Seabirds & offshore wind farms: Monitoring results 2009
In 2009, we refined the statistical set-up for the assessment of displacement effects on seabirds by wind farms in the Belgian part of the North Sea, more precisely at the Thorntonbank and Bligh Bank. The observed seabird densities were modelled through quasilikelihood estimation. The resulting mode...
