Wadden Sea dal basin inventory and analysis- a pre-study Preliminary results
dedicated for the PRW “Programme towards a Rich Wadden sea”
D. Kra , E. Folmer, T. S ehl, J. Meyerdirks et al. 2010 Supervision: Justus van Beusekom (AWI Sylt), Norbert Dankers (Imares), Morten Pejrup (Univ Copenhagen)
backing by Bruno Ens, Katja Philippart, Albert Oost Objec ves
• Comparison of dal basins with regard to differences in – abio c features, – ecological developments and – applied policy and management, with the aim of be er understanding cause-effect rela onships between them. • A database and digital atlas shall contain – the most important physical and biological parameters, – human interference and applied management, as a reference for research and policy.
kra et al. 2010 PRW: dal basin inventory pre-study: preliminary results 2 goals of the pre-study
• To get a idea of: – Which dal basin are there? – What are their characteris cs? – What cause-effect rela onships dominate? – What are the research & policy ques ons? – Where are they located? – What data do we need to answer this ques ons? – What data are exis ng? How accessible are they? • Asking experts!

What are the rela onships between bioengineers and environmental condi ons? 3. What are the effects of exploita on and anthropogenic disturbance? 4. What do we want the WSA to be like? 5. What is the rela onship between geomorphology and ecosystem func oning? 6. Is it possible to dis nguish between naturally driven and anthropogenically driven popula on dynamics? 7. How will exo c species affect ecosystem func oning?

• A lot of data is available! – Quality: sufficient/rich – Accessibility: hard/common – Vote: medium/rich • A lot of knowledge exists, but we need an intelligent combina on of data with remote sensing and models!
kra et al. 2010 PRW: dal basin inventory pre-study: preliminary results 32 Outlook
• What exactly is needed: – digital atlas of the Wadden? Yes! – a database? Not necessarily! – informa on system? Might be an op on! – online pla orm? Should be the over-all goal! – more research is needed on so ware architecture to integrate data, models and remote-sensing!
