A team of scientists, speaking today at the annual meeting of the American Association for the Advancement of Science, called for new awareness of the potential for antibiotic-resistant illnesses from the marine environment, and pointed to the marine realm as a source for possible cures of those threats. http://www.physorg.com/news153760926.html Space & Earth Fri, 13 Feb 2009 15:22:28 EST news153760926 (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 Over the last two decades, marine biologists have discovered lush forests of deep-sea corals and sponges growing on seamounts (underwater mountains) offshore of the California coast. It has generally been assumed that many of these animals live only on seamounts, and are found nowhere else. However, two new research papers show that most seamount animals can also be found in other deep-sea areas. Seamounts, however, do support particularly large, dense clusters of these animals. These findings may help coastal managers protect seamounts from damage by human activities. http://www.physorg.com/news153594680.html Biology Wed, 11 Feb 2009 17:12:03 EST news153594680 The economy isn't just squeezing the middle class on land, it's also affecting fish. http://www.physorg.com/news153494857.html Space & Earth Tue, 10 Feb 2009 13:28:06 EST news153494857 In the era of global warming, when many scientists say we are experiencing a human-caused mass extinction to rival the one that killed off the dinosaurs, one might think that the discovery of a host of new species would be cause for joy. Not entirely so, says Paul Ehrlich, co-author of an analysis of the 408 new mammalian species discovered since 1993. http://www.physorg.com/news153422411.html Biology Mon, 09 Feb 2009 17:22:30 EST news153422411 Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or - a surprising new study finds - float up from the sea floor. The discovery, published online Feb. 8 in Nature Geoscience, connects life at the surface to events occurring at extreme depths and pressures. http://www.physorg.com/news153323371.html Space & Earth Sun, 08 Feb 2009 13:50:12 EST news153323371 (PhysOrg.com) -- This artist's rendering shows a "family portrait" of Jason-1, Topex/Poseidon, and OSTM/Jason-2, all NASA satellites that collect data about sea surface heights around the world. Sea surface heights are one component helpful to hurricane forecasters, as higher seas indicate warmer waters (that power storms) while lower seas indicate cooler waters (such as those in La Nina events in the eastern Pacific). http://www.physorg.com/news153146272.html Space & Earth Fri, 06 Feb 2009 12:38:25 EST news153146272 In the journal Estuarine, Coastal and Shelf Science, University of Miami Rosenstiel School of Marine and Atmospheric Science Professor Dr. Peter Glynn, and 2008 Pew Fellow for Marine Conservation and Assistant Professor Dr. Andrew Baker, assess more than 25 years of data on reef ecosystems recovery from climate change-related episodes of coral bleaching. Coral bleaching - in which corals expel their symbiotic algal partners and turn pale or white - is one of the most visible impacts of climate change on marine ecosystems. Typically caused by higher-than-normal ocean temperatures, it can lead to widespread death of corals and is a major contributor to the rapid decline of coral reef ecosystems worldwide. http://www.physorg.com/news152883948.html Space & Earth Tue, 03 Feb 2009 11:46:21 EST news152883948 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 Imagine a massive international effort to combat global warming by reducing carbon dioxide - build up in the atmosphere. It involves gathering billions of tons of cornstalks, wheat straw, and other crop residue from farm fields, bailing it, shipping the material to seaports, and then burying it in the deep ocean. http://www.physorg.com/news152807537.html Space & Earth Mon, 02 Feb 2009 14:32:37 EST news152807537 Get ready to send the biology textbooks back to the printer. In a new paper published in Nature, Benjamin Van Mooy, a geochemist with the Woods Hole Oceanographic Institution (WHOI) and his colleagues report that microscopic plants growing in the Sargasso Sea have come up with a completely unexpected way of building their cells. http://www.physorg.com/news152804048.html Chemistry Mon, 02 Feb 2009 13:34:33 EST news152804048 Web visitors can now share the excitement of Census of Marine Life explorations as scientists uncover the mysteries of what lives below the surface of the global ocean. http://www.physorg.com/news152803130.html Space & Earth Mon, 02 Feb 2009 13:19:29 EST news152803130 In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle. The find strongly suggests that animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean. http://www.physorg.com/news152720213.html Other Sciences Sun, 01 Feb 2009 14:17:17 EST news152720213 An experiment to study the effects of naturally deposited iron in the Southern Ocean has filled in a key piece of the puzzle surrounding iron's role in locking atmospheric carbon dioxide (CO2) in the ocean. The research, conducted by an international team led by Raymond Pollard of the National Oceanography Centre, Southampton, and included Matthew Charette, a marine chemist at the Woods Hole Oceanographic Institution (WHOI), found that natural iron fertilization enhanced the export of carbon to the deep ocean. The research was published January 29, 2009, in the journal Nature. http://www.physorg.com/news152538900.html Space & Earth Fri, 30 Jan 2009 11:55:31 EST news152538900 Urgent action is needed to limit damages to marine ecosystems, including coral reefs and fisheries, due to increasing ocean acidity, according to 155 of the world`s scientific experts who will release the Monaco Declaration this Friday. http://www.physorg.com/news152527254.html Space & Earth Fri, 30 Jan 2009 08:41:24 EST news152527254 (PhysOrg.com) -- Making bales with 30 percent of global crop residues -- the stalks and such left after harvesting -- and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. http://www.physorg.com/news152384963.html Space & Earth Wed, 28 Jan 2009 17:10:06 EST news152384963 A possible solution to global warming may be further away than ever, according to a new report published in the prestigious scientific journal Nature this week. http://www.physorg.com/news152372775.html Space & Earth Wed, 28 Jan 2009 13:46:44 EST news152372775 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 In an upcoming issue of Proceedings of the National Academy of Sciences, Yale researchers used newly developed mathematical models to analyze huge amounts of data on physical characteristics such as temperature and salinity in different ocean habitats and metabolic activity in marine micro-organisms. http://www.physorg.com/news151854172.html Other Sciences Thu, 22 Jan 2009 13:43:36 EST news151854172 (PhysOrg.com) -- An important British seabird has been tracked for the first time using miniature positioning loggers. The results are giving a team led by Oxford University zoologists information that could help conserve wildlife around Britain`s shores. http://www.physorg.com/news151772504.html Biology Wed, 21 Jan 2009 15:02:11 EST news151772504 With its unique location along the western bank of the Hudson River, Stevens Institute of Technology provided a dramatic front row venue for the emergency landing and successful rescue of U.S. Airways Flight 1549. http://www.physorg.com/news151763167.html Space & Earth Wed, 21 Jan 2009 12:26:43 EST news151763167 Are there really plenty of fish in the sea? University of British Columbia fisheries researcher Villy Christensen gives the first-ever estimate of total fish biomass in our oceans: Two billion tonnes. http://www.physorg.com/news151251277.html Space & Earth Thu, 15 Jan 2009 14:14:37 EST news151251277 Using a 218-year-long temperature record from a Bermuda brain coral, researchers at the Woods Hole Oceanographic Institution (WHOI) have created the first marine-based reconstruction showing the long-term behavior of one of the most important drivers of climate fluctuations in the North Atlantic. http://www.physorg.com/news151068670.html Space & Earth Tue, 13 Jan 2009 11:31:10 EST news151068670 (PhysOrg.com) -- Tomorrow, beach-goers will get a glimpse of what our coastlines may look like in 50 years, when New South Wales and South East Queensland experience the highest daytime ‘king tides` forecast for 2009. http://www.physorg.com/news150998525.html Space & Earth Mon, 12 Jan 2009 16:02:05 EST news150998525 (PhysOrg.com) -- The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726 Concern about increasing ocean acidification has often focused on its potential effects on coral reefs, but broader disruptions of biological processes in the oceans may be more significant, according to Donald Potts, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, and an expert in coral reef ecology and marine biodiversity. http://www.physorg.com/news148756963.html Space & Earth Wed, 17 Dec 2008 17:22:43 EST news148756963 (PhysOrg.com) -- Researchers have discovered that the ocean's chemical makeup is less stable and more greatly affected by climate change than previously believed. The researchers report in the December 12, 2008 issue of Science that during a time of climate change 13 million years ago the chemical makeup of the oceans changed dramatically. The researchers warn that the chemical composition of the ocean today could be similarly affected by climate changes now underway - with potentially far-reaching consequences for marine ecosystems. http://www.physorg.com/news148227653.html Space & Earth Thu, 11 Dec 2008 14:20:53 EST news148227653 In the last few years there has been a growing number of documented cases in which large earthquakes set off unfelt tremors in earthquake faults hundreds, sometimes even thousands, of miles away. http://www.physorg.com/news148136737.html Space & Earth Wed, 10 Dec 2008 13:05:37 EST news148136737 Intensifying winds in the Southern Ocean have had little influence on the strength of the Southern Ocean circulation and therefore its ability to absorb carbon dioxide from the atmosphere, according to a study published in Nature Geoscience. http://www.physorg.com/news147955224.html Space & Earth Mon, 08 Dec 2008 10:40:24 EST news147955224 University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought.
