Mean multiannual temperature regime of the surface water layer in the near-shore regions of the White Sea

The mean multiannual temperature regime of the surface water layer in the near-shore regions of the White Sea is analyzed from the data obtained at the VNIIGMI-MTsD (Obninsk). A function describing the seasonal temperature trend in the surface layer was found by the method previously used for an analysis of the Onega and Ladoga lakes. The method is based on the nonlinear approximation of the field observations by a function composed of a combination of exponents with coefficients to be calculated. Explicit seasonal dependences of the mean temperature of the surface water layer in the White Sea were obtained for nine near-shore stations. The root-mean-square deviations of the measured values of the water temperature were estimated.
