There are many signals that different human activities affect the marine ecosystem on local and sometimes regional scales. There is evidence that in the Dutch sector of the North Sea at least 25 species have decreased tremendously in numbers or have totally disappeared. But what has caused their disappearance: fisheries, pollution, eutrophication, climatic(More)
This paper describes the construction, validation and application of a mathematical ecosystem model of the western Wadden Sea. This model is based upon the Ems-Dollard ecosystem model, but also includes a two-dimensional transport submodel, a benthic and epibenthic sublitoral submodel and nutrient regeneration. In 1986, an extensive field programme was(More)
Offshore platforms are known to act as artificial reefs, though there is on-going debate on whether this effect is beneficial or harmful for the life in the surrounding marine environment. Knowing what species exist on and around the offshore platforms and what environmental variables influence this species assemblage is crucial for a better understanding(More)
Over a decade of monitoring offshore wind park environmental impact triggered a reflection on the overall objectives and how to best continue with the monitoring programmes. Essentially, basic monitoring has to be rationalised at the level of the likelihood of impact detection, the meaningfulness of impact size and representativeness of the findings.(More)
The European Academy of Wind Energy (eawe), representing universities and institutes with a significant wind energy programme in 14 countries, has discussed the long-term research challenges in wind energy. In contrast to research agendas addressing shortto medium-term research activities, this eawe document takes a longer-term perspective, addressing the(More)
The effects of climate change on economic development in the coastal zone cannot be ignored in future coastal zone management plans. This chapter reports the outcome of the group discussion centred round the three questions posed by Nicholls and Klein on how the coastal zone can be effectively managed in the future. The first question asked how we can marry(More)
We studied short-term changes in macrozoobenthos in a 20m deep borrow pit. A boxcorer was used to sample macrobenthic infauna and a bottom sledge was used to sample macrobenthic epifauna. Sediment characteristics were determined from the boxcore samples, bed shear stress and near-bed salinity were estimated with a hydrodynamic model. Two years after the(More)
The knaw collaboration projects, which were aimed at the promotion of quality researches in Indonesia, have succeeded over the years in the establishment of effective ‘beach heads’ of scientific research which are still relatively rare in this country. The resources assembled and experience accumulated in the processes have begun to show promising(More)
Light dependent sediment-water exchange rates of dissolved reactive silicon (DRSi) and phosphorus (DRP) were studied on field station Archipel (3 m water depth) in Lake Grevelingen (SW Netherlands). Bell jars, either light or darkened, were fixed permanently over a productive microflora mat of mainly Navicula spp.; sediment-water exchange was monitored over(More)
Coastal development in Banten Bay, Indonesia, decreased seagrass coverage to only 1.5% of its surface area. We investigated the importance of seagrass as habitat for juvenile groupers (Serranidae) and snappers (Lutjanidae), by performing beam trawl hauls on a weekly basis in two seagrass locations and one mudflat area, and monthly trawl hauls in three(More)
