An ICES workshop on biological effects in pelagic ecosystems (BECPELAG): overview of the programme

No abstracts are to be cited without prior reference to the author.The ICES biological effects monitoring in pelagic ecosystems workshop (BECPELAG) is a multi-national, multi-dicipline workshop aimed at establishing suitable techniques for monitoring the effects of contaminants on pelagic ecosystems. During seven research cruises in 2001, pelagic organisms were collected and caged deployed at four sites in the German Bight and at four sites in a downsteam transect from an oil platform in the North Sea

An ICES workshop on biological effects in pelagic ecosystems (BECPELAG): summary of results and recommendations

No abstracts are to be cited without prior reference to the author.During and after three previous workshops, biological effects methods have been compared and refined. The first was held in Oslo in 1988, the second at Bermuda in 1990, and the third in Bremerhaven in 1992. All three workshops were held under the auspices of ICES and/or UN (GEEP, IOC). This activity is important insofar that it has stimulated research into the use of biological effects methods to monitor pollution impacts in marine ecosystems and contributed towards a framework for general and contaminant-specific monitoring. The objective of the BECPELAG workshop was to bring together scientists involved in relevant work in a practical workshop in order to assess the ability of selected methods to detect biological effects of contaminants in pelagic ecosystems and this is described in the overview of the project (session X first paper). In addition to biological analyses being performed by participants, laboratories were contracted to perform the chemical analyses required and hydrographers involved to provide models of water movement prior to and during sampling. The development of methods to assess the effects of contaminants in pelagic systems will be important for the development of future monitoring programmes in coastal waters and to understand impacts of oil production in the North Sea
