Statistical Structure of Oceanic Fields in the Subarctic Frontal Zone

Abstract

Results of complex investigations of thermohaline structure, hydrochemical (Alk, pH, O_2, Ca, Mg and PO4^3-) and hydrobiological (biomass of mesoplancton) characteristics of water mass in Kuroshio subarctic frontal zone are presented. For the data processing standard statistical methods including calculation of moments and histograms, factor and correlation analysis were used. Most variables correspond to the law of normal distribution. About 70% of the total data dispersion gives threedimensional spatial variability of frontal zone characteristics. Compact description of the three-dimensional hydrochemical frontal zone structure has been obtained through a regression model, estimations for correlation bonds among individual parameters and spatial coordinates have been made.
