提出了一种测定颗粒矿物质（CPMM）和颗粒有机物（CPOM）浓度的方法。CPMM和CPOM的值使用经验公式从光吸收的光谱系数aPOM（440）和aPMM（750）的测量计算。后者是通过比较用重量法测得的悬浮固体的浓度与沉淀在膜过滤器上的悬浮物的光密度的光谱值而获得的。使用的数据是内陆和边缘海以及开阔洋的沿海沃茨的典型数据，涵盖了氯化石蜡和氯化石蜡的浓度分别为三个和两个数量级的范围。
A method to determine the concentrations of the particulate mineral matter (CPMM) and the particulate organic matter (CPOM) is suggested. The values of CPMM and CPOM are calculated from the measurements of the spectral coefficients of the light absorption aPOM(440) and aPMM(750) using empirical equations. The latter have been obtained by comparing the concentrations of the suspended solids measured by means of the gravimetric method with the spectral values of the optical density of the suspended matter settled on membrane filters. The data used are typical of the coastal waters of inland and marginal seas and the open ocean and cover the range of three and two orders of magnitude for the concentrations of CPMM and CPOM, respectively.
