1. Enhancing Water Quality in MARACOOS Kevin Sellner Executive Director Chesapeake Research Consortium 15 December 2011 Sorry I could not attend!

2. CBOS & WQ Most active and continuous WQ monitoring via MD DNR and VA DEQ WQ Monitoring Program – Since 1984, open and shallow water ship collections – Shallow water continuous data collection with moored/fixed sensor packages Other WQ monitoring includes moored instrumentation from UMCES and NOAA Chesapeake Bay Office Event Response ship & satellite sampling: NCBO, NOAA Oxford Lab, MD DNR, VA DEQ, ODU, UMCES, NASA, Hampton Roads Sanitation District, NOAA NOS

3. Why Enhanced? Bay-wide TMDL models driven by these measurements All jurisdictions in Bay watershed must meet implementation goals connected to load reduction targets by 2025 Plans for 2012-2017 – New shallow water (<3 m) living resource ribbon hydrodynamic/WQ model for SAV/clarity, oysters, wetlands, erosion/resuspension to link with existing CH3D/ICM open water model – All driven/informed by continuous in situ measurements from sensor packages, not used previously – Expand all models to include climate change, climate-driven DO dynamics, waves, menhaden Again, ALL informed/driven by the monitoring by CBOS partners so implementation of OOS packages insures future basin WQ predictions
