Ship-based measurements of the biooptical characteristics of Lake Issyk-Kul waters with the passive remote sensing complex Ecological Monitoring of Marine Areas (EMMA), as well as measurements in water samples, were used to develop and test a new technique for estimating the composition of oligotrophic waters. It is the third part of the method for remote estimation of the concentrations of the main natural constituents in sea or lake waters using the spectrum of light absorption by pure sea water which we developed earlier for mesotrophic and eutrophic waters. This technique was used to estimate the concentrations of pigments of phytoplankton, colored organic matter, and suspension and their distribution over the lake water basin during three-day experiment in July 2018.
