Purposes: • Provide ground truth sediment and salinity data
from the Mobile Bay plume for testing of algorithms for remote sensing
• Create leveraging cross-connections between NASA projects & products and Northern Gulf Institute modeling and management initiatives
Participants:• McAnally & Martin, MSU Civil & Environmental Engineering• Du & Topsakal, MSU Electrical & Computer Engineering• Ellis, NASA Stennis Space Center• Dardeau & Linn, Dauphin Island Sea Lab
Approach:
• Multi-agency workshop designed field program – Nov 2007
• Data Collection Cruises – Nov 2007 forward
• Applications of data by participants
• Documentation and reporting
• Samples: One-liter water samples at surface, 1m, & 2m at ~30 locations analyzed for: DOC, PC, TSS, Chloro-a
• Vertical Profiles: light extinction, temp, DO, conductivity, & turbidity
• Cruises Monthly since 11/07
