Every fall and winter, the last 74 endangered Southern Resident killer whales (SRKWs) make Admiralty Inlet and North Puget Sound their dining and resting room, hunting salmon, socializing, and navigating the waters. Unfortunately, underwater noise from large commercial vessels makes that job harder—masking their communication and making salmon hunting more difficult.
That’s why Quiet Sound, a coalition of federal, state, tribal, port, maritime industry, scientists, and NGOs, is once again launching its seasonal voluntary slowdown for large commercial ships in this region. Since its start in 2022, the slowdown has measurably reduced underwater noise and helped improve habitat quality for these whales.
When & Where
The 2025–26 slowdown runs September 2, 2025 to January 11, 2026*, covering inbound and outbound shipping lanes between Pt. Hudson, Admiralty Head, Randall Pt., Mukilteo Lighthouse, Apple Cove Pt., and Edwards Pt. (Hood Canal is excluded). It kicks in the day after SRKWs are confirmed in the zone anytime after September 2.
Speed Goals
14.5 knots or less for vehicle carriers, cruise ships, and container vessels
11 knots or less for general cargo, bulkers, and tankers
Fishing and recreational vessels aren’t included, but every mariner can help by being alert for whales.
Benefits for Mariners
Participants can track fleet participation rates for ESG reporting, qualify for Green Marine certification criteria, receive recognition certificates, and even be highlighted on Quiet Sound’s website or nominated for regional environmental awards.
Get Involved
Mariners are encouraged to:
Sign up for the Whale Report Alert System (WRAS) to get text alerts when whales are nearby
Take the Whales in Our Waters online training for safe vessel-whale interactions
Report sightings to the U.S. Coast Guard Cetacean Desk, Orca Network, or Canadian Coast Guard (if applicable)
By slowing down when it’s safe and feasible, the maritime community can make a real difference for one of the Pacific Northwest’s most iconic and endangered species.
