1 WATERS (WATer and Environmental Research Systems) Network Pan-American Sensors for Environmental Observatories (PASEO) Workshop Bahia Blanca June A Coastal Margin Observation/Assessment System WATERs Testbed Corpus Christi Bay, TX

2 TestBed Discussion Highlights NSF CLEANER WATERS program goals Eastern Coastal Margin Research Plans & Activities Corpus Christi Bay as a Testbed Example Develop an observation/assessment system to characterize water quality at higher spatial and temporal resolution in the Coastal Margin.

3 Eastern Coastal Margin CLEANER/WATERS Environmental Analysis Network Eastern Coastal Conceptual Design Coastal Watershed and Rivers to Shelf Boundary GoM EFF Pacific EFF Great Lakes EFF Atlantic EFF This study area includes all the Great Lakes, estuaries and coastal waters. Sensor network design considered how to instrument extensive areas of open water. The extent of this region begins with the coastal plain and extended out to the 3 coastal waters (200 km X 200 km)

4 Eastern Coastal Design Projected population change and human activity from Variable Coastal Plain Possible sites and configurations

5 Develop a Collaborative Engineering/Environmental Analysis Network, using high performance tools and infrastructure, to transform our scientific understanding of environmental change in Human Dominated Ecosystems (HuDEs)
