Corals thriving despite acidic condition in remote Pacific bay
2014-02-26 00:12:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Scientists have discovered a small island bay in the Pacific which could serve as a peephole into the future of the ocean. Palau's Rock Island Bay harbors a naturally occurring anomaly its water is acidified as much as scientists expect the entire ocean to be by 2100 as a result of rising carbon dioxide emissions. Surprisingly, though, the bay is home to one of the healthiest coral reefs in the Pacific. Anywhere else in the world, water acidification results in decline and death of the corals....

Increasing Ocean Acidity Harming More Than Just Corals
2013-12-25 15:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The chemistry of the oceans is changing. And it isn't just the corals and the baby oysters that are unhappy. It makes juvenile rockfish really anxious, and it upsets the digestion of sea urchins. The pH (a measure of acidity -- the lower the pH, the more acid the water) of the planet's oceans is dropping rapidly, largely because the carbon dioxide levels in the atmosphere are increasing. Since carbon dioxide dissolves in water to form carbonic acid, the seas are responding to global change. The...

How Bacteria Figure Out When Corals Are Vulnerable
2013-12-14 03:19:00| Climate Ark Climate Change & Global Warming Newsfeed
Softpedia: A team of investigators at the Massachusetts Institute of Technology (MIT) announces the discovery of a mechanism that enables bacteria living in the world's oceans to attack and infect vulnerable corals. Coral reefs around the world are endangered by factors such as climate change, global warming and ocean acidification. The latter, in particular, is especially worrying, since it promotes coral bleaching. This phenomenon occurs when the algae that live in harmony with polyps inside corals...

Similar Corals Affected Differently by Warming Oceans
2013-12-13 04:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Softpedia: As global warming continues to progress, the world's oceans are becoming increasingly acidic, due to their inability to capture and store carbon dioxide at the rate we are releasing it into the atmosphere. This acidification is affecting similar corals in different ways, a new study demonstrated. The fact that climate change is endangering coral reefs around the world has been known for years, but thus far very few studies have been conducted on how resilience to warming waters and acidification...

Corals Make Chemical That Influences Local Climate
2013-10-25 01:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Anyone who has ever been to the ocean knows that signature smell of sea water. One of the molecules responsible for that smell is actually derived from a chemical made by tiny coral animals called dimethylsulphoniopropionate (DMSP). According to a new study in the journal Nature, Australian marine scientists have discovered the first evidence that DMSP plays a major role in local climate. The molecule offers the coral animals cellular protection in times of heat stress and causes climate cooling...
