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] |
Technology
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Grove in 1838. The first commercial use of fuel cells came more than a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for satellites and space capsules. Since then, fuel cells have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Yacht Racing
Yacht racing is a Sailing (sport), sailing sport involving sailing yachts and larger sailboats, as distinguished from dinghy racing, which involves open boats. It is composed of multiple yachts, in direct competition, racing around a course marked by buoys or other fixed navigational devices or racing longer distances across open water from point-to-point. It can involve a series of races with buoy racing or multiple legs when point-to-point racing. History Yachting, that is, recreational boating, is very old, as exemplified in the ancient poem Catullus 4: The yacht you see there, friends, says that she's been The fastest piece of timber ever seen; She swears that once she could have overhauled All rival boats, whether the challenge called For racing under canvas or with oars. (trans. James Michie) "Yacht" is referred to as deriving from either Norwegian ("jagt"), Middle Low German ("jaght") or from the Dutch word jacht, which means "a swift light vessel of war, commerce or p ...

Daedalus (yacht)
''Daedalus'' is a maxi- catamaran, that participated in numerous open-ocean races under various owners and names. History Originally named ''Formule Tag'', this maxi-catamaran was built by Canadair in Québec, Canada in 1983, under the supervision of Canadian skipper Mike Birch and British designer Nigel Irens. The yacht was built to compete in the inaugural Transat Québec-Saint-Malo—a trans- North Atlantic sailing race celebrating Jacques Cartier's 1534 voyage from Saint-Malo, France, to present day Québec City. It was the largest sailing catamaran of its time, with a length of 85 feet, and participated in a number of races. In 1984 Birch and crew sailed her to a new record for a Day's run, sailing 512 nautical miles in 24 hours. In 1993, ''Formule Tag'' was purchased by Robin Knox-Johnston and future two-time America's Cup winner Peter Blake. The two skippers renamed her ''ENZA New Zealand'' (ENZA an acronym for Eat New Zealand Apples). The two launched a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multihull
A multihull is a boat or ship with more than one hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans (with two hulls), and trimarans (with three hulls). There are other types, with four or more hulls, but such examples are very rare and tend to be specialised for particular functions. Sailing multihulls Counter-intuitively, it is unhelpful to think of the design progression to be "1-2-3", namely monohull - catamaran - trimaran; rather, it is "1-3-2". A sailing trimaran is, in effect, a modified monohull with lightweight outrigger hulls (or "amas") for stability instead of a heavy deep keel; so it follows that a sailing trimaran will be lighter and faster than a sailing monohull. A sailing trimaran will have a centre hull that may comprise up to 90% of total hull volume, and 95% of total deadweight. A sailing trimaran at rest will have both amas out of the water and, when heeled, will only ever have one of the amas immersed. A ...
