|Croatian Marine Referral Centre (RCmore) performs systematic monitoring, observation and assessment of the state of the marine environment, fisheries and mariculture, collects and analyses of related data including indicators from the National List of Indicators for the Ministry of Environment and Energy of the Republic of Croatia. RC-more performs activities in six areas of work. The first area of work (PR-1) encompasses monitoring of the various marine environmental parameters needed to describe status of the eleven descriptors (D1-D11) within the framework of the implementation of the EU Marine Strategy Framework (ODMS). As there are still not enough funds to monitor all the defined parameters on a yearly basis, the priority parameters are included that have been regularly monitored for many years. Increasing the funds more and more parameters with increased spatial-time frequency will be included in monitoring.
