Acoustic Monitoring of Marine Wildlife

[ report an error in this record ]

    Eventtype: Conference/Workshop
    Period: 2007-09-13 - 2007-09-14
    Location: National Physical Laboratory, London, UK

    This year has seen a yet more profound public appreciation of the impact of man's activities on the environment. Global warming, polar melting, vanishing krill and fish-stocks, even the "Thames Whale". The list increases by the week. Marine windfarms, tidal turbines, seismic exploration, oil extraction and naval activity provide examples of how noise is generated to the detriment of marine wildlife. Disquiet over the plight of the oceans is leading to an insistence on Environmental Impact Assessments (EIA) prior to marine exploitation. Measurement of the underwater noise caused by man's activities, assessment of its significance and mitigation of its effects are now key requirements in the EIA. Marine mammal or fisheries observers capable of monitoring shipboard practice are in great demand. Personnel competent to handle these activities are urgently sought by employers
    engaged in defining or meeting EIA requirements.

    Course Objectives
    Comprehensive training for marine biologists, oceanographers and others involved in monitoring, EIA and similar activities. Clear, quantifiable scientific understanding of the impact of high-power acoustics on marine wildlife. Appreciation of acoustics as the preferred monitoring tool.

    Who Should Attend ?
    This course will be of value to marine wildlife monitors as well as the developers and users of
    civil and military sonars. It will also be of importance to planners and legislators concerned with EIA, with the conduct and supervision of seismic surveys, marine civil engineering projects, mineral extraction projects and major naval excercises involving high-power sonar. Delegates are strongly advised to attend the Basic Underwater Acoustics course prior to this one.
