The modernization of limnological equipment used for the sampling of bottom sediments is systematically considered. Conceptual and set-theoretical models of the functioning and application of bottom grab sampling are proposed. A classification of existing samplers is given, their distinctive characteristics are considered, and a historical overview of upgrades is carried out. The task of designing acceptable system engineering solutions for bottom grab sampling is reduced to finding options that meet functional and ergonomic criteria. The structure and functions of bottom grab sampling software and hardware are considered taking into account the cost of the entire life cycle of the equipment. The importance of taking into account the ergonomics and safety of the use of the measuring instruments and sampling equipment during their design and modernization is emphasized. The version of the bottom grab sampler is distinguished by the use of sampling quality analysis when automating the operation of buckets. Bottom grab sampling was successfully tested during an expedition on Lake Ladoga. The collected material and the changes in acceleration at the time of the landing of the bottom grab sampler on the bottom sediment is used to configure the structure and train the artificial neural network, on the basis of which the on-board system for recognizing types of bottom surfaces.
Keywords: system analysis, equipment life cycle, sampling, bottom grab, ergonomics, bottom soil, artificial neural networks.
