  • Oysters act as a natural seawater filtration system

    Environmental educators in Pensacola are acquainting kids with water filtration in a new, hands-on way. Instead of a class turtle, these students are raising baby oysters. This program is sponsored by the Pensacola Bay Oyster Company and supports a local nonprofit, the Bream Fisherman Association, in its efforts to ...

  • Marine Monitoring to Maximise the Performance of Marine Machinery

    Considering the cost of putting to sea, it is well worth investing in vibration monitoring equipment that can help engineers to protect and maximise the performance of marine machinery. Here, we discuss the challenges facing engineers and offers advice on how to successfully install and use vibration sensing equipment on marine vessels. As machinery has become more complex and mankind has ...

  • New approaches for monitoring the marine environment: the case of antifouling paints

    Protection of ships hulls against biofouling has been a problem since man began sailing the seas. The most common protections are specially produced antifouling paints. These paints could be broadly classified in three main groups, or generations, depending on the technology applied: first generation copper-based, second generation organotin-based, and the new, third generation, organotin-free ...

  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • The analysis of polycyclic aromatic hydrocarbons in marine samples

    Polycyclic aromatic hydrocarbons (PAH) have been determined in marine samples for many years, but have only rarely been included in either national or international monitoring programmes. PAH can arise in the environment from natural sources, oil and petroleum products and combustion processes. Although oil spills influence PAH concentrations in local areas, the major sources of PAH are ...

  • 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 ...


  • Volunteers in Marine Conservation Monitoring: a Study of the Distribution of Seahorses Carried Out in Collaboration with Recreational Scuba Divers

    Abstract: Seahorses ( Hippocampus) live in tropical and temperate waters. Habitat degradation and fishery overexploitation have led to drastic population declines on a global scale. Population monitoring is therefore essential to determine current status and manage conservation. In this first study in Italian waters on the geographic and ecological distribution of the two ...


  • Array technology as a tool to monitor endocrine disruption in wild fish populations, Marine Environ Res.

    A variety of anthropogenic chemicals are capable of binding to the estrogen receptor of vertebrate species. Binding of these compounds can interfere with homeostasis by disrupting normal gene expression patterns. The purpose of this study was to investigate the feasibility of applying array technology as a monitoring tool for detecting the presence and distribution of estrogenic compounds in ...

  • 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 ...

  • Path planning for marine fleet using heuristic approach

    Nowadays, the use of unmanned vehicles for border monitoring is taking over in order to reduce the effort of human operators. This paper addresses the problem of the coastal patrolling by proposing a solution based on unmanned underwater and surface vehicles. The focus of the work is on the design of the routes for the unmanned vehicles so as to optimise the limited mission range of the robotic ...

  • A dynamic model of optimal reduction of marine oil pollution

    This paper proposes a system of dynamic models to describe the interactive behaviour of different agents (polluters, inspectors, and a principal pollution control agency) involved in the processes of marine oil pollution and of its prevention and purification, under some realistic assumptions. In particular, short- and long-term economic responses of polluters to monitoring efforts, as well as ...

  • Bio-fouling control on marine vessels with ozone

    A recent pilot study on how to control accumulation of marine organisms on heat exchangers of marine vessels show that applying ozone is both effective and sustainable. Large economic impact Marine bio-fouling, or accumulation of marine organisms on heat-exchangers for cooling systems, is a challenge in the maritime sector and has both an economic and environmental impact. Worldwide ...

  • 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 ...

  • 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 ...

  • Marine Birds as Indicators of Arctic Marine Ecosystem Health: Linking the Northern Ecosystem Initiative to Long-Term Studies

    Marine birds are sensitive indicators of the condition of marine ecosystems in the Arctic, partly because they feed at the top of the arctic food chain. The Northern Ecosystem Initiative (NEI) recently supported four separate studies that investigated aspects of Arctic marine bird science which simultaneously addressed goals of the NEI to better understand northern ecosystems and their response ...

  • The inter-tidal zone is the pathway of input of enterococci to a subtropical recreational marine beach

    Efforts were made to evaluate the source of enterococci levels at a recreational beach. Four monitoring efforts were implemented which included tidal studies, hourly sampling, runoff sampling, and spatially intensive sediment sampling. Spatially intensive sediment sampling indicated that enterococci concentrations consistently decreased away from the inter-tidal zone, both seaward and landward. ...

  • Human pharmaceuticals in the marine environment: Focus on exposure and biological effects in animal species

    Marine waters have been poorly investigated for the occurrence of pharmaceutical contamination. Recent data confirm that pharmaceuticals widely occur in marine and coastal environments; therefore assessment of potential risk to marine species needs further efforts. The present paper represents the first extensive review of pharmaceutical contamination in marine environments addressing the ...
