CHARACTERISTICS OF SUSPENSION IN THE KERCH SOUND ACCORDING TO CONTACT AND SENSING MEASUREMENTS

Kushnir V.M., Berdnikov S.V.

Suspension characteristics in the Kerch strait were studied on the basis of remote sensing measurements of the optical characteristics by MODIS scanners in the red and IR spectrum as well as on the basis of the contact measurements of the suspension concentration in separate points. Functional dependence of this parameter on the colour index for waves of 0,645 and 0,8585 microns is received. This dependence is used for definition of concentration of the small (0,01 ≤ r ≤ 1 microns) and large (1 ≤ r ≤ 10 microns) particles of the suspension, parametres of the probability distributions and number of these particles in volume unit. Comparison of the received optical parametres with the characteristic data for the Azov – Black Sea basin has shown satisfactory conformity of these values.
