This week marks the end of our summer algae monitoring program in #SFBay for 2024. In August, our sampling confirmed a bloom of Heterosigma akashiwo—the species that proliferated into devastating blooms in 2022 & 2023—in #Alameda. Luckily, it dissipated within a couple of weeks.

Our team also found elevated Chaetoceros algae in the Bay, which aren't toxic but can cause fish kills. We're keeping an eye on the algae with our partners at NOAA.

Pictured here are microscope closeups of Bay algae from our sampling: Chaetoceros (1st slide) and Heterosigma akashiwo (2nd slide) -- aren't they pretty??

Harmful Algae Bloom Detected in Alameda - San Francisco Baykeeper

Late last week, our community science monitoring program detected a harmful algae bloom (HAB) of Heterosigma akashiwo at Seaplane Lagoon and Encinal Beach in Alameda. H. akashiwo is the same species of algae that produced widespread blooms in 2022 and 2023, causing massive fish die-offs. We have one unconfirmed report of a localized bloom on

Algal Blooms Love Heat Waves. When Is Bay Area Swimming Dangerous for Humans and Pets? | KQED

As California continues to experience heat waves this summer, officials warn people about harmful algal blooms in lakes, rivers and streams that “can pose a threat to people and pets.”
