Conference Theme

Please join us in beautiful Orange Beach, Alabama, for the 10th US Symposium on Harmful Algae. We encourage everyone who works on issues associated with harmful algal blooms to attend the only national conference focused exclusively on HABs. Whether your focus is freshwater or marine systems, microalgae or macroalgae, basic research and monitoring, or policy and management, there will be opportunities for you to learn and discuss all facets of HAB studies. Students, established HAB folks, managers and scientists from NGOs, academic institutions, and local, state and federal agencies are encouraged to join us. Sign up for HABs workshops preceding the meeting.  Groups interested in hosting the 11th US HAB Symposium in 2021 are encouraged to email Mindy Richlen or visit this website.
