Description

Biotic and abiotic factors influencing blooms in reservoirs, aquaculture ponds, and other systems.

Using data we collected in collaboration with scientists at the Alabama Department of Environmental Management, we recently built simple models aimed at forecasting blooms of phytoplankton and cyanobacteria in freshwater ponds, reservoirs, and lakes.  Water resource managers, lake owners, and researchers can learn more about it:
