Global Warming to Increase Ocean Upwelling, but Fisheries Impact Uncertain
CORVALLIS, Ore. - A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will cause major changes in marine biodiversity. Since upwelling of colder, nutrient-rich water is a driving force behind marine productivity, one possibility may be enhancement of some of the world's most important fisheries.
