17974 Project Published / External 12848 Cetaceans - Passive Acoustics Project In Work This catalog contains acoustic recordings of cetaceans collected from areas within the Pacific Islands Region since 2006. In collaboration with researchers at the Scripps Institution of Oceanography and the PIFSC EOD, the Cetacean Research Program (CRP) currently uses bottom-mounted data recorders called High-frequency Acoustic Recording Package or HARPs - to conduct passive acoustic monitoring studies. The HARP dataloggers are moored to the sea bottom and remain there for an extended period of time (e.g., 6 mos. to 2 yr.). More than 25 species of cetaceans occur in U.S. Exclusive Economic Zone (EEZ) waters of the Pacific Ocean, including several listed as endangered under the Endangered Species Act, and depleted under the Marine Mammal Protection Act. The National Marine Fisheries Service (NMFS) is responsible for studying the populations of whales and dolphins within the U.S. EEZ waters of the Pacific Islands Region (PIR). A variety of information is needed in order to properly manage human effects on these populations and protect them from current or future depletion. Passive acoustics are useful for assessing temporal and spatial changes in the density and behavior of some animals, for augmenting visual surveys in finding animals and can provide important details regarding the acoustic environments that cetaceans live within.
