FY2024 104G Webinar for Perspective Applicants

In anticipation of the release of the FY24 RFPs for 104G General, AIS, and PFAS nation competitions, the Great Lakes region is once again organizing a webinar for prospective applicants in these programs. The webinar will not be region-specific, however, and is meant for a nationwide audience of university researchers, potential USGS collaborators, and water center/institute staff.

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.

Short-Term Dynamics and Long-Term Trajectories of Algal Blooms in Lakes

Understanding algal blooms’ dynamics is essential for ecosystem and human health. While there’s been a hypothesis of climate-driven bloom intensification, U.S. lake data showed it’s not widespread. Early warning indicators of declining resilience may predict severe blooms in some cases, especially when significant ecosystem changes occur. This webinar featured Dr. Grace Wilkinson of the University of Wisconsin-Madison, who explored these complicated dynamics.
