Ocean Acidification

Ocean acidity affects fish senses. Acidic ocean conditions can disrupt orange clownfish larvae's ability to distinguish and respond to olfactory cues that help them locate a suitable adult habitat in a coral reef, according to a new study. Chemical & Engineering News. 10 February 2009
Academic calls for urgent action to save Barrier Reef. A University of Queensland professor says Australia is a step closer to protecting the Great Barrier Reef, but more needs to be done to address climate change. Ove Hoegh-Guldberg says carbon emissions need to be drastically reduced to save the Great Barrier Reef. ABC News. 09 February 2009
Scientists warn of acid's corrosive effect on shellfish. Experts at a symposium on climate change testified yesterday to a number of scenarios that could strike Massachusetts as oceans rise and warm, but one stood out. Cape Cod Times. 06 February 2009
First deep sea observatory studies climate change. The so-called Eye-in-the-Sea camera would be added to the first observatory operating in deep sea water and become part of a new kind of scientific exploration to assess the impacts of climate change on marine life. Associated Press. 05 February 2009
Females turn into males when times get tough... on the sea floor, that is. Japanese sea corals engage in "sex switching" under periods of stress, especially when threatened by global warming, a Tel Aviv University professor has found. Jerusalem Post. 04 February 2009
Nemo could get lost in acidifying seawater. In new lab experiments, orange clown fish larvae didn’t respond normally to scent when researchers reared them in more acidic seawater. Ocean chemists predict that the current increase in atmospheric carbon dioxide from human activity is lowering the pH. Science News. 03 February 2009
Clownfish lost at sea due to rising carbon dioxide levels. Tests on clownfish larvae showed they became disoriented and were unable to find a suitable place to live if they were raised in seawater that had absorbed carbon dioxide from the atmosphere. London Guardian. 03 February 2009
Acid oceans no laughing matter for clownfish. Just a few days after 150 marine scientists signed a declaration to draw attention to rising ocean acidity – dubbed "global warming's evil twin" – an international team has reported the first example of the potential for acid seas to directly affect animal behaviour. New Scientist. 03 February 2009
Disease, aided by global warming, threatens coral reefs. The coral reefs of the Caribbean are an underwater paradise of life and color. But there's trouble in paradise. And a scientist at the Woods Hole Oceanographic Institution sees global warming as a key culprit in turning that paradise into a dead zone. Cape Cod Today. 31 January 2009
Acid oceans 'need urgent action'. The world's marine ecosystems risk being severely damaged by ocean acidification unless there are dramatic cuts in CO2 emissions, warn scientists. BBC. 31 January 2009
Ocean acidification threatens New Zealand paua, mussels. Global warming's evil twin, the increasing acidification of carbon dioxide-saturated oceans is threatening New Zealand's corals, crustaceans and shellfish. Otago Daily Times. 31 January 2009
CO2 pollution makes oceans more acid. Carbon dioxide emissions must fall sharply to avoid inflicting acid damage to the world's marine ecosystems, more than 150 scientists warned on Friday. Agence France-Presse. 31 January 2009
Rising acidity threatens oceans. An international panel of marine scientists says oceanic acidity is accelerating so fast it threatens the survival of coral reefs, shellfish and the marine food web generally. New York Times. 30 January 2009
Crackdown on reef pollution. Australia announced a crackdown on pollution of the Great Barrier Reef on Thursday as the World Heritage-listed site comes under increasing threat from toxic chemicals and climate change. Agence France-Presse. 29 January 2009
Avery Point professor studies world being altered by climate change. Over the past 25 years, associate professor Peter Auster, whose research focuses on reef fishes, fish behavior and fisheries management and related areas, has witnessed a disturbing transformation of the Bonaire reefs. New London Day. 25 January 2009
Weird finds in ultra-deep Australian seas. Bizarre carnivorous sea squirts, large spider-like creatures and an ancient fossilised coral reef have all been found in a voyage into ultra-deep Australian waters. But for the scientists one of their most bizarre discoveries was what they did not find on the ocean floor. Australian Associated Press. 19 January 2009
Deep-sea sub discovers new animals off Australia. A deep sea submarine exploration off Australia's southern coast has discovered new species of animals and more evidence of the destructive impact of the greenhouse gas carbon dioxide on deep-sea corals. Reuters. 18 January 2009
Fish are crucial in oceanic carbon cycle. Fish may play a more important role in the marine carbon cycle than previously thought and might explain whey ocean surface waters are less acidic than models have predicted, a new study finds. Nature. 17 January 2009
Fish 'an ally' against climate change. An unlikely ally may have been found in the fight against the effects of climate change. Fish excretions seem to play a key role in maintaining the ocean's delicate pH balance, says a study that also reveals that there are 2 billion tonnes of fish in the world's oceans. New Scientist. 17 January 2009
Bangor scientists' global warming warning. Scientists at Bangor University yesterday warned that the ocean’s ability to absorb harmful greenhouse gases could be ebbing away. North Wales Daily Post. 14 January 2009
