ANALYSIS OF THE MACROZOOBENTHOS DISTRIBUT ION ON THE NOVAYA-ZEMLYA SHELF BARENTS SEA BY METHOD OF SELF-ORGANIZING MODELING BASED ON THE RESULTS OF THE UNDERWATER PHOTOGRAPHY

On the base of the underwater photographies and Group Method of Data H andling Algorythm the distribution of common species and trophic group s of zoobenthos on Novaya Zemlya shelf of the Barents Sea has been inv estigated. The remoteness of sampling localities from the coast, depth , lithological composition of sediments, geomorphological characterist ics of samples, sedimentation regime, maintenance of desintegrated roc k material on bottom, concentration of organic carbon in sediments are tested as explanatory variables. The optimum models ensuring the mean accuracy of prognosis within 15% of the real ones are obtained on the 1 - 5 rows of selection. Advantages, limitations and perspectives of self-organizing modelling and use of underwater photography in hydrobi ological practice are discussed.
