  • 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 ...

  • Use of marine outfalls in wastewater disposal

    Global experience has shown that disposing of properly treated domestic wastewater through effective ocean outfalls is an economical and reliable strategy for wastewater disposal with minimal environmental impact. Better construction techniques, such as tunnelling, coupled with improved materials mean that the technology of marine wastewater disposal has advanced rapidly in recent years. ...

  • Opinion: What is Marine Spatial Planning

    A SYSTEM OF INTEGRATED MARINE MANAGEMENT FOR UK WATERS The United Kingdom marine area is far greater than that of its landmass.1 The coastal areas and seas have provided convenient food, transport and waste disposal for centuries, as well as contributing to man's identity and sense of well-being. In recent years, biodiversity and the potential of biotechnologies from the oceans have ...


  • An ecologist's view of economic instruments and incentives

    Advice by fisheries scientists to reduce catches or effort is often not fully implemented and efforts to increase impact of advice have often failed. Fisheries scientists rarely discuss the potential contribution of economic instruments to improving the impact of science advice. This paper rejects several possible justifications for the absence of discussion on economic instruments in fisheries ...

  • Tekran instruments—monitoring around the world

    Tekran provides trace-level mercury analytical and monitoring technology for a variety of applications including laboratory-based sample analysis, continuous point-source emissions and ambient air monitoring. This article focuses on and highlights the results of an application of Tekran’s Ambient Air Mercury Speciation System. In contrast to most other heavy metals, mercury (Hg) and mercury ...

  • Trace metal status in marine biological samples: a review

    The literature on trace metal status in marine biological samples is reviewed, taking into account the importance of the subject. Marine organisms accumulate trace metals to body concentrations well above those in seawater. Different marine organisms differ significantly in accumulated tissue and total body concentrations of heavy metals. The present literature survey indicates that more than 26 ...

  • Fish out of water — marine management in a changing climate

    A fisherman's tale: on the night of 6 October 1986 lobster fishermen from the small town of Gilleleje, north of Copenhagen, fishing the Kattegat Sea, found their nets crammed with Norway lobster. Many of the animals were dead or dying. About half were a strange colour. Observations of dissolved oxygen in the water in combination with the dead lobsters told researchers at the National ...

  • The investigation of compositional and structural characteristics of natural marine organic matter: a review

    The natural marine Organic Matter (OM) is a complex mixture of carbohydrates, lipids and proteins present in seawater and sediments, able to affect many processes occurring in the marine environment such as the biochemical cycles of marine nutrients and living organisms. As the complexity of environmental studies concerning OM composition requires the application of accurate analytical methods, ...

  • Automated techniques for real-time shipboard determination of dissolved trace metals in marine surface waters

    This review compares methods that are currently employed for shipboard analysis of trace metals in seawater voltammetric, chemiluminescence and colorimetric methods. Instrumentation and methods are described for collecting surface seawater using pumping, with subsequent on-line analysis by stripping voltammetry. The review is illustrated with data for oceanic and coastal distributions of ...

  • Application of multivariate methods in the monitoring of marine environment: simultaneous determination of bromide, bicarbonate, nitrate and sulphide in seawater by ultraviolet spectroscopy

    In this paper we present a new ultraviolet (UV) spectroscopic method for the simultaneous and reagentless determination of bromide, bicarbonate, nitrate and sulphide ions in artificial seawater solutions, applicable to the monitoring of the marine environment. We collected the UV spectra of artificial seawater samples with salinity between 8 and 45 psu, having known concentrations of these ...

  • Supporting wave and tidal energy in the UK - an analysis of UK Policy 2000-2009

    In order to stimulate UK based marine energy technology developers, the UK Government launched the Marine Renewables Proving Fund (MRPF) in 2009. This instrument was designed to bridge the gap between early-stage research funding and the recently-criticised Marine Renewables Deployment Fund (MRDF). This paper develops an analysis framework for policy instruments designed to support technology ...

  • Geo-engineering, the Law of the Sea, and Climate Change

    Plans to address climate change increasingly include proposals for geo-engineering projects, whose effects are likely to be global, at best only partly predictable, not necessarily wholly benign, and extend beyond their objective. Geo-engineering proposals should receive detailed, precautionary scrutiny by the international community, which requires sophisticated international legal instruments ...

  • Stochastic models of oil spill processes

    This paper models the occurrence of an environmental accident as a stochastic event. In particular, the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and size of spills. It is shown that both the time distribution of different types of oil spill and ...

  • Handling of a large dataset: application of Time Series Analysis to oceanographic studies

    This paper describes the application of the specific Time Series Analysis techniques (TSA), Autocorrelation analysis (AC), Crosscorrelation analysis (CC) and Power Spectral Density (PSD) to elaborate a large set of oceanographic data, such as marine pressure, flow and current. The data were collected by ad hoc oceanographic instrumentations in two different sites of the Italian seas as digitised ...
