Elucidating controls on cyanobacteria bloom timing and intensity via Bayesian mechanistic modeling

SCIENCE OF THE TOTAL ENVIRONMENT, 755.

author keywords: Eutrophication; Harmful algal blooms; Bayesian inference; Process-based modeling; Great Lakes; Hindcasts and projections
MeSH headings : Bayes Theorem; Chlorophyll A; Cyanobacteria; Eutrophication; Harmful Algal Bloom; Lakes; Phosphorus
TL;DR: A mechanistic model describing June-October dynamics of chlorophyll a, nitrogen, and phosphorus near the Maumee River outlet, where blooms typically initiate and are most severe, highlights the role of temperature in regulating bloom initiation and subsequent loss rates and suggests that a 2 °C increase could lead to blooms that start about 10 days earlier and grow 23% more intense.
