Regional Science Consortium Researching Harmful Algal Blooms
If you've noticed large buoys or boats out on the bayfront and wondered what they were, you're not alone. The Regional Science Consortium is collaborating with Princeton Hydro on a research project funded by the U.S. Army Corps of Engineers to study ways to control harmful algal blooms. Dr. Jeanette Schnars, the Executive Director of the Regional Science Consortium, explained the goal of the research."We are researching different ways to control blue-green algae, which creates harmful algal blooms and releases toxins," Dr. Schnars said.The project aims to identify potential techniques for controlling harmful algal blooms in Presque Isle Bay.Schnars explained that people may notice circular floats in the water near Perry's Landing and Liberty Park. Those floats are part of the testing process."You might see a circular float, almost like a hula hoop, that is out in the bay, near Perry's Landing and Liberty Park area, and those limn corrals go all the way to the bottom. And what we will do are some treatments within the limn corral in the bottom," Schnars said.After samples are collected, they are brought back to the laboratory at the Tom Ridge Environmental Center for analysis."A lot of those samples are coming back here. We are going to test them for the harmful algal bloom toxins before, during, and after, and see how effective the testing was," Schnars said.Sarah Magyan, an aquatic biologist with the Regional Science Consortium, explained that the team also collects samples from locations throughout the region."We pull samples every week from 30 different sites, and then we bring those back here, we preserve them and run them through the ELISA test," Magyan said.Schnars said researchers hope the results will help them develop effective ways to reduce harmful algal blooms in the future."If we can do some treatments over space and time in upcoming seasons, we may be able to reduce the number of harmful algal blooms we have in this area," Schnars said.The research is also important for public and animal safety. Magyan explained that toxins produced by certain algae can affect the skin, nervous system or liver.While toxin levels may be low for people, she emphasized the importance of protecting pets that swim in local waterways."Toxins can either be skin toxins, nerve toxins, or liver toxins. While we have low levels for people, it is important that we are keeping our pets safe because we recreate with our animals in the water, and we see hundreds and hundreds of dogs on Presque Isle and the rest of the shoreline," Magyan said.Testing began in September, and Schnars said researchers expect to conduct at least another six to eight weeks of testing to better understand the effectiveness of the treatments.
