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,...

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...

Water Crisis Could Be Averted By Newly-Discovered Undersea Freshwater Reserves
2013-12-09 05:16:17

[ Watch the Video: Freshwater Reserves Found Underneath The Sea ] redOrbit Staff & Wire Reports - Your Universe Online A team of Australian researchers have reportedly located massive freshwater reserves trapped beneath the ocean floor – a discovery that could help delay or prevent a burgeoning global water crisis, according to research published Thursday in the journal Nature. Flinders University professor Vincent Post, a hydrogeologist specializing in coastal groundwater...

Anxiety In Fish Caused By Rising Ocean Acidification
2013-12-04 19:35:14

Scripps Institution of Oceanography, UC San Diego Study shows acidity levels projected by the end of the century results in behavioral changes that could impact feeding, fisheries A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish. A growing base of scientific evidence has shown that the absorption of human-produced carbon dioxide...

Chesapeake Bay Impact Crater Is Home To Oldest Seawater On Earth
2013-11-22 04:32:34

[ Watch the Video: Old Water Found In The New World ] redOrbit Staff & Wire Reports - Your Universe Online US Geological Survey (USGS) hydrologists drilling into the largest crater in the country have stumbled across an amazing discovery – the oldest body of seawater ever unearthed. The water, which according to Discovery News is at least 100 million years old, was found over one kilometer beneath Chesapeake Bay in Virginia. The seawater is believed to have come from the...

New Generation Of Micro Sensors Developed For Monitoring Ocean Acidification
2013-11-13 14:14:45

National Oceanography Centre, Southampton (UK) The first step in developing a cost-effective micro sensor for long-term monitoring of ocean acidification has been achieved by a team of scientists and engineers. The new technology, that will measure pH levels in seawater, was developed by engineers from the National Oceanography Centre, in close collaboration with oceanographers from University of Southampton Ocean and Earth Science, which is based at the center. The team successfully...

Receding Ice Exposes Seawater To Carbon Dioxide, Driving Ocean Acidification In The Arctic Ocean
2013-09-13 12:12:21

University of South Florida (USF Health) Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem. Ocean acidification is the process by which pH levels of seawater decrease due to greater amounts of carbon dioxide being absorbed by the oceans from the atmosphere....

New Technology Drinking Water From Sea Water
2013-06-27 15:52:53

[ Watch the Video: Desalting the Ocean ] Michael Harper for redOrbit.com - Your Universe Online Researchers at the University of Texas at Austin (UT) and the University of Marburg in Germany have created a simple and efficient way to desalinate ocean water. Once completed, the water can be used as drinking water or to irrigate crops. Current desalination methods take the salt from seawater using a membrane as a filter. The new method, called electrochemically mediated seawater...

New CO2 Removal Technique Produces Green Fuel, Offsets Ocean Acidification
2013-05-29 10:31:52

April Flowers for redOrbit.com - Your Universe Online A new technique to remove and store atmospheric carbon dioxide has been demonstrated by scientists at the Lawrence Livermore National Laboratory (LLNL). The new technique also generates carbon-negative hydrogen and produces alkalinity, which can be used to offset ocean acidification. At laboratory scale, the team demonstrated a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral...

ESA’s SMOS And NASA’s Aquarius Missions Monitoring Ocean Salinity
2013-04-22 14:21:15

ESA [ Watch The Video Freshwater Plume From SMOS And Aquarius ] The saltiness of the oceans is being closely monitored from space by both ESA´s SMOS and NASA´s Aquarius missions, but in slightly different ways. By joining forces, researchers are exploiting these complementary missions to benefit climate science even further. Everyone knows that seawater is salty, but it isn´t that obvious that the concentration of salt — the salinity — of the surface waters...
