Latest Upwelling Stories
A team of scientists is studying the complex ocean upwelling process by mimicking nature â€“ 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.
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.
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.
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.
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.
The scientists say their findings may explain the sardine and anchovy booms and busts off California's coast and could explain similar population cycles elsewhere around the world.
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.
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 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.
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 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...
