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...

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...

Salinity Levels In Atlantic Ocean Are Off The Chart, According To NASA Instrument
2013-02-28 12:35:28

WATCH VIDEOS: [Aquarius Measuring Salty Seas 1] - [Aquarius Measuring Salty Seas 2] Lawrence LeBlond for redOrbit.com - Your Universe Online The salinity level of the world´s rivers, lakes and oceans has been a growing topic in response to global climate change. As NASA´s Aquarius instrument has shown previously, seasonal salinity has been on the rise in oceans all around the world. This year, the picture is no less striking, with deep shades of oranges and reds, at least in...

Ancient And Modern Tiny Marine Algae Provide Climate Change Clues
2013-02-04 10:21:39

National Oceanography Centre, Southampton (UK) Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow. Coccolithophores, a type of plankton, are not only widespread in the modern ocean but they are also prolific in the fossil record because their tiny calcium carbonate shells are...

Warming Oceans Will Play Major Role In Less Phytoplankton Diversity
2012-10-26 07:33:14

Lawrence LeBlond for redOrbit.com - Your Universe Online Phytoplankton (plant wanderers), organisms that exist in the sunlit layer of the world´s oceans, are important for the sustainability of the aquatic food web. However, future warming oceans could significantly alter the populations of these important organisms, further impacting climate change. Since phytoplankton play a major role in the food chain and the world´s carbon, nitrogen and phosphorous cycles, a significant...

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...

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...
