Cailene Gunn is a junior scientist for the Coastal Sciences Division of the Pacific Northwest National Laboratory, located at the Marine Sciences Laboratory in Sequim, WA. Cailene’s work is largely focused on biogeochemical cycling, and coastal ecology and restoration. Her research experience includes greenhouse gas assessments of forested and wetland ecosystems, restoration of eelgrass populations and tidal marshes, large-scale carbon assessments in the Pacific Northwest, and long-term ecosystem monitoring through field research and GIS mapping. Recently she has been involved with work assessing environmental impacts of marine renewable energy deployments through the Triton Initiative and Tethys. Cailene is interested in outreach and education and has worked on the ECO-Citizens program which aims to involve local communities with water quality assessments through water color measurements.
