Oxygen Depletion In Baltic Sea Is 10 Times Worse Than A Hundred Years Ago
2014-04-01 14:34:17

Aarhus University This news release is available in German. After several years of discussions, researchers from Aarhus University (Denmark), Lund University (Sweden) and Stockholm University (Sweden) have determined that nutrients from the land are the main cause of widespread areas of oxygen depletion. The results were published on 31 March in the prestigious American journal Proceedings of the National Academy of Sciences. Nutrients are the villain The deepest areas of the...

National Snow and Ice Data Center Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage — a direct shipping route from Europe to Asia across the Arctic Ocean — to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and University...

Climate Change Slowing Down Deep Ocean Conveyor Belt
2014-03-24 08:42:04

Katherine Unger Baillie, University of Pennsylvania Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new study by the University of Pennsylvania’s Irina Marinov and Raffaele Bernardello and colleagues from McGill University has found that recent climate change may be acting to slow down one of these conveyer belts, with potentially serious consequences for the future of the planet’s climate....

emission and transport of dust and other important aerosols to the Southern Ocean on Dec. 30, 2006
2014-03-22 06:56:44

April Flowers for redOrbit.com - Your Universe Online In a region of the Southern Ocean, iron fertilization caused plankton to thrive during the last ice age, according to a new study from Princeton University and the Swiss Federal Institute of Technology in Zurich. The findings, published in Science, confirm a longstanding theory that wind-borne dust carried iron to this region of the Antarctic. This iron dust drove plankton growth and eventually led to the removal of carbon dioxide...

World Water Day Highlights Relationship Between Water And Energy
2014-03-21 08:39:35

Lawrence LeBlond for redOrbit.com - Your Universe Online It’s the United Nations’ annual World Water Day and this year’s theme is the relationships between water and energy, with the UN predicting that the global population will need at least 40 percent more water and 50 percent more energy by 2030. "Water and energy are among the world's most pre-eminent challenges. This year's focus of World Water Day brings these issues to the attention of the world," said Michel Jarraud,...

Plankton Make Scents For A Cooler Planet And Seabirds
2014-03-21 08:22:49

University of California, Davis The top predators of the Southern Ocean, far-ranging seabirds, are tied both to the health of the ocean ecosystem and to global climate regulation through a mutual relationship with phytoplankton, according to newly published work from the University of California, Davis. When phytoplankton are eaten by grazing crustaceans called krill, they release a chemical signal that calls in krill-eating birds. At the same time, this chemical signal — dimethyl...

Sea Snakes Need Fresh Water For Drinking
2014-03-20 15:30:59

Cindy Spence, University of Florida Although they spend their lives surrounded by water, sea snakes dehydrate for months at a time, waiting to quench their thirst with fresh water from rainfall, a University of Florida biologist has found. The finding contradicts the accepted belief that marine vertebrates have evolved to use salt water to meet their water requirements, said professor Harvey Lillywhite, whose research appears [Wednesday/today] in the Proceedings of the Royal Society B,...

Wetland
2013-04-19 18:19:23

A wetland is an area of land that is saturated with water, either permanently or seasonally, such that it takes on the traits of a distinct ecosystem. First and foremost, the factor that distinguishes the wetlands from other land forms or water bodies is the unique vegetation that has adapted to its characteristic soil conditions. The wetland consists mostly of hydric soil, which is supportive of aquatic plants. The water that is found in wetlands can be saltwater, brackish, or freshwater....

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Little tunny, Euthynnus alletteratus
2013-03-28 14:07:39

The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...

Water Pollution
2013-03-25 12:43:15

Water pollution is the contamination of bodies of water including rivers, oceans, lakes, aquifers and groundwater. Water pollution is when pollutants are discharged directly or indirectly into a body of water without adequate treatment to remove harmful compounds. Water pollution affects the plants and organisms that reside in these bodies of water. In almost all of the cases the effect is damaging not only to individual species and populations, but to the natural biological communities as...

Ocean Analysis for November 17, 2012
2012-11-17 08:24:58

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...
