Specific Absorption And Backscatter Coefficient Signatures In Southeastern Atlantic Coastal Waters, Charles R. Bostater
Specific Absorption And Backscatter Coefficient Signatures In Southeastern Atlantic Coastal Waters, Charles R. Bostater
Ocean Engineering and Marine Sciences Faculty Publications
Measurements of natural water samples in the field and laboratory of hyperspectral signatures of total absorption and reflectance were obtained using long pathlength absorption systems (50 cm pathlength). Water was sampled in Indian River Lagoon, Banana River and Port Canaveral, Fl. Stations were also occupied in near coastal waters out to the edge ofthe Gulf Stream in the vicinity of Kennedy Space Center, Fl. and estuarine waters along Port Royal Sound and along the Beaufort River tidal area in South Carolina. The measurements were utilized to calculate natural water specific absorption, total backscatter and specific backscatter optical signatures. The resulting …

Imaging Derivative Spectroscopy For Vegetation Dysfunction Assessments, Charles R. Bostater
Ocean Engineering and Marine Sciences Faculty Publications
The practical application of current airborne and future satellite or space station based high spectral resolution (hyperspectral) imagery to vegetative canopies (sparse or dense) and resulting derived bio-physical variables will depend upon our ability to rapidly apply scientifically based algorithms. Key to these rapid assessments is the selection ofthe best or optimal channels or bands for detection of plant stress or dysfunction. Previous work '2,3,4,5 has demonstrated the potential of utilizing high spectral resolution optical signatures for detecting plant stress related to the vegetation's moisture within the leaf structure. Future algorithms and techniques need to discriminate plant species as well …
