There is a really cool phenomenon called Redtide which is when a huge concentration of algae bloom takes place causing a discoloration in the water. The phytoplankton called Lingulodinium polyedrum contain photosynthetic pigments causing the Ocean waves near Pacifica and Linda Mar to turn a neon blue. The color is the most obvious when there is a lot of movement, so it mainly shows up during the waves. Not sure how long this will last, but it started occurring last week. Unfortunately, it is not as obvious with the human eye but it does look really cool in photos. These were done with around a 2 second exposure.
