Reign Of Acid Rain Is Far From Over
2012-07-26 05:46:01

New connection between climate change and acidification of Northeast's forests and streams Acid rain. It was a problem that largely affected U.S. eastern states. It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds--and rainfall--acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients. New England's sugar maples were among the trees left high and...

We Can Still Save Our Reefs

redOrbit Staff & Wire Reports - Your Universe Online John Pandolfi, along with 81 nations and 500 million people, keep hopeful that the world´s coral reefs are not in a lot of trouble. The world-famous coral scientist, from the ARC Centre of Excellence for Coral Reef Studies and University of Queensland, has traced the story of the world´s reefs over more than 50 million years and is translating delicate signals from the past to reveal what doomed them in previous...

Some coral reef fish may be better prepared to cope with rising CO2 in the world´s oceans — thanks to their parents. Researchers at the ARC Centre of Excellence for Coral Reef Studies (CoECRS) today reported in the journal Nature Climate Change, encouraging new findings that some fish may be less vulnerable to high CO2 and an acidifying ocean than previously feared. “There has been a lot of concern around the world about recent findings that baby fish are highly...

Scientists Use 'Lab-in-a-Box' To Study Coral Reefs
2012-06-08 05:04:39

In what is being called the first controlled ocean acidification experiment ever conducted in shallow coastal waters, an international team of experts has created a miniature laboratory in the Great Barrier Reef in order to simulate anticipated future conditions in the waters of the region's ecosystem. The researchers, including Stanford Woods Institute for the Environment Senior Fellows Jeff Koseff, Rob Dunbar and Steve Monismith, created a so-called "lab-in-a-box" in two to six foot deep...

End-Permian Crisis Recovery Took Earth 10 Million Years
2012-05-28 04:07:34

It took the Earth 10 million years to recover from a cataclysmic event that wiped out 90% of plant and animal life some 250 million years ago, according to new evidence presented Sunday in the journal Nature Geoscience. According to a press release detailing the research, Dr. Zhong-Qiang Chen of the China University of Geosciences in Wuhan and Professor Michael Benton from the University of Bristol discovered that biological recovery from what they dub "the greatest mass extinction of all...

Ocean Acidification Linked With Larval Oyster Failure in Hatcheries
2012-04-13 03:43:11

Increase in ocean acidification led to collapse of oyster seed production at Oregon hatchery Marine researchers have definitively linked the collapse of oyster seed production at a commercial oyster hatchery in Oregon to an increase in ocean acidification. Larval growth at the hatchery declined to a level considered by the owners to be "non-economically viable." A study by the scientists found that increased seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean...

Researchers at Oregon State University have definitively linked an increase in ocean acidification to the collapse of oyster seed production at a commercial oyster hatchery in Oregon, where larval growth had declined to a level considered by the owners to be “non-economically viable.” A study by the researchers found that elevated seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean water, inhibited the larval oysters from developing their shells and growing...

Corals may be better placed to cope with the gradual acidification of the world´s oceans than previously thought — giving rise to hopes that coral reefs might escape climatic devastation. In new research published in the journal Nature Climate Change, an international scientific team has identified a powerful internal mechanism that could enable some corals and their symbiotic algae to counter the adverse impact of a more acidic ocean. As humans release ever-larger amounts of...

The most comprehensive dataset of surface water carbon dioxide (CO2) measurements for the world's oceans and coastal seas is launched today by an international team of scientists led by the University of East Anglia (UEA). The Surface Ocean CO2 Atlas (SOCAT) comprises 6.3 million global observations made from research vessels, commercial ships and moorings around the world since 1968. The dataset documents the changes in ocean carbon similar to the Mauna Loa record — or 'Keeling...

Ocean Acidification Rapid Compared To Ancient Times
2012-03-02 13:49:09

The world´s oceans may be acidifying more rapidly than they have at any time in the past 300 million years due to high levels of pollution, according to research published this week in the journal Science. Researchers, led by Columbia University´s Lamont-Doherty Earth Observatory and the University of Bristol, assessed a number of climate change events in Earth´s history, including an asteroid impact that wiped out the dinosaurs 65 million years ago. They warn that too...

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...
