Indirect Estimation of Water Productivity by the Chlorophyll Content

Abstract

Literature and author's data from various areas of the World Ocean and seas of the Russian Federation are analyzed for the allocation of productive zones by the content of chlorophyll "a". This is an area where the vegetation period weighted average phytoplankton chlorophyll "a" concentration in euphotic layer is greater than 1 mg/m3. These include coastal waters in temperate and low latitudes of the oceans, where there is the ascent of deep waters of the Antarctic circumpolar water between 50-70 degrees S, as well as waters of the seas of the Russian Federation, which were investigated by the scientists of VNIRO: the Caspian Sea; coastal zone of the South-Western part of the Black Sea; the western part of the Bering Sea; Okhotsk and White Sea (offshore, coastal waters of these seas, upwelling zones of islands, capes and underwater hills, front and gradient zones and others).
