Abstract	:	My research focuses on the development and application of hyperspectral remote sensing as avaluable component in the assessment and management of coral ecosystems. Remote sensing provides animportant quantitative ability to investigate the spatial dynamics of coral health and evaluate the impacts oflocal, regional and global change on this important natural resource. Furthermore, advances in detectorcapabilities and analysis methods, particularly with respect to hyperspectral remote sensing, are alsoincreasing the accuracy and level of effectiveness of the resulting data products. Using imagery of KaneoheBay and French Frigate Shoals in the Hawaiian Islands, acquired in 2000 by NASA's Airborne VisibleInfraRed Imaging Spectrometer (AVIRIS), I developed, applied and evaluated algorithms for analyzingcoral reefs using hyperspectral remote sensing data. Research included developing methods for acquiring insitu underwater reflectance, collecting spectral measurements of the dominant bottom components inKaneohe Bay, applying atmospheric correction and sunglint removal algorithms, employing a semi-analytical optimization model to derive bathymetry and aquatic optical properties, and developing a linearunrnixing approach for deriving bottom composition. Additionally, algorithm development focused onusing fundamental scientific principals to facilitate the portability of methods to diverse geographiclocations and across variable environmental conditions.
