Description:
Annual monitoring of indicators of the ecological condition of bays and estuaries within the Virginian Province (Cape Cod, MA to Cape Henry, VA) was conducted by the U.S. EPA's Environmental Monitoring and Assessment Program (EMAP) during July, August, and September, 1991. ata were collected at 154 stations within the Province. ndicators monitored included water quality (temperature, salinity, water clarity, and dissolved oxygen concentration), sediment contamination, sediment toxicity, benthic community structure, fish community structure, fish gross external pathology, and fish tissue contamination. ata are used to estimate the current status of the ecological condition of Virginian Province estuarine resources, and provide a baseline for identifying future trends. umulative distribution functions (CDFS) and bar charts are utilized to graphically display data. stimates, with 95% confidence intervals, are provided of the areal extent of degraded resources within the Province for those indicators where "degradation" can be defined. ata are also presented by estuarine class: arge estuaries, small estuarine systems, and large tidal rivers. ncluded, as an appendix, are sub-population estimates for Chesapeake Bay and Long Island Sound.
