Southern Cross Expedition
The ''Southern Cross'' Expedition, otherwise known as the British Antarctic Expedition, 1898–1900, was the first British venture of the Heroic Age of Antarctic Exploration, and the forerunner of the more celebrated journeys of Robert Falcon Scott and Ernest Shackleton. The brainchild of the Anglo-Norwegian explorer Carsten Borchgrevink, it was the first expedition to over-winter on the Antarctic mainland, the first to visit the Great Ice Barrier—later known as the Ross Ice Shelf—since Sir James Clark Ross's groundbreaking expedition of 1839 to 1843, and the first to effect a landing on the Barrier's surface. It also pioneered the use of dogs and sledges in Antarctic travel. The expedition was privately financed by the British magazine publisher Sir George Newnes. Borchgrevink's party sailed in the , and spent the southern winter of 1899 at Cape Adare, the northwest extremity of the Ross Sea coastline. Here they carried out an extensive programme of scientific observations, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louis Bernacchi
Louis Charles Bernacchi (8 November 1876 – 24 April 1942) was an Australian physicist and astronomer best known for his role in several Antarctic expeditions. Early life Bernacchi was born in Belgium on 8 November 1876 to Italian parents in one of the communes of Brussels known as Schaerbeek. His father, Diego Bernacchi, established a vineyard on Maria Island in 1884. He was educated in Hobart, Tasmania, at the Hutchins School from May 1889 and finishing at the school around Easter 1891. He entered the Melbourne Observatory in 1895 where he spent about three years studying magnetism and meteorology. During this period he developed an interest in Antarctic exploration, expressed in letters to the press and by following the proceeding of Antarctic Exploration Committees. Polar exploration He joined Carstens Borchgrevink's Southern Cross expedition (1898–1900) which wintered at Cape Adare, Antarctica, joining the expedition in Christchurch, New Zealand after the previ ...

Alfred Harmsworth
Alfred Charles William Harmsworth, 1st Viscount Northcliffe (15 July 1865 – 14 August 1922), was a British newspaper and publishing magnate. As owner of the ''Daily Mail'' and the ''Daily Mirror'', he was an early developer of popular journalism, and he exercised vast influence over British popular opinion during the Edwardian era. Lord Beaverbrook said he was "the greatest figure who ever strode down Fleet Street." About the beginning of the 20th century there were increasing attempts to develop popular journalism intended for the working class and tending to emphasize sensational topics. Harmsworth was the main innovator. Northcliffe had a powerful role during the First World War, especially by criticizing the government regarding the Shell Crisis of 1915. He directed a mission to the new ally, the United States, during 1917, and was director of enemy propaganda during 1918. His Amalgamated Press employed writers such as Arthur Mee and John Hammerton, and its subsidiary, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir Clements Markham
Sir Clements Robert Markham (20 July 1830 – 30 January 1916) was an English geographer, explorer and writer. He was secretary of the Royal Geographical Society (RGS) between 1863 and 1888, and later served as the Society's president for a further 12 years. In the latter capacity he was mainly responsible for organising the British National Antarctic Expedition of 1901–1904, and for launching the polar career of Robert Falcon Scott. Markham began his career as a Royal Navy cadet and midshipman, during which time he went to the Arctic with in one of the many searches for Franklin's lost expedition. Later, Markham served as a geographer to the India Office, and was responsible for the collection of cinchona plants from their native Peruvian forests, and their transplantation in India. By this means, the Indian government acquired a home source from which quinine could be extracted. Markham also served as geographer to Sir Robert Napier's Abyssinian expeditionar ...

University Of Canterbury
The University of Canterbury ( mi, Te Whare Wānanga o Waitaha; postnominal abbreviation ''Cantuar.'' or ''Cant.'' for ''Cantuariensis'', the Latin name for Canterbury) is a public research university based in Christchurch, New Zealand. It was founded in 1873 as Canterbury College, the first constituent college of the University of New Zealand. It is New Zealand's second-oldest university, after the University of Otago, itself founded four years earlier in 1869. Its original campus was in the Christchurch Central City, but in 1961 it became an independent university and began moving out of its original neo-gothic buildings, which were re-purposed as the Christchurch Arts Centre. The move was completed on 1 May 1975 and the university now operates its main campus in the Christchurch suburb of Ilam. The university is well known for its Engineering and Science programmes, with its Civil Engineering programme ranked 9th in the world (Academic Ranking of World Universities, 2021). ...

Overwinter
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering. Hibernation and migration are the two major ways in which overwintering is accomplished. Animals may also go into a state of reduced physiological activity known as torpor. Overwintering occurs in several classes of lifeform. Insects In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the insect fr ...

Blubber
Blubber is a thick layer of vascularized adipose tissue under the skin of all cetaceans, pinnipeds, penguins, and sirenians. Description Lipid-rich, collagen fiber-laced blubber comprises the hypodermis and covers the whole body, except for parts of the appendages. It is strongly attached to the musculature and skeleton by highly organized, fan-shaped networks of tendons and ligaments, can comprise up to 50% of the body mass of some marine mammals during some points in their lives, and can range from thick in dolphins and smaller whales, to more than thick in some bigger whales, such as right and bowhead whales. However, this is not indicative of larger whales' ability to retain heat better, as the thickness of a whale's blubber does not significantly affect heat loss. More indicative of a whale's ability to retain heat is the water and lipid concentration in blubber, as water reduces heat-retaining capacities, and lipid increases them. Function Blubber is the primary fat st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonies ...

Possession Islands
The Possession Islands are a group of small islands and rocks extending over an area of about , lying in the western part of the Ross Sea, lying south-east of Cape McCormick and east of Cape Roget, in Victoria Land, Antarctica. The Possession Islands were named by Captain James Clark Ross, Royal Navy, in commemoration of the planting of the British flag here on January 12, 1841. Possession Island Possession Island is a rocky island nearly long. The northernmost and largest of the group, it is located at . Archer Peak is a mountain on the southernmost edge of the island. Important Bird Area A site comprising the whole island has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 111,000 breeding pairs of Adélie penguins, based on ground counts made from 1981 to 2012. A significant south polar skua colony is also present on the island. See also * Composite Antarctic Gazetteer * List of Antarctic and Subantarctic islands * L ...

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...
