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 Reducing jet lag is the aim of a new mathematical methodology and software program developed by researchers at Brigham and Women's Hospital and the University of Michigan. http://www.physorg.com/news164554488.html Other Sciences Thu, 18 Jun 2009 15:30:02 EST news164554488 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 Climate change is altering North American winter bird communities in ways that models currently favored by ecologists fail to predict. http://www.physorg.com/news163822271.html Biology Wed, 10 Jun 2009 03:13:42 EST news163822271 (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 NASA's Kepler mission has taken its first images of the star-rich sky where it will soon begin hunting for planets like Earth. http://www.physorg.com/news159110447.html Space & Earth Thu, 16 Apr 2009 14:21:49 EST news159110447 (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 deployment of military personnel to active war zones, which involves issues of separation, time away from home, and eventual reunion, increases the vulnerability of their families, The heavy reliance on National Guard and Reservists and the downsizing of traditional installations means that military families are increasingly likely to live in local communities rather than on military installations. This new context of military service ushers in new challenges for providing support to military families. http://www.physorg.com/news158405217.html Medicine & Health Wed, 08 Apr 2009 10:27:17 EST news158405217 (AP) -- Scientists sailed Thursday to inspect an undersea volcano that has been erupting for days near Tonga - shooting smoke, steam and ash thousands of feet (meters) into the sky above the South Pacific ocean. http://www.physorg.com/news156663985.html Space & Earth Thu, 19 Mar 2009 06:47:14 EST news156663985 In a startling result, a new study published by the scientific journal Conservation Biology found that more than 80 percent of the world's major armed conflicts from 1950-2000 occurred in regions identified as the most biologically diverse and threatened places on Earth. http://www.physorg.com/news154350232.html Biology Fri, 20 Feb 2009 11:05:08 EST news154350232 In the first systematic analysis of threats to the biodiversity of the world's mediterranean-climate regions, scientists at The Nature Conservancy and UC Davis report that these conservation hotspots are facing significant and increasing pressure. The study, which appears in this week's edition of the journal Diversity and Distributions, is part of a global conservation assessment of the rare mediterranean biome. http://www.physorg.com/news154097352.html Space & Earth Tue, 17 Feb 2009 12:49:46 EST news154097352 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 New hazard maps for communities from San Jose to Palo Alto in Northern California delineate the probability of earthquake-induced liquefaction, based on three scenarios: a magnitude 7.8 on the San Andreas Fault comparable to the 1906 event, a magnitude 6.7 on the Hayward Fault comparable to the 1868 event, and a magnitude 6.9 on the Calavaras Calaveras Fault. http://www.physorg.com/news152273940.html Space & Earth Tue, 27 Jan 2009 10:19:32 EST news152273940 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 (PhysOrg.com) -- When volcanoes erupt, pinpointing the regions at high risk for lethal hazards and deciding whether or not to evacuate a resistant population comprise the most difficult problems faced by hazards managers. Now a team of volcanologists has a program that maps potential problem areas quickly, taking much of the guesswork out of decision making and evacuations. http://www.physorg.com/news151773037.html Space & Earth Wed, 21 Jan 2009 15:11:08 EST news151773037 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 (PhysOrg.com) -- Conservation zones are in the wrong place to protect vulnerable coral reefs from the effects of global warming, an international team of scientists warned today. http://www.physorg.com/news138978035.html Space & Earth Tue, 26 Aug 2008 14:00:35 EST news138978035 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
