The RBINS-EMBRC project aims to develop a centrally managed ‘Artificial Hard Substrate Garden (AHGS)’, to provide a flexible in-situ offshore test facility as an EMBRC service pillar to researchers and industry. This test facility will support research on the effects of man-made structures (renewable energy devices, mariculture installations, coastal defense structures, etc.) on the marine environment. Based on suggestions from both the scientific community and industrial partners at annual meetings, continuous optimization of the installations will be actively pursued. Along with the integration of the currently scattered project-based AHSG components into a centralized system, additional services by RBINS (scientific diving; Marine Taxonomic Reference Centre; etc.) will be aligned to offer a high-quality EMBRC service with respect to artificial hard substrate ecology.
