Definition
- Since 1991, NOAA's National Marine Mammal Laboratory Laboratory (NMML) in Seattle, Washington and Pacific Marine Environmental Laboratory (PMEL) in Newport, Oregon, have collaborated on a joint study to assess the potential of long-range acoustic monitoring of free-ranging populations of large cetaceans. NMML brings many years of experience in population stock assessment based on field observations, with supporting data on habitat, near-field acoustics and behavior. PMEL brings expertise in underwater acoustics and access to both the U.S. Navy's underwater SOund SUrveillance System ( SOSUS) and autonomous moored hydrophone recorders designed for long-term, deep-ocean deployment. This joint study has been largely funded through the Strategic Environmental Research and Development Program (SERDP), with additional support from the Office of Naval Research (ONR), NOAA's Environmental Services Data and Information Management (ESDIM) Program, NMML, and the NOAA VENTS program at PMEL. This powerful combination of SOSUS and autonomous moored hydrophone data has enabled PMEL researchers to record the low-frequency calls of blue and fin whales throughout the Pacific Ocean, and to identify regional differences in blue and fin whale vocalizations. Locating calling whales also enables PMEL to identify apparent seasonal shifts in whale distributions. Correlating these data with NMML current field observations and their extensive historical database of species distributions may help answer critical population and stock management questions.
