  • Landmark US Geological Survey study demonstrates how methylmercury, known to contaminate seafood, originates in the ocean

    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 ...

  • Panama Canal Marine Resistivity Survey with SuperStingR8

    The AGI SuperStingR8 with marine streamer and graphite electrodes(US Patent 6,674,286) were deployed along the entire 77-km long Panama Canal at 25m transect spacing to total 773 line-km of data.  This is the largest towed marine resistivity survey of this type to date.  AGI SuperStingR8 Marine resistivity data were successfully used to estimate geotechnical properties of the canal ...

  • The risks of CO2 leakage through submarine ‘chimneys’

    NOC scientists are playing a key role investigating the risks of leaks from carbon dioxide (CO2) storage reservoirs situated under the seabed. Researchers from the National Oceanography Centre (NOC) will work with academics at the University of Southampton, who are leading the project, and the University of Edinburgh to better understand the risks involved in the storage of CO2 in depleted oil ...

  • Oceanographers discover toxic algae

    Louisiana State University, USA, researchers Sibel Bargu and Ana Garcia (Department of Oceanography and Coastal Sciences) have discovered toxic algae in vast, remote regions of the open ocean for the first time. The recent findings are published in the Proceedings of the National Academy of Sciences (PNAS). Harmful algal blooms (HABs) are reported as increasing both geographically and in ...


  • Tracking the UK`s carbon from soil to sea

    This January scientists from a range of disciplines will come together to undertake the first ever coordinated sampling of the major rivers in Great Britain to look for soil derived organic carbon. This carbon is a large element of our 'natural capital' - in fact it is so large that restoring some damaged elements of it, such as upland peat bogs, could cost up to £570 million over the next ...

  • Ocean Optics introduces handheld sensing system for field applications

    Now available from Ocean Optics is a handheld, field-portable analytical instrument that combines the power of optical sensing with onboard computing power for custom applications ranging from crop management and water analysis to UV radiation and ozone monitoring. Jaz is a family of stackable, modular and autonomous components -- a typical setup for field use is about the size of a few decks of ...

  • Methane release could cause abrupt, far-reaching climate change

    An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature. The shift triggered events that resulted in global warming and an ending of the last 'snowball' ice age. The ...

  • 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 ...


  • Energy Department advances research on methane hydrates – the world’s largest untapped fossil energy resource

    The Energy Department today announced the selection of 14 new research projects across 11 states that will be a part of an expanding portfolio of projects designed to increase our understanding of methane hydrates’ potential as a future energy supply. Methane hydrates are 3D ice-lattice structures with natural gas locked inside, and are found both onshore and offshore – including ...

  • EPA, NASA, NOAA and USGS Creating Early Warning System to Detect Harmful Algal Blooms

    The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. ...

  • Opinion: Geologists unveil how Britain first separated from Europe - and it was catastrophic

    As Brexit looms, Earth scientists have uncovered evidence of Britain’s original split from mainland Europe. Almost half a million years ago, according to new data, water suddenly started cascading over the narrow strip of land that joined England and France – putting pressure on a chalk bridge. Researchers show that, as a result, this ridge – a natural dam that separated the ...
