SHIP BOARD MEASUREMENTS OF IN-WATER PROPERTIES AND REMOTE SENSING REFLECTANCE FOR AIRCRAFT SENSOR VALIDATION IN EAST SOUND, ORCAS ISLAND, WASHINGTON
 
A field experiment was undertaken in East Sound, Orcas Island, Washington, with the primary objective of sea-truthing a new aircraft-mounted high sensitivity optical sensor, the Ocean PHILLS (Portable Hyperspectral Imaging Low-Light Spectrometer). A series of stations crossing a shallow sill near the southern end of East Sound were occupied by the University of Washington research vessel Clifford A. Barnes daily from July 28th through August 11th, 1998. While the aircraft sensor collected data along a series of flight lines crossing East Sound, simultaneous measurements of remote sensing reflectance and water-leaving radiance were taken from the R/V Barnes using a hand-held spectrometer. Additionally, an in-water package, on loan from the Oregon State University, measured surface to near-bottom profiles of dissolved (yellow matter) absorption, particulate absorption, total absorption, beam attenuation, back scattering, chlorophyll fluorescence, upwelling radiance, downwelling irradiance, temperature and conductivity. Also, near surface upwelling radiance and downwelling irradiance were measured and water bottle samples were taken at discrete depths and measured for chlorophyll. As a chief goal of this experiment, we relate the above water remote sensing reflectance measurements to vertical profile data, which we then use to relate the vertical profile data to the aircraft imagery.
