First buoy to monitor ocean acidification launched
The first buoy to monitor ocean acidification has been launched in the Gulf of Alaska. Attached to the 10-foot-diameter buoy are sensors to measure climate indicators.   view more (2007-06-13)

Oceans may soon be more corrosive than when the dinosaurs died
Increased carbon dioxide emissions are rapidly making the world's oceans more acidic and, if unabated, could cause a mass extinction of marine life similar to one that occurred 65 million years ago when the dinosaurs disappeared.   view more (2006-02-21)

Ocean acidification -- another undesired side effect of fossil fuel-burning
Up to now, the oceans have buffered climate change considerably by absorbing almost one third of the worldwide emitted carbon dioxide. The oceans represent a significant carbon sink, but the uptake of excess CO2 stemming from man's burning of fossil fuels comes at a high cost: ocean acidification.   view more (2008-05-22)

Pacific coast turning more acidic
An international team of scientists surveying the waters of the continental shelf off the West Coast of North America has discovered for the first time high levels of acidified ocean water within 20 miles of the shoreline, raising concern for marine ecosystems from Canada to Mexico.   view more (2008-05-23)

Oceans turning to acid from rise in CO2
A report issued by the Royal Society in the U.K. sounds the alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine life in ways we can't anticipate," commented Dr. Ken Caldeira, co-author of the... view more (2005-07-01)

Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and... view more (2007-09-10)

Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today.   view more (2007-12-11)

Cranking up the volume-- Sounds travel farther underwater as world's oceans become more acidic
It is common knowledge that the world's oceans and atmosphere are warming as humans release more and more carbon dioxide into the Earth's atmosphere. However, fewer people realize that the chemistry of the oceans is also changing--seawater is becoming more acidic as carbon dioxide from the... view more (2008-09-30)

Regardless of global warming, rising CO2 levels threaten marine life
Like a piece of chalk dissolving in vinegar, marine life with hard shells is in danger of being dissolved by increasing acidity in the oceans.   view more (2007-03-09)

Air pollution from ships - a serious threat
Emissions from ships may bring as much nitrogen oxide to the atmosphere as the total amount of emissions coming from the USA. International shipping along the Norwegian coast and in the Northern Atlantic Ocean contributes largely to the formation of ground-level ozone and acidification of the... view more (2004-03-30)

Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans.   view more (2006-04-03)

Seabird Ammonia Emissions Contribute to Atmospheric Acidity
Ammonia emissions from seabirds have been shown to be a significant source of nitrogen in remote coastal ecosystems, contributing to nutrient enrichment (eutrophication) and acidification in ecosystems.   view more (2008-09-23)

Acidification of the sea hampers reproduction of marine species
By absorbing carbon dioxide from the atmosphere, and from the human use of fossil fuels, the world's seas function as a giant buffer for the Earth's life support system.   view more (2008-07-30)

Acid Soils in Slovakia Tell Somber Tale
Increasing levels of nitrogen deposition associated with industry and agriculture can drive soils toward a toxic level of acidification, reducing plant growth and polluting surface waters, according to a new study published online in Nature Geoscience.   view more (2008-11-18)

New findings show a slow recovery from extreme global warming episode 55 million years ago
Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago,... view more (2005-06-10)

Mixing it, Southern Ocean style
Sea water being churned in the ocean off Antarctica may be having a greater effect on global patterns of ocean movement than previously thought, according to new research reported in this week's edition of the international journal Science (9 January 2004).   view more (2004-01-05)

Database shows effects of acid rain on microorganisms in Adirondack Lakes
Prior to the federal Clean Air Act, unhindered industrial emissions were released into the air throughout the Midwestern and Eastern United States for decades. Many of those harmful chemicals came right back down to earth in the form of acid rain, a chemical concoction that includes nitric and... view more (2008-06-24)

Corals and Climate Change
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals.   view more (2007-08-23)

Report Warns about Carbon Dioxide Threats to Marine Life
Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and support oceanic biodiversity.   view more (2006-07-06)

Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage.   view more (2007-11-07)

Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have... view more (2008-09-23)

Indian eddies supply Atlantic Ocean with warm water
Water from the Indian Ocean does not reach the South Atlantic Ocean continuously, but in separate packages. These are called Agulhas eddies, after the current along the east coast of Southern Africa where they originate from.   view more (2005-10-11)

First map of threats to marine ecosystems shows all the world's oceans are affected
As vast and far-reaching as the world's oceans are, every square kilometer is affected by human activities, according to a study in the journal Science by researchers at the University of North Carolina at Chapel Hill and others.   view more (2008-02-15)

Climate change will affect carbon sequestration in oceans, model shows
The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the effects of global warming.   view more (2005-09-08)

Modeling of long-term fossil fuel consumption shows 14.5 degree hike in temperature
If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day.   view more (2005-12-07)
