderby & Sons was one of the most prominent English sealing and whaling firms, active in both the Arctic and Southern Oceans. Charles and his two brothers, Henry and George, inherited Samuel Enderby & Sons when their father Samuel Junior died in 1829. They moved the company headquarters in 1830 from Paul's Wharf to Great St. Helens in London. Role of Samuel Enderby & Sons in exploration of Antarctica and the Southern Ocean Also in 1830, Charles became a founding member of the Royal Geographical Society (RGS). He served on the council of the RGS on several occasions between 1842 and 1847. Charles encouraged masters of Enderby vessels to report geographical discoveries and had notable successes with John Biscoe and John Balleny, who between them discovered Enderby Lan ...

Young Island
Young Island () is the northernmost and westernmost of the three main islands in the uninhabited Balleny Islands group located in the Southern Ocean. It lies northwest of Buckle Island, some north-northeast of Belousov Point on the Antarctic mainland. The island is roughly semi-oval in shape, with a long straight east coast and a curved west coast meeting at Cape Scoresby in the south and Cape Ellsworth in the north. The distance between these two capes is , and at its widest the island is across. The island is volcanic, with active fumaroles, and a height of . It is entirely covered with snow. An explosive Volcanic Explosivity Index, VEI-7 eruption occurred from Young Island 1,700,000 years ago. Several small islets lie in the channel separating Cape Scoresby and Buckle Island, the largest of which is Borradaile Island. Several sea stacks lie off the island's northern tip. These are known as the Seal Rocks. The island forms part of the Ross Dependency, claimed by New Zealand ...

RRS Discovery II
RRS ''Discovery II'' was a British Royal Research Ship which, during her operational lifetime of about 30 years, carried out considerable hydrographical and marine biological survey work in Antarctic waters and the Southern Ocean in the course of the Discovery Investigations research program. Built in Port Glasgow, launched in 1928 and completed in 1929, she was the first purpose-built oceanographic research vessel and was named after Robert Falcon Scott's 1901 ship, RRS ''Discovery''. Career The ship's maiden voyage took place from December 1929 to May 1931 and consisted of a hydrographic survey of the South Sandwich Islands. From October 1932 until May 1933 she operated in the Antarctic, calling at South Africa, Australia and New Zealand. Similar voyages took place from 1934 to 1939 during which she supplied the British Graham Land expedition. Her last voyage before the onset of war was from September 1937 to May 1939. In December 1935 and January 1936 the ship was invo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Running Survey
A running survey is a rough survey made by a vessel while coasting. Bearings to landmarks are taken at intervals as the vessel sails offshore, and are used to fix features on the coast and further inland. Intervening coastal detail is sketched in. The method was used by James Cook, and subsequently by navigators who sailed under—or were influenced by—him, including George Vancouver, William Bligh and Matthew Flinders Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to u .... References Navigation Surveying James Cook {{Hydrography-stub ...

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 earl ...
