About this Briefing

In recent years, HABs – a rapid overgrowth of toxin-producing microscopic algae – have been making headlines due to their increasing frequency and intensity. This year marks the fourth consecutive year of significant HAB-related marine mammal mortality in Southern California, from San Diego to Santa Barbara1. Given the widespread effects of HABs, there is an urgent need to understand the potential consequences of their presence to water quality, marine ecosystems, wildlife, and human health and well being. This briefing is an opportunity to learn from scientific experts about our current understanding of how HABs have impacted California’s ocean resources and wildlife, current monitoring efforts, and emerging findings from recent bloom events.
