The National Oceanography Centre (NOC) has developed the first ever global wind speed products based on reflected GPS signals, using data from the UK TechDemoSat-1 satellite. This demonstrates the potential of this technique to improve sampling of ocean surface winds, as well as improve weather monitoring and forecasting by complementing existing satellite measurements from scatterometers and ...
Ninety-eight per cent of radioactive iodine in Arctic sea ice may come from Europe, new research suggests. The study concludes that atmospheric transport of Iodine-129 from European nuclear fuel reprocessing plants is the most likely source. Iodine-129 (129I) is a long-lived (half-life of 15.7 million years) radioactive form of iodine that occurs naturally in very small amounts. It is highly ...
Pioneer Valley High School science teacher Riccardo Magni received a presidential award plaque from the U.S. Environmental Protection Agency at a ceremony today in Santa Maria, Calif. Magni was the only Calif. award winner out of 18 instructors recognized this year nationwide. The Presidential Innovation Award for Environmental Educators (PIAEE) program was recently created by a partnership ...
Federal and state agencies have begun important research to evaluate the suspected discharge of pollutants to the coastal waters along the Kaanapali coast of Maui. Funded by the U. S. EPA, U.S. Army Corps of Engineers, and the Hawaii Department of Health, the University of Hawaii will measure how long it takes for wastewater from the Lahaina sewage treatment facility to flow to the near-shore ...
An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs -- snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. Before now, small RNA could only be studied in lab-cultured microorganisms; the discovery of its presence ...
A new landmark study published today documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an ...
As ocean currents and eddies form height undulations on the sea surface of the order of tens of centimetres, altimetry results gradually yield to a rich and scientifically valuable map of ocean circulation. Current altimeters sample only one point at a time, while PARIS would measure multiple points with a faster revisit time, yielding new data on rapidly-changing features. ...
