About the project
As people from many communities return to the revitalized St. Louis River Estuary, harmful algal blooms have recently been confirmed within the estuary and western Lake Superior, with predicted warming temperatures and more frequent and intense rain events threatening to exacerbate these blooms. Very little is known about the causes of these toxic cyanobacterial blooms and degraded algal communities, or their relationship to hypoxic events. Without this understanding, estuary water quality stewards cannot build an effective early warning system for cyanobacterial blooms nor mitigate estuary stressors. This project aims to characterize estuary nutrient and phytoplankton dynamics at the headwaters of Lake Superior as a foundation for a collaborative strategy for future monitoring and action.
