Data suggest sewage upgrades working, farm runoff controls aren’t By Timothy B. Wheeler, The Baltimore Sun September 15, 2010 A new study shows some Chesapeake Bay rivers have gotten cleaner over the past three decades, while others are getting worse. The analysis, released Wednesday by the U.S. Geological Survey, suggests costly upgrades of sewage plants […]
By PAUL VOOSEN of GreenwireSeptember 17, 2010 Perhaps it should have been called the Gulf of Mexico gas spill. A vast majority of the natural gas that billowed out of BP PLC’s failed well in the Gulf this summer did not escape to the surface and atmosphere. Instead, the gas — including its main component, […]
By Bob Warren, The Times-PicayuneMonday, September 13, 2010, 3:42 PM Plaquemines Parish officials have asked state wildlife officials to investigate what they said is a massive fish kill at Bayou Chaland on the west side of the Mississippi River late Friday. Photographs the parish distributed of the area shows an enormous amount of dead fish […]
Climate change is likely to expand and intensify “dead zones,” areas where bottom water is depleted of dissolved oxygen because of nitrogen pollution, threatening living things. More spring runoff and warmer coastal waters will increase the seasonal reduction in oxygen resulting from excess nitrogen from agriculture. Coastal dead zones in places such as the northern […]
By Mark Schleifstein, The Times-PicayuneWednesday, September 08, 2010, 6:00 AM The biodegradation of oil in plumes within 60 miles of the failed BP Macondo oil well have caused levels of dissolved oxygen in deep water of the Gulf of Mexico to drop by as much as 20 percent, but no oxygen-void dead zones have been […]
NBC Philadelphia reports that tens of thousands of dead menhaden fish washed ashore Wednesday on a New Jersey beach along Delaware Bay. The incident is strikingly similar to an occurrence from Monday, when thousands of dead menhaden also washed ashore over 200 miles away in Fairhaven, MA (see video HERE). N.J. Department of Environmental Protection […]
By Mike Lee, UNION-TRIBUNEFriday, September 3, 2010 at 10:03 a.m. Dead zones increased dramatically in U.S. waters over the past 50 years, threatening ecosystems and fisheries nationwide, according to a sweeping report Friday by the federal Office of Science and Technology Policy. The multiagency assessment said that incidents of hypoxia — a condition in which […]
By Deborah Zabarenko, Environment CorrespondentTue Aug 24, 2010 5:25pm EDT WASHINGTON (Reuters) – A Manhattan-sized plume of oil spewed deep into the Gulf of Mexico by BP’s broken Macondo well has been consumed by a newly discovered fast-eating species of microbes, scientists reported on Tuesday. The micro-organisms were apparently stimulated by the massive oil spill […]
(American Geophysical Union) A new simulation of oil and methane leaked into the Gulf of Mexico suggests that deep hypoxic zones or “dead zones” could form near the source of the pollution. The research investigates five scenarios of oil and methane plumes at different depths and incorporates an estimated rate of flow from the Deepwater […]
SkyTruthWednesday, August 18, 2010 Scientists vehemently disagreed with the brief report issued by the federal government on August 4 that some interpreted as evidence that most of the oil spilled from BP’s Macondo well was … gone. Researchers at the University of Georgia issued their own report yesterday, claiming that nearly 80% of the oil […]
