Extracting Metal from the Sea â€" the Environmentally Friendly Way
A novel method that uses bacteria to mine valuable minerals from the ocean has been developed. Nodules collected from the Indian Ocean seabed can be treated to extract scarce land-based minerals in an environmentally sound way, says research published in the Journal of Chemical Technology and... view more (2004-04-02)

Global warming doubles rate of ocean rise
Global ocean levels are rising twice as fast today as they were 150 years ago, and human-induced warming appears to be the culprit.   view more (2005-11-28)

Study: 2004 tsunami was not first of large scale, awareness may improve future tsunami estimates
The deadly Indian Ocean tsunami of 2004, which claimed more than 200,000 lives, was not the first of its size to hit the region, according to new research by an international research team led by Dr. Karin Monecke, a former post-doctoral geologist at Kent State University.   view more (2008-10-31)

Fishing benefits from marine reserves
The creation of marine reserves in which fishing is banned can benefit fisheries in adjacent areas, according to Dr Callum Roberts of the Environment Department at the University of York.   view more (2001-11-30)

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976]... view more (2007-09-20)

Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair.   view more (2008-01-04)

Ocean floor geysers warm flowing sea water
An international team of earth scientists report movement of warmed sea water through the flat, Pacific Ocean floor off Costa Rica. The movement is greater than that off midocean volcanic ridges. The finding suggests possible marine life in a part of the ocean once considered barren.   view more (2008-09-23)

British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored... view more (2003-07-29)

Marine life stirs ocean enough to affect climate, says FSU study
Oceanographers worldwide pay close attention to phytoplankton and with good reason. The microscopic plants that form the vast foundation of the marine food chain generate a staggering amount of power.   view more (2006-10-16)

Industrial contaminants spread by seabirds in High Arctic, new Canadian study shows
Seabirds are the surprising culprits in delivering pollutants - through their guano - to seemingly pristine northern ecosystems, a new Canadian study shows.   view more (2005-07-15)

Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process.   view more (2006-02-07)

Southern ocean carbon sink weakened
Scientists have observed the first evidence that the Southern Ocean's ability to absorb the major greenhouse gas, carbon dioxide, has weakened by about 15 per cent per decade since 1981.   view more (2007-05-21)

Sunlight has more powerful influence on ocean circulation and climate than North American ice sheets
A study reported in today's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods.   view more (2008-11-07)

Volcanoes helped slow ocean warming trend, researchers find
Ocean temperatures might have risen even higher during the last century if it weren't for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity.   view more (2006-02-10)

Is it safe to go shopping?
Surveillance systems and devices that deactivate magnetic security tags at checkouts must limit the strength of their magnetic fields for safety reasons, according to research published today in the Institute of Physics journal Physics in Medicine and Biology. Researchers from the University of... view more (2001-10-03)

Ancient Deep Sea Coral Reefs Off Southeastern U.S. Serve as Underwater "Islands" in the Gulf Stream, Home to Many New Species of Animals
Largely unexplored deep-sea coral reefs, some perhaps hundreds of thousands of years old, off the coast of the southeastern U.S. are not only larger than expected but also home to commercially valuable fish populations and many newly discovered and unusual species.   view more (2008-05-19)

New laboratory to study the oceans and air
Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate. Examples include ocean... view more (2003-11-21)

Satellites capture first-ever gravity map of tides under Antarctic ice
Ohio State University scientists have used minute fluctuations in gravity to produce the best map yet of ocean tides that flow beneath two large Antarctic ice shelves.   view more (2005-12-05)

The critical importance of mangroves to ocean life
Mangroves, the backbone of the tropical ocean coastlines, are far more important to the global ocean's biosphere than previously thought.   view more (2006-02-28)

FLUCTUATIONS IN BIOLOGICAL PRODUCTION IN THE EQUATORIAL PACIFIC UNDERTHE EFFECT OF EL NINO
A region of the western equatorial Pacific, the Pacific warm pool, has exceptionally warm surface waters (an average 28.5°C) which have low salinity and are oligotrophic (nutrient-poor). At the Equator the Eastern edge of this pool comes into contact with cooler water (24°C on average)... view more (1999-05-11)

Prenatal Exposure To Mercury In Fish Not Associated With Impaired Neurodevelopment (p 1667, 1686)
Authors of a longitudinal study investigating a possible link between prenatal mercury exposure from ocean fish and impaired neurodevelopment in children report their latest findings in this week's issue of THE LANCET. The results confirm earlier findings that prenatal exposure to mercury in the... view more (2003-05-14)

Climate History Rewritten: Arctic Ice an Early Arrival
For the first time, scientists have pulled up prehistoric geologic records from the frigid vault of the Arctic Ocean. One of the findings, evidence of glacial Arctic ice from 45 million years ago, recasts a critical chapter of global climate history.   view more (2006-06-01)

Scientists discover new ocean current
Scientists at Georgia Tech have discovered a new climate pattern, the North Pacific Gyre Oscillation. This pattern explains, for the first time, changes in the water important in helping commercial fishermen understand fluctuations in the fish stock. They're also finding that as the Earth is... view more (2008-05-01)

Stanford researchers say living corals thousands of years old hold clues to past climate changes
Using radiocarbon dating and samples of deep-sea corals snipped from the floor of the Pacific Ocean by a submersible, researchers from Stanford and Lawrence Livermore National Laboratory have discovered that deep-sea corals growing off Hawaii are much older than previously thought-some as old as... view more (2008-02-15)

Ocean temperatures and sea level increases 50 percent higher than previously estimated
New research suggests that ocean temperature and associated sea level increases between 1961 and 2003 were 50 percent larger than estimated in the 2007 Intergovernmental Panel on Climate Change report.    view more (2008-06-19)
