Abstract:An atlas of oceanographic data on the shelf zone of Sakhalin Island and a mathematical model describing the transformations of nutrient compounds (N, P, Si, C) are used to study the biotransformation and transport of organic and mineral components of these elements in the La Perouse Strait. To make the analysis more convenient, the area under examination was divided into four zones, which differ in the conditions of transport of matter in water flows. Transport calculations are made using a complex graphic method with geostrophic approximation, which takes into account the results of instrumental observations of flow velocities, sea level variations, and annual variations in the water volumes. The obtained patterns of dynamics of nutrient compounds are compared with the results of modeling of internal and external fluxes of those components. Calculated fluxes of the elements were used to assess the rate of chemicals and biomass transport through the boundaries of water areas (in particular, between the Seas of Japan and Okhotsk).
