Wadden Sea (dal basin inventory and analysis-‐ a pre-‐study Preliminary results

dedicated for the PRW “Programme towards a Rich Wadden sea”

D. KraB, 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 beYer 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.

kraB et al. 2010 2 PRW: (dal basin inventory pre-‐study: preliminary results

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!

vote:  overall “suitability”  rich/medium







What are the research and policy ques(ons?

1.  What are the fluxes of energy and maEer between trophic levels?

2.  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?


preliminary Resume

•  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!


Outlook

•  What exactly is needed: – digital atlas of the Wadden? Yes!

– a database? Not necessarily! –  informa(on system? Might be an op:on! – online plaoorm? Should be the over-‐all goal!

– more research is needed on so>ware architecture to integrate data, models and remote-‐sensing!
