Abstract:
Coral reefs are the marine ecosystems that important in world's ocean. Coral reefs are
under risk rate due to increasing of environmental and anthropogenic stress.
Determining a subset of wavelength that best discriminate benthic communities is
important for the development of remote sensing. The spectral reflectance data has the
potential to be applied in remote sensing imagery and for mapping properties. The
spectral reflectance of coral reef benthic communities was recorded using the
underwater hyperspectral instrument of Satlantic HyperOCR. In- situ upwelling and
downwelling data were collected for four substrates of Bidong Island benthic
communities
