Mixed News For Pacific Northwest Oyster Industry In World Oceans Month
2013-06-13 10:38:01

National Science Foundation Ocean acidification inhibits shell formation, but interventions at hatcheries may offset some effects, scientists find For the past several years, it has struggled with significant losses due to ocean acidification. Oyster larvae have had mortality rates high enough to render production no longer economically feasible. Now a new study documents why oysters appear so sensitive to increasing acidity, but also offers some hope for the future. It isn't...

New CO2 Removal Technique Produces Green Fuel, Offsets Ocean Acidification
2013-05-29 10:31:52

April Flowers for redOrbit.com - Your Universe Online A new technique to remove and store atmospheric carbon dioxide has been demonstrated by scientists at the Lawrence Livermore National Laboratory (LLNL). The new technique also generates carbon-negative hydrogen and produces alkalinity, which can be used to offset ocean acidification. At laboratory scale, the team demonstrated a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral...

Lower Ocean Temperatures Key To Saving Coral Reefs
2013-05-14 14:27:34

Lee Rannals for redOrbit.com — Your Universe Online University of Bristol researchers writing in the journal Geophysical Research Letters say limiting global warming would be key to buying the coral reefs some more time. The researchers found restricting greenhouse warming to just 50-100 parts per million (ppm) carbon dioxide, or approximately half the increase since the Industrial Revolution, would avoid large-scale reductions in reef habitat occurring in the future. "If sea...

Effects Of Changing Ocean pH May Result In Increase In The Hearing Sensitivity Of Fish
2013-04-19 14:26:57

University of Miami Rosenstiel School of Marine & Atmospheric Science Ocean acidification, which occurs as CO2 is absorbed by the world's oceans, is known to negatively impact a wide variety of marine animals ranging from massive corals to microscopic plankton. However, there is much less information about how fish may be impacted by acidification, should carbon emissions continue to rise as a result of human activities. In a new study published in the Proceedings of the National...

Resilience In Shelled Plants Exposed To Ocean Acidification Found By Scientists
2013-04-15 11:35:10

University of California - Santa Barbara Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems. But a group led by a UC Santa Barbara professor has found a point of resilience in a microscopic shelled plant with a massive environmental impact, which suggests the future of ocean life may not be so bleak. As fossil fuel emissions increase, so does the amount of carbon dioxide oceans absorb and dissolve, lowering their pH levels. "As pH...

Sea Urchins Prepared For Future Climate Change
2013-04-10 05:47:43

[ Watch the Video: Ocean Babies on Acid - The Time Machine ] Lee Rannals for redOrbit.com - Your Universe Online Scientists have uncovered some surprising abilities in sea urchins living along the coast of California and Oregon. A group from Stanford discovered that some purple sea urchins have the ability to rapidly evolve in acidic ocean water, which is a skill that could come in handy as climate change increases. This ability allows urchins to have healthy growth in water with...

Microborers Represent New Threat To Earth’s Coral Reefs
2013-03-18 11:42:49

Brett Smith for redOrbit.com - Your Universe Online Previous studies have shown that warming oceans and ocean acidification threaten to destroy the ocean´s coral reefs. Now, a new study from Australian researchers published in the journal Global Change Biology suggests that yet another threat could decimate these delicate ecosystems. “Our research shows that when seawater is both acidic and warm — which is predicted to happen under future climate scenarios — coral...

Unique Experiment Uses Huge Plastic Containers To Study Ocean Acidification
2013-03-13 16:08:19

AlphaGalileo Foundation To study the effects of ocean acidification, ten huge plastic containers called mesocosms are placed in the Gullmar Fjord in Sweden. The project is unique: mesocosms of this size have never been used for such a long period of time. The experiment is part of a worldwide research project, and includes researchers from the University of Gothenburg, Sweden. This is the largest and longest experiment on the impact of climate change on marine ecosystems that have been...

How Sensitive US East Coast Regions May Be To Ocean Acidification Revealed By New Study
2013-03-01 12:17:31

Woods Hole Oceanographic Institution A continental-scale chemical survey in the waters of the eastern U.S. and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity. The study, which measures varying levels of carbon dioxide (CO2) and other forms of carbon in the ocean, was conducted by scientists from 11 institutions across the U.S. and was published in the journal Limnology and Oceanography. “Before now, we haven't had a very...

Researchers from the University of Bonn found out that tiny foraminifera in the oceans can save islands The climate is getting warmer, and sea levels are rising — a threat to island nations. As a group of researchers lead by colleagues from the University of Bonn found out, at the same time, tiny single-cell organisms are spreading rapidly through the world's oceans, where they might be able to mitigate the consequences of climate change. Foraminifera of the variety Amphistegina are...

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...
