Hyperspectral Analysis of Submerged Aquatic Vegetation

The Science Issue and Relevance
Methodology for Addressing the Issue
Working in cooperation with the NPS and the Western Pennsylvania Conservancy, USGS scientists are utilizing hyperspectral data from the Civil Air Patrol (CAP) ARCHER (Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance) systems to map submerged aquatic vegetation (SAV), along with the invasive algae Didymosphenia geminata (didymo, a.k.a. "rock snot"), in the Delaware Water Gap National Recreation Area and Upper Delaware Scenic and Recreational River.
Field work and additional data collection, especially in situ spectral data of submerged aquatic vegetation (SAV), will help refine the spectral "signatures" of SAV and will assist National Park Service managers in the protection of sensitive aquatic resources.
Key Words: Hyperspectral imaging, chemometric analysis, invasive species, submerged aquatic vegetation
