Mariners are advised that the National Oceanic and Atmospheric Administration will conduct hydrographic survey operations offshore of the New York Traffic Separation Scheme from September 20, 2026, through October 31, 2026. Operations are scheduled to occur 24 hours per day within an area bounded by approximate positions 39-57.50N 073-30.21W; 40-17.18N 073-41.75W; 40-33.39N 073-28.31W; and 40-24.97N 072-55.45W.

Survey operations will involve the use of a Moving Vessel Profiler, an underwater towfish deployed approximately 30 to 50 meters astern of the survey vessel. Mariners transiting the area are requested to exercise caution, maintain a safe passing distance, and avoid impeding survey operations. Vessels involved in the operation may be contacted on VHF-FM channels 16 and 13.
