This report presents data on use by seals tracked from the Netherlands of a zone of the North Sea off the east coast of the UK, the East Anglia Zone, where it is proposed to develop offshore windfarms. For this report, three areas of interest are distinguished within the East Anglia Zone: East Anglia THREE Offshore Windfarm (East Anglia THREE); East Anglia FOUR Offshore Windfarm (East Anglia FOUR) and the combined cable corridor for both projects. In the Netherlands, seals have been tracked from two Natura2000 areas: the Wadden Sea to the north and the Delta region to the south. Approval was sought from current clients of IMARES to incorporate data from seal research they have sponsored. All clients supported sharing of the data. Of 273 harbour seals fitted with trackers in the Netherlands between 1998 and 2013, ten came within 20km of an East Anglia area of interest and seven of those entered an area of interest. Of 77 grey seals fitted with trackers in the Netherlands, six came within 20km of an East Anglia area of interest and four of those entered an area of interest. Of the seals that entered an East Anglia area of interest, all but one probably spent >2% of their time-at-sea within that area. The exception was a harbour seal tracked from the Dutch Delta region (Zeeland) in 2007, which spent at least 2% and up to 17% of its time-at-sea within an area of interest.
