Ocean Acoustics Changing
2012-10-19 14:07:43

Brett Smith for redOrbit.com - Your Universe Online Along with negatively impacting marine life and global climate change, the acidification of the Earth´s oceans could have the unintended side effect of changing the acoustics beneath the water´s surface. New research suggests that a future, more acidic ocean would resemble the one that existed around 110 million years ago, when dinosaurs still roamed both the land and sea. Climatologists have been raising concerns in recent...

Navy Looks To The Seas For Fueling The Fleet
2012-09-24 15:36:37

Refueling U.S. Navy vessels, at sea and underway, is a costly endeavor in terms of logistics, time, fiscal constraints and threats to national security and sailors at sea. In Fiscal Year 2011, the U.S. Navy Military Sea Lift Command, the primary supplier of fuel and oil to the U.S. Navy fleet, delivered nearly 600 million gallons of fuel to Navy vessels underway, operating 15 fleet replenishment oilers around the globe. From Seawater to CO2 Scientists at the U.S. Naval Research...

Carbon dioxide (CO2) released into the oceans as a result of water pollution by nutrients – a major source of this greenhouse gas that gets little public attention – is enhancing the unwanted changes in ocean acidity due to atmospheric increases in CO2. The changes may already be impacting commercial fish and shellfish populations, according to new data and model predictions published today in ACS's journal, Environmental Science & Technology. William G. Sunda and Wei-Jun...

Lee Rannals for redOrbit.com - Your Universe Online A new expedition is set to get a better picture of how salt content fluctuates in the ocean's upper layers, and how it shifts rainfall patterns. The NASA-sponsored expedition called the Salinity Processes in the Upper Ocean Regional Study (SPURS) will provided new data to help calibrate the salinity measurements NASA's Aquarius instrument has been collecting from space since August 2011. SPURS scientists will hop aboard the vessel...

Unless Drastic Protection Policies Are Put In Place Marine Species Are At Risk
2012-08-21 13:56:55

redOrbit Staff & Wire Reports - Your Universe Online If the levels of carbon dioxide continue to increase many marine species will be harmed or won't survive It is doubtful that the current protection policies and management practices will be enough to save them. If various marine species are to survive, unconventional, non-passive methods to conserve marine ecosystems need to be considered. A group of scientists led by University of California, Santa Cruz researcher and...

Impact On Shellfish From Ocean Acidification
2012-08-06 14:24:57

redOrbit Staff & Wire Reports - Your Universe Online In the journal Global Change Biology, a worldwide study is published to understand and forecast the likely impact of ocean acidification on shellfish and other marine life living in seas from the tropics to the north and south poles. Ocean acidification is occurring because some of the increased carbon dioxide humans are adding to the atmosphere dissolves in the ocean and reacts with water to produce an acid. According to the...

Reign Of Acid Rain Is Far From Over
2012-07-26 05:46:01

New connection between climate change and acidification of Northeast's forests and streams Acid rain. It was a problem that largely affected U.S. eastern states. It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds--and rainfall--acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients. New England's sugar maples were among the trees left high and...

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...
