  abstract = {{T}he extent of light absorption in the near-infrared spectral region ({NIR}; 700–900 nm) of natural suspended particles was investigated by determining the absorption and mass-specific absorption coefficients of samples from different environments: river, coastal waters, tropical lagoon, and oceanic waters. {L}arge amounts of sample were collected onto glass-fiber filters and measured inside the integrating sphere of a spectrophotometer. {T}he absorption coefficient of particle suspension was also determined for visible wavelengths with a point-source integrating cavity absorption meter. {M}easurable nonzero particulate absorption in the {NIR} was determined in all samples, even in algal cultures. {I}t was highest in the river samples (e.g., 1.7 m21 at 850 nm), reaching values similar to the {NIR} absorption of pure water—a strong {NIR} absorber. {L}owest values were in oligotrophic waters and in algal cultures. {R}atios of absorption at 750 nm to absorption at 442 and 672 nm varied between 2% to 30% and 3% to 80%, respectively. {M}ass-specific absorption in the {NIR} at 850 nm was also highest in the river (0.012 m2 g21) and lowest in oligotrophic waters (0.002–0.003 m2 g21). {T}he observed {NIR} absorption can partly be explained by absorption of minerogenic particles, whereas the contribution of organic detritus to the {NIR} absorption is still mostly unknown.},
