Ocean Water Vertically Mixes As It Rushes Over Undersea Mountains
2013-09-19 07:58:02

April Flowers for redOrbit.com - Your Universe Online In the ocean near Antarctica, an international research team has solved the mystery of how deep and mid-depth ocean waters are mixed. The study, published in the journal Nature, reveals that sea water mixes dramatically as it rushes over undersea mountains in Drake Passage - the channel between the southern tip of South America and the Antarctic continent. This mixing of oceanic water layers is vital in the regulation of the Earth's...

Climate Impacts Of Polar Low Arctic Hurricanes
2012-12-17 05:32:40

redOrbit Staff & Wire Reports - Your Universe Online The intense, small scale storms known as polar lows could have a tremendous impact on oceanic water circulation and climate predictions, a team of researchers from the US and UK have discovered. According to scientists from the University of East Anglia (UEA) and the University of Massachusetts at Amherst, the storms, which are also known as Arctic hurricanes, contain areas of extremely low barometric pressure and can produce...

What Triggered Earth's Last Big Freeze
2012-11-06 09:53:08

April Flowers for redOrbit.com - Your Universe Online Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate. This debate concerning the melt, which ushered in the last major cold episode about 12,900 years ago, has been raging for about 30 years. A research team from the University of...

A new record of past temperature change in the tropical Atlantic Ocean's subsurface provides clues as to why the Earth's climate is so sensitive to ocean circulation patterns, according to climate scientists at Texas A&M University. Geological oceanographer Matthew Schmidt and two of his graduate students teamed up with Ping Chang, a physical oceanographer and climate modeler, to help uncover an important climate connection between the tropics and the high latitude North Atlantic....

Continuing Deep Ocean Change In The Southern Ocean

New research by teams of Australian and US scientists has found there has been a massive reduction in the amount of Antarctic Bottom Water found off the coast of Antarctica. Comparing detailed measurements taken during the Australian Antarctic program's 2012 Southern Ocean marine science voyage to historical data dating back to 1970, scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean...

Current called North Icelandic Jet contributes to key component of ocean circulation If you'd like to cool off fast in hot summer weather, take a dip in a newly discovered ocean current called the North Icelandic Jet (NIJ). You'd need to be far, far below the sea's surface near Iceland, however, to reach it. Scientists have confirmed the presence of the NIJ, a deep-ocean circulation system off Iceland. It could significantly influence the ocean's response to climate change. The...

Investigations of changes in Weddell Sea habitat The research vessel Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association will arrive back at its homeport of Bremerhaven after a seven-month expedition on Friday, 20 May. Nearly 200 researchers from institutes in 15 countries took part in the expedition. The oceanographers on board conducted measurements showing that warming of the water in the deep Weddell Sea continues further. The observations...

Increased Agulhas "leakage" significant player in global climate variability The Agulhas Current which runs along the east coast of Africa may not be as well known as its counterpart in the Atlantic, the Gulf Stream. But now researchers are taking a closer look at this current and its "leakage" from the Indian Ocean into the Atlantic Ocean--and what that may mean for climate change In results of a study published in this week's issue of the journal Nature, a team of scientists led by...

Oceanographers are monitoring a vast expanse of fresh water in the Arctic Ocean that could spill into the Atlantic, something that could result in unpredictable changes in the ocean currents that give Western Europe its moderate climate. The scientists said Tuesday that the unusual accumulation of fresh water resulted from the Siberian and Canadian rivers dumping more water into the Arctic, and from melting sea ice. "The volume of water discharged into the Arctic Ocean, largely from Canadian...

Scientists and explorers will shortly set off on an expedition aiming to discover how Arctic sea ice melts. This year's Catlin Arctic Survey is focused on the thin layer of water immediately under the floating ice. Arctic ice is melting faster in the summer than many computer models have predicted. Survey data could improve forecasts of the region's future, and show how likely it is that the flow of warm water in the North Atlantic will switch off. This would bring colder weather to the...
