WaLTER_Wadden Sea Long-term Ecosystem Research

Why we started WaLTER

In the Wadden Sea, many parameters of the physical, ecological and socio-economic system are monitored by various institutions These measurement efforts were not always well aligned and the data were not always fully accessible. Starting in 2011, the WaLTER project has collected and evaluated the fragmented data and information to improve both the long-term monitoring programs and the accessibility of the data for the Dutch Wadden Sea.

Wadden Sea Cloud

How we proceeded

We made an inventory of knowledge and data requirements, performed scientific analysis of ecological and socio-economic models, and evaluating measurement programmes, identifying gaps & overlaps. Furthermore we secured data access in a standardized format via a central portal

What we achieved

We built a data portal with more than 10.000 data sets. We make recommendations for fundamental monitoring (12 thematic reports), present an overview of long-term monitoring programmes (EVA factsheets), and a tool for calculating exposure time of intertidal area (InterTides). In addition, we compiled a thematic collection of digital maps (Maps portal), and constructed a database of ecology and socio-economy of Wadden area (SEED), complemented with the relevent scientitific papers.
