Science Seminars
Water and Land Resources Division
The Science Section sponsors semiannual, half day Science Seminars in which visiting lecturers and King County staff present recent findings from their environmental monitoring programs. The Science Seminar provides an opportunity for sharing information between staff and with the public, and also allows staff to gain public speaking experience in front of professional peers. Science Seminars are open to all interested environmental science professionals and the public. For more information about Science Seminars, please contact Kate O’Laughlin.
After each seminar, the presentation materials are made available below, typically as Acrobat PDF files.
