  • Marine hydrogeology: recent accomplishments and future opportunities

    Marine hydrogeology is a broad-ranging scientific discipline involving the exploration of fluid–rock interactions below the seafloor. Studies have been conducted at seafloor spreading centers, mid-plate locations, and in plate- and continental-margin environments. Although many seafloor locations are remote, there are aspects of marine systems that make them uniquely suited for hydrologic ...

  • A New Microbial Contact Assay for Marine Sediments

    The number of microbiological contact tests for marine sediments is low, although microorganisms enable a rapid screening and monitoring of sediment quality and a high resolution of hazard assessment. As no single biotest can provide reliable answers concerning the potential hazard of environmental samples, a combination of bioassays needs to be applied to serve this purpose. In order to cover ...


  • Biological effects of contaminants on marine organisms: the contribution of biotechnology

    One aspect of ecotoxicology concerns the effects of contaminants. Work on this area in the marine field is recent but useful for numerous applications, such as toxicological tests, the evaluation of organism response and the development of networks for the measurement of pollutant effects. In this context, the contribution of biotechnologies and technical advances in modern biology is important. ...

  • Interviews: Ken Buesseler, Researcher into marine discharges at Fukushima

    We as scientists do have a responsibility and I hope to be able to contribute in some way“ Ken Buesseler, researcher at the Wood Hoods Oceanographic Institute is investigating the radioactivity leaked from the Fukushima nuclear power station, initially from data facilitated by the TEPCO (Tokyo Electric Power Company) and then from samples gathered in situ. He believes that official bodies ...

  • Creative Uses of TenCate Geotube Marine Technology Continue to be Instrumental for Unique Marine Applications - Case Study

    Backed by proven, innovative methods, Geotube units offer key advantages for many distinctive marine structure projects. Thanks to Geotube marine technology, the waterfowl of Lake Sinissippi (Wisconsin) now enjoy an improved wildlife habitat, and the residents near Lac Saint-Jean (Quebec) no longer worry about shoreline erosion issues. Geotube marine structures were successfully installed in ...

  • Marine phanerogams as a tool in the evaluation of marine trace-metal contamination: an example from the Mediterranean

    New ways of evaluating the quality of the coastal marine environment in a practical, dependable and cost-efficient manner are continually sought. It would thus appear of some value to make use of bioindicator species that reflect both the average levels and the temporal variations of contaminants at a given site. Owing to their extensive distribution in the littoral zone and the ecological ...

    Geotube units are fundamental for distinctive marine structures using proven, innovative methods and techniques. What does a Honduran mine debris dam have in common with an iconic cable-stayed bridge in Korea? Both structures were built using Geotube marine technology, an important component in the design of these projects. Geotube marine technology has proven successful in the ...

  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • A Multi-Sensor Piezometer for Shallow Marine Sediments in Coastal Environments

    A multi-sensor piezometer has been developed to measure dynamic excess and ambient pore pressures in shallow marine sediments under the effect of surface waves, tides, and currents. The probe consists of a shaft (1.5 m long with five porous stones at subseafloor depths ranging from 0.10 to 0.93 m) and two upper chambers (one that is hermetically sealed for the transducer electronics and another ...

  • Marine atmospheric boundary-layer height estimated from NWP model output

    The application of the bulk Richardson number approach to determine the height of the marine atmospheric boundary layer from standard output of Numerical Weather Prediction models is discussed. It is argued that over smooth surfaces like the sea, the critical Richardson number can be expected to be smaller than over land. Based on 4 days of intensive measurements of the height of the marine ...
