3. Scientific Basis: Vegetation Ecosystem Properties with Spectroscopy Species Type 90% accurate Species Fractional Cover (Quercus agrifolia) Full spectrum measurement (380- 2500 nm) allows derivation of vegetation species and functional type and physiological condition Dennison and Roberts, 2003, Remote Sens. Environ.

5. Most vulnerable coastline (including calibration sites) surveyed with acceptable to zero cloud cover, including oil slick imaging. thanks to the dedicated NASA-led interagency team and no small amount of weather (clouds) luck

9. Key Scientific Coastal Ecosystem Questions Which coastal vegetation types/communities are most heavily impacted by oil? Can oil in the canopy understory be detected directly (i.e., due to its spectroscopic signature) or only indirectly by vegetation stress indicators? Given different mitigation strategies, what are the most effective in reducing adverse oil impacts? Can knowledge of past distribution of plant types/communities aid recovery and remediation efforts and/or aid in targeting priority sites for recovery efforts?

12. Species Dominants: NW R13 1650, 830, 677 RGB Wetland Dominants Developed a spectral library using USGS CRMS sites Selected optimal endmembers and mapped with MESMA the wetland dominants Four species mapped included two spartina, aphragmites, and a distichlis AVIRIS ecosystem species mapping

13. Species Dominants: SE R13 1650, 830, 677 RGB Wetland Dominants Spartina more dominant towards Northwest Phragmites dominates towards southeast Distichlis is abundant in zones with high reflectance due to low stature
