HomeRemote sensing’s contribution to evaluating eutrophication in marine and coastal waters evaluation of SeaWIFS data from 1997 to 1999 in the Skagerrak, Kattegat and North Sea
Publication metadata
The aim of this report is to examine whether estimates of the plant pigment chlorophyll-a from satellite data can support the evaluation of eutrophication in European marine and coastal waters. Satellite images are a good indicator of the occurrence of algal blooms in relation to eutrophication but overestimate true chlorophyll-a concentrations in open sea areas by 60-70% and even more in coastal waters. The report recommends using chlorophyll-a images from March to April/May as an indicator of eutrophication in the North Sea, Skagerrak and Kattegat since they reflect the magnitude of the spring bloom in these areas.
