Abstract

Mathematical modelling of the ecosystem of the Northโ€West shelf of the Black Sea is based on the method of aggregation and averaging with the subsequent hierarchic decomposition (BELYAEV, 1987; BELYAEV and KONDUFOROVA, 1989). This approach includes the stepโ€byโ€step comparison of the modelling results with field observations. The observations have been performed during the integrated oceanographic expedition of the research vessel โ€œProfessor Kolesnikovโ€ (1987), for the first time specially organized to verify the modelling results. The comparison of the results of modelling and observation demonstrated that their agreement is satisfactory quantitatively and qualitatively. The efficiency of using models of optical fields for verification is also shown.

The parameters of the best-fitting ellipsoid have been derived using the latest spherical harmonics of the Phobos topography (Duxbury, 1989) by solution of non-linear overdetermined inverse problem. The lengths of the equatorial axes of the ellipsoid have been determined (a = 12.9 km, b = 11.4 km).
