Using Satellite Data To Monitor Wetlands
2013-07-23 13:36:55

ESA The use of satellite data to monitor wetlands for sustainable water management is growing. Following promising results from monitoring efforts in the Mediterranean, ESA is working with African partners to expand its GlobWetland project even further. In the heart of Jordan's eastern desert, an oasis of marshland and natural water collection makes up the Azraq wetland. The wetland and adjacent mudflat were recognized in 1977 as an important station for migratory birds by the Ramsar...

New Variability In Iron Supply To The Oceans With Climate Implications Discovered By Scientists
2013-07-19 09:44:51

National Oceanography Centre, Southampton (UK) The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction. Iron is key to the removal of carbon dioxide from the Earth's atmosphere as it promotes the growth of microscopic marine plants (phytoplankton), which mop up the greenhouse gas and lock it away in the ocean. A new study, led by researchers based at the...

Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of the organism's occurrences. Over 70 percent of the world's surface is covered by the oceans. Compared with terrestrial ecosystems, the animals and plant species of the oceans have been researched relatively little. Because of this, the knowledge base concerning the...

Crustacean Sand-dwellers Suffering Localized Extinctions In Southern California
2013-07-18 11:14:11

University of California - Santa Barbara Two types of small beach critters -- both cousins of the beloved, backyard roly-poly -- are suffering localized extinctions in Southern California at an alarming rate, says a new study by UC Santa Barbara scientists. As indicator species for beach biodiversity at large, their disappearance suggests a looming threat to similar sand-dwelling animals across the state and around the world. Led by David Hubbard and Jenifer Dugan of UCSB's Marine...

Fish Relatives Surprise Scientists
2013-07-18 04:53:01

Susan Bowen for redOrbit.com - Your Universe Online Scientists have used genetic data to create a comprehensive evolutionary family tree, or phylogeny, for "spiny-rayed fish," a category that encompasses about a third of all living vertebrate species. They were quite surprised to find out just who was related to whom in the fish world. The researchers, who published their findings in the Proceedings of the National Academy of Sciences looked at 10 genes in more than 500 fish species...

University of Adelaide marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2. The researchers have found a combined effect on kelp forests from nutrient pollution and higher CO2, which could have a devastating impact on Australia's marine ecosystems. "When we manipulated CO2 and nutrient levels in an experimental marine ecosystem we found the effect of both of them together...

Ancient Algal Bloom Mystery Solved
2013-07-15 15:05:24

Brett Smith for redOrbit.com - Your Universe Online An ancient bloom of life that occurred just after the last ice age isn't what it seemed at first, according to new research in the journal Nature Geoscience. Scientists had long believed that the bloom, which occurred around 14,000 years ago, was spurred by rising sea levels washing iron into the ocean. However, the new study suggested that a "perfect storm" of conditions allowed for the bloom to happen, and not simply the abundance of...

Phytoplankton Ocean Turbulence Social Mixers
2013-07-15 12:58:35

[Watch the video: Phytoplankton Social Mixers] Lee Rannals for redOrbit.com - Your Universe Online The motility of phytoplankton allows the tiny ocean plants to determine their fate in ocean turbulence, according to scientists at MIT and Oxford University. Researchers wrote in the journal Nature Communications that the individual vortices that make up ocean turbulence are like social mixers for phytoplankton. This social mixer brings similar cells into close proximity, helping to...

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...
