The 1918-1919 El Nino
February 8, 2010 | NOAA Watch

A recent computer model by NOAA-funded researchers indicates that the 1918-1919 El Niño was one of the strongest of the 20th Century. It has been linked to extreme weather events and the influenza pandemic of 1918 that killed over 25 million people. (NOAA technical report.)

The Costs of Ocean Acidification
January 23, 2010 | Woods Hole Oceanographic Institution

“The increasing acidification of the oceans is measured in pH units, but its impacts on people will be measured in dollar signs. Commercial and recreational fishing, tourism, the protection of shorelines by coral reefs—all could be harmed by ocean acidification.” Quoted from the WHOI press release.

Injecting Carbon Dioxide into the Ocean?
January 23, 2010 | Woods Hole Oceanographic Institution

“One proposed strategy to offset rising levels of greenhouse gases in our atmosphere is to capture carbon dioxide emissions from fossil-fuel-burning power plants and pump them into the ocean depths.” Quoted from the WHOI press release.

Carbon
Echinoderms Sequester Tons of Carbon
January 14, 2010 | National Oceanography Centre, Southampton

Echinoderms (like brittle stars and sea urchins) sequester carbon; their bodies absorb carbon, and their remains are buried under seafloor sediment, storing the carbon in the ocean floor. The amount of carbon sequestered by the vast numbers of these organisms may be greatly underestimated.

Atmosphere Affects Seafood Shells
December 3, 2009 | Woods Hole Oceanographic Institution

Increased amounts of carbon dioxide in the atmosphere can cause ocean acidification, which in turn affects aquatic life. Some “seafood” organisms – such as crabs, lobster, and shrimp – create more shell material in response to rising CO2 levels. Other organisms’ shells – like those of clams, urchins, and conchs – start to weaken, leaving them vulnerable to predation.

Younger Dryas Occurred Abruptly
December 1, 2009 | European Science Foundation

Isotopes in a mud core from Lough Monreach, Ireland, show that the Younger Dryas may have occurred very abruptly. When glacial Lake Agassiz flowed into the North Atlantic Ocean almost 13,000 years ago, the “Big Freeze” set in at once, possibly chilling the ocean within mere months. Could a rapid melting of the Greenland ice sheet in current times could produce a similar effect?
