Volunteers gathered at a marina near Olympia in October 2026 for a dock fouling event to document local marine life. Participants observed organisms accumulating on floating docks and shared their findings on the iNaturalist platform.
Why it matters
Understanding the marine organisms that thrive on local infrastructure helps residents appreciate the ecological diversity of the Puget Sound. This initiative encourages citizens to document biodiversity that is often overlooked in daily life.
The event drew 40 volunteers to observe marine life, including giant rainbow nudibranchs that reach lengths of one foot. These efforts document regional biodiversity following a 2017 incident where 250,000 non-native Atlantic salmon were released from a failed fish farm in Skagit County.
The players
iNaturalist
A global citizen science data platform used by researchers and the public to record and share biodiversity observations.
Washington State
The state government responsible for regulating environmental protections and the use of anti-fouling paints on marine vessels.
The details
Participants engage in dock fouling by lying on floating docks to observe organisms living just below the water line. This citizen-science effort tracks the health and variety of species residing on human-made structures. The data collected provides insight into the marine ecosystem as the state continues to evaluate its stance on using copper-based anti-fouling paint on boat hulls.
Timeline
A major fish farm failure released 250,000 salmon in 2017.
The dock fouling volunteer event took place on a Sunday in October 2026.
The Home Front
This community-led observation effort follows the state's decision to indefinitely postpone a ban on copper-based boat paints. The ongoing use of these materials in local waters continues to influence the bio-fouling patterns seen on private and commercial floating structures.
Residents near the water can contribute to regional research by documenting the marine life they observe on their own docks or local marinas. Check the iNaturalist platform to see what species have been recently identified in your specific waterfront area.
The takeaway
Citizen science efforts like Docktober help locals better understand the complex marine life sharing our harbor infrastructure. Take a moment to observe the organisms on your local docks and record your findings to help build a clearer picture of the regional ecosystem.
