Project Description

This project uses a network of underwater microphones to record marine mammals throughout U.S. and Mexican waters in the Gulf of Mexico and gather information on their location and density throughout the year. The data from this comprehensive and long-term passive acoustic monitoring program will be used to identify the conditions that could be driving seasonal, annual, and decadal trends in the abundance of marine mammals, where they are located, and their aggregation density. This project will complement existing vessel-based surveys and expand on prior passive acoustic monitoring in the region. This project is also coordinated with the Reduce Impacts of Anthropogenic Noise on Cetaceans project supported by the Deepwater Horizon Natural Resources Damage Assessment Trustees.
