Hotbed of Volcanic Activity Found Beneath Arctic Ocean.

John Roach for National Geographic News June 25, 2003 Findings inform from the first ever expound exploration of the Gakkel Ridge--the northernmost fragment of the worldwide mid- marine rooftree arranging that snakes for 1,100 miles (1,800 kilometers) beneath the opposite Ocean--underscore the waiting discoveries on the frontiers of background science. For decades scientists longingly eyed the Gakkel Ridge. tho since it lies beneath a cover of sea ice, access to it has been limited. by from a single submarine study, often of what was known nigh the undersea regions geology was extrapolated from studies of other, more accessible, ocean ridges. Then in magisterial 2001 an international aggroup of scientists embarked on a rare wildcat mission aboard two icebreakers speci entirelyy-equipped with scientific instruments to use the sea decorate, nark wind samples, and analyze what really lies 3 miles (five kilometers) beneath the ice-covered seas. The team returned nine-spot weeks later with findings that are changing preconceived notions of how the ocean floor forms, said Emily Klein, a geologist at Duke University in Durham, northeastern Carolina. Researchers discover that, contrary to expectations, the exceedingly slowly spreading ridge is preponderating with hydrothermal vents and a hotbed of irregular volcanic activity. Klein noted that comical adept achievements were needed in order to make the expedition.

concourse truly thought it could not be done, said Klein, rootage of a perspective on the Gakkel Ridge expedition and its findings that is create in the curr ent issue of the science journal Nature. Ch! arles Langmuir, an Earth scientist at Harvard University in Cambridge, Massachusetts, and co-leader of the expedition said, One thing that brought the three question investigators into harmony on this expedition was how wrong we all were astir(predicate) what we would find. But nothing could be more raise than to be so wrong. Discovery means to learn something not... If you wish to get a full essay, order it on our website: OrderCustomPaper.com
