Oceans turning to acid from rise in CO2
A report issued by the Royal Society in the U.K. sounds the alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine life in ways we can't anticipate," commented Dr. Ken Caldeira, co-author of the report and a newly appointed staff scientist at the... view more...

Coral reefs found growing in cold, deep ocean
Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 metres under the surface of the Atlantic. view more (2008-11-05)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
The dawn of deep ocean mining
We're on the brink of the era of deep ocean mining, says a global pioneer in the study of sea floor mineral deposits. view more (2006-02-21)
Rapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration
Scientists have found new evidence that the Bering Strait near Alaska flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years earlier than widely believed, closing off the land bridge thought to be the major route for human migration from Asia to the Americas. view more (2006-10-12)
Southampton gets ready for largest ever Unmanned Underwater Vehicle Showcase
Over 80 of the world's leading developers and manufacturers of unmanned underwater vehicles and sub-systems are gathering in Southampton next week (2-3 September), to take part in the largest ever Unmanned Underwater Vehicle Showcase (UUVS 98). view more (1998-08-28)
Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature. view more (2006-09-08)
New findings show a slow recovery from extreme global warming episode 55 million years ago
Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago, according to a study published this week in the journal... view more...

Tiny Marine Organisms Reflect Ocean Warming
Sediment cores collected from the seafloor off Southern California reveal that plankton populations in the Northeastern Pacific changed significantly in response to a general warming trend that started in the early 1900s. view more (2006-01-06)
Global warming will reduce ocean productivity, marine life
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans-the growth of phytoplankton that forms the basis for the rest of the marine food chain-is tightly linked to climate change, and would be reduced by global warming. view more (2006-12-07)
Arctic ice meltdown continues with significantly reduced winter ice cover
As far as temperatures drop in the Arctic winter - on average to -34°C (-29°F) - a new study shows that in the last two years sea ice is shrinking on the surface of Arctic waters to record low levels. view more (2006-09-14)
Ocean Noise Has Increased Considerably Since 1960s, According to New Scripps Analysis
Declassified Navy documents allow comparison that points to global shipping as the likely reason behind increase in undersea noise pollution Scripps Institution of Oceanography/UC San Diego. view more (2006-08-21)
Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia. view more (2005-12-20)
Marine Biology Mystery Solved: Function of "Unicorn" Whale's 8-foot Tooth Discovered
Today, Harvard School of Dental Medicine (HSDM) researcher Martin Nweeia, DMD, DDS, answers a marine science question that has eluded the scientific community for hundreds of years: why does the narwhal, or "unicorn," whale have an 8-foot-long tooth emerging from its head, and what is its function? view more (2005-12-14)
Global warming can trigger extreme ocean, climate changes
Newly published research results provide evidence that global climate change may have quickly disrupted ocean processes and lead to drastic shifts in environments around the world. view more (2006-01-05)
Microbe has huge role in ocean life, carbon cycle
Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell-and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. view more (2005-08-19)
How Did Continents Split? Geology Study Shows New Picture
Like pieces in a giant jigsaw puzzle, continents have split, drifted and merged again many times throughout Earth's history, view more (2006-05-24)
Volcanic eruptions, ancient global warming linked
A team of scientists announced today confirmation of a link between massive volcanic eruptions along the east coast of Greenland and in the western British Isles about 55 million years ago and a period of global warming that raised sea surface temperatures by five degrees (Celsius) in the tropics and more than six degrees in the Arctic. view more (2007-04-27)
Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks. view more (2007-09-11)
Seagrass Is In Decline Worldwide, Says UNH Researcher
Around the world, seagrass beds - shallow-water ecosystems that are important habitats, food sources, and sediment stabilizers - are in decline. view more (2006-03-28)
