| Aquatic 'dead zones' contributing to climate change Thu, 11 Mar 2010 00:00:00 EST |
(University of Maryland Center for Environmental Science) The increased frequency and intensity of oxygen-deprived "dead zones" along the world's coasts can negatively impact environmental conditions in far more than local waters. In the March 12 edition of Science, UMCES oceanographer Dr. Lou Codispoti explains that the increased amount of nitrous oxide produced in hypoxic waters can elevate concentrations in the atmosphere, further exacerbating the impacts of global warming and contributing to ozone "holes" that increase our exposure to harmful UV radiation. |

| Barnacles prefer upwelling currents, enriching food chains in the Galapagos Tue, 02 Mar 2010 00:00:00 EST |
(Brown University) The barnacle, a key thread in the marine food web, was thought to be missing along rocky coasts dominated by upwelling. Now a research team headed by Brown University marine ecologist Jon Witman has found the opposite to be true: Barnacle populations thrive in vertical upwelling zones in moderately deep waters in the Galapagos Islands. The findings appear in Ecological Monographs. |
| Researchers issue outlook for a significant New England 'red tide' in 2010 Tue, 02 Mar 2010 00:00:00 EST |
(NOAA Headquarters) Scientists from the NOAA-funded Gulf of Maine Toxicity project issued an outlook for a significant regional bloom of a toxic alga that causes "red tides" in the spring and summer of this year, potentially threatening the New England shellfish industry. |
| Research team breaks the ice with new estimate of glacier melt Tue, 02 Mar 2010 00:00:00 EST |
(Northern Arizona University) The melting of glaciers is well documented, but when looking at the rate at which they have been retreating, a team of international researchers steps back and says not so fast. |
| 2010 Central Gulf of Mexico Hurricane Conference, Baton Rouge, March 16-17 Tue, 02 Mar 2010 00:00:00 EST |
(NOAA Headquarters) NOAA and Louisiana State University will host the first-ever Central Gulf of Mexico Hurricane Conference on March 16-17, 2010, in Baton Rouge, La. The meeting will bring together 300-500 experts and officials from all levels -- including federal and state emergency managers, local public safety personnel, forecasters, university officials -- to discuss key issues of concern prior to the June 1 start of the 2010 Atlantic hurricane season. |
