Overfishing and disease have decimated shellfish populations in many of the world's temperate estuarine and coastal ecosystems. Smithsonian scientists, led by Whitman Miller, ecologist at the Smithsonian Environmental Research Center in Edgewater, Md., have discovered another serious threat to these valuable filter feeders"”rising levels of atmospheric carbon dioxide that contribute to the acidification of open ocean, coastal and estuarine waters. Their findings are being published in...

Drillship JOIDES Resolution completes first expedition as redesigned ship The Integrated Ocean Drilling Program (IODP) drillship JOIDES Resolution is returning to port in Honolulu this week after a two-month voyage to chart detailed climate history in the equatorial Pacific Ocean. The expedition was the first of two back-to-back voyages of a scientific project called Pacific Equatorial Age Transect (PEAT). It was the first international scientific drilling expedition after the JOIDES...

A $16 million program launched by the UK government will fund a five-year research study on ocean acidification, BBC News reported. Oceans are becoming more acidic as a result of CO2 from human activities being absorbed by seawater, researchers said, adding that acidification of the oceans will be one of the major environmental concerns of this century. The 5-year study will have researchers analyzing and assessing how marine ecosystems are affected in the Atlantic, Antarctic and Arctic...

New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. Concentrations of carbon dioxide are increasing rapidly in the Earth's atmosphere, primarily because of human activities....

Deep-sea corals from about 400 meters off the coast of the Hawaiian Islands are much older than once believed and some may be the oldest living marine organisms known to man. Researchers from Lawrence Livermore, Stanford University and the University of California at Santa Cruz have determined that two groups of Hawaiian deep-sea corals are far older than previously recorded. Using the Lab's Center for Accelerator Mass Spectrometry, LLNL researchers Tom Guilderson and Stewart Fallon used...

A U.S. biological oceanographer says acidification could be causing a slow-motion destruction of ocean ecosystems. Victoria Fabry, a visiting researcher at Scripps Institution of Oceanography at the University of California, San Diego, said tests show just 48 hours of exposure to slightly corrosive seawater causes mollusc shells to start to dissolve. The university said increasing levels of carbon dioxide could spell ecological disaster to industries dependent on the seas. About a third of...

A top ocean scientist warned that carbon dioxide emissions from human activities are acidifying the oceans and threatening some sea life with mass extinction, BBC New reported. It is impossible to know how marine life will cope, but it is feared that many species will not survive, according to Dr. Carol Turley from Plymouth Marine Laboratory. Researchers say CO2 emissions have already turned the sea about 30 percent more acidic since the Industrial Revolution and it is more acidic now...

A U.S. study suggests the world's coral reefs might begin dissolving if the Earth's atmospheric carbon dioxide content reaches double pre-industrial levels. Even today, rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, said scientists at the Carnegie Institution in Washington and the Hebrew University of Jerusalem. The researchers said reefs are being impacted by ocean acidification caused by the...

Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. A study to be published online March 13, 2009 in Geophysical Research Letters by researchers at the Carnegie Institution and the Hebrew University of Jerusalem warns that if carbon dioxide reaches double pre-industrial levels, coral reefs can be expected to not just stop growing, but also to begin dissolving all over the world. 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...

Rice Coral, (Montipora capitata), also known as Pore Coral, is a species of stony coral in the Acroporidae family. It is found in the tropical north and central areas of the Pacific Ocean at depths down to 66 feet. It is common in the waters near Hawaii, especially where the sea is turbulent. This is a reef-building species that forms colonies. As it matures, it develops tree-like branches. Its corallites are tiny and well separated by a calcareous (calcium carbonate) skeleton. The walls...
