Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahānaumokuākea Marine National Monument. Six of these species may represent entirely new genera, a remarkable feat given the broad classification a genus represents. A genus is a major category in the classification of organisms, ranking above a species and below a family. Scientists expect to identify more new species as...

NEW YORK, Feb. 19 /PRNewswire/ -- Imagine a world without fish. A new documentary on climate change and the oceans proposes just that. The film, A Sea Change, premieres at the DC Environmental Film Festival March 14. A Sea Change is the first documentary about ocean acidification, the underbelly of climate change, a little-known but potentially devastating threat to ocean life. The screening takes place at 3:30 pm in Baird Auditorium, at the National Museum of Natural History, at the...

Greenhouse gases are putting oceans at risk of becoming too acidic to support reefs and marine life, scientists at a U.N. forum in Monaco warned Friday. More than 150 scientists called on governments to take immediate action to reduce carbon dioxide emissions in the Monaco Declaration on Ocean Acidification drafted during the conference, the United Nations said in a news release. In the declaration, the marine scientists from 26 countries said acidity levels were accelerating and their...

The oceans of the world act as a shock absorber for the effects of climate change - absorbing a sizeable amount of the greenhouse gas carbon dioxide, according to a New York Times report. However, this assistance comes with a price: as the gas dissipates, it causes the seawater to become more acidic. As a result, an international board of marine scientists state that this acidity is growing so rapidly that it hurts the chances of the continued existence of coral reefs, shellfish and the...

Making bales with 30 percent of global crop residues "“ the stalks and such left after harvesting "“ and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. That is a significant amount of carbon, the process can be accomplished with existing technology and it can be done year after year, according to Stuart Strand, a University of Washington research...

Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. In shallow coastal regions, these zones can be caused by runoff of excess fertilizers from farming. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean by a factor of 10 or more. Whereas some coastal...

A scientific voyage off Australia's southern coast has found new species of animals and more evidence of the destructive impact of the greenhouse gas carbon dioxide on deep-sea corals. The U.S. and Australian researchers explored a vertical slice in the earth's crust known as the Tasman Fracture Zone, which drops from approximately 1.2 miles to more 2.5 miles deep. "We set out to search for life deeper than any previous voyage in Australian waters," said Ron Thresher from Australia's...

An international team of scientists has solved a mystery that has puzzled marine chemists for decades. They have discovered that fish contribute a significant fraction of the oceans' calcium carbonate production, which affects the delicate pH balance of seawater. The study gives a conservative estimate of three to 15 percent of marine calcium carbonate being produced by fish, but the researchers believe it could be up to three times higher.Published January 16th in Science, their findings...

Madison, WI, January 12, 2009 "“ Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effects of acidic deposition to the recovery of these aquatic and terrestrial ecosystems. Regional-scale studies have focused primarily on aquatic systems and while many of these ecosystems are showing signs of chemical recovery (increases in acid neutralizing...

Concern about increasing ocean acidification has often focused on its potential effects on coral reefs, but broader disruptions of biological processes in the oceans may be more significant, according to Donald Potts, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, and an expert in coral reef ecology and marine biodiversity. Potts gave an invited talk on "Geobiological Responses to Ocean Acidification" at the Fall Meeting of the American...

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...
