Аннотация: In deep stratified lakes, the processes of growth and mortality of zooplankton populations result in uneven vertical distributions of living and dead organisms in a water column. The carcasses in the water are removed by sinking, degradation due to microbial decomposition and detritivory, etc. In the case of the epilimnion maximum Показать полностьюof zooplankton, provided that the degradation prevails over the sinking, the downward flux of carcasses exponentially decays with depth. This vertical profile of dead organisms, demonstrating the decline in meta- and hypoliminon, can be described by the numerical model presented in this paper. The model approximation of the field data makes it possible to determine non-predator mortality rate m and degradation rate D in relative terms (m/v and D/v, vsinking velocity) or absolute values (with defined v). For the case of the copepod population of Arctodiaptomus salinus in Lake Shira, the calculated m and D (medians of 0.13 and 0.26 day(-1), respectively) were in a good agreement with the literature data. This method also gives the advantage of using the depth-dependent sinking velocity v. This study reviews the problem of creating an algorithm for classifying objects in a Grid system, which will allow the automation of this process to proceed. Splitting objects into classes allows you to effectively manage the resources and processes that
