  • Observing arctic ice-edge plankton blooms from space

    Ongoing climate-driven changes to the Arctic sea-ice could have a significant impact on the blooming of tiny planktonic plants (phytoplankton) with important implications for the Arctic ecosystem, according to new research conducted by scientists at the UK\'s National Oceanography Centre (NOC). Advances in modern satellite technology offer the opportunity to observe and monitor ice-edge blooms at ...


  • ASTM D4638 - 11 standard guide for preparation of biological samples for inorganic chemical analysis

    The chemical analysis of biological material, collected from such locations as streams, rivers, lakes, and oceans can provide information of environmental significance. The chemical analysis of biological material used in toxicity tests may be useful to better interpret the toxicological results. Many aquatic biological samples, either as a result of their size, or their method of collection, ...

  • Plastic found in stomachs of over 1 in 6 large pelagic fish sampled in Mediterranean Sea

    Plastic pollution in the ocean is a growing problem. This study, which is the first to investigate the presence of plastic debris in large pelagic fish in the central Mediterranean Sea, found that over 18% of fish had ingested plastics. Marine litter, defined by the European Commission as any persistent manufactured or processed solid material discarded, disposed of or abandoned in the marine ...

  • The Chelsea Mariner Shuttle for Large Marine Ecosystem Monitoring

    The new Chelsea Mariner Nu-Shuttle is based on the successful Nu-Shuttle towed oceanographic vehicle. It is a generic, robust monitoring system designed for regular monitoring of large marine ecosystems. Undulating behind a research vessel or ship of opportunity it enables a wide range of oceanographic measurements to be made underway from the surface to depths in excess of 150 metres. ...

  • IFCB in new Long-Term Ecological Research Site

    Imaging FlowCytobot samplers (IFCBs) manufactured by McLane will be installed in a new Long Term Ecological Research (LTER) site off the Northeast coast of the United States. LTER programs focus attention on specific sites representing major ecosystem types, and undertake long-term assessments of populations, communities, and the physical environment. ...

  • Ocean pH value decreasing

    A research project into ocean acidification has increased knowledge about conditions in the Baltic Sea and Kattegat-Skagerrak. When the pH value falls, the whole marine ecosystem is affected. A newly developed measurement technique provides information about natural variations in the oceans, which results in improved environmental monitoring. Since 1850 the pH value of the world’s ...

  • Plastic pellets everywhere, and diving robot sensors

    The Dr Fridtjof Nansen is plying the waves of the southern Indian Ocean, trawling for trash. Every time the ship's scientific crew threw down special nets, they hauled in pieces of plastics, underscoring the risk of dramatic upheavals in marine ecosystems even in one of the world's least-known and least-visited environments. An estimated 5 trillion ...

  • EPA christens new great lakes research vessel (IL, IN, MI, MN, NY, OH, PA, WI)

    U.S. Environmental Protection Agency (EPA) Assistant Administrator for Research and Development, Paul Anastas today joins Congressman Jim Oberstar, D-Chisholm in the christening of the Lake Explorer II, a new vessel to support EPA research in the Great Lakes Area. The vessel is being commissioned as the RV Lake Explorer II to support EPA research in the Great Lakes—a vast region with over ...

  • Careful land management protects Mississippi watersheds

    Agricultural Research Service (ARS) scientists at the National Sedimentation Laboratory (NSL) in Oxford, Miss., are studying how farming practices and conservation strategies can improve water quality in the Yazoo River Delta and beyond. As part of this effort, research leader Martin Locke and his colleagues have been tracking changes in the Beasley Lake watershed for more than a decade. During ...

  • Deep-water fish remove over a million tonnes of CO2 in Irish-UK waters every year

    Deep-water fish living along the Irish-UK continental slope remove more than a million tonnes of CO2 from the atmosphere each year, according to a recent study. Continental slope ecosystems play an important role in carbon sequestration, which should be considered before exploiting deep-water resources, say the researchers. Transport of carbon from the ocean surface to deep water is affected by ...

  • New method for detecting microplastic particles in fish stomachs

    A novel approach for identifying and isolating anthropogenic – including microplastic – particles in fish stomachs has been devised by researchers in Belgium. The new method may enable scientists and policymakers to better assess the presence, quantity and composition of particles ingested by marine life, and improve understanding of the environmental effects of marine plastic ...

  • The Institute of Oceanology, China has just taken delivery of a Chelsea SeaSoar towed oceanographic vehicle system

    Note: This press release is intended for media focusing on Ocean Business 9-11 April 2013. If you plan to use it in your online publication I'd be really grateful if you could feature it as near to the exhibition as possible. Thanks!   The Institute of Oceanology Chinese Academy of Sciences (IOCAS), Qingdao, has just taken delivery of a Chelsea ...

  • Long-term seawater analysis has global significance

    Since 1988, scientists from the University of Hawaii have been conducting almost monthly deep-sea research expeditions to collect water samples for subsequent laboratory analysis. Originally designed to characterize subtle long-term changes in environments that were believed to be stable, the work has revealed some surprising conclusions. For example, it has become evident that even in these ...

  • Protozoa detect water toxins

    Woods Hole Oceanographic Institution (WHOI) biologist Scott Gallager has grand plans for his revolutionary Swimming Behavioural Spectrophotometer (SBS), which employs one-celled protozoa to detect toxins in water sources. The SBS has been selected as a 2010 ‘Better World\' technology by the Association of University Technology Managers. This success story was actually a concept which the US ...
