What Happens When the Bar Closes? — The Sandbar, That Is
September 6, 7–8:30pm — Public Talk at Sonoma Land Trust, Level 1
September 15, 10am–2pm Russian River Estuary Walk — Members Only, Level 3
Many estuaries are characterized by intermittent closure, which is when a sandbar closes the mouth and separates a coastal lagoon from the ocean. In the basin behind the sand barrier, water levels may rise or fall and water quality extremes typically develop. Professor John Largier of Bodega Marine Lab will talk about the Estero Americano and other estuaries as he shares his research with us. This presentation will be followed by an in-person exploration of the Russian River estuary.
