BURNABY, British Columbia, March 10, 2014 /PRNewswire/ -- Rising demand for fresh water along with stringent regulations by governments to reduce untreated wastewater disposal are driving demand for water and wastewater treatment chemicals Water treatment is carried out to make water usable for water intensive industries and domestic drinking purposes. The process requires use of effective and efficient chemicals such as scale and corrosion inhibitors, coagulants and...

New Technique Developed To Allow Frequent Water Quality Monitoring For Suite of Pollutants
2014-03-05 12:03:13

North Carolina State University Researchers from North Carolina State University have developed a new technique that uses existing technology to allow researchers and natural resource managers to collect significantly more information on water quality to better inform policy decisions. “Right now, incomplete or infrequent water quality data can give people an inaccurate picture of what’s happening – and making decisions based on inaccurate data can be risky,” says Dr. François...

Adipose Fins Evolve Repeatedly In Teleost Fishes
2014-03-05 10:33:13

University of Chicago Though present in more than 6,000 living species of fish, the adipose fin, a small appendage that lies between the dorsal fin and tail, has no clear function and is thought to be vestigial. However, a new study analyzing their origins finds that these fins arose repeatedly and independently in multiple species. In addition, adipose fins appear to have repeatedly and independently evolved a skeleton, offering a glimpse into how new tissue types and structural...

Arctic Sea Ice Trends
2014-03-05 08:10:23

April Flowers for redOrbit.com - Your Universe Online According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years. Julienne Stroeve, Professor of Polar Observation and Modeling at UCL Earth Sciences, led the team in analyzing satellite data. The analysis, published in Geophysical Research Letters, revealed that the Arctic Ocean is absorbing even more of the sun’s energy in summer, leading to an even...

Reducing the size of the Lake Erie "dead zone" to acceptable levels will require cutting nutrient pollution nearly in half in coming decades, at a time when climate change is expected to make such reductions more difficult. That's one of the main conclusions of a comprehensive new study that documents recent trends in Lake Erie's health. It offers science-based guidance to policymakers seeking to reduce the size of toxic algae blooms and oxygen-starved regions called hypoxic zones, or dead...

Where Did All The Codfish Go?
2014-02-27 13:44:10

University of Hawai‘i at Mānoa The mega-decline in cod and other fisheries across the North Atlantic Ocean threatens the livelihood of fishermen and communities in New England and Atlantic Canada. One suspect in the disappearance of cod and other groundfish is the food source for their young: a planktonic copepod crustacean, no larger than a grain of rice. Recent changes in local copepod populations have co-occurred with declines in fisheries elsewhere, such as the collapse of the cod...

Toxic Algae Most Likely Cause Of Ancient Chilean Whale Strandings
2014-02-26 10:08:48

Brett Smith for redOrbit.com - Your Universe Online A site in the Atacama Desert of Northern Chile has become well known for its wealth of ancient marine mammal fossils, deposited there by a series of mass strandings. While the cause of whale or other mammal strandings that take place today can often be identified, the cause behind ancient strandings is much more difficult to pin down. According to a newly published report in the Proceedings of the Royal Society B, an international...

Hannah Hickey, University of Washington The phrase, 'Eat your vitamins,' applies to marine animals just like humans. Many vitamins, including B-12, are elusive in the ocean environment. University of Washington researchers used new tools to measure and track B-12 vitamins in the ocean. Once believed to be manufactured only by marine bacteria, the new results show that a whole different class of organism, archaea, can supply this essential vitamin. The results were presented Feb. 24 at...

Fate Of Fish Stocks In The Baltic Sea Determined By Salt Stratification
2014-02-19 15:39:07

GEOMAR Helmholtz Centre for Ocean Research Kiel Why management strategies must take into account regional conditions In the Baltic Sea, two cod stocks evolve independently. Also the juveniles of two economically important flatfish species, flounder and plaice, live there within limited space. This is possible due to the irregular distribution of water masses of different salinity in this inland sea. Scientists of GEOMAR Helmholtz Centre for Ocean Research Kiel and the Institute of...

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...
