2016: North Sea expedition: Towards a stronger MPA network

The North Sea (OSPAR Region II: Greater North Sea) is one of the busiest seas in the world. The impacts of intense anthropogenic activities in the area, including industrial fisheries and fossil fuel extraction, have perturbed the natural state of its ecosystems, which currently face major problems such as pollution, overfishing, habitat disturbance and eutrophication.

At the same time, in comparison with other OSPAR regions, the North Sea has the greatest percentage of protected areas (ca. 14%), with Denmark accounting for the highest percentage of coverage, followed by the United Kingdom (see Table 1) ( OSPAR 20141 ). However, most North Sea MPAs are relatively coastal; 63% are found within 1 nm from shore, and only 11% of MPAs occur in offshore waters (beyond 12 nm), about which less information is generally known (EEA 20152 ). Moreover, many existing MPAs in the region lack effective management.

To help address these issues, with the aim of strengthening the network of North Sea MPAs, Oceana carried out a two-month expedition* during July-August 2016, in the waters of Denmark, Netherlands, Norway, and the United Kingdom (see Expedition Route). Using a remotely operated vehicle (ROV) with a high-definition camera, professional SCUBA divers, and through grab sampling, Oceana collected first-hand data on species, habitats and communities in areas of potential ecological importance. The findings of these surveys are intended to be used to improve marine protection, both by developing proposals for new MPAs where gaps exist, and by strengthening the management of existing areas.
