  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Dissolved Organic Nitrogen Measurement in Reclaimed Water

    Dissolved organic nitrogen (DON) is an emerging concern for wastewater reclamation and reuse communities since DON may react with disinfectants to form carcinogenic nitrogenous disinfection byproducts (DBP) (e.g., haloacetonitriles, N-nitrosodimethylamine (NDMA)) and to affect the speciation of currently regulated DBP (trihalomethanes and haloacetic acids). Also, DON is present in proteins that ...

  • Marine specimen banking: archive and pollution control for the 21st century
