On December 3rd, 2025, the Algal Bloom Action Team hosted a webinar focusing on the use of knowledge guided machine learning (KGML) to advance water quality modeling. This webinar featured the work of Dr. Paul Hanson, a Distinguished Research Professor and ecosystems ecologist at the University of Wisconsin–Madison, Center for Limnology.
Harmful Algal Bloom 2025 Annual Symposium Recap
The Algal Bloom Action Team’s held its fifth Virtual Harmful Algal Bloom Research Symposium on January 9, 2025. We discussed how to predict, prevent, and treat harmful algal blooms (HABs), as well as the human impact of HABs.
ABAT Webinar Recording: Minnesota’s Cyanobacteria Problem
On August 6th, 2025, the Algal Bloom Action Team hosted a webinar to discuss the work being done on cyanobacterial harmful algal blooms (cHABs) in Minnesota. Cody Sheik, microbial ecologist, talks about the process of tracking and managing cHABs.
ABAT Webinar Recording: Lake Physics and Social Perspectives on Freshwater Harmful Algal Blooms
On August 2nd, 2025, the Algal Bloom Action Team hosted a webinar featuring two speakers who discussed how lake physics and internal nutrient loading can create toxic blooms, and how constituents are understanding and assessing HAB risk.
ABAT Webinar Recording: A Look at Cyanobacteria
On March 5th, 2025, the Algal Bloom Action Team hosted a webinar featuring the work of Rick Stumpf, Oceanographer with the NOAA National Centers for Coastal Ocean Science, who discussed cyanobacteria in the Great Lakes and other large lakes from satellite and Rebecca North, Associate Professor with the University of Missouri, who discussed her work studying winter cyanobacteria.
ABAT Webinar Recording: Resource Stoichiometry and Nutrient Influences on Cyanobacteria
On August 7th, 2024, the Algal Bloom Action Team hosted a webinar with Nicole Wagner, Assistant Professor at Oakland University, exploring how anthropogenic nutrient enrichment and imbalances of nitrogen to phosphorus ratios affects the eco-physiology and cyanotoxin concentration and quotas in cyanobacteria bloom-forming genera. This topic was explored at different scales from manipulative controlled laboratory experiments to whole ecosystem high-frequency monitoring.
ABAT Webinar Recording: Cyanobacteria in the Context of Climate Change
On June 5th, 2024, the Algal Bloom Action Team hosted a webinar focusing on cyanobacteria in the context of global climate change, including nitrate, reduced ice cover, and increased temperatures and light. This webinar featured the work of Rebecca North, Associate Professor at the University of Missouri’s School of Natural Resources and Silvia Newell, Director of Michigan Sea Grant and Professor at the University of Michigan School for Environment and Sustainability.
ABAT Webinar Recording: Understanding Microcystis Dynamics from Dry to Wet Years
On April 3rd, 2024, the Algal Bloom Action Team hosted a webinar featuring Ellen Preece, Senior Scientist for the California Department of Water Resources. Dr. Preece will share her research on microcystin dynamics during drought and record wet years in the Sacramento-San Joaquin Delta in California.
ABAT Webinar Recording: Unraveling the Mysteries of Harmful Algal Blooms
On February 7th, 2024, the Algal Bloom Action Team hosted a webinar featuring two presentations – Jen Wisecaver, associate professor at Purdue University, who discussed extreme diversity and cryptic species in Prymnesium parvum and Barry Rosen, professor at Florida Gulf Coast University, who discussed the secrets of freshwater cyanobacteria blooms.
Harmful Algal Bloom 2024 Annual Symposium Recap
The Algal Bloom Action Team’s held its fourth Virtual Harmful Algal Bloom Research Symposium on January 4th, 2024. We discussed the monitoring and treatment of harmful algal blooms (HABs), as well as outreach and communication about HABs. This year’s symposium also featured a presentation from the National Oceanic and Atmospheric Administration (NOAA) ocean acidification program about their work assessing freshwater acidification.
