Among the many changes in the ocean is the expansion of oxygen-deficient or oxygen minimum zones (OMZs), also known as dead zones, which affect the processes by which carbon is captured and sequestered on the seafloor and alter the microbial activities that impact the rate and magnitude of ocean carbon sequestration. Despite the importance of these effects, very little is known about the metabolism of OMZ microbes and how they respond to environmental changes. http://www.physorg.com/news175439852.html Space & Earth Thu, 22 Oct 2009 14:18:14 EST news175439852 Scientists in Pennsylvania report that boosting production of crops used to make biofuels could make a difficult task to shrink a vast, oxygen-depleted "dead zone" in the Gulf of Mexico more difficult. The zone, which reached the size of Massachusetts in 2008, forms in summer and threatens marine life and jobs in the region. Their study is scheduled for the Oct. 1 issue of ACS' semi-monthly journal Environmental Science & Technology. http://www.physorg.com/news172319226.html Space & Earth Wed, 16 Sep 2009 11:50:13 EST news172319226 NOAA-supported scientists, led by Nancy Rabalais, Ph.D., from the Louisiana Universities Marine Consortium (LUMCON), found the size of this year's Gulf of Mexico dead zone to be smaller than forecasted, measuring 3,000 square miles. However the dead zone, which is usually limited to water just above the sea floor, was severe where it did occur, extending closer to the water surface then in most years. http://www.physorg.com/news167720984.html Space & Earth Sat, 25 Jul 2009 06:10:13 EST news167720984 University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" could be one of the largest on record, continuing a decades-long trend that threatens the health of a half-billion-dollar fishery. http://www.physorg.com/news164546116.html Space & Earth Thu, 18 Jun 2009 12:18:29 EST news164546116 (PhysOrg.com) -- New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. http://www.physorg.com/news159200016.html Space & Earth Fri, 17 Apr 2009 15:15:09 EST news159200016 (AP) -- A clean water expert at Auburn University hopes a new project that enlists middle and high school students will help reduce farm runoff that is a growing pollution threat to the Gulf of Mexico. http://www.physorg.com/news158562652.html Space & Earth Fri, 10 Apr 2009 06:11:24 EST news158562652 The specter of an ocean floor littered with dead shellfish, rock fish, sea stars and other marine life off the Oregon coast spurred Mark Snyder, a climate change expert, to investigate whether California's coast faced a similar calamity. http://www.physorg.com/news152808201.html Space & Earth Mon, 02 Feb 2009 14:44:29 EST news152808201 Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. In shallow coastal regions, these zones can be caused by runoff of excess fertilizers from farming. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean by a factor of 10 or more. http://www.physorg.com/news152112555.html Space & Earth Sun, 25 Jan 2009 13:30:00 EST news152112555 Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted waters. http://www.physorg.com/news143209351.html Biology Tue, 14 Oct 2008 13:22:31 EST news143209351 A global study led by Professor Robert Diaz of the Virginia Institute of Marine Science, College of William and Mary, shows that the number of "dead zones" -areas of seafloor with too little oxygen for most marine life -has increased by a third between 1995 and 2007. http://www.physorg.com/news137940602.html Space & Earth Thu, 14 Aug 2008 13:50:02 EST news137940602 Record-setting "dead zones" in the Gulf of Mexico and Chesapeake Bay appear likely this summer, according to new forecasts from a University of Michigan researcher. http://www.physorg.com/news135264139.html Space & Earth Mon, 14 Jul 2008 14:22:19 EST news135264139 (PhysOrg.com) -- It's summertime and people are flocking to the coasts around the country. But when summer storms arrive, it's not only beach-goers who are affected; the rains can also have an impact on living creatures far below the ocean surface. http://www.physorg.com/news134996583.html Space & Earth Fri, 11 Jul 2008 12:03:03 EST news134996583
