Patterns and Trends in Secchi Disk Depth Over Three Decades in the Chesapeake Bay Estuarine Complex
Publication date:This study conducted a comprehensive statistical analysis of spatial and temporal variations in Secchi disk depth and the key internal and external variables that influence its variability in the Chesapeake Bay and its tidal tributaries.
A Generalized Additive Model Approach to Evaluating Water Quality
Publication date:This study used Generalized Additive Models (GAMs) to evaluate a diverse suite of water quality constituents over a 32-year period in the Chesapeake Bay, providing a tool for developing insights to a range of management- and research-focused questions.
