Determination of Phytoplankton Carbon by the Content of Suspended Organic Matter and Chlorophyll a in Water

Observations on different types of water bodies were carried out to study the relationship between chlorophyll and suspended organic carbon. Using the literature and proprietary material, a simple method for estimating phytoplankton carbon in situ depending on the concentration of chlorophyll a, based on classical and quantile regression analysis, is demonstrated. Calculations yielded the ordinary estimates of the carbon/chlorophyll ratios ranging from 25 to 150.
