A cetacean sighting survey was conducted as a component of the LAPE project Ecosystem survey, conducted 26 April – 22 May 2006. The survey was conducted from the Irish research vessel Celtic Explorer which is primarily specialized for hydroacoustic surveying but is fully equipped for trawling as well. The sighting platform (crows-nest) was approximately 16 m above the water.
The sighting survey used the same stratified transect design as the acoustic survey. Procedures were based on those used in 2004 with minor modifications to account for the differences in the vessel and other planned activities.
