Carbon Dioxide Emissions Keep Conch Snails From Escaping Predation
2014-01-07 13:18:57

Brett Smith for redOrbit.com - Your Universe Online New research from an international team of scientists has found that if more carbon dioxide makes its way into the ocean – conch snails will be more vulnerable to predation. Conch snails typically use a strong foot-like appendage to leap away from approaching predators. According to the team’s study, published in the Proceedings of the Royal Society B: Biological Sciences, when the snails are exposed to carbon dioxide levels...

Fluctuation 'adds insult to injury' for marine creatures A new Duke University-led study has documented dramatic, natural short-term increases in the acidity of a North Carolina estuary. "The natural short-term variability in acidity we observed over the course of one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms that are especially susceptible to changes in...

Sea-Level Rise Will Continue To Fuel Destructive Coastal Flooding
2013-12-05 10:26:23

April Flowers for redOrbit.com - Your Universe Online Two new literature review studies, published in Nature, reveal changing coastal ocean functions. The first study, "Coastal flooding by tropical cyclones and sea-level rise," reveals that the clamor about whether climate change will cause increasingly destructive tropical storms may be overshadowing a more unrelenting threat to coastal property: sea-level rise. Jonathan D. Woodruff, an assistant professor of sedimentology and...

Anxiety In Fish Caused By Rising Ocean Acidification
2013-12-04 19:35:14

Scripps Institution of Oceanography, UC San Diego Study shows acidity levels projected by the end of the century results in behavioral changes that could impact feeding, fisheries A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish. A growing base of scientific evidence has shown that the absorption of human-produced carbon dioxide...

Ocean Acidity Having Major Impact On Arctic Food Web Species
2013-12-03 06:27:12

April Flowers for redOrbit.com - Your Universe Online Tiny crustaceans, known as copepods, live just beneath the surface of the ocean. A research expedition to the Arctic, part of the Caitlin Arctic Survey, found that these tiny animals are more likely to battle for survival if ocean acidity continues to rise. The study, published in Proceedings of the National Academy of Sciences (PNAS), revealed that copepods that move large distances, migrating vertically across a wide range of pH...

Substantial costs expected from coral reef loss and declines in shellfisheries; Cold water corals also at risk In a major new international report, experts conclude that the acidity of the world's ocean may increase by around 170% by the end of the century bringing significant economic losses. People who rely on the ocean's ecosystem services – often in developing countries - are especially vulnerable. A group of experts have agreed on 'levels of confidence' in relation to ocean...

New Generation Of Micro Sensors Developed For Monitoring Ocean Acidification
2013-11-13 14:14:45

National Oceanography Centre, Southampton (UK) The first step in developing a cost-effective micro sensor for long-term monitoring of ocean acidification has been achieved by a team of scientists and engineers. The new technology, that will measure pH levels in seawater, was developed by engineers from the National Oceanography Centre, in close collaboration with oceanographers from University of Southampton Ocean and Earth Science, which is based at the center. The team successfully...

XPRIZE Foundation Reveals Competitions Geared Toward Ocean Health
2013-10-23 14:48:30

Brett Smith for redOrbit.com - Your Universe Online Known for spurring innovations in the commercial space industry, the XPRIZE Foundation has announced that it will launch a new series of competitions for innovations in ocean conservation technology. “As a result of human activity, the ocean is overfished, polluted, and exploited; a problem because it supports all life on Earth,” the Foundation said in a statement. “As governments around the world steadily reduce research and...

U.S. National Oceanic and Atmospheric Administration (NOAA) has awarded a Phase II - Small Business Innovative Research (SBIR) grant to Polestar Technologies to develop methods of monitoring ocean acidification and coral reef decimation. Needham Heights, MA (PRWEB) September 28, 2013 The rapid decline of living coral reefs has been a major concern of oceanographers and aqua-agriculturists worldwide. The well-being of our planet is directly related to the health of our oceans. The White...

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...
