Underwater noise from ship traffic is one of the major threats to Puget Sound’s endangered Southern Resident orcas. It can interfere with the whales’ ability to communicate, navigate by echolocation and find the increasingly scarce salmon they prefer.

A recommendation from the orca recovery task force convened by Gov. Jay Inslee in 2018-19 is to reduce noise and disturbance from large vessels. Work is underway to develop a program called “Quiet Sound,” which will alert ships to the presence of whales so they can re-route or slow down.

It’s modeled after a program in British Columbia, called Echo. It’s voluntary, but used by most ship captains on their smartphones.

“The app is in the pockets of a lot of the mariners already,” said Seattle Port Comissioner Fred Felleman. He’s been pushing to get Quiet Sound up and running as soon as possible, because it’s especially needed at this time of year, when orcas follow salmon in to busier parts of Puget Sound.

“This is when the whales are in town and we have two new babies already born: J-57 and -58. And J-46 is about to give birth,” Felleman said. “So this is when we really want to be as protective as we can.”

The ports of Seattle and Tacoma have contributed $100,000 to get the program started. They estimate they need to raise another $400,000 to staff up and make the program fully operational.

John McCarthy is president of the Port of Tacoma Commission and co-chair of the Northwest Seaport Alliance. He spoke during a recent webinar on the status of Quiet Sound.

“While Echo has been a success and a model for us to consider, we have the opportunity to adapt and make sure we’re doing what’s right for the Puget Sound in Washington state,” McCarthy said.

Like Echo, Quiet Sound will be completely voluntary. And it will use the same smartphone app to communicate with mariners. But the sources of sighting data that feeds into it will be different, and the recommended speeds and detours near whales would be adjusted to local conditions and regulations.

The ports of Seattle and Tacoma say they have provided the startup funding. But, given the urgency around protecting the small population of Southern Resident orcas that remains, they’re hoping contributions from state, federal and private sources will make up the difference as soon as possible.

The latest official count of Southern Resident killer whales from the Center for Whale Research puts their number at 74, including the two recently born calves.

Shhh … A Quiet Sound Protects Orcas

Shhh … A Quiet Sound Protects Orcas

Maritime BlueShhh … A Quiet Sound Protects Orcas

November 9, 2020

The Orcas are back! The Southern Resident Killer Whales returned to Puget Sound with new babies in the pod. We all need to do our part to protect the Orcas while they are here.

Underwater noise poses a challenge for orcas, an endangered species that are culturally and economically important to our region. Orcas use sound to hunt for salmon. Underwater noise impacts the killer whale’s ability to hunt, communicate, navigate, and avoid danger. That noise in Puget Sound can come from a variety of sources, including (but not limited to) small and large recreational boats and all sizes of commercial vessels.

Quieting the sound

In response to Governor Inslee’s Orca Task Force recommendations, the Port of Seattle partnered with the Port of Tacoma, the Northwest Seaport Alliance (NWSA), and other agencies, tribes and organizations to develop a blueprint for a program to reduce impacts to orcas from large commercial vessels. The Quiet Sound Program is a collaborative initiative that will — among other things — improve the reporting of whale sightings and get that information to the pilots of large vessels, so they can take action to slow down or move away from orcas.

The goal is to reduce the exposure of orcas to vessels in Puget Sound, contributing to their recovery by reducing stress levels and helping them function and find food. Quiet Sound will rely on these elements to help protect orcas:

  1. An effective alert system that can locate orcas. Non-profit organizations, professional mariners, and others are engaged to be the eyes (and ears) throughout the Salish Sea
  2. A communication link between the spotters and the maritime industry. It’s a way to get whale data and location to vessels that are willing to make a change to their speed or course
  3. Engaged, committed, and voluntary participation from large commercial vessel operators
  4. Keeping track of innovations that can be used to retrofit existing vessels and design new quieter vessels
  5.  Adaptive management to ensure Quiet Sound is achieving its goals

Port protects orcas

According to Sandra Kilroy, Director of Maritime Environment and Sustainability at the Port, this program is a logical addition to what’s been a longstanding priority at the Port.

“The Port of Seattle over the last couple of decades has really been leading on environmental issues. The community values, the environment, and quality of life are why many of us choose to live here. The Port is reflecting those community values, so addressing underwater noise and its impact on killer whales is a natural next step.” 

Before this program, the Port of Seattle was already actively involved in numerous efforts to protect our beloved Southern Resident Killer Whales by:

  • Holding an underwater noise conference on October 3, 2019. The Port of Seattle, Port of Tacoma, NWSA, Washington State Ferries, NOAA, and the Puget Sound Partnership co-convened a workshop of a broad range of experts and interests to identify ways to reduce underwater noise in an effort to support a recovery of the endangered population of Southern Resident killer whales.  Learn more 
  • Supporting the implementation of the Whale Report Alert System (WRAS) developed by OceanWise, the BC Cetacean Sightings Network, Vancouver Aquarium, and the ECHO program. The alert system is a cell-phone based application that is used to inform commercial mariners when whales are nearby.  Members of the public can send whale sighting reports via the WhaleReport app (Apple, Android).
  • Developing clear signage at the Port’s six marinas to educate boaters about how to protect the orcas
