| Abstract: | This paper reports on the results of determining the chlorine, potassium, calcium and sulphur concentrations obtained by X-ray fluorescence (XRF) during the 37th cruise of the R/VAkademik Vernadsky in the tropical Atlantic. The determination accuracies for the ratios of K/Cl, Ca/Cl, and S/Cl were 0.45, 0.58, and 2.5%, respectively. As follows from the data obtained, the variations of these ratios exceed the accuracy of the measurements at all stations, and they are connected with the structural features of the hydrochemical fields.Translated by Mikhail M.
