Global warming could halt ocean circulation, with harmful results
Absent any climate policy, scientists have found a 70 percent chance of shutting down the thermohaline circulation in the North Atlantic Ocean over the next 200 years, with a 45 percent probability of this occurring in this century.   view more (2005-12-08)

Lionfish decimating tropical fish populations, threaten coral reefs
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.   view more (2008-07-21)

New deep-sea hydrothermal vents, life form discovered
A new "black smoker"—an undersea mineral chimney emitting hot springs of iron-darkened water—has been discovered at 8,500-foot depths by an expedition funded by the National Science Foundation (NSF) to explore the Pacific Ocean floor off Costa Rica.   view more (2007-04-20)

Independent Panel Recommends Strong, Clear Guidelines for Development of Marine Aquaculture in the United States
Congress should enact legislation to ensure that strong environmental standards are in place to regulate the siting and conduct of offshore marine aquaculture, according to an independent panel of leaders from scientific, policymaking, business, and conservation institutions.   view more (2007-01-09)

B12 Is Also an Essential Vitamin for Marine Life
B12 - an essential vitamin for land-dwelling animals, including humans - also turns out to be an essential ingredient for growing marine plants that are critical to the ocean food web and Earth's climate, scientists have found.   view more (2007-05-21)

Overfishing puts Southern California kelp forest ecosystems at risk, report scientists
Kelp forest ecosystems that span the West Coast -- from Alaska to Mexico's Baja Peninsula -- are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore.   view more (2006-05-26)

Ocean Cores May Give Clues On Climate Change
Core samples taken from far below the ocean floor are helping a University of Edinburgh geologist to form a picture of dramatic climate changes which took place 30 to 40 million years ago. Dr Bridget Wade is part of an international team of scientists studying climate shifts between the Eocene... view more (2002-05-03)

Iron in Northwest rivers fuels phytoplankton, fish populations
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.   view more (2007-03-01)

Geologists Find New Origins of Appalachian Mountains
Geologists have developed a new theory to explain how and when the Appalachian Mountain range was created. Their research redraws the map of the planet from 420 million years ago.   view more (2006-11-17)

Snowball Antarctica - early Drake passage opening led to global change
New results shed light on how Antarctica became the icy, barren continent that we know today.   view more (2005-08-31)

Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage.   view more (2007-11-07)

Complex ocean behavior studied with 'artificial upwelling'
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.   view more (2008-09-03)

Durham geologists land funding for vital seabed survey equipment
Durham University researchers in Geological Sciences are set to focus their deep-sea surveying skills on shallower waters to produce new information that will help shipping, minerals and offshore oil industries. They are partners in a five-university project that has secured key funding in the... view more (2000-12-19)

ESA keeps vigil on the Antarctic ice pack
An unusually heavy Antarctic sea-ice pack has kept polar supply ship Magdalena Oldendorff trapped for more than a month. A multinational rescue mission already evacuated passengers and non-essential crew from the vessel, caught in ice while returning from the Russian base of Novolazarevskaya on... view more (2002-07-19)

Climate Prediction:
The symposium was held in Tokyo at the Tokyo International Forum on March 5th. It was opened by Mr. Uchida, Director General of NASDA (National Space Development Agency, Japan) and by A. Ghazi, Head of Biodiversity and Global Change Unit DG XII, European Commission. The discussions at the Hakone... view more (1999-03-22)

Nutrient-poor oceans generate their food "hot spots"
The oceans have their desert zones, in other words areas poor in nutrients and unfavourable for phytoplankton to develop. Half of the southern Pacific thus consists of great expanses of warm water with an average temperature of 28 °C (a greater surface area than Europe), which receives no input... view more (2004-01-13)

Fire under the ice
An international team of researchers was able to provide evidence of explosive volcanism in the deeps of the ice-covered Arctic Ocean for the first time.   view more (2008-06-26)

Extinction by asteroid a rarity
In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong.   view more (2008-10-07)

First map of threats to marine ecosystems shows all the world's oceans are affected
As vast and far-reaching as the world's oceans are, every square kilometer is affected by human activities, according to a study in the journal Science by researchers at the University of North Carolina at Chapel Hill and others.   view more (2008-02-15)

Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have... view more (2008-09-23)

Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean.   view more (2006-10-05)

Research shows loggerhead sea turtles threatened by small-scale fishing operations
Washington, DC. Ocean Conservancy Scientist, Wallace J. Nichols and University of California-Santa Cruz researcher Hoyt Peckham found surprising results in a recent peer-reviewed loggerhead sea turtle study that Nichols and Peckham conducted over the course of 10 years. The full study will be... view more (2007-10-17)

Asphalt flows from deep-sea volcanoes
New kind of volcano discovered in the Gulf of Mexico Underwater volcanoes that spew asphalt instead of lava: they were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Prof. Gerhard Bohrmann of the DFG Research Center Ocean Margins. On these volcanoes the... view more (2004-05-17)
