  • Measuring Sediment Temperature

    Researchers from the University of Hawaii and PME developed a miniature thermistor chain to measure temperatures in surficial sandy sediments. The miniTchain was deployed for several months in 2010 and 2011 on the Kilo Nalu Cabled Observatory, which is located 200 meters off the coast of Honolulu, Hawaii. The miniTchain has thermistors mounted within a rigid frame and has several features to ...

  • Predicting sediment flow in coastal vegetation

    Original story at MIT News Seagrass, kelp beds, mangroves, and other aquatic vegetation are often considered “ecosystem engineers” for their ability to essentially create their own habitats: ...

  • Ancient glacial sediments drag down Louisiana`s sinking coast

    Sediments deposited into the Mississippi River Delta thousands of years ago when North America's glaciers retreated are contributing to the ongoing sinking of Louisiana's coastline, finds new research by NASA and scientists at Louisiana State University. The weight of these sediments is causing a large section of Earth's crust to sag at a rate of 0.04 to 0.3 inches a year, the study determined. ...

  • Plan to dump sediment on Great Barrier Reef OK`d

    The government agency that oversees Australia's Great Barrier Reef on Friday approved a plan to dump vast swathes of sediment on the reef as part of a major coal port expansion - a decision that environmentalists say will endanger one of the world's most fragile ecosystems. The federal government in December approved the expansion of the ...

  • Each degree of global warming might ultimately raise global sea levels by more than 2 meters

    Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the ...

  • ProMinent at IFAT 2016 - Elimination of man-made trace substances in municipal waste water treatment

    Man-made trace substances in drinking water are a continually growing problem. These compounds, for example from cosmetics and medicines, which are very resistant to biological decomposition, enter our drinking water reserves through waste water. In many cases, clarification plants have a fourth cleaning stage to remove this category of impurities and some countries, such as Switzerland, it ...

  • Methane gas likely spewing into the oceans through vents in sea floor

    Scientists worry that rising global temperatures accompanied by melting permafrost in arctic regions will initiate the release of underground methane into the atmosphere. Once released, that methane gas would speed up global warming by trapping the Earth's heat radiation about 20 times more efficiently than does the better-known greenhouse gas, carbon dioxide. An MIT paper that appeared online ...

  • Under a frozen lake in Siberia, UMass Amherst geoscientist drills for secrets of Earth’s ancient climate

    In the next few days, a convoy of bulldozers and trucks will set out from a remote airport in Siberia, heading for a frozen lake 62 miles north of the Arctic Circle, but the trip isn’t a holiday visit to the North Pole. Instead, the trucks will deliver core-drilling equipment for a study of sediment and meteorite-impact rocks that should provide the longest time-continuous climate record ever ...


  • Ex Situ Treatment of Aqueous Film-Forming Foam Impacted Groundwater

    Perfluoroalkyl and Polyfluoroalkyl Substances (PFASs) are common in Aqueous Film Forming Foams (AFFF) used for firefighting. PFASs are widely distributed across the higher trophic levels and are found in air, soil and groundwater at sites across the U.S. (EPA 505-F-14-001, March 2014). The toxicity, mobility and bioaccumulation potential of PFASs pose potential adverse effects for the environment ...
