Abstract:
We propose to take concurrent field measurements in the coral reef environments of the Hawaii region to support the 2016 HyspIRI Airborne Campaigns. In addition to obtain hyperspectral (350-800 nm, 137 bands) remote-sensing reflectance (Rrs, sr-1) with our unique skylight-blocked approach and system, we will collect collocated bathymetry, water's inherent optical properties and videos of the submerged substrates. These measured Rrs will be compared with the match-up AVIRIS Rrs generated at the JPL AVIRIS computing facility to evaluate the quality of AVIRIS surface reflectance data product over coral reef environments. Further, these data will be used to refine remote sensing algorithms for the identification of live corals and to assess the spatial coverage of live corals for the entire flight line. With the collocated optical properties, we will also analyze the relationship between live coral coverage and light availability. These data and efforts will greatly improve our understanding and capabilities of using HyspIRI-like data to observe and monitor coral reef environments.
