The world's oceans are becoming noisier thanks to pollution, with potentially harmful effects for whales, dolphins and other marine life, US scientists said in a study published Sunday. http://www.physorg.com/news180548031.html Space & Earth Sun, 20 Dec 2009 16:17:17 EST news180548031 The northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by up to one-third the length of a football field annually because of a "triple whammy" of declining sea ice, warming seawater and increased wave activity, according to new study led by the University of Colorado at Boulder. http://www.physorg.com/news180039688.html Space & Earth Mon, 14 Dec 2009 20:50:09 EST news180039688 (PhysOrg.com) -- As the world`s seawater becomes more acidic due to rising atmospheric carbon dioxide, some shelled marine creatures may actually become bigger and stronger, according to a new study. http://www.physorg.com/news178904818.html Space & Earth Tue, 01 Dec 2009 15:51:26 EST news178904818 Since 1985, seawater temperature in Kuwait Bay, northern Arabian Gulf, has increased on average 0.6°C per decade. This is about three times faster than the global average rate reported by the Intergovernmental Panel on Climate Change (IPCC). Differences are due to regional and local effects. Increased temperatures are having profound effects on key habitats and on power generation the Arabian Gulf. http://www.physorg.com/news178809198.html Space & Earth Mon, 30 Nov 2009 13:30:01 EST news178809198 (PhysOrg.com) -- It sounds like a classic horror story -- eyeless, mouthless worms lurk in the dark, settling onto dead animals and sending out green "roots" to devour their bones. In fact, such worms do exist in the deep sea. They were first discovered in 2002 by researchers at the Monterey Bay Aquarium Research Institute, who were using a robot submarine to explore Monterey Canyon. But that wasn't the end of the story. After "planting" several dead whales on the seafloor, a team of biologists recently announced that as many as 15 different species of boneworms may live in Monterey Bay alone. http://www.physorg.com/news177100746.html Biology Tue, 10 Nov 2009 18:39:38 EST news177100746 A team of oceanographers and astrobiologists is currently exploring one of the deepest points in the Caribbean Sea.

Perpetually covered by more than 60 feet of ice, the brine below -- water that is five to seven times more salty than seawater -- has been found to be home to cryobiological microbes some 2,800 years old which were revived after a gradual thaw. http://www.physorg.com/news172171624.html Space & Earth Mon, 14 Sep 2009 18:28:04 EST news172171624 New research involving scientists from the National Oceanography Centre, Southampton (NOCS) highlights the potential utility of iron isotopes for addressing important questions in ocean science. The findings are published in the August edition of the journal Geology. http://www.physorg.com/news168252822.html Space & Earth Fri, 31 Jul 2009 10:10:03 EST news168252822 This summer, one of the world's leading ocean science bodies, the United Nations Educational, Scientific and Cultural Organization's (UNESCO's) and Intergovernmental Oceanographic Commission (IOC) adopted the new international thermodynamic equation of state for seawater called TEOS-10. A complex, dynamic mixture of dissolved minerals, salts, and organic material, seawater has historically presented difficulties in terms of determining its physical chemical properties. http://www.physorg.com/news168246156.html Space & Earth Fri, 31 Jul 2009 09:30:57 EST news168246156 The world's peak ocean science body has adopted a new definition of seawater developed by Australian, German and US scientists to make climate projections more accurate. http://www.physorg.com/news167319012.html Space & Earth Mon, 20 Jul 2009 15:00:01 EST news167319012 The world's peak ocean science body has adopted a new definition of seawater developed by Australian, German and US scientists to make climate projections more accurate. http://www.physorg.com/news166196667.html Space & Earth Tue, 07 Jul 2009 14:46:07 EST news166196667 The collapse began rather unspectacularly. In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, Washington's shellfish growers largely shrugged it off. http://www.physorg.com/news164811245.html Space & Earth Sun, 21 Jun 2009 15:30:01 EST news164811245 North Carolina State University engineers have created a non-toxic "wrinkled" coating for use on ship hulls that resisted buildup of troublesome barnacles during 18 months of seawater tests, a finding that could ultimately save boat owners millions of dollars in cleaning and fuel costs. http://www.physorg.com/news162723992.html Chemistry Thu, 28 May 2009 10:07:38 EST news162723992 Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. A study to be published online March 13, 2009 in Geophysical Research Letters by researchers at the Carnegie Institution and the Hebrew University of Jerusalem warns that if carbon dioxide reaches double pre-industrial levels, coral reefs can be expected to not just stop growing, but also to begin dissolving all over the world. http://www.physorg.com/news155848204.html Space & Earth Mon, 09 Mar 2009 20:11:04 EST news155848204 (PhysOrg.com) -- While working on her doctorate, Anette Bauer Ellingsen discovered potentially disease-causing vibrios (Vibrio cholerae, V. parahaemolyticus and V. vulnificus) in Norwegian seafood and inshore seawater. http://www.physorg.com/news154708942.html Space & Earth Tue, 24 Feb 2009 14:42:59 EST news154708942 (PhysOrg.com) -- Two miles below the surface of the Sargasso Sea lies a depression in the Earth`s crust filled with sediment and, scientists believe, teeming with life - exotic, microscopic, and very likely never before seen by human eyes. http://www.physorg.com/news153678729.html Space & Earth Thu, 12 Feb 2009 16:32:40 EST news153678729 The research focused on the bacterium Nautilia profundicola, a microbe that survives near deep-sea hydrothermal vents. Photosynthesis cannot occur in this dark environment, where hot, toxic fluids oozing from below the seafloor combine with cold seawater at very high pressures. http://www.physorg.com/news153145518.html Biology Fri, 06 Feb 2009 12:25:58 EST news153145518 Seawater is a complex, dynamic mixture of dissolved minerals, salts, and organic materials that despite scientists best efforts, presents difficulties in measuring its potential to contain and disperse energy. Like the water itself, the calculations scientists employ to measure seawater are fluid, undergoing significant revisions and clarifications over the years as research techniques and instrumentation continues to evolve. http://www.physorg.com/news153061487.html Space & Earth Thu, 05 Feb 2009 13:06:53 EST news153061487 (PhysOrg.com) -- Even Charles Darwin was puzzled by the apparently sudden appearance in the fossil record of a great variety of multicellular creatures - a rapid blossoming known as the Cambrian explosion. Since then, the origin of animals was found to extend back earlier, through a period known as the Ediacarian. Now, evidence found by researchers at MIT, UC Riverside and other institutions shows that the first complex life forms may in fact have appeared much earlier still. http://www.physorg.com/news152976776.html Biology Wed, 04 Feb 2009 13:33:27 EST news152976776 A new research study at the University of Delaware seeks to determine why Vibrio parahaemolyticus, a microorganism that lives in seawater and is related to the bacterium that causes cholera, is expanding its range and virulence. http://www.physorg.com/news151765070.html Biology Wed, 21 Jan 2009 12:58:32 EST news151765070 Tropical oceans are known as the deserts of the sea. And yet this unlikely environment is the very place where the rich and fertile coral reef grows. Dutch researcher Jasper de Goeij investigated how caves in the coral reef ensure the reef's continued existence. Although sponges in these coral caves take up a lot of dissolved organic material, they scarcely grow. However, they do discard a lot of cells that in turn provide food for the organisms on the reef. http://www.physorg.com/news151074780.html Biology Tue, 13 Jan 2009 13:13:00 EST news151074780
