Modeling Vertical Migration Of Cyanobacteria And Zooplankton, Corina Christina Mae Overman Aug 2019

Modeling Vertical Migration Of Cyanobacteria And Zooplankton, Corina Christina Mae Overman

Dissertations and Theses

Cyanobacteria, also known as blue-green algae, often cause harmful algal blooms and release toxic substances that can harm humans and other animals. Accurately modeling these phytoplankton is a step towards predicting, preventing, and controlling such blooms. Cyanobacteria and zooplankton species are known to migrate vertically in the water column on a daily cycle. Capturing this behavior is one aspect of correctly modeling their dynamics. Here, several models of cyanobacteria vertical movement were tested in proof-of-concept models before being applied to data from field studies. These models included both continuum and particle-tracking frameworks. Four continuum-framework models of cyanobacteria vertical migration were ...
