Formatted Abstract/Summary
Currently, spatial light attenuation and water clarity can be estimated from diffuse attenuation coefficient at wavelength 490 nm (Kd490) available from satellite data. In the present study, we investigated the performance of existing satellite Kd490 algorithms in near-shore seagrass environment using available in situ data. We also examined the use of moderate-spatial resolution, multispectral imagery data of Landsat and ALOS AVNIR-2 to estimate both measured and calculated Kd490. Finally, we demonstrated conceptually on how Kd490 can be related to Kd of photosynthetically available radiation (KdPAR). The results showed that existing Kd490 algorithms can be used to estimate in situ Kd490 for sites with Kd490 < 1 m−1. Systematic and strong relationships were observed between blue-green ratio of Landsat and AVNIR 2 bands, and either in situ Kd490 or calculated Kd490 from MERIS/MODIS algorithms. For some selected sites KdPAR can be well reconstructed from Kd490 using empirical model from which correlation between Kd490 and KdPAR can then be developed.
