The data and results of these efforts will further improve the assessment of potential impacts from the Navy including training and testing activities, installation construction (e.g. pile driving) and vessel-transiting activities as required under the Marine Mammal Protection Act and National Environmental Policy Act for Commander, U.S. Fleet Forces Command (USFF) and Commander, Navy Installations Command in the region. These data may also provide important baseline information for the assessment of potential future impacts from climate change or other anthropogenic activities.
