A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S.Clean water for drinking, washing and industrial uses is a scarce resource in some parts of the world. Its availability in the future will be even more problematic. Many locations already desalinate water using either a reverse osmosis process -- one that pushes water under high pressure through...

This summer, one of the world's leading ocean science bodies, the United Nations Educational, Scientific and Cultural Organization's (UNESCO's) and Intergovernmental Oceanographic Commission (IOC) adopted the new international thermodynamic equation of state for seawater called TEOS-10. A complex, dynamic mixture of dissolved minerals, salts, and organic material, seawater has historically presented difficulties in terms of determining its physical chemical properties.For 30 years, climate...

The world's peak ocean science body has adopted a new definition of seawater developed by Australian, German and US scientists to make climate projections more accurate. In Paris late last month the General Assembly of UNESCO's Intergovernmental Oceanographic Commission (IOC) accepted the case for the introduction of a new international thermodynamic description of seawater, cast in terms of a new salinity variable called Absolute Salinity.

Most people consume far too much salt, and a University of Iowa researcher has discovered one potential reason we crave it: it might put us in a better mood.UI psychologist Kim Johnson and colleagues found in their research that when rats are deficient in sodium chloride, common table salt, they shy away from activities they normally enjoy, like drinking a sugary substance or pressing a bar that stimulates a pleasant sensation in their brains."Things that normally would be pleasurable for...

A German study suggests human water consumption is causing an alarming drop in Dead Sea water levels, with serious environmental consequences. Shahrazad Abu Ghazleh and colleagues at the University of Technology in Darmstadt, Germany, said the lower water levels in the Dead Sea -- the deepest point on Earth -- can impact the area's ability to generate electricity and produce fresh water by desalinization. The researchers said normally the water levels of closed lakes such as the Dead Sea...

Proposed new international 'equation of state' employs absolute over practical salinity to redefine thermodynamic equation of seawater after 30 years Seawater is a complex, dynamic mixture of dissolved minerals, salts, and organic materials that despite scientists best efforts, presents difficulties in measuring its potential to contain and disperse energy. Like the water itself, the calculations scientists employ to measure seawater are fluid, undergoing significant revisions and...

Scientists have learned that fish poop may be beneficial to maintaining the delicate balance of the Earth's oceans. Using computer models, Rod W. Wilson, of the University of Exeter in England, and colleagues from the US, Canada and England discovered that bony fish excrete a crucial amount of inorganic carbon that works to maintain the oceans' ph balance. Using computer models, researchers estimated that bony fish produce between 812 million and 2,050 million tons of valuable inorganic...

A $4.4 billion canal that would stretch from the Red Sea to the Dead Sea would provide an abundance of power and fresh water, Jordanian officials say. The proposed canal also would keep the Dead Sea from drying up and disappearing within 50 years, said Adnan Zoubi, a spokesman for the Jordanian water ministry. The plan calls for a 110-mile long canal to channel several million tons of seawater into the Dead Sea each day, The Daily Telegraph reported Friday. The Dead Sea sits about 1,300 feet...

A new definition of seawater could boost the accuracy of projections for oceans and climate, scientists said. Oceans shift heat from the equator to the poles, regulating the planet's weather. Changes in salinity and temperature are major forces driving global currents as well as circulation patterns from the surface to the seabed. For scientists to figure out how oceans affect climate and how that interaction could change due to global warming, they must first understand exactly how much heat...

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...
