As we head into another season of harmful algal blooms, we are focusing this webinar on cyanobacteria in the context of global climate change, including nitrate, reduced ice cover, and increased temperatures and light. Tune in as we feature 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.

This edition of the Algal Bloom Action Team featured Nicole Wagner, Assistant Professor at Oakland University, who explores 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.

The webinar start with a brief presentation of the FY24 funding opportunities, including the priorities in each RFP, budget requirements, and time for questions. The second portion of the webinar will be topic-specific breakout rooms for researchers to identify potential collaborators. USGS scientists are being invited to attend these sessions to briefly describe their work and interests in collaborating with university researchers.

USGS in cooperation with the National Institutes of Water Resources (NIWR) has released their annual request for proposals under its National Competitive Grants Program (104G, PFAS and Aquatic Invasive Species). Any investigator at an institution of higher learning is eligible to apply for these grants with research that focuses on priorities of regional and national importance. Application must be through the Water Resources Research Institute (WRRI) in their State or Territory. The RFP has been released with an application deadline in late April 2023 – exact date will vary by your state institute. For more information about the funding opportunities.

WRRIs from across the US are organizing a joint webinar on March 9th, 2023 at 2 p.m. Eastern Time that focuses on the National Competitive Grants RFPs. We will discuss the full proposal process and funding priorities and include an opportunity for researchers to ask questions. In addition, researchers will be able to identify potential collaborators in topic specific breakouts. Also see USGS information or information for IWRRC.

Predicting when and where conditions are ripe for harmful algal blooms would ideally reduce the bloom’s impact on water quality and mitigation costs. So, why is harmful algal bloom prediction so complex?

This webinar featured presentations from Justin Chaffin, Senior Researcher and Research Coordinator at Stone Laboratory at The Ohio State University, and Katie Foreman, Physical Scientist at the US EPA. The discussion focused on their research on the ecology and physiology of harmful algal blooms and how this work can be used to help solve the prediction puzzle!
