Simultaneous Estimation of SS and Chlorophyll in Shallow Water through Remote Sensing

Abstract

The simultaneous estimation of SS and Chlorophyll-a (Chl.a) in shallow water through remote sensing was tried in this study. Lake Teganuma located in Chiba Prefecture was selected as a test site. Twelve spectral reflectance / Chl.a data sets were acquired using outboard boat in the lake on 28 May 2009 and 22 Oct. 2008. These data sets were related to SS or Chl.a using a simple single band or two band ratio models. As a result, a statically significant correlation was observed between "a reflectance of the simulated ALOS/AVNIR-2 Band 4 (760-890nm)" and "SS", or "reflectance ratio of the simulated AVNIR-2 band 3 (610-690nm) and band 4" and "Chl.a". These models were validated though the ALOS/AVNIR-2 data and the buoy data set on 20 May 2008 and 28 Oct. 2009.
