  • Ship-mounted Direct and Diffuse Hyperspectral Radiometers successfully measure Solar Irradiances and Aerosol Optical Depth

    Marine AOD measurements matter because aerosols can affect respiratory health, climate change, and the safety of aircraft during volcanic events. However, routine marine Aerosol Optical Depth (AOD) surface-based observations are in short supply because it is both difficult and expensive to operate conventional automatic sun photometers at sea. Two prototype hyperspectral radiometers have shown ...

  • Monitoring hydrocarbons in Bilge water - Case study

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged ...

  • The Ecological Fishprint of Nations: Measuring Humanity’s Impact on Marine Ecosystems

  • Application of passive sampling for measuring dissolved concentrations of organic contaminants in the water column at 3 marine superfund sites

    Currently, there is an effort under way to encourage remedial project managers at contaminated sites to use passive sampling to collect freely dissolved concentrations (Cfree) of hydrophobic organic contaminants to improve site assessments. The objective of the present study was to evaluate the use of passive sampling for measuring water column Cfree for several hydrophobic organic ...

  • 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. ...

  • 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 ...


  • Marine crude oil transport – global voyage losses

    Paul Harrison, Consultant to the HMC-4A Marine Oil Transportation Database Committee, presents latest findings from analysis of the 2013 data on marine crude oil transport. The Energy Institute (EI) HMC- 4A Marine Oil Transportation Database Committee has been collecting and analysing worldwide oil shipping data for over 20 years and meets twice a year. The 2013 autumn meeting was held in Rio de ...

  • 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 ...

    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 ...

  • Expanding marine protected areas to restore fisheries

    After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand. In response, the oceanic fish catch climbed from 19 million tons ...
