• An empirical optical model for estimating the concentration of suspended particulate matter (C SPM ) was developed in the upper part of the Saint Lawrence Estuary based on remote sensing reflectance (R rs ) measurements corresponding to medium-resolution imaging spectrometer (MERIS) spectral channels 7 and 9 (i.e., wavelengths centered at 665 and 708 nm, respectively). Sensitivity of C SPM estimates to changes in mineral content of suspended particulates was investigated based on simulated R rs values. For June 2012 measurements, C SPM varied with values following a power-type relationship (y = 235.7 x 8.321 , r 2 = 0.7, N = 10). In addition, numerical experiments and analysis of regression type II showed that exponent parameter of this biogeo-optical model decreased as suspended particulates become more enriched in organic matter.
