Type definitionof vertical chlorophyll distribution in contrasting zones of the mediterranean sea

摘要

The analysis of vertical distribution of chlorophyll concentration (CHL) in deep-water regions of the Mediterranean Sea was carried out on the basis of historical data received during 1979 - 1987 in western and eastern parts of the sea. It was shown that for a deep-water part of the Mediterranean sea presence of two types of a vertical structure: one-modalk, satisfactorily described by the Gaussian curve, and quasi-homogeneaus uniform distribution from a surface up to certain depth and subsequent downturn of concentration up to a minimum was characteristic for various regions and seasons. Parameters describing both types of vertical CHL distribution in the Mediterranean Sea in researched period were computed. Type of a vertical CHL profile and the parameters, describing its form, in each particular case in general corresponds to character of vertical distribution of pigment in moderate latitudes with expressed seasonal variability.
