Humanity's rising CO2 emissions could have a significant impact on the world's fish populations according to groundbreaking new research carried out in Australia. Baby fish may become easy meat for predators as the world's oceans become more acidic due to CO2 fallout from human activity, an international team of researchers has discovered. In a series of experiments reported in the latest issue of the Proceedings of the National Academy of Science (PNAS), the team found that as carbon levels...

Lack of sufficient iron may be a significant factor in controlling massive blooms of Emiliania huxleyi, a globally important species of marine algae or phytoplankton, according to research led by researchers at the National Oceanography Centre (NOC) in Southampton. Emiliania huxleyi is a species of coccolithophore found in oceans all around the world, from the tropics to the Arctic Ocean. Coccolithophore blooms often develop during the summer when a blanket of water called the thermocline...

The idea to sequester carbon is gaining support as a way to avoid global warming. For example, the European Union plans to invest billions of Euros within the next ten years to develop carbon capture and storage whereby CO2 will be extracted at power plants and other combustion sites and stored underground. But how effective is this procedure and what are the long-term consequences of leakage for the oceans and climate? A Niels Bohr Institute researcher has now cast light upon these issues....

Numerous studies are documenting the growing effects of climate change, carbon dioxide, pollution and other human-related phenomena on the world's oceans. But most of those have studied single, isolated sources of pollution and other influences. Now, a marine geochemist at the Woods Hole Oceanographic Institution (WHOI) has published a report in the latest issue of the journal Science that evaluates the total impact of such factors on the ocean and considers what the future might hold. "What...

NASA's first dedicated oceanographic field campaign goes to sea June 15 to take an up-close look at how changing conditions in the Arctic are affecting the ocean's chemistry and ecosystems that play a critical role in global climate change. The "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment" mission, or ICESCAPE, will investigate the impacts of climate change on the ecology and biogeochemistry of the Chukchi and Beaufort seas. A key focus is how changes in...

European Science Foundation presents ocean acidification report at EU Maritime Day 2010 Ten years ago, ocean acidification was a phenomenon only known to small group of ocean scientists. It's now recognized as the hidden partner of climate change, prompting calls for an urgent, substantial reduction in carbon emissions to reduce future impacts. The 'Impacts of Ocean Acidification' science policy briefing presented by the European Science Foundation on May 20 for European Maritime Day 2010...

WASHINGTON -- The changing chemistry of the world's oceans is a growing global problem, says the summary of a congressionally requested study by the National Research Council, which adds that unless man-made carbon dioxide (CO2) emissions are substantially curbed, or atmospheric CO2 is controlled by some other means, the ocean will continue to become more acidic. The long-term consequences of ocean acidification on marine life are unknown, but many ecosystem changes are expected to result....

Acidifying oceans dramatically stunt growth of already threatened shellfish As we prepare to celebrate Earth Day on April 22, we can add another species, one of widespread ecological and economic importance, to the list of the beleaguered. From East Coast to West and around the world, global warming and its effects have descended upon shellfish reefs, particularly those formed by the Olympia oyster. More than one-third of the world's human-caused carbon dioxide emissions have entered the...

The rise in human emissions of carbon dioxide is driving fundamental and dangerous changes in the chemistry and ecosystems of the world's oceans, international marine scientists warned today. "Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," the researchers say in the latest issue of the journal Trends in Ecology and Evolution (TREE). "This emphasizes the urgent need to adopt policies that drastically reduce CO2...

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...
