Annual oil rates in Common Guillemots (n >25 complete carcasses) in OSPAR area 8 (Eastern Southern Bight mainland coast Dutch contribution only) and 5-year running (arithmetic) mean oil rates since the late 1970s. The quality of the assessments over 2007/08-2010/11 and 2014/15 (but not 2012/13-13/14!) is low due to low sample size (few corpses). No oiled birds in 2013/14, relatively many in 2014/15.

Northern Gannets are passage migrants in Dutch coastal waters. Ship-based seabird surveys revealed that Gannets occur year-round in the Southern North Sea, a finding that has been supported by beached bird surveys. Most of the beached Gannets in The Netherlands were either oiled, or entangled in fishing gear. Typical patterns of oiling (birds seem...
