Category: carbon sequestration in ocean

Yesterday we ran a post on two UK stories that included one report, in the Guardian and prompted by a Nature-published study, on the fate of algae and other plankton that bloom in the sea when fertilized by iron. The gist is that a research team ran its test to a well-defined ocean eddy and were thus able to see what happens to the organic, carbon-rich material in the bloom in relative isolation from surrounding waters. They report that a large share of the blooms eventually sank deep, perhaps to sediments. Thus prospects increase that some atmospheric carbon can be diverted to the sea floor in a form that will stay there, relatively...
