Scientists have long known that seawater contains small concentrations of valuable metals, but a technologically feasible extraction method has remained elusive. The University of Chicago’s Carter Abney, a graduate student in chemistry, has been developing materials called metal-organic frameworks to help address the problem. (more…)
*Projections for the future still loom large*
The seas are creeping higher as the planet warms. But how high could they go?
Projections for the year 2100 range from inches to several feet, or even more.
The sub-tropical islands of Bermuda and the Bahamas are two seemingly unlikely places scientists have gone looking for answers. (more…)
Levels of radioactive iodine in seawater just offshore of the embattled Fukushima Daiichi nuclear plant spiked to more than 1,250 times higher than normal, Japan’s nuclear and industrial safety agency said Saturday.
Samples taken Friday morning from a monitoring station 330 meters off the coast were significantly higher than results from the previous morning, when the level was 104 times above normal, according to CNN International. (more…)
A North Carolina State University researcher is part of a team which has found that methane from “cold seeps” – undersea areas where fluids bubble up through sediments at the bottom of the ocean – could be contributing to the oceans’ increasing acidity and stressing already delicate undersea ecosystems.
Oceanic microorganisms and bacteria survive by consuming dissolved organic carbon, or DOC. A byproduct of this consumption is CO2 – carbon dioxide – which, in large enough concentrations, makes seawater more acidic. (more…)
Contrary to some previous, highly publicized, reports, ocean acidification is not likely to worsen the hearing of whales and other animals, according to a Woods Hole Oceanographic Institution (WHOI) scientist who studies sound propagation in the ocean. (more…)
