The implementation of the Water Framework Directive and EC Habitats Directive requires that the ecological status of all transitional and coastal waters be described. Traditional methods of sampling and laboratory analysis are unavoidably labour intensive and hence costly, and often involve a considerable delay between the commissioning of the survey and production of the report. The development of rapid assessment techniques that will provide repeatable and relevant data in a timely and cost effective way is therefore of considerable importance. This report details results of some possible approaches which may be adopted in the laboratory to achieve the above aims.
