Title: Bloom today, Dead Zone tomorrow? The evolution of hypoxia in a hypereutrophic coastal embayment
Abstract: While representing only 7% of the surface area and 1.4% of the volume of Lake Michigan, Green Bay receives approximately one-third of the total nutrient loading within the entire Lake Michigan basin. Hypereutrophic conditions have been a persistent feature of the Bay throughout most of the last century, resulting in wide-spread seasonal hypoxia. Variability in the extent and duration of hypoxia results from a combination of thermal stratification, oxygen consumption in deeper waters of the bay, and estuarine-like physical forcing mechanisms. We are developing a set of linked models of watershed loading, biogeochemical cycling, and hydrodynamics that are designed to identify and assess the effectiveness of various management options within the watershed to restore water quality in the bay both now and under future climate.
