Modeling of the Annual and Spectral Evolution of Hydrooptical Characteristics Using a Model for Shelf Ecosystem and Remote Observations

摘要

Mathematical modeling of the ecosystem in the northwestern shelf of the Caspian Sea is based on the method of aggregation and averaging with the subsequent hierarchic decomposition. This approach includes a step-by-step comparison of the modeling results with the data of observations. A block of optical characteristics (absorption coefficient, backscattering coefficient, and coefficient of diffuse light reflection) built into the model made it possible to use the data of simultaneous contact and remote observations. The observations were performed during the expedition of R/V Tantal (2004-2005) together with the data of the SeaWiFS satellite ocean color scanner. A comparison of the results of the modeling and the data of observations demonstrated their qualitative and quantitative agreement, especially in the case of the coefficient of diffuse light reflection.
