  1. The Use of Innovative Technologies to Monitor and Manage Chesapeake Bay Water and Habitat Quality Christopher Heyer, Mark Trice, Bruce Michael,Ken Moore, Willy Reay, Dave Wilcox Estuarine Research Federation – Chesapeake Research Colloquium Norfolk, VA 21 October 2005

  2. Operational • Special Projects Monitoring Components • Fixed Station Monitoring • Real-Time Monitoring Network • Water Quality Mapping • DataView • Sensor Testing • Vertical Profilers • Remote Sensing • CBOS • Event Triggered Sampling • Current Measurements • AUV

  3. Continuous Monitoring • 39 stations statewide • Generally, deployed April - October • Hourly telemetry from 18 stations to website • Most meters set at 1-meter below surface • Measures water quality parameters every 15 minutes • Provides temporally intensive data during extreme events and other times it’s impractical to deploy field crews Dissolved Oxygen, Turbidity, Chlorophyll, Water Temperature,Salinity, pH

  4. System Status and Alerts Telemetry Status Dissolved Oxygen & Chlorophyll Exceedances Equipment Malfunction

  5. 25ug/l Chl a Threshold Magothy River 06/27/01 90% Confidence Pass Fail Uncertain Water Quality Mapping • Data collected every 4 seconds • Speeds up to 25 knots • 3,500 - 15,000 data readings/day • Spatially explicit data are useful for delineating habitat conditions

  6. Water Quality Mapping New Design

  8. DATAFLOW Visualization Software New Real-Time Mapping (DATAVIEW)

  9. 95% Confidence A Threshold is Violated Uncertain 95% Confidence A Threshold is not Violated Benefits of DATAVIEW • Use existing GIS data (bathymetry, SAV coverage, past cruise tracks, past data, etc.) • Alert system for collecting samples or equipment malfunction • Delineate blooms, turbidity max zones, anoxia • Probability mapping which allows resampling to improve measurement certainty. • Ground-Truthing • SAV distribution • Remote sensing imagery

  10. Sensor Testing • OpticalDissolved OxygenSensors • CyanobacteriaFluorescenceSensors

  11. Vertical Profilers Electronics Package Battery Computer Controlled Winch
