Scene in Edmonds: Sea foam at sunrise

Photo taken at sunrise Wednesday by Sharon O’Brien.

According to, “lots of tiny bubbles clustered together along the edge of the tide is sea foam. Thick sea foams are commonly caused by algae blooms. When big algae bloom and die off shore, large amounts of decaying algal materials frequently wash up. As the wave churns up the biological debris, foam develops.” Adds “Most sea foam is not harmful to humans and is often an indication of a productive ocean ecosystem.”

  1. Thank you for the unique photo, Sharon. And to My Edmonds News for the explanation of the foam.
