Latest Ocean acidification Stories

Ocean Acoustics Changing
2012-10-19 14:07:43

Brett Smith for redOrbit.com - Your Universe Online Along with negatively impacting marine life and global climate change, the acidification of the Earth´s oceans could have the unintended side effect of changing the acoustics beneath the water´s surface. New research suggests that a future, more acidic ocean would resemble the one that existed around 110 million years ago, when dinosaurs still roamed both the land and sea. Climatologists have been raising concerns in recent...

Acidification Recorder Recovered From Antarctic Waters
2012-10-19 11:32:26

April Flowers for redOrbit.com - Your Universe Online A National Science Foundation (NSF) supported research team retrieved data from a sensor in Antarctic waters that they hope will provide critical baseline data for the acidification, or chemical changes, in those remote seas. Led by Gretchen Hofmann — professor of ecology, evolution and marine biology at the University of California, Santa Barbara (UCSB) — the all female team retrieved the sensor earlier this month...

Carbon dioxide (CO2) released into the oceans as a result of water pollution by nutrients – a major source of this greenhouse gas that gets little public attention – is enhancing the unwanted changes in ocean acidity due to atmospheric increases in CO2. The changes may already be impacting commercial fish and shellfish populations, according to new data and model predictions published today in ACS's journal, Environmental Science & Technology. William G. Sunda and Wei-Jun...

Coral Reefs Will Suffer If Climate Change Goes Unchecked
2012-09-17 12:17:18

Brett Smith for redOrbit.com - Your Universe Online Time may be running out for the world´s coral reefs which could be severely victimized by rising global temperatures and carbon dioxide levels, according to a new report in Nature Climate Change. "Our findings show that under current assumptions regarding thermal sensitivity, coral reefs might no longer be prominent coastal ecosystems if global mean temperatures actually exceed 2 degrees Celsius (3.6 Fahrenheit) above the...

Life in the world´s oceans faces far greater change and risk of large-scale extinctions than at any previous time in human history, a team of the world´s leading marine scientists has warned. The researchers from Australia, the US, Canada, Germany, Panama, Norway and the UK have compared events which drove massive extinctions of sea life in the past with what is observed to be taking place in the seas and oceans globally today. Three of the five largest extinctions of the past...

Unless Drastic Protection Policies Are Put In Place Marine Species Are At Risk
2012-08-21 13:56:55

redOrbit Staff & Wire Reports - Your Universe Online If the levels of carbon dioxide continue to increase many marine species will be harmed or won't survive It is doubtful that the current protection policies and management practices will be enough to save them. If various marine species are to survive, unconventional, non-passive methods to conserve marine ecosystems need to be considered. A group of scientists led by University of California, Santa Cruz researcher and...

Impact On Shellfish From Ocean Acidification
2012-08-06 14:24:57

redOrbit Staff & Wire Reports - Your Universe Online In the journal Global Change Biology, a worldwide study is published to understand and forecast the likely impact of ocean acidification on shellfish and other marine life living in seas from the tropics to the north and south poles. Ocean acidification is occurring because some of the increased carbon dioxide humans are adding to the atmosphere dissolves in the ocean and reacts with water to produce an acid. According to the...

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
2012-07-11 10:41:40

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...

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...
