GLRI-Funded Study Identifies Overwintering Cyanobacteria Cells as Algae Bloom Contributors

(Nov. 28, 2018) A University of Michigan study funded by the GLRI has concluded that cyanobacteria cells that survive the winter in lake-bottom sediments contribute to annual algae blooms in the western Lake Erie basin.

The findings advance scientists’ understanding of the basic biology driving the annual summer blooms, which are both an unsightly nuisance and a potential public health hazard. In addition, the work identifies a mechanism to explain the rapid increase in Lake Erie bloom size and spatial extent in early summer.
