Provided by American Physiological SocietyAugust 5, 2010 Human impact is causing lower oxygen and higher carbon dioxide levels in coastal water bodies. Increased levels of carbon dioxide cause the water to become more acidic, having dramatic effects on the lifestyles of the wildlife that call these regions home. The problems are expected to worsen if […]
By Craig Welch, Seattle Times environment reporter July 31, 2010 at 8:36 PM DABOB BAY, Hood Canal — Inside the burbling tubs of the Taylor Shellfish hatchery here, oysters are incubating once again. But no one believes things are really back to normal. Several years after oyster larvae around the Northwest began dying by the […]
By Wynne Parry, Senior Writer29 July 2010 07:39 am ET One hundred days ago Thursday, the oil rig Deepwater Horizon began spewing oil into the Gulf of Mexico. As profoundly as the leak of millions of barrels of oil is injuring the Gulf ecosystem, it is only one of many threats to the Earth’s oceans […]
It may takes tens of thousands of years for oceans to recover from the acidity caused by increased levels of carbon dioxide By David Biello July 22, 2010 Single-cell life-forms thrive throughout the world’s oceans—and have for hundreds of millions of years. Tiny varieties known as calcareous nanoplankton build exuberant, microscopic shells—resembling wagon wheels, fishlike […]
Carbon dioxide emissions are making the oceans more acidic, imperiling the growth and reproduction of species from plankton to squid By Marah J. Hardt and Carl Safina “Slow sperm … now that’s a problem,” said Jonathan Havenhand, his British accent compounding the gravity of the message. “That means fewer fertilized eggs, fewer babies and smaller […]
Loss of sea ice is unlikely to enable Arctic waters to mop up more carbon dioxide from the air. By Hannah Hoag As climate scientists watched the Arctic’s sea-ice cover shrink year after year, they thought there might be a silver lining: an ice-free Arctic Ocean could soak up large amounts of CO2 from the […]
If you think the stars of Pixar’s Finding Nemo had it rough, spare a thought for the plight of real clownfish. These popular fish may struggle to survive in oceans that are becoming enriched with carbon dioxide. High levels of CO2 dissolved in the water can muddle a clownfish’s sense of smell, preventing it from […]
By Les Blumenthal | McClatchy NewspapersPosted on Sunday, July 4, 2010 WASHINGTON — A sobering new report warns that the oceans face a “fundamental and irreversible ecological transformation” not seen in millions of years as greenhouse gases and climate change already have affected temperature, acidity, sea and oxygen levels, the food chain and possibly major […]
Time series of (top) atmospheric CO2 and surface ocean pCO2 and (bottom) surface ocean pH at the atmospheric Mauna Loa Observatory (MLO) on the island of Hawai‘i and Station ALOHA in the subtropical North Pacific north of Hawai‘i, 1988–2008. Doney, 2010, adapted from Dore et al, 2009. Ocean acidification is documented clearly from ocean time-series […]
By Scott C. Doney Abstract: Climate change, rising atmospheric carbon dioxide, excess nutrient inputs, and pollution in its many forms are fundamentally altering the chemistry of the ocean, often on a global scale and, in some cases, at rates greatly exceeding those in the historical and recent geological record. Major observed trends include a shift […]
