The data on marine sediment extraction will be reported to OSPAR on a yearly basis in Interim Reports. The other items will be addressed in Final Reports. During the Annual Meeting in 2013, at the beginning of the new 3-year period, WGEXT decides to formulate new Terms of Reference (ToRs), besides the existing ToRs A1 and A2, on topics which the group believe are important issues to be addressed. Nine new ToRs were formulated, most of them were intended for more than 3 years. The new Terms of Reference were: B (ICES aggregate database); C (Marine Strategy Framework directive); D (Publications); E (Mitigation); F (Deep sea mining); G ( Harmonization); H (Cultural Heritage); I (Cumulative assessment); J (Environmental Impact Assessment). During and between the annual meetings of 2014, 2015 and 2016 these ToRs were discussed and results were formulated. Contributions were provided by correspondence from members who could not attend. Yearly for all ICES-countries data on marine sediment extraction, including amounts of extraction, spatial extent of licensed areas, spatial extent of extracted areas, geospatial shapefile information is published in the Annual Reports and delivered to OSPAR. This input is necessary for the Quality State Reports and for the Marine Strategy Framework Directive of the European Union. The ICES database will be used for uploading the WGEXT information. A template for the WGEXT database was proposed. WGEXT will also continue to discuss the feasibility of developing the complexity of the database. Future expansion of the database is expected to be driven by inquiries from potential users. Concerning the Marine Strategy framework Directive an inventory is made on the way marine sediment extraction is mentioned in the MSFD documents. A review article on “Marine Aggregate Extraction and Marine Strategy Framework Directive: A review of existing research” is nearly finished. The possibility of recovery after sediment extraction should be acknowledged by incorporate it in the criteria and by taken it into account with the assessment of the Good Environmental Status. At the ICES Annual Science Conference 2016 a session is initiated by WGEXT on “Making marine sediment extraction sustainable by mitigation of related processes with potential negative impacts”. On the item of harmonization only intensity of extraction is necessary to address. After discussions of the defining of intensity methods are developed to compare the intensity of extraction in different countries. This item will be incorporated in ToR I in the coming years. An inventory is made of procedures and legislation concerning aggregate extraction and cultural heritage for each ICES member country. 4 | ICES WGEXT REPORT 2016 An inventory is made of the legal thresholds for an Environmental Impact Assessment for each ICES member country. Terms of reference G, H and J are completed. The other Terms of Reference will continue. New Terms of Reference are formulated on impacts of marine sediment extraction on fish and fisheries and on implications of marine spatial planning on marine sediment extraction.
