Odontocete occurrence in relation to changes in oceanography at a remote equatorial Pacific seamount
Abstract Seamounts are considered hot spots of biodiversity and can aggregate pelagic predators and their prey. Passive acoustic monitoring was conducted over 3 mo in 2012 to document the occurrence of odontocetes near a seamount chain in the central equatorial Pacific in relation to oceanographic c...
