By The Associated Press DES MOINES (AP) - Environmental groups in nine states petitioned the federal government on Wednesday to set and enforce pollution standards in the Mississippi River basin and the Gulf of Mexico.The petition to the U.S. Environmental Protection Agency followed Monday's announcement that the dead zone in the Gulf of Mexico is the second-largest to date at 8,000 square miles.The dead zone is an area of water where oxygen levels are too low to support marine life. It's...

Reefs may erode in areas with high carbon dioxide levels because the glue binding coral skeletons to larger reef structures is missing, a U.S. study says. The study found coral reefs in the eastern tropical Pacific Ocean offer a real-world example of the reef ecosystems will face under high carbon dioxide conditions resulting in ocean acidification, the National Oceanic and Atmospheric Administration said Thursday in a release. Derek Manzello, a coral reef ecologist at NOAA's Atlantic...

By Marla Dickerson / Los Angeles Times A few miles inland from the Pacific Ocean, amid cracked earth and mesquite and sun-bleached cactus, neat rows of emerald plants sprout from the desert floor. The crop is salicornia. It is nourished by seawater flowing from a man-made canal. And if you believe the American who is farming it, this incongruous swath of green has the potential to feed the world, fuel our vehicles and slow global warming. He is Carl Hodges, a Tucson, Ariz.-based...

More than 93 million years ago, researchers say undersea volcanic activity caused mass extinction in the worlds' oceans. During the late Cretaceous Period, the supposed "anoxic event" starved oxygen from the ocean depths and wiped out millions of marine organisms. Researchers from the University of Alberta, Canada, published their findings in the journal Nature. They found a telltale signature of underwater volcanism in rocks dating to the period. Researchers say during the undersea...

Scientists expect the Gulf of Mexico's so-called dead zone to increase to record levels this year due to ethanol use and massive Midwest flooding this season. The strip, which is located off the Texas and Louisiana coasts, could stretch to an unprecedented 8,800 square miles this year, according to scientists from the U.S. National Oceanic and Atmospheric Administration, Louisiana Universities Marine Consortium and Louisiana State University. That expectation would put the dead zone at almost...

It's summertime and people are flocking to the coasts around the country. But when summer storms arrive, it's not only beach-goers who are affected; the rains can also have an impact on living creatures far below the ocean surface. Summer storms sweep fertilizers into the rivers and streams and carry them to the shoreline. Once the plumes of storm and river runoff reach the coast, the nutrients in fertilizers can feed tiny ocean plants, called phytoplankton, which can bloom and create "dead...

By Robert Morris, The Sun News, Myrtle Beach, S.C. Jul. 13--Four years ago, area anglers watched the whole ocean turn on its head. Live minnows in bait buckets at the end of fishing piers died within minutes. Deepwater fish -- jack crevalle and ribbonfish -- suddenly started skirting the surf. Fish kills were reported, but strangest of all was the flounder. "It was weird. It was one right after another," said Ron Lovelace, who recalled that he and his friends caught 50 or 60...

By Dave Forster, The Virginian-Pilot, Norfolk, Va. Jul. 8--SUFFOLK -- The state is trying to figure out what all but wiped out the fish population of a 50-acre lake over the weekend. Residents around Sleepy Lake, a private lake in the northwestern part of the city, awoke Saturday to a blanket of dead fish on the water, said Dennis McBride, chairman of the lake and dam committee of the homeowner s association. "We don't know if we got a hundred percent fish kill -- but pretty damn...

GULFPORT - Mississippi scientists are watching for the possible spread of an area of oxygen-depleted water off the Louisiana coast that could move eastward. A recently released study suggests the dead zone could be more than 10,000 square miles this summer. It has averaged about 6,000 square miles since 1990. The dead zone forms as substances from farms, such as nitrogen and phosphorous, travel down the Mississippi River or one of its tributaries and into the Gulf of Mexico. The...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
