ORIGINAL REPORT, THURSDAY: Thanks to Jill for the photo. She asked about the red water along the shore south of Fauntleroy. Chances are that it’s the nontoxic algae bloom known as noctiluca, which has shown up time and again over the years – compare that photo to others we’ve published, such as 2014 and 2012. As explained by this state Department of Ecology webpage, noctiluca blooms are nontoxic.
MONDAY UPDATE: Thanks to Kersti Muul for turning up this new Ecology link confirming ongoing algae blooms.
