dc.description.abstract | Harmful algal blooms (HABs) have continuously occurred around the coastal waters of Korean peninsula since the late 1980s. Satellite remote sensing has been used to detect and monitor the temporal and spatial distributions of widespread HABs. To use satellite remote sensing more effectively in detecting HABs, we should understand optical characteristics such as absorption and remote sensing reflectance of HAB causative species. In this study, we analyzed the characteristics of absorption coefficients and simulated remote sensing reflectance (Rrs) of the four dinoflagellate HAB species (Cochlodinium polykrikoides, Akashiwo sanguinea, Alexandrium tamarense and Scrippsiella trochoidea) which are among the major HAB species in Korean waters. We calculated the absorption coefficients (aph) of four HAB species using culture samples. The absorption spectrums of the four dinoflagellate HAB species show similar patterns at major and minor peaks near 440, 680 nm and 460nm, respectively. However, the shapes and magnitudes of these spectrums show clear differences. Next, we used the HydroLight (version 5.2 Mobley, 1995) to simulate the remote sensing reflectance under dynamic optical conditions. For HydroLight simulations, we used the absorption coefficients measured from the samples and absorption and backscattering coefficients of other optical constituents from International Ocean-Color Coordinating Group database (IOCCG Reps.
