• Advocates Renew Calls for Large-Scale Restoration of La.'s Coastal Wetlands

    Four years after Hurricanes Katrina and Rita ravaged the Louisiana coast, federal and state officials are making little progress in restoring the state's storm-buffering coastal wetlands. Now, restoration advocates and scientists are increasing calls for a solution that takes advantage of the Mississippi River's natural land-building power by reconnecting the sediment-laden river to its sediment-starved delta. >> Read the Full Article
  • Arctic Fisheries Get a New Plan – The Fish Would Approve

    Global Warming is opening up new areas for fishing. We don't know that much about the ecosystems in these areas since they have been under ice until recently. Yesterday, U.S. Secretary of Commerce Gary Locke approved a plan to prohibit the expansion of commercial fishing in federal Arctic waters until researchers gather sufficient information on fish and the Arctic marine environment to try to prevent adverse impacts of commercial harvesting activity on the ecosystem. >> Read the Full Article
  • Mercury Persists in Fish in Many Parts of US

    The U.S. Geological Survey released a study that showed mercury contamination in every fish sampled in 291 streams across the country. The work was part of the National Water-Quality Assessment Program (NAWQA) which provides an understanding of water-quality conditions such as whether conditions are getting better or worse over time and how natural features and human activities affect those conditions. Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis. >> Read the Full Article
  • Not from My Back Yard? Homes Pollute

    They say there's no place like home. But scientists are reporting some unsettling news about homes in the residential areas of California. The typical house there — and probably elsewhere in the country — is an alarming and probably underestimated source of water pollution, according to a new study reported today at the 238th National Meeting of the American Chemical Society. >> Read the Full Article
  • The Asian Clams of Lake Tahoe are getting TOO comfortable!

    The population of the small coffee-colored Asian clams has soared in the southeast portion of the lake, threatening to hog food sources and excrete nutrients that foster algae growth, according to an annual Lake Tahoe report by UC Davis researchers. >> Read the Full Article
  • No Matter How Well You Model it, Humans are to Blame

    New research appearing in the online issue of the Proceedings of the U.S. National Academy of Sciences, Lawrence Livermore National Laboratory scientists and a group of international researchers found that model quality does not affect the ability to identify human effects on atmospheric water vapor. >> Read the Full Article
  • Do Phosphate Oridnances Make a Difference?

    Phosphorus levels in the Huron River dropped an average of 28 percent after Ann Arbor adopted an ordinance in 2006 that curtailed the use of phosphorus on lawns. >> Read the Full Article
  • Record Month for Renewable Energy in the U.S.

    The latest Electric Power Monthly Report released by the Energy Information Administration (EIA) shows net U.S. electrical generation from renewable sources (biomass, geothermal, solar, hydro, and wind) reached an all-time high in May of 2009, comprising 13% of the total electrical generation for the month. >> Read the Full Article
  • Was Shark in JAWS real after all?

    Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems. >> Read the Full Article
  • Surprise, Sea Temperatures in July Hottest on Record!

    The Earth's oceans were the warmest ever this July, according to a study released by the National Oceanic and Atmospheric Administration yesterday. The planet's ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA's National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880. >> Read the Full Article
