Eutrophication assessment using remotely sensed and in situ chlorophyll-a data : KPP efficiente monitoring 2013 : eutrophication

National marine environmental monitoring is carried out for multiple purposes. The comparison between chlorophyll-a based on remote sensing and the in situ data in the context of a typical OSPAR eutrophication assessment shows that both sources of information have their strengths and limitations. Possible biases notwithstanding, the spatial coverage of the remote sensing data is providing amore accurate way of estimating regional statistical properties of the ecosystem compared to point-based (station-wise) assessments. The ultimate recommendation for RWS is to start implementing ocean colour remote sensing as a baseline data source in its monitoring strategy from 2014 onward.
