The research project AMORE-II adresses eutrophication processes in Belgian coastal waters. Based upon knowledge gained during the projects AMORE-I (1997-2001) and IZEUT (2000-2001), research will further focus on establishing quantitative and qualitative links between nutrients (N, P, Si), spreading of high biomass blooms of the colony-forming Haptophycea Phaeocystis, the diatom Guinardia delicatula and the dinoflagellate Noctiluca. In support to governmental policy, the overall objective of AMORE II is to provide new ecological knowledge and an upgraded version of the existing three-dimensional ecological model 3D-MIRO&CO.
