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, […]
Just 2 °C more and reefs stop producing a cloud-seeding gas, which could leave corals hotter still and rainforests drier Rising ocean temperatures might leave coral reefs in seriously hot water – without clouds for protection. Five years ago Graham Jones and his team at Southern Cross University in Lismore, New South Wales, Australia, demonstrated […]
By Staff WritersMiami (AFP) Feb 15, 2010 Miami (AFP) Feb 15, 2010 – The polar snap enveloping much of the United States in record cold has been killing off coral reefs in the normally balmy warm waters off the Florida Keys, experts said Monday. The unusually chilly weather so far this year has seen sea […]
By CORNELIA DEANPublished: May 15, 2007 Scientists have known for years that when fishing trawlers drag nets and gear across the ocean bottom they trap or kill almost all the fish, mollusks and other creatures they encounter. And the dragging destroys underwater features like reefs, turning the bottom to mud. Now, scientists have used satellite […]
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 […]
The world’s most miserable-looking fish is in danger of becoming extinct, according to scientists. By Andrew HoughPublished: 7:30AM GMT 26 Jan 2010 Scientists fear the blobfish, which can grow up to 12 inches, is in danger of being wiped out by over-fishing in its south eastern Australian habitat. The fish, which lives at depths of […]
Human expansion is wiping out species at about 1,000 times the “natural” or “background” rate and something must be done to slow the decline, according to the United Nations. The UN will launch the International Year of Biodiversity today, warning that the on-going loss of species around the globe will seriously affect the future of […]
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 […]
Using climatological salinities (World Ocean Atlas available from NOAA NODC at http://www.nodc.noaa.gov) and NOAA SSTOI, we extended this approach to model fields back through 1988 (Figure 2b), revealing regionally averaged Ωar values declining at a rate of about 3% per decade amid considerable seasonal variability. These values are consistent with in situ measurements obtained at […]
