Chesapeake Bay Program Water Quality Database

Parameters sampled include: temperature (WTEMP), dissolved oxygen (DO), conductivity (COND), salinity (SALINITY), ph (pH), secchi depth (SECCHI), chlorophyll a (CHLA), pheophytin (PHEO), silica, whole and filtered (SIW, SIF), total suspended solids (TSS), total phosphorus (TP), total dissolved phosphorus (TDP), particulate phosphorus (PP), orthophosphate whole and filtered (PO4W, PO4F), total dissolved nitrogen (TDN), total Kjeldahl nitrogen whole and filtered (TKNW, TKNF), nitrite plus nitrate whole and filtered (NO23W, NO23F), nitrite whole and filtered (NO2W, NO2F), nitrate whole and filtered (NO3W, NO3F), ammonium whole and filtered (NH4W, NH4F), particulate organic nitrogen (PN), total organic carbon (TOC), dissolved organic carbon (DOC), particulate organic carbon (POC).

Some parameters have been dropped or replaced over time, and several additional parameters are available for the tributary stations. See the station listing at www.chesapeakebay.net/data/index.htm This database was created to store grant deliverable data and associated tributary data collected as part of the Chesapeake Bay Program water quality monitoring program. These data are used to guide environmental decisions and to monitor responses of the system to management actions.
