Researchers Count Thousands Of Fish Using A Glass Of Water
2014-01-16 15:08:16

University of Washington A mere glass full of water from Monterey Bay Aquarium's 1.2 million-gallon Open Sea tank, among the 10 largest aquariums in the world, is all scientists really needed to identify the Pacific Bluefin tuna, dolphinfish and most of the other 13,000 fish swimming there. Researchers also for the first time used DNA from water samples to discern which of the species were most plentiful in the tank. Being able to determine the relative abundance of fish species in a...

Increased Mercury Levels In Arctic Ice Found Pushing Into Sea Water
2014-01-16 10:15:32

Gerard LeBlond for redorbit.com - Your Universe Online Researchers Dr. Chris Moore and Dr. Daniel Obrist, from Nevada's Desert Research Institute, have recently discovered an increased level of mercury in Arctic sea ice. The study, published in the journal Nature, also found that the element is contaminating sea water below. The researchers claim that the air above large cracks found in the ice of the Arctic is mixing vigorously pushing mercury down to the exposed seawater. This process...

African Tiger Fish Eats Bird
2014-01-13 11:30:38

Brett Smith for redOrbit.com - Your Universe Online Stories of the African tiger fish preying on birds in mid-flight have been circulating for years and a research team from South Africa has finally captured evidence of this behavior, according to a new study in the Journal of Fish Biology. “The whole action of jumping and catching the swallow in flight happens so incredibly quickly that after we first saw it, it took all of us a while to really fully comprehend what we had just...

Elephant Shark DNA Decoded
2014-01-08 15:35:28

Ranjini Raghunath for redOrbit.com - Your Universe Online An international team of scientists has deciphered the genetic blueprint of the elephant shark - the oldest living animal in the cartilaginous fish family and the first to have its DNA decoded. Among fish, cartilaginous fish such as sharks and rays stand out because their skeleton is not made of bones. Their body is supported instead by cartilage, a flexible tissue that resembles muscle. Analysis of the elephant shark’s DNA...

Carbon Dioxide Emissions Keep Conch Snails From Escaping Predation
2014-01-07 13:18:57

Brett Smith for redOrbit.com - Your Universe Online New research from an international team of scientists has found that if more carbon dioxide makes its way into the ocean – conch snails will be more vulnerable to predation. Conch snails typically use a strong foot-like appendage to leap away from approaching predators. According to the team’s study, published in the Proceedings of the Royal Society B: Biological Sciences, when the snails are exposed to carbon dioxide levels...

Fluctuation 'adds insult to injury' for marine creatures A new Duke University-led study has documented dramatic, natural short-term increases in the acidity of a North Carolina estuary. "The natural short-term variability in acidity we observed over the course of one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms that are especially susceptible to changes in...

In a bold new partnership to enhance natural fertilizer production between the public and private sector, the Encina Wastewater Authority and Anaergia Inc have partnered up to bring a modern twist to an age old gardening and farming practice. Carlsbad, CA (PRWEB) December 31, 2013 Today, the Encina Wastewater Authority (EWA) announced a strategic alliance with Anaergia Inc. to produce and distribute a distilled version of PureGreen, a natural bio-solid based fertilizer produced for the...

Mangrove Forests Pushed North By Climate Change
2013-12-31 10:10:08

redOrbit Staff & Wire Reports - Your Universe Online Cold-sensitive mangrove forests have been expanding northward along Florida’s Atlantic coast for the last few decades due to extreme weather changes, ecologists reported this week in the Proceedings of the National Academy of Sciences. The findings, which are based on 28 years of satellite data, offer a new and unique view of the speed and scale on which changes in climate extremes have affected vital ecosystems, the researchers...

Cold-sensitive mangrove forests have expanded dramatically along Florida’s Atlantic Coast as the frequency of killing frosts has declined, according to a new study based on 28 years of satellite data from the University of Maryland and the Smithsonian Environmental Research Center in Edgewater, Maryland. College Park, Md (PRWEB) December 30, 2013 Cold-sensitive mangrove forests have expanded dramatically along Florida’s Atlantic Coast as the frequency of killing frosts has declined,...

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...
