- NAVAREA IV General / Hazards To Navigation / Obstructions Location: 39-37.44N 072-28.44W The Wildlife Conservation Society submitted a Notice to Mariners regarding planned acoustic monitoring work near the Hudson Canyon. The project involves deploying four small, fully submerged acoustic recorders at four sites near the northern end of Hudson Canyon to detect vocalizing cetacean species and characterize the ambient underwater noise environment. The equipment consists of compact acoustic recording units suspended approximately two meters above the seafloor between an anchor and a small sub-surface float. The design has no surface expression and uses an acoustic release system intended to leave no equipment or mooring on the seafloor after recovery. The listed monitoring sites are located at approximately 39°44'52.02" N, 072°25'6.72" W; 39°37'26.33" N, 072°28'26.67" W; 39°36'47.57" N, 072°17'9.68" W; and 39°28'44.31" N, 072°32'56.1" W. Initial deployment is planned for August 26, 2026, with retrieval and redeployment anticipated in October or November. Work will occur during daylight hours, generally between 7:00 a.m. and 7:00 p.m. Operations will use a small research vessel, approximately 6 to 10 meters in length, along with acoustic receivers, anchors, rope, sub-surface buoys, and related deployment equipment. The recorders and floats will be placed approximately 80 meters below the surface, with no surface equipment, which is intended to avoid interference with vessel traffic. Marine radio channel 16 is listed for communications, and no disposal site is associated with the activity. Valid 2026-08-24 to 2026-11-30. USCG Northeast District Local Notice to Mariners 45/2026
