Abstract

To characterize and compare various coastal areas of the seas including river plumes and water mixing zones in straits a method for arranging them on a special diagram (Water Type Diagram) is proposed. It is possible to allocate here zones of waters similar in composition to oceanic waters as well as waters with extra suspended matter and/or extra dissolved organic matter. At the same time this diagram allows to compare processes in waters of different trophicity. The paper presents calculations based on passive optical sounding data obtained from board a ship for the open ocean, the Black Sea, the Kerch Strait, the Kara Sea, and the Rio Grande River plume off the Brazilian coast of the Atlantic Ocean.
