About 40 volunteers participated in a dock fouling event near Olympia to document marine life accumulating on floating infrastructure. Participants uploaded their findings to the citizen-science website iNaturalist to support broader research.
Why it matters
The event aims to help the local community appreciate the diversity of marine organisms present on human-made structures. Understanding these local ecosystems helps residents gain a better perspective on the underwater environment.
The event brought together 40 volunteers to document marine life that settles on floating docks. Participants sought to identify creatures such as the giant rainbow nudibranch, which can grow up to one foot long.
The players
iNaturalist
This is a global citizen science data platform where users record and share observations of biodiversity.
The details
Participants lay on floating docks to observe marine life directly below the surface, recording their findings online. This activity highlights the complex ecosystem that develops on artificial surfaces like marinas in the Puget Sound area.
Timeline
A major fish farm failure released 250,000 non-native Atlantic salmon in 2017.
Ghader Alrashid observed her first sea star in 2025.
The volunteer dock fouling event took place in October 2026.
Culture Shift
The study of dock organisms provides a baseline for understanding bio-fouling in areas where Washington state's regulation of copper-based anti-fouling paint remains a subject of ongoing debate. This shift reflects a move toward citizen-led monitoring of local coastal health.
Residents can participate in future dock observation events to contribute directly to local marine databases. These efforts help citizens identify various organisms, such as nudibranchs, living in their immediate coastal environment.
The takeaway
Citizen science initiatives allow residents to become active observers of the marine life thriving on local infrastructure. By recording these organisms, volunteers provide essential data that helps track the health of coastal environments.
