San Francisco Baykeeper‘s field science team investigated reports to the organization’s pollution hotline and confirmed reddish brown (“tea colored”) waters in the Berkeley marina, and subsequently along the shores of Emeryville, Berkeley, and Albany. Following preliminary analyses, Baykeeper scientists suspect this algal bloom is likely caused by an outbreak of the algae Heterosigma akashiwo. Last August, a harmful bloom of the same algae caused a red tide that spread across the Bay, resulting in an unprecedented fish kill event.
