The Navy completed its fourth week of real-time sound monitoring at Naval Air Station (NAS) Whidbey Island as directed by the National Defense Authorization Act (NDAA) for Fiscal Year 2020 (FY20).

Flight activity was monitored at 11 sites in proximity to Ault Field and Outlying Landing Field (OLF) Coupeville for seven consecutive days from Sunday, Aug. 8 through Saturday, Aug. 14. Data also continues to be collected in the Olympic National Park at a 12th site.

The week of monitoring included a typical range of high, moderate, and low-levels of flight activity.

The information will be available to the public once the yearlong monitoring effort is complete and the Navy has submitted the final report to Congress.
