Norman, Okla.–Biodiversity in freshwater systems is impacted as much or more by environmental change than tropical rain forests, according to University of Oklahoma Professor Caryn Vaughn, who serves as director of the Oklahoma Biological Survey. “When we think about species becoming extinct, we don’t necessarily think of the common species in freshwater systems, many of […]
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 […]
By DEBRA JOPSONJanuary 12, 2010 They are the farmers who play god to the oysters which feed Sydney. In Tuross Lake there are no longer natural tides since the big dry closed the nearby river entrance to the sea last year, so Graeme Campbell and his son Daniel replicate the flow which keeps their stock […]
Thousands of dead octopuses have washed up on a beach in northern Portugal, in what is being called an environmental disaster. They cover a 5-mile stretch of Vila Nova de Gaia beach – no reason has yet been found for their appearance. The authorities have warned the public not to eat them. Thousands of dead […]
By 2050, ocean acidity could increase by 150 percent. This increase is 100 times faster than any change in acidity experienced in the marine environment over the last 20 million years. By Nanet Poulsen 14/12/2009 06:10 The secretariat of the Convention on Biological Diversity (CBD) released Monday a major study in collaboration with the UNEP […]
By Daniel Whitten Jeremy Brown, a fisherman from the Pacific Northwest, is pulling things from the ocean he says are so disturbing that he came to Washington to warn U.S. lawmakers about it. “This is not overfishing, this is something far larger,” said Brown, one of 10 people who met with lawmakers and legislative aides […]
By Idrak Abbasov PIRALLAHI ISLAND, Azerbaijan, November 24, 2009 (ENS) – The fishermen perched on the beached boats on the Azerbaijan coast watched Faiq Balayev as he threw out his net, drew it in and trudged back to the shore. They need not have bothered, since he had once again failed to catch any shrimps. […]
Greenhouse gas emissions from vehicles, power stations and industries far to the south are putting shellfish in the Arctic Ocean at risk, an international team reports in the Nov. 20 edition of the journal Science. Acidification may put “some species at risk,” the researchers said, saying this could have a major impact on the entire […]
Changes in surface ocean pH relative to pre-industrial values for different atmospheric CO2 stabilization levels, 380 ppm and 650 ppm plotted over existing shallow-water coral reef locations (shown as magenta dots). Results are obtained by adding model-predicted perturbations in geochemical fields to modern observations, except for the Arctic Ocean where results are model simulations only […]
Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University’s School of Marine and Atmospheric Sciences. In one of the first studies looking at the effect […]
