Scientists Confirm Historic Massive Flood in Climate Change
Scientists from NASA and Columbia University, New York, have used computer modeling to successfully reproduce an abrupt climate change that took place 8,200 years ago. At that time, the beginning of the current warm period, climate changes were caused by a massive flood of freshwater into the North Atlantic Ocean. view more (2006-03-01)
1,000 tags reveal mysteries of giant bluefin tuna
A giant Atlantic bluefin tuna weighing more than half a ton had the honor of being fitted with the 1000th electronic tracking tag placed on this threatened species when it was caught and released on Monday (October 20) in the Gulf of St. Lawrence off Port Hood, Nova Scotia. view more (2008-10-30)
Equatorial Atlantic Ocean Currents:Tracer Distribution Gives The Picture
The ocean has an immense capacity for storing heat. It therefore plays a major regulatory role in the Earth's heat-exchange mechanisms and climatic processes. From the global viewpoint, oceanic circulation involves the transport of water masses between the two hemispheres. In the Atlantic basin, a flux of cold water (at an average 4°C), the... view more...

Hurricanes are getting stronger, study says
The number of Category 4 and 5 hurricanes worldwide has nearly doubled over the past 35 years, even though the total number of hurricanes has dropped since the 1990s. view more (2005-09-16)
Continued warming of the Arctic Ocean
Several days ago, the 'Maria S Merian' returned from her second Arctic expedition with data confirming trends of Arctic warming. view more (2006-10-05)
Mistaken identity? When a white marlin may not always be a white marlin
For years, anglers thinking they were catching the prized white marlin may have caught something quite different, raising concerns about the true remaining numbers of the threatened species, according to an article in the most recent issue of the scientific journal Bulletin of Marine Science. view more (2007-02-26)
MINOS detector ready to take first data
Today, (August 14th), sees the start of data collection on the Main Injector Neutrino Oscillation Search (MINOS) detector, situated in the Soudan iron mine, Minnesota, USA. UK particle physicists, working within an international collaboration, will use the MINOS detector to investigate the phenomenon of neutrino mass - a puzzle that goes to the... view more...

Geophysical Research Letters European Highlights - 1 August 2001
Highlights 4. Deep water has many sources Hellmer and Beckmann ["The Southern Ocean: A Ventilation Contributor with Multiple Sources"] use a coupled ocean/ice-shelf model to determine the location and rate of Antarctic Bottom Water (AABW) formation. Their results suggest that the Atlantic and Indian-Pacific are equal contributors but produce... view more... (2001-07-16)
Has SOHO ended a 30-year quest for solar ripples?
The ESA-NASA Solar and Heliospheric Observatory (SOHO) may have glimpsed long-sought oscillations on the Sun's surface. The data will reveal details about the very core of our central star and it contains clues as to how the Sun formed, 4.6 billion years ago. view more (2007-05-04)
Scientists Conduct Shark Survey off U.S. East Coast
Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems. view more (2009-08-14)
Geologists: Opening of passage may be tied to Antarctic cooling
Ancient fish teeth are yielding clues about when Antarctica became the icy continent it is today, highlighting how ocean currents affect climate change. view more (2006-04-21)
Northwest Atlantic Ocean ecosystems experiencing large climate-related changes
Ecosystems along the continental shelf waters of the Northwest Atlantic Ocean—from the Labrador Sea south of Greenland all the way to North Carolina—are experiencing large, rapid changes, report oceanographers funded by the National Science Foundation (NSF) in the Feb. 23, 2007, issue of the journal Science. view more (2007-02-26)
1 of deep ocean's most turbulent areas has big impact on climate
More than a mile beneath the Atlantic's surface, roughly halfway between New York and Portugal, seawater rushing through the narrow gullies of an underwater mountain range much as winds gust between a city's tall buildings is generating one of the most turbulent areas ever observed in the deep ocean. view more (2007-08-10)
Short-circuit found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. view more (2007-05-11)
Marine deserts could give clues to understanding climate change
Remote 'marine deserts' in the Atlantic Ocean could provide scientists with valuable clues to understanding climate change. A research team led by the Plymouth Marine Laboratory will shortly set sail from the Falkland Islands, for the start of an expedition to study the interaction between tiny floating marine organisms (plankton) and the... view more...

A step nearer to understanding superconductivity
Transporting energy without any loss, travelling in magnetically levitated trains, carrying out medical imaging (MRI) with small-scale equipment: all these things could come true if we had superconducting materials that worked at room temperature. view more (2007-06-07)
Coralline algae in the Mediterranean lost their tropical element between 5 and 7 million years ago
An international team of researchers has studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. view more (2009-07-07)
Mama whales teach babies where to eat
University of Utah biologists discovered that young "right whales" learn from their mothers where to eat, raising concern about their ability to find new places to feed if Earth's changing climate disrupts their traditional dining areas. view more (2009-02-09)
Isotope analysis reveals foraging area dichotomy for Atlantic leatherback turtles
The beaches of French Guiana constitute a major reproduction site for leatherback turtles. This sea turtle, although a protected species, is threatened by human activity: it ingests plastics, get accidentally caught in fishing nets, sees its egg-laying sites destroyed and its adults hunted illegally for their meat and their eggs. view more (2008-03-26)
Signals from the Atlantic Salmon Highway
For years scientists have struggled to understand the decline and slow recovery of Atlantic salmon, a once abundant and highly prized game and food fish native to New England rivers. Biologists agree that poor marine survival is affecting salmon in the U.S. and Canada, but specific causes are difficult to determine in the ocean. Small acoustic... view more... (2008-08-19)
