MARYLAND GENERAL TRENDS 1985-2002 Choptank River: Chlorophyll Increasing Phytoplankton biomass Mixed (ET5.1 decreasing; ET5.2 increasing) Phytoplankton abundance Increasing (ET5.2) Diatom Biomass Mixed (ET5.1 decreasing; ET5.2 increasing) inoflagellate Biomass Increasing (ET5.2) Potomac River: Chlorophyll Increasing Productivity Increasing (TF2.3 and LE2.2) Phytoplankton biomass Increasing (TF2.3) Phytoplankton abundance Increasing Cyanobacteria biomass Increasing (TF2.3 and LE2.2) Diatom biomass Increasing (LE2.2) Patuxent River: Phytoplankton abundance Increasing (LE1.1) Diatom biomass Increasing (LE1.1) MD Mainstem Bay: Phytoplankton abundance Increasing Cyanobacteria biomass Increasing
