Abstract :
Moreton Bay is the Australian EO1-Hyperion coastal site used for Cal/Val activities. Moreton Bay shows spatial gradients in optical depth, bathymetry, and substrate composition. The turbid and humic river inputs, as well as the open ocean flushing, determine the water quality of the bay. Lyngbya toxic algae blooms have become a serious environmental and health concern. The field campaigns, carried out to coincide with Hyperion overpasses, focussed on the retrieval of inherent optical properties, apparent optical properties, substrate reflectance spectra and water quality parameters. Spectra from a 12 January 2001 Hyperion image show very close agreement to in situ upwelling radiance spectra
