Abstract

The potential of using remote sensing for the detection of chlorophyll-a (CHL), dissolved organic matter (DOM), and suspended matter (SM) concentrations in coastal and inland waters was investigated using measurements of (ir)radiance spectral with simultaneous earth-reference data. The range of CHL was 0.1 to 350 μg/l, SM was 0.1 to 43 mg/l, and DOM absorption at the 380-nm wavelength was 0.1 to 10-1. Factor and signature analysis reveal allometric relationships between constituent concentrations Ck and functions of reflectance Zk of the type Ck = Zkb. Appropriate functions of R were found: zchl = R(700)/R(675), Zsm = R(560)/R(520), and Zdom = {R(480) + k[R(700)/R(675)]}/R(630). The maximum estimation errors were: CHL, 3 μg/l; DOM, 0.065 μgC/l; and SM, 4 mg/l.
