After the biggest mass extinction in Earth’s history – 250 million years ago – algae and bacteria in the ocean rebounded so fast that they consumed virtually all the oxygen in the sea, slowing the recovery of the rest of marine animals for several million years. BY LOUIS BERGERONMarch 24, 2011 A mass extinction is […]

WASHINGTON (AFP) – Climate change could increase exposure to water-borne diseases originating in oceans, lakes and coastal ecosystems, and the impact could be felt within 10 years, US scientists told a conference in Washington on Saturday. Several studies have shown that shifts brought about by climate change make ocean and freshwater environments more susceptible to […]
Paper has implications for oxygen depletion, provides photographic evidence of plumes By Sam Fahmy, sfahmy@uga.eduFeb 13, 2011, 13:04 Athens, Ga. – A new University of Georgia study that is the first to examine comprehensively the magnitude of hydrocarbon gases released during the Deepwater Horizon Gulf of Mexico oil discharge has found that up to 500,000 […]
By Kate SpinnerThursday, February 3, 2011 at 1:00 a.m. From a distance the toxic goo looks like oil, but up close it smells like rotten eggs and wiggles like jelly. Scientists have no idea what it is or how it wound up in the northern Gulf of Mexico, near Perdido Pass. Just off the Florida […]
By Deborah Zabarenko, Environment Correspondent; Editing by Peter CooneyThu Jan 6, 2011 4:17pm EST WASHINGTON (Reuters) – Bacteria ate nearly all the potentially climate-warming methane that spewed from BP’s broken wellhead in the Gulf of Mexico last year, scientists reported on Thursday. Nearly 200,000 tons of methane — more than any other single hydrocarbon emitted […]
Most of the Chesapeake Bay fails to meet dissolved oxygen goals in the Summer. From 2007 to 2009, only 12 percent of the Chesapeake Bay had sufficient levels of dissolved oxygen in the summer. The National Oceanic and Atmospheric Administration (NOAA) describes the Chesapeake Bay as “highly eutrophic,” meaning that it is highly susceptible to […]
December 22, 2010 — Billfish and tuna, important commercial and recreational fish species, may be more vulnerable to fishing pressure because of shrinking habitat according to a new study published by scientists from NOAA, The Billfish Foundation, and University of Miami Rosenstiel School of Marine and Atmospheric Science. An expanding zone of low oxygen, known […]
Gothenburg, Sweden (SPX) Dec 09, 2010 – Continued eutrophication of the Baltic Sea, combined with an ever thinner ozone layer, is favouring the toxic cyanobacterium Nodularia spumigena, reveals research from the University of Gothenburg, Sweden. “There are several species of cyanobacteria, or blue-green algae, that can form surface blooms in the Baltic Sea,” explains Malin […]
CONTACT: Contact EWG Public Affairs 202-667-698212-07-2010 WASHINGTON – For more than thirty years, contamination from high-intensity farming has been adding to the pollution that fouls Chesapeake Bay, one of America’s most storied waterways. A new report from the Environmental Working Group (EWG) shows that weakly regulated agricultural practices in the six states of the Chesapeake […]
