Moving leftward, he helped form the Red Circle, a Marxist tendency within the Waffle. When the Waffle was forced out of the NDP in 1972, Flexer and the Red Circle split with the Waffle, opposing its decision to leave the NDP, and tried to continue Marxist activities within the NDP.

paragraph_text: Eltanin Bay is a bay in Antarctica about wide in the southern Bellingshausen Sea that indents the coast of Ellsworth Land west of the Wirth Peninsula. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–66, and was named by the Advisory Committee on Antarctic Names for the United States Antarctic Research Program oceanographic research ship "Eltanin" which made numerous research cruises in the South Pacific Ocean.

paragraph_text: The uninhabited Marvin Islands are located in the Arctic Ocean across the mouth of Disraeli Fiord, in northern Ellesmere Island within the Quttinirpaaq National Park. Ward Hunt Island lies to the northwest. The island group is a part of the Qikiqtaaluk Region Nunavut, Canada.

paragraph_text: The Queen Maud Mountains are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales. Despite the name, they are not located within Queen Maud Land.

paragraph_text: The Thing (also known as John Carpenter's The Thing) is a 1982 American science - fiction horror film directed by John Carpenter, written by Bill Lancaster, and starring Kurt Russell. The film's title refers to its primary antagonist: a parasitic extraterrestrial lifeform that assimilates other organisms and in turn imitates them. The Thing infiltrates an Antarctic research station, taking the appearance of the researchers that it absorbs, and paranoia develops within the group.

paragraph_text: Winter Quarters Bay is a small cove of McMurdo Sound, Antarctica, located due south of New Zealand at 77°50'S. The harbor is the southern-most port in the Southern Ocean and features a floating ice pier for summer cargo operations. The bay is approximately 250m wide and long, with a maximum depth of 33m. The name Winter Quarters Bay refers to Robert Falcon Scott's National Antarctic Discovery Expedition (1901–04) which wintered at the site for two seasons.

paragraph_text: Central Coast Regional District is a regional district in British Columbia, Canada. It has a total land area of 24,559.5 km² (9,482.5 sq mi). When it was created in 1968, it was known as the Ocean Falls Regional District, named for the then-largest town in the region, the company town of Ocean Falls, which has since become a ghost town. The district name was confirmed in 1974, but changed to Central Coast Regional District in 1976.

paragraph_text: The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of tubenoses (Procellariiformes) such as albatrosses circle the earth, flying over the southern oceans, while others such as Manx shearwaters migrate 14,000 km (8,700 mi) between their northern breeding grounds and the southern ocean. Shorter migrations are common, including altitudinal migrations on mountains such as the Andes and Himalayas.

paragraph_text: The Southern Ocean, geologically the youngest of the oceans, was formed when Antarctica and South America moved apart, opening the Drake Passage, roughly 30 million years ago. The separation of the continents allowed the formation of the Antarctic Circumpolar Current.

paragraph_text: HMCS "Chaleur" was a that served in the Royal Canadian Navy for three and a half months in 1954 before being sold to the French Navy to become "La Dieppoise". The ship was named for Chaleur Bay, located between Quebec and New Brunswick. Her name was given to her replacement, . As "La Dieppoise", the vessel served as a coastal patrol vessel in the France's Pacific Ocean territories. The ship was taken out of service in 1987.

paragraph_text: The Dos Rios AVA is an American Viticultural Area located in northern Mendocino County, California. The appellation is located near the confluence of the Eel River and the Middle Fork of the Eel River. The name of the appellation is Spanish for "two rivers". The location would have a warm climate if not for constant breezes from the Pacific Ocean. The soil in Dos Rios is more infertile than other regions in the county. Only one winery, Vin de Tevis, currently operates within the boundaries of the AVA.

paragraph_text: Cedar Beach is an unincorporated community within Berkeley Township, in Ocean County, New Jersey, United States. It is situated on Barnegat Bay and located east of U.S. Route 9.

paragraph_text: Elephant Island is an ice-covered mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. Its name was possibly given by early explorers sighting elephant seals on its shores. The island is situated north-northeast of the tip of the Antarctic Peninsula, west-southwest of South Georgia, south of the Falkland Islands, and southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the UK. Brazil has a shelter on the island, Goeldi, supporting the work of up to six researchers each during the summer and had another (Wiltgen), which was dismantled in the summer of 1997/98.

paragraph_text: The most pelagic species, mainly in the 'tubenose' order Procellariiformes, are great wanderers, and the albatrosses of the southern oceans may circle the globe as they ride the "roaring forties" outside the breeding season. The tubenoses spread widely over large areas of open ocean, but congregate when food becomes available. Many are also among the longest-distance migrants; sooty shearwaters Puffinus griseus nesting on the Falkland Islands migrate 14,000 km (8,700 mi) between the breeding colony and the North Atlantic Ocean off Norway. Some Manx shearwaters Puffinus puffinus do this same journey in reverse. As they are long-lived birds, they may cover enormous distances during their lives; one record-breaking Manx shearwater is calculated to have flown 8 million km (5 million miles) during its over-50 year lifespan.

paragraph_text: By way of his voyages in the 1770s, Captain James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian Oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), this situation has no scientific sense since it has different ecosystem and life from the three oceans mentioned before and is located on a southern portion of Earth, hence the name of an ocean. This remains the current official policy of the IHO, since a 2000 revision of its definitions including the Southern Ocean as the waters south of the 60th parallel has not yet been adopted. Others regard the seasonally - fluctuating Antarctic Convergence as the natural boundary.

paragraph_text: The word ``protoplasm ''comes from the Greek protos for first, and plasma for thing formed, and was originally used in religious contexts. It was used in 1839 by J.E. Purkinje for the material of the animal embryo. Later, in 1846 Hugo von Mohl redefined the term (also named as Primordialschlauch,`` primordial utricle'') to refer to the ``tough, slimy, granular, semi-fluid ''substance within plant cells, to distinguish this from the cell wall and the cell sap (Zellsaft) within the vacuole. Thomas Huxley (1869) later referred to it as the`` physical basis of life'' and considered that the property of life resulted from the distribution of molecules within this substance. The protoplasm became an ``epistemic thing ''. Its composition, however, was mysterious and there was much controversy over what sort of substance it was.

paragraph_text: Himalia Ridge is a ridge running east–west on the north side of the Ganymede Heights massif, north-east of Jupiter Glacier, in the east of Alexander Island, Antarctica. It was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey in 1960. The ridge was named by the UK Antarctic Place-Names Committee following British Antarctic Survey geological work, 1983–84, after Himalia, a satellite of the planet Jupiter, in association with Jupiter Glacier. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
