Summer distribution and relative abundance of cetaceans off the west coast of Ireland. Biology and Environment
From May to September 2004 a survey of cetacean distribution and relative abundance was conducted on board a ‘ship of opportunity’ * a vessel used as a survey platform but not chartered for this purpose*off the west coast of Ireland. In total, 508 hours of survey effort were completed, with 304.2 ho...
