Cyanobacteria have the potential to produce harmful toxins which can cause adverse health effects in humans and animals. Monitoring tools are needed to assess environmental conditions and stop blooms in their nascent stages. This workshop will provide a comprehensive introduction to algae HAB monitoring, from the reservoir to the lab. Participants will gain practical skills in the use of online multi-parameter systems, microscopic identification, and data collection and visualization. The workshop will begin with introductions and a brief PowerPoint overview of each of the technologies. Next, we'll turn to the instruments and run samples furnished by workshop attendees. 

Three samples will be selected to illustrate the implications of variables like sampling methodology, preservation, location, and settings on FlowCam imagery and data. For each sample, we’ll highlight a different FlowCam theme and use image recognition to identify dominant organisms. Each sample will be discussed as a group, with participants encouraged to ask questions and converse regarding the technology's benefits and limitations. Throughout the workshop, we'll point out similarities and differences between flow-through imaging and traditional microscopy, as well as basic plankton identification using semi-automated techniques. 

Samples of cyanobacteria in various concentrations will be analyzed to illustrate the hardware and software of the AlgaeTracker. Participants will learn how to calibrate field data to lab results and verify the accuracy of live readings obtained from samples. Throughout the workshop, attention will be given to potential challenges of fluorescence-based readings, with discussion focusing on potential and actual solutions. Tips for easy field deployment, maintenance, and data sharing will be discussed with group participation encouraged. 

We’ll conclude by summarizing takeaways from the workshop and, if time allows, play an interactive game incorporating FlowCam and AlgaeTracker images and data to test participants’ knowledge.
