Outline • Stakeholder needs • The Ferrybox network in Norwegian waters and additional monitoring activities • Data dissemination and web portals • Conclusions
Stakeholder needs • Knowledge on supply of pollutants and undesired species • Concentration and transport within the norwegian waters • Monitoring of algal blooms, eutrophication and particles • Air pollution • Supply of pollutants from Oil and gas industry
Stakeholder needs I • Discharges and transport of pollutants to norwegian waters from all possible sources • From land and rivers • From air national and international • Long transported • Oil and gas industry • Shiptrafik • Natural discharges from the bottom • Suspension/Resuspension of sediments
Stakeholder needs II • Long term monitoring environment quality for coastal areas (WFD) • Algal concentrations and changes in species composition • Nutrients • Soft and hardbottom fauna • hydrography
