Presentation Transcript

  1. Earth Scan Lab, Coastal Studies Institute Louisiana State Unviersity Baton Rouge, Louisiana Directors: Oscar Huh, Nan Walker Associate Director: Larry Rouse System Manager: Alaric Haag Missions: Emergency Response Education ResearchReal-time data: NOAA AVHRR GOES-8 GVAR Orbview-2 SeaWiFS Terra/Aqua MODIS OCEANSAT-1 OCMRADARSAT/ERS-2 SAR

  2. Coastal Applications for Remote Sensing *Storm/hurricane tracking and impacts *Surveillance of high velocity shelf and slope currents *Tracking/prediction of oil spills * Map Coastal Flooding * Managing Eutrophication/Hypoxia * Harmful algal blooms (HABs) * Managing river diversions - sediments, algal blooms, and salinity * Assess Land Loss or Gain *Surveillance of marsh/wetland changes

  3. IR channels: 3.8-4.0 10.2-11.2 11.5-12.5 microns

  4. Night-time composites were produced using warmest pixels over 10 hours

  5. Quantifying in-water substances with SeaWiFS Chlorophyll a Suspended Sediment

  6. Critical Resolution Needs * Spectral: narrow bands * Spatial: 250m-1 km * Temporal: 15-30 minutes * Radiometric: 12 bit

  7. Remote Sensing Needs in Coastal Zone ParameterWavelength Suspended sediments: 0.64 µm Chlorophyll a, harmful algal blooms: 0.49 µm, 0.55 µm Land/water boundary, flooding: 0.86 µm Sea surface temperature: 3.9, 11, 12 µm Spatial resolution < 0.5 km visible, 1 km thermal Temporal resolution 15-30 minutes
