Abstract
Data of optical characteristics of lake Issyk-Kul measured with the complex for passive remote sensing Ecological Monitoring of Marine Areas (EMMA) from board a vessel as well as measurement data obtained for water samples allowed us to develop and validate a new technique for oligotrophic water content estimation. This technique is the third part of the method for remote estimation of the main natural constituents concentration in sea or lake waters using light absorption spectrum of pure sea water. The method was suggested by us earlier for mesotrophic and eutrophic waters. Using this technique the estimates of concentration of phytoplankton, colored organic matter, and suspended matter and their distribution over the lake during the three-day experiment in July, 2018, were obtained.
