Tara Expedition
The ''Tara'' expedition is an oceanic research expedition. The boat ''Tara'' is a 36-metre aluminum-hulled schooner, formerly named "Antarctica" then "Seamaster". Designed by the naval architects Olivier Petit and Luc Bouvet, built in France on the initiative of Jean-Louis Étienne, medical explorer, in 1989 the schooner Antarctica was used from 1991 to 1996 by Jean-Louis Étienne for scientific expeditions in Antarctica, at the Erebus volcano and then wintering at Spitzberg. Under its former name, it was owned by Peter Blake, who was shot and killed in 2001 by pirates while sailing ''Seamaster'' on the Amazon River. Following Blake's death, the yacht was bought by Etienne Bourgois, renamed Tara and dedicated to environmental expeditions. Expeditions The polar schooner ''Tara'' set out to drift in the ice for approximately two years from its first departure, late in August 2006. The expedition met with interest in the oceanography community, especially in the context of the Inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

Arctic Expeditions
The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. Definition and etymology The word Arctic comes from the Greek word (''arkti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schooners
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for priv ...

Drifting Ice Station
A drifting ice station is a temporary or semi-permanent facility built on an ice floe. During the Cold War the Soviet Union and the United States maintained a number of stations in the Arctic Ocean on floes such as Fletcher's Ice Island for research and espionage, the latter of which were often little more than quickly constructed shacks. Extracting personnel from these stations proved difficult and in the case of the United States, employed early versions of the Fulton surface-to-air recovery system. Overview Soviet and Russian staffed drifting ice stations are research stations built on the ice of the high latitudes of the Arctic Ocean. They are important contributors to exploration of the Arctic. The stations are named North Pole (NP; russian: Северный полюс, translit=Severny polyus, ), followed by an ordinal number: North Pole-1, etc. NP drift stations carry out the program of complex year-round research in the fields of oceanology, ice studies, meteorology, ae ...

Georgy Sedov
Georgy Yakovlevich Sedov (russian: Гео́ргий Я́ковлевич Седо́в; – ) was a Russian Arctic explorer. Born in the village of Krivaya Kosa of Taganrog district (now Novoazovskyi Raion, Donetsk Oblast) in a fisherman's family. In 1898, Sedov finished navigation courses in Rostov-on-Don and acquired the rank of long voyage navigator. In 1901, he took an external degree at Naval College, passed all the exams and was promoted to the rank of lieutenant. In 1902–1903, Sedov participated in a hydrographic expedition in the Arctic Ocean. During the Russo-Japanese War he was in charge of a torpedo boat (1905). In 1909, he led the expedition that would later describe the mouth of the Kolyma river. A year later Sedov explored the Krestovaya Bay on Novaya Zemlya. In 1912, he suggested a sleigh expedition for reaching the North Pole. The Tsarist government refused to finance this project, and the expedition was organized with the help from independent sources.

Fram (ship)
''Fram'' ("Forward") is a ship that was used in expeditions of the Arctic and Antarctic regions by the Norwegian explorers Fridtjof Nansen, Otto Sverdrup, Oscar Wisting, and Roald Amundsen between 1893 and 1912. It was designed and built by the Scottish-Norwegian shipwright Colin Archer for Fridtjof Nansen's 1893 Arctic expedition in which the plan was to freeze ''Fram'' into the Arctic ice sheet and float with it over the North Pole. ''Fram'' is preserved as a museum ship at the Fram Museum in Oslo, Norway. Construction Nansen's ambition was to explore the Arctic farther north than anyone else. To do that, he would have to deal with a problem that many sailing on the polar ocean had encountered before him: the freezing ice could crush a ship. Nansen's idea was to build a ship that could survive the pressure, not by pure strength, but because it would be of a shape designed to let the ice push the ship up, so it would "float" on top of the ice. ''Fram'' is a three-masted sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Pollution
Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. Plastics are inexpensive and durable, making them very adaptable for different uses; as a result, manufacturers choose to use plastic over other materials. However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade. Together, these two factors allow large volumes of plastic to enter the environment as mismanaged waste and for it to persist in the ecosystem. Plastic pollution can afflict land, waterways and oceans. It is estimated that 1.1 to 8.8 million tonnes of plastic waste enters the ocean from coastal communities each year. It is estimated that there is a stock of 86 million tons of plastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
