The Severn Sound Environmental Association’s Open Water Monitoring Program monitors the environmental quality of Severn Sound open water for indicators of eutrophication. The Severn Sound RAP Stage 3 Report called for continued monitoring of open waters of Severn Sound in order to assess changes in trophic status in relation to remedial actions and other ecosystem changes in the area (e.g. invasive species).
Fourteen open water stations are sampled during biweekly sampling runs during the ice-free season. Samples conducted at each station include: euphotic zone composite samples of nutrients (total phosphorus, ammonia, nitrate, total Kjeldahl nitrogen), chlorophyll a and phytoplankton; water clarity is measured using a Secchi disc; and vertical profiles of temperature, dissolved oxygen, and conductivity.
