ABSTRACT
From the workshop, four areas worthy of further investigation were identified, and workgroups were established to continue development of knowledge and understanding. Workgroups are still discussing and developing their ideas, and hence these reports describe the objectives and preliminary results of each workgroup but should not be viewed as the final agreed outcome. The purpose of these reports is to generate interest and to provide the basis for further discussion and research. In addition it was recognized that there is a need to develop tools for spatio-temporal extrapolation of microcosm and mesocosm results. This activity would also be a topic for further research.
