Coral Reef Protection From Cloud Seeding
2013-07-11 04:51:24

April Flowers for redOrbit.com - Your Universe Online New research from the University of Leeds reveals threatened coral reefs could be protected from bleaching by warming oceans. The study proposes a targeted version of the geoengineering technique known as Marine Cloud Brightening (MCB) - seeding the clouds to cool sea surface temperatures - could give coral a fifty year "breathing space" to recover from acidification and warming. "Coral bleaching over the last few decades has been...

Ocean Acidification Has Transformed Delicate Ecosystem
2013-07-09 15:43:58

Brett Smith for redOrbit.com - Your Universe Online While many studies have focused on how ocean acidification may impact various individual species, an international team of researchers has just published a study on how an entire ecosystem can be affected by a more acidic ocean. As one of the consequences of climate change, ocean acidification is expected to significantly increase if carbon emissions continue at current rates. According to the study, which was published in...

Ocean Springs Indicate Coral Response To Acidification
2013-06-18 10:29:16

April Flowers for redOrbit.com - Your Universe Online The density of coral skeletons will be reduced by ocean acidification due to rising carbon dioxide levels, according to an international group of scientists led by the University of California, Santa Cruz. The study, published in Proceedings of the National Academy of Sciences, focused on corals growing where submarine springs naturally lower the pH of seawater. The findings of this study are the first to show corals are not able to...

Purple Urchins Quickly Adapt To Acidic Oceans
2013-06-13 11:41:25

Brett Smith for redOrbit.com - Your Universe Online As the levels of atmospheric carbon dioxide increase, the oceans are projected to absorb more of the greenhouse gas, leading to acidification of the water. This shift in oceanic chemistry is expected to negatively impact countless species. However, a new study from the University of California, Santa Barbara has found that purple sea urchins Strongylocentrotus purpuratus are capable of evolving in a way that copes with potential...

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...

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...
