Changes in ocean chemistry "” a consequence of increased carbon dioxide (CO2) emissions from human industrial activity "” could cause U.S. shellfish revenues to drop significantly in the next 50 years, according to a new study by researchers at the Woods Hole Oceanographic Institution (WHOI).Intensive burning of fossil fuels and deforestation over the last two centuries have increased CO2 levels in the atmosphere by almost 40 percent. The oceans have absorbed about one-third of...

Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life, report the authors of a new study in the journal Geophysical Research Letters*. The culprit is atmospheric carbon dioxide, which even in a cooler globe will continue to be absorbed by seawater,...

Canadian zoologists have determined elevated water temperatures and high carbon dioxide concentrations can boost the growth of a species of sea star. The University of British Columbia scientists said their study is one of the first to look at the impact of ocean acidification on marine invertebrates that don't have a large calcified skeleton or external shell. The researchers said their findings challenge current assumptions about the potential impact of climate change on marine species. The...

Dozens of the world's top scientific academies urged the United Nations on Monday to include the issue of ocean acidification in upcoming discussions aimed at establishing a global climate change treaty. Their appeal coincided with the start of a 12-day meeting in Bonn under the banner of the U.N. Framework Convention on Climate Change (UNFCCC).  The group is tasked with guiding 192 parties towards a climate change agreement in Copenhagen in December that will establish targets for...

Possible job cuts and revenue loss as a result of ocean acidificationOcean acidification, a direct result of increased CO2 emission, is set to change the Earth's marine ecosystems forever and may have a direct impact on our economy, resulting in substantial revenue declines and job losses.Intensive fossil-fuel burning and deforestation over the last two centuries have increased atmospheric CO2 levels by almost 40%, which has in turn fundamentally altered ocean chemistry by acidifying surface...

Disruptions causing decline of coral reefs around the world Corals, it appears, have a genetic complexity that rivals that of humans, have sophisticated systems of biological communication that are being stressed by global change, and are only able to survive based on proper function of an intricate symbiotic relationship with algae that live within their bodies, say researchers in a paper published in this week's issue of the journal Science. Disruptions in these biological and communication...

U.S. marine scientists say they have discovered that rising levels of atmospheric carbon dioxide are threatening shellfish populations in many ecosystems. The researchers, led by ecologist Whitman Miller of the Smithsonian Environmental Research Center, said the increasing CO2 levels are contributing to the acidification of open ocean, coastal and estuarine waters. For shellfish and other organisms having calcium carbonate shells and structures, the problem begins when atmospheric CO2...

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...

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...
