How could state of the art ecosystem modelling support the HELCOM eutrophication assessment?


	Vivi Fleming (SYKE)
	The eutrophication status of the Baltic Sea is assessed using a quantitative indicator-based assessment. No single parameter or indicator alone is sufficient to evaluate overall eutrophication, and a set of HELCOM CORE indicators with agreed boundaries for Good Environmental Status (GES) has been agreed upon by HELCOM. Present levels of these indicators may be updated using monitoring data reported by the coastal countries. However, evidence for estimating boundaries for GES is hard to find in a sea with a long history of widely spread pollution. In this presentation, I will explain the HELCOM eutrophication assessment approach and provide insight to problems and information gaps that could be filled by combining state of the art modelling with a management perspective. I will also show examples on how modelling has been already used to improve the eutrophication assessment of the Baltic Sea.
