Benchmarks for Nitrogen, Phosphorus, Chlorophyll and Suspended Sediments in Chesapeake Bay

Published: April 10, 2002

One of the Tidal monitoring and Analysis Workgroup's primary responsibilities is assessing and reporting the status and trends of nutrients and other parameters monitored within the scope of the Chesapeake Bay Program water quality and biological monitoring programs. Status answers the question are we relative to benchmarks indicating where we should; want or expect to be? Trend, in conjunction with status, answers the questions: Are we improving or getting worse relative to those benchmarks? The objective of this project is to develop benchmarks for Total Phosphorus (TP), Total Nitrogen (TN), Chlorophyll (CHLa) and suspended solids (TSS).
