Species have come and gone at different rates than previously believed
Diversity among the ancestors of such marine creatures as clams, sand dollars and lobsters showed only a modest rise beginning 144 million years ago with no clear trend afterwards, according to an international team of researchers. This contradicts previous work showing dramatic increases beginning 248 million years ago and may shed light on future diversity.

Acidifying oceans add urgency to CO2 cuts
It's not just about climate change anymore. Besides loading the atmosphere with heat-trapping greenhouse gases, human emissions of carbon dioxide have also begun to alter the chemistry of the ocean. The ecological and economic consequences are difficult to predict but possibly calamitous, warn a team of chemical oceanographers, and halting the changes already underway will likely require even steeper cuts in carbon emissions than those currently proposed to curb climate change.

University of Hawaii researchers discover new pathway for methane production in the oceans
A new pathway for methane production has been uncovered in the oceans, and this has a significant potential impact for the study of greenhouse gas production on our planet. The article, released in the prestigious journal Nature Geoscience, reveals that aerobic decomposition of an organic, phosphorus-containing compound, methylphosphonate, may be responsible for the supersaturation of methane in ocean surface waters.

G8 summit: Opportunity for immediate action on climate change
German Chancellor Angela Merkel's recent pledge of 500 million Euros over four years to conserve tropical forests starts to address a major source of greenhouse gas emissions causing climate change. Germany's G8 partners -- the United States, Britain, Canada, France, Italy, Japan and Russia -- can take immediate action on climate change by making a similar commitment and promoting forest conservation as an important and viable way to reduce greenhouse gas emissions.

Penguins setting off sirens over health of world's oceans
Like the proverbial canary in the coal mine, penguins are sounding the alarm for potentially catastrophic changes in the world's oceans, and the culprit isn't only climate change, says a University of Washington conservation biologist.

Invisible waves shape continental slope
A class of powerful, invisible waves hidden beneath the surface of the ocean can shape the underwater edges of continents and contribute to ocean mixing and climate, researchers from the University of Texas at Austin have found.

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. Researchers from an expedition to the Gakkel Ridge, led by the American Woods Hole Oceanographic Institution, report in the current issue of the journal Nature that they discovered, with a specially developed camera, extensive layers of volcanic ash on the seafloor, which indicates a gigantic volcanic eruption.

Geologists discover signs of volcanoes blowing their tops in the deep ocean
A research team led by the Woods Hole Oceanographic Institution has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. Such violent eruptions of splintered, fragmented rock -- known as pyroclastic deposits -- were not thought possible at great ocean depths because of the intense weight and pressure of water and because of the composition of seafloor magma and rock.

Dry Tortugas show positive trends: Protected area slowly rebounding
Thirty-eight research divers from the University of Miami, NOAA Fisheries Service, the Florida Fish and Wildlife Conservation Commission, the National Park Service, REEF, and the National Undersea Laboratory recently completed a successful 20-day biennial census to measure how the protected status of the Florida Keys National Marine Sanctuary's Tortugas Ecological Reserve and Dry Tortugas National Park's Research Natural Area are helping the regional ecosystem rebound from decades of overfishing and environmental changes.

Tuna populations at risk
A historic meeting next week may decide the fate of tuna in the Eastern Pacific Ocean, one of the world's most important marine resources. The Inter-American Tropical Tuna Commission has an opportunity at its annual meeting June 23–27 in Panama City, Panama, to reverse a trend of inaction, and take concrete steps to stop the decline of tuna stocks. Failure of the IATTC to compromise effectively in the past has blocked the consensus required for the adopt ion of binding resolutions.

Ebb and flow of the sea drives world's big extinction events
If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits.
