Opportunity of automated flow cytometers continuous recording during a Cefas Nephrops survey in the North Sea in June 2016. The objective of the Nephrops survey is to assess fishery independent indicators of stock size, exploitation status and catch advice with Underwater TV recording of Nephrops norvegicus. Besides, other types of data were collected such as surface (4 m) salinity, temperature, fluorometry, oxygen and pH and Fe/Fm from the ‘Ferrybox’, and phytoplankton functional types with 2 flow cytometers (Cytosense) from Cefas and RWS.

Long term measurements of phytoplankton composition in the Dutch national part of the North Sea. Samples were taken 12 - 24 times per year between 1990 and 1999 and analysed to the level of genus, species, or other taxon group. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive. Currently, there are known issues concerning the quality of the data caused by changes in analytic procedures and labs. When more information is available, this will be published through EMODnet.

Long term measurements of benthos composition in the Dutch national part of the North Sea. Samples have been taken by benthic sledge, box-corer, video and Hamon sampler. Samples were taken annually between 1991-2010, in 2012 and in 2015 and analysed to the genus or species level. For video sampling, coverage percentages were measured. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive.

Dutch long-term monitoring of microzooplankton in the Dutch Continental Economical Zone of the North Sea between 2000 and 2010. This monitoring program was part of the MWTL phytoplankton sampling.

<p>Aerial surveys with bird observations around the off shore wind farm Borssele (North Sea). It is acquired for gaining insight in spatio-temporal behavior of patterns of birds. RWS case number: 31163291.</p>

Breeding bird data for 7 water birds (Bontbekplevier, Dwergstern, Grote stern, Kluut, Noordse Stern, Strandplevier, Visdief) in the Delta area, the Netherlands, in 1979 and 1987. The data were digitized by VLIZ from the original report: Baptist, H.J.M.; Colijn, F.; Marteijn, E.C.L.; Meininger, P.L.M.; Meire, P.M.; Twisk, F. (Ed.) (1988). Gevleugeld onderzoek: watervogels in veranderende watersystemen. University of Gent, Laboratory of oecology of animals, zoogeography en nature conservation: Gent. 22 pp.

Port of Rotterdam is carrying out the Project Mainport Development Rotterdam, PMR, expanding the port with 1,000 hectares through suppletion of sand in the shallow coastal Voordelta area in the North Sea. As the Voordelta has the status of protected nature reserve (Natura2000 area), the loss of habitat, caused by the expansion of the port, must be compensated for. As part of the compensating measures, the Dutch national government established a series of protected areas in the Voordelta region and is following the effects of these measures. This dataset comprises abundances of macrozoobenthos, fish and birds in the “Voordelta”. The set exists of a pre-protected status data (2003 – 2007) and a post-protected status (currently still under embargo).

Long term measurements of phytoplankton composition in the Dutch national part of the North Sea. Samples were taken 12 - 24 times per year between 2000 and 2018 and analysed to the level of genus, species, or other taxon group. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive. Currently, there are known issues concerning the quality of the data caused by changes in analytic procedures and labs. When more information is available, this will be published through EMODnet. The monitoring is directed and the dataset is maintained by Rijkswaterstaat, the executing body of the Dutch Ministery for Infrastructure and Environment. Publication of the dataset has been facilitated by Deltares, The Netherlands.
