Project Objectives
Conduct visual line-transect surveys and passive acoustic monitoring for cetaceans, and other marine mammals, to determine species occurrence, and to estimate density within Navy’s testing range. Acoustic monitoring devices will be deployed during the vessel based survey, and long-term passive acoustic hydrophones will be monitored for year-round detection of rare and/or cryptic cetacean species.
