Approach to the use of uncertainty for management purposes - study Case: Quantification of the uncertainty in the turbidity for the ecosystem of the Wadden Sea

Around the world, areas with unique ecosystems are prone to harmful factors deteriorating their environment. Management of these areas need knowledge on the ecological status of these areas, to make decisions for future problems. They need easily accessible information on indicators describing the conditions of these areas. Obtaining this...

The risk of exceeding a certain threshold for Chlorohyll-a in the Wadden Sea

The Ecostress project has the intention to develop systems and methodologies to observe changes in urban coastal areas. Within this project, the Wadden Sea is taken as a pilot area. The goal is to produce tools to assess human, social and environmental impacts, such as the spatial risk and socio-environmental impacts of coastal urbanization. One...

Improving the Algal Bloom Prediction in the North Sea by Ensemble Kalman Filtering in the GEM/BLOOM Model

The ecological state of the North Sea surface water can be indicated by ocean variables such as the Chlorophyll-a (Chlfa) concentration. Chlfa is the principal photosynthetic pigment and is common to all phytoplankton and can therefore be used as a measure of phytoplankton biomass. The GEM/BLOOM model developed at Deltares is a generic...

Improving the Algal Bloom Prediction on the North Sea by Dual Ensemble Kalman Filter in GEM Model

Increasingly, the phytoplankton blooms (algal blooms) become a public health concern and a worldwide ecological problem. The Generic ecological model (GEM) plays a very important role to assess ecological quality of the Dutch coastal waters and the southern North Sea. Algal blooms can also be predicted by the GEM model mainly through chlorophyll...
