Diagram of Ocean Currents

The tides and currents of the Salish Sea directly affect our lives and all marine ecosystems.  Up and down, round and round, why do the waters move?

We will look at the physical factors that create the tides and currents that are such a part of our lives on Whidbey Island, the Salish Sea, and the entire planet.  What does mixed semi-diurnal mean, anyway?  What is the difference between a higher high tide and a lower high tide?  Why are low tides at night in the winter and during the day in the summer?  Why are beaches sandier in the summer and rockier in the winter? 

How does all this affect the behavior of salmon, seaweed, and nuclear power plants?  And how does all this affect me when I visit the beach, paddle a kayak, take a ferry, or try to balance an egg?

Tides wait for no man, but that means they are predictable.  How will the movement of water affect your property?  How do we predict tides in a practical way?  How does a storm change those predictions?  Should we use the dependability and energy of tides for power generation?   With visuals and discussions, we will be able to better understand these processes that create our tides, determine our coastline, and touch our lives.
