Гидрохимические исследования на разрезе “Кольский меридиан” с использованием изотопного трассера d18O

Abstract

The results of hydrochemical studies at 10 stations of the transect “Kola meridian” opencast performed on the expedition NIS “Dalnye Zelentsy” in April 2019, where hydrochemical studies of phosphate phosphorus, nitrate nitrogen and silicon were performed, are presented. To analyze the data, a technique using the 18O isotope tracer was used. The measure of production and destruction of selected nutrients was determined by the author's method. Two alleged foci of phytoplankton activity were identified: areas in the region of the ice edge in the north of the section and in the waters of the Murmansk coastal course. The state of the waters in the section is defined as late spring.
