Test understanding of mechanisms driving coastal eutrophication and formation of seasonal hypoxia, including nutrient sources and biogeochemical pathways, physical drivers (stratification, circulation), ecological consequences (community shifts, benthic mortality, altered food webs), monitoring indicators and modeling approaches, and mitigation/management strategies. Assess ability to interpret relevant datasets (nutrient loads, DO time series, chlorophyll, benthic surveys), diagnose dominant causes regionally, and evaluate trade-offs of remediation options.
