Pilotonderzoek vleermuizen vangen en volgen over zee
Door een groeiend belang van nieuwe maritieme sectoren neemt de bestuurlijke drukte op zee toe. In dit project is een kwalitatieve scenarioanalyse uitgevoerd om te beschrijven hoe de gebeurtenissen zich in de toekomst kunnen ontvouwen, om risico’s te identificeren en om zo beslissers in staat te stellen over verschillende ontwikkelrichtingen te oor...
This project looked at the effect of closing an area for fisheries on the development of the benthic community. An existing data set of benthic species densities sampled at different distances and angles from a platform was used for this purpose. The particular area was closed due to the installation of a gas production platform, but is likely to f...
Alle VMS-gegevens bestaan uit een locatie, snelheid en tripnummer. Deze kunnen middels het tripnummer worden gelinkt aan de logboek data. Hierdoor wordt voor elke trip bekend welk tuig gebruikt is, en wat de (geschatte) aanlandingen waren per soort. Voor elk tuig apart wordt per VMS-ping bepaald of het schip op dat moment vissende is. Dat wordt bep...
Within this study, we quantify the fishing intensity that is allocated at the various sediment- and energy habitats type areas found in the North Sea by selected Dutch bottom fishing vessels. For 2010 traditional beam trawlers and for 2014 pulse trawlers are selected. Trawling frequency, as a measure of impact, equals the surface area covered by th...
On the North Sea bottom lie numerous pipelines to link oil- or gas offshore drilling units, - platforms and processing stations on land. Although pipeline tubes are coated and covered with protective layers, the pipelines risk being damaged through man-made hazards like anchor dropping and fishing activities with bottom trawls. This study provides,...
WWF Netherlands has developed a proposal for a network of Marine Protected Areas (MPAs) in the North Sea. Most of the MPAs in this network are already protected under the Natura 2000 framework and/or the Marine Strategy Framework Directive. WWF Netherlands aims to engage with stakeholders and build support for this proposed MPA network. One of the ...
