  1. Maryland DNR’sWater Quality Programsand Use of Remote Sensing Mark Trice Program Chief, Water Quality Informatics mtrice@dnr.state.md.us www.eyesonthebay.net Twitter: @eyesonthebay

  2. DNR’s Tidal Water Quality Mission 1. Assess Water Quality Criteria 2. Determine WQ Status & Trends for Tidal Waters 3. Target Habitat Restoration Potential 4. Provide Data Access to Public 5. Determine Impacts of Weather & HABs

  3. Long-Term Fixed Station Monitoring • Continuous In Situ Monitoring Shallow Water Monitoring Component • Water Quality Mapping Water Quality Monitoring Programs • Remote Sensing

  4. Parameters of Interest • Nutrients • Sediments • Dissolved Oxygen • Light/Clarity/PAR • Chlorophyll from a variety of species • Algal species and toxins • Temperature and Salinity • pH

  5. Eyes on the Baywww.eyesonthebay.net 46% of website page visits are to Satellite Imagery

  6. Water Quality Remote Sensing

  7. Qualitative Usages-The Power of ImageryTropical Storm Lee earthobservatory.nasa.gov/IOTD/view.php?id=52169

  8. MODIS Water Temperature http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17082 • Uses • Fishing Seasons • Vibrio • Population Shifts • Public Interest

  9. Water Quality Mapping 8/14/2005 8/15/2005 8/17/2005 8/18/2005 Area of DATAFLOW Collection Water Quality Mapping 8/18/2005 Use of MODIS Satellite Data to Guide Field Sampling A 1-mile long fish kill as reported by MDE occurred on August 16/17, 2005 near Marker 66 in the Chesapeake Bay off of Smith Island. Brownish-red water was observed in a television video of the fish kill. MODIS Satellite Chlorophyll Main Bay Near Marker 66 off of Smith Island shows bloom conditions on August 15 and 17 (Above). Water Quality Mapping Data collected on August 18, 2005 with the DATAFLOW/DATAVIEW system shows low chlorophyll values (<6 ug/l) when the bloom dissipated (right), which corresponds to low observed satellite chlorophyll data on that same day (above right).

  10. Decision Support Systems • Improve ecological forecasts/report cards • Provide additional assessment for water quality indicators. • Improve in situ interpolation methods • Harmful Algal Bloom Alert System • Translate remote sensing data into usable GIS format for managers • Regional algorithms to improve estuarine water quality estimation.

  11. Resolution Coverage Comparability Challenges Estuarine Complexity Integration Cost/ Support Mark Trice Program Chief, Water Quality Informatics mtrice@dnr.state.md.us www.eyesonthebay.net Twitter: @eyesonthebay
