A team of scientists is studying the complex ocean upwelling process by mimicking nature "“ pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production. The researchers are harnessing the power of the ocean to conduct their experiments, using the up-and-down motion of waves to pump deep water to the surface. Their next step is to create a pump...

According to Oman News: The Ministry of Fisheries said that the offensive smell at the Sultanate coasts from al Batinah region to Muscat governorate is mainly due to a natural phenomenon called 'upwelling'. The offensive smell will dissolve soon, the Ministry added.Eng. Abdul Aziz bin Said al Marzouqi, Acting Director of the Marine and Fisheries Sciences Center said, 'as per the latest satellite images, as well as, the pictures obtained by the remote station of the Fisheries and Marine...

By Jacqueline L. Urgo, The Philadelphia Inquirer Jul. 13--ATLANTIC CITY -- The temperatures may be steamy outside, but, baby, it's cold in the water. Just ask Melinda Castile, down the Shore for a week from Brooklyn, N.Y., and determined to go in the ocean no matter what the temperature. She bought a wetsuit. "I know it looks weird, but too bad. The water's freezing," said Castile, 28, as she emerged from the chilly surf near the Brighton Avenue beach. Then there was Lacy Julius, 3,...

An international team of scientists surveying the waters of the continental shelf off the West Coast of North America has discovered for the first time high levels of acidified ocean water within 20 miles of the shoreline, raising concern for marine ecosystems from Canada to Mexico.Researchers aboard the Wecoma, an Oregon State University research vessel, also discovered that this corrosive, acidified water that is being "upwelled" seasonally from the deeper ocean is probably 50 years old,...

Is the Dust-Storm Theory Overblown? Most oceanographers have assumed that, in the areas of the world's oceans known as High Nutrient, Low Chlorophyll (HNLC) regions, the iron needed to fertilize infrequent plankton blooms comes almost entirely from wind-blown dust. Phoebe Lam and James Bishop of the Earth Sciences Division at the Department of Energy's Lawrence Berkeley National Laboratory have now shown that in the North Pacific, at least, it just isn't so. In a forthcoming issue of...

Climate mechanism could explain 1940s crash that led to demise of Cannery Row The mid-20th century crash of the sardine fishery off California for decades has vexed marine ecologists searching for the root causes of large fluctuations in the sardine population. Before its collapse, the fishery was one of the world's most productive and formed the setting of John Steinbeck's "Cannery Row" in Monterey, Calif. Scientists at Scripps Institution of Oceanography at UC San Diego have now shed light...

CORVALLIS, Ore. -- A new study suggests that the iron-rich winter runoff from Pacific Northwest streams and rivers, combined with the wide continental shelf, form a potent mechanism for fertilizing the nearshore Pacific Ocean, leading to robust phytoplankton production and fisheries. The study, by three Oregon State University oceanographers, was just published by the American Geophysical Union in its journal, Geophysical Research Letters. West coast scientists have observed that ocean...

DURHAM, N.C. -- Duke University oceanographers have developed an explanation for why a vast North Atlantic circulation zone can have a large variability in nutrient supplies needed to sustain ocean plants and, by extension, support the food web of marine life. The circulating zone in the North Atlantic Ocean, known as a "subtropical gyre," swirls in a clockwise direction between the Gulf Stream -- the warm current that bisects the Atlantic between the southern U.S. and northern Europe -- and...

SAN FRANCISCO -- The northerly winds that sustain the Pacific Coast's marine ecosystems have returned, but their arrival came too late for fish and birds that couldn't survive the unseasonably warm waters. Coastal ecosystems rely on winds blowing south to push warmer surface waters away from shore and bring up colder water from the ocean bottom. That upwelling of nutrient-rich water feeds massive blooms of plankton - the tiny plant-like organisms that form the basis of the marine food web....

NASA -- Who would have thought that melting snow cover in the Himalayan Mountains could alter the ocean food chain over a thousand miles away? Well, that's just what's happening, according to a NASA-funded study appearing in this week's Science magazine. The study finds a decline in winter and spring snow cover over Southwest Asia and the Himalayan mountain range is creating the right conditions for more widespread blooms of ocean plants in the Arabian Sea. The decrease in snow cover has...

Ocean Current Impacts On Weather
2012-07-30 13:25:48

The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific are transported west to east and start to replace these colder waters. The Peru current is...

Coastal Upwelling- this is defined as the moving of water from the deeper oceans upwards to the surface of the ocean very commonly found along our cold ocean currents, which are found along the West Coast of the United States and off the Peru coast. Coastal Sinking- this is defined as the warm waters moving in from the east and hitting the coastline and slowly filtering down towards the deeper ocean waters very slowly. This feature is common in our warm ocean currents such as the United...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
