A decision support system to assist the sustainable management of navigation activities in the St. Lawrence River Estuary, Canada

摘要: We describe a decision support system that has been developed to inform management and planning in portion of the St. Lawrence Estuary Canada (covering Saguenay-St. Marine Park proposed Protected Area). The is composed spatiotemporal, georeferenced database, simulator (3MTSim) reproduces spatiotemporal movement marine mammals maritime traffic estuary, data post-processing tools can be used analyse output 3MTSim. 3MTSim allows users test different scenarios for (e.g., area closures, speed limits, regulations concerning observation mammals) order assess their effects on navigational patterns which may influence mammal exposure vessels. includes an individual-based model elaborated based existing telemetry fin, blue, beluga whales as well land-based theodolite tracking humpback minke whales. Observations recorded aboard research whale-watching vessels have provided spatial necessary estimate species' abundances distribution maps are initialise whale model. Different types vessels, including cargo ships commercial boats also modelled individually, using agent-based approach. boat represents decision-making process captains function environmental conditions, contextual setting, respective goals. An extensive database real-time available coupled with observations interviews, served elaboration In this paper, overview entire presented its effectiveness tool demonstrated via results from sample scenario-based simulations.
