Last February the 8th, a trinational workshop on joint monitoring, evaluation and knowledge exchange concerning the Doggerbank was held in Hamburg. With several participants from Germany and the UK, Ecoauthor represented the Dutch government. Although monitoring programmes in the three countries are quite different, it is clear that cooperation will have benefits for each of the countries. As a first step, benthic monitoring data will be exchanged, and the various indicators in use will be applied on each others datasets. The tuning of evaluations should lead to a joint evaluation of the international Doggerbank region in the near future. Also joint monitoring activities are foreseen.
