(A) Surface distributions of Ω aragonite, S, fraction of sea ice meltwater (f SIM), and TA in surface water observed between depths of 0 and 20 m. f SIM was estimated by using 18O and S measurements (12, 13). Gray contour lines indicate isobaths of 1000, 2000, and 3000 m. (B) Relationship between Ω aragonite […]
As the Bluff oyster industry watches for hopeful signs of recovery, oyster fishers in the US are witnessing cause for concern, Craig Welch, of The Seattle Times, reports. The collapse began rather unspectacularly. In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, the shellfish growers of Willapa […]
Lost paradise worlds beneath the Earth’s oceans including those around the Britain are being “systemically destroyed” by climate change and over fishing before they can even be properly explored, claim scientists. By Richard Alleyne, Science Correspondent in San DiegoPublished: 1:56PM GMT 18 Feb 2010 The amazingly colourful undersea oases of life, some more than a […]
By Robin McKie, science editorThe Observer, Sunday 21 February 2010 Huge vents covering the sea-floor – among the strangest and most spectacular sights in nature – pour carbon dioxide and other gases into the deep waters of the oceans. Last week, as researchers reported that they had now discovered more than 50,000 underwater volcanic springs, […]
Press release issued 14 February 2010 A new model, capable of assessing the rate at which the oceans are acidifying, suggests that changes in the carbonate chemistry of the deep ocean may exceed anything seen in the past 65 million years. The model also predicts much higher rates of environmental change at the ocean’s surface […]
By Staff WritersBirmingham AL (SPX) Feb 05, 2010 The increasing acidity of the world’s oceans – and that acidity’s growing threat to marine species – are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment, says world-renowned Antarctic marine biologist Jim McClintock, Ph.D., professor […]
BIRMINGHAM, Ala. – The increasing acidity of the world’s oceans – and that acidity’s growing threat to marine species – are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment, says world-renowned Antarctic marine biologist Jim McClintock, Ph.D., professor in the University of Alabama at […]
A sweeping 15-year study of pH levels in the Pacific Ocean confirmed that upper reaches of the sea are becoming increasingly more acidic. By Sandi Doughton, Seattle Times science reporter The most extensive survey of pH levels in the Pacific Ocean confirms what spot measurements have suggested: From Hawaii to Alaska, the upper reaches of […]
Iron-poor oceans may cause populations of phytoplankton — a critical base of the marine food chain — to decline. By Jessica Marshall | Thu Jan 14, 2010 09:55 AM ET Rising acid levels in the world’s oceans appear to be robbing the tiny animals that form the bedrock of the marine food web of a […]
An extended time series of the regional mean aragonite saturation state for the Greater Caribbean Region derived using the NOAA extended reconstructed SST (ER SST V3b; red curve) with the Experimental Ocean Acidification Product Suite v0.3 values derived from satellite SST overlaid (blue curve). The global mean (green curve) is estimated from the representative SST […]
