$10 admission ($5 PTMSC members)
November’s lecturer, Parker MacCready, is Professor of Oceanography in the University of Washington’s College of the Environment. He has worked for the past 15 years studying tidal currents and general circulation of Pacific Ocean waters, including a number of projects in Puget Sound and the San Juans. His work combines detailed field studies with realistic computer models, trying to discover the processes that turn the energy of tides, winds, and rivers into the circulation patterns that control the biological productivity of the Puget Sound estuary.
In this talk he will explore the tides in Puget Sound, from their astronomical origin to the the extraordinary fronts and eddies so apparent to boaters. This then leads to consideration of the turbulent mixing these eddies cause, and how they drive a large, persistent current of deep Pacific water though the Sound. It is this circulation, many times greater than that of all our rivers, that brings nutrients which feed the abundant growth of phytoplankton in our waters.
The Future of Oceans Lecture Series: With more than seven-tenths of the planet’s surface covered in salt water, the future health of our oceans is critical. Join the PTMSC for a series of five lectures on The Future of Oceans the first Sunday of every month, from October through March, (except January due to holidays) to learn about topics such as El Niño, the tides and eddies in Puget Sound, what’s beneath the Salish Sea, Arctic images, and ocean acidification. All lectures are at Fort Worden and the series is provided by the generous support of the Darrow family.
