Abstract
Purpose. To solve the many practical problems it is necessary to use vertical distribution of hydrological characteristics of the marine environment and mainly the water temperature. Today there isn’t an easy way to get a contact data for evaluation of the vertical distribution. Main purpose of this work is to estimate an ability of using of satellite data for calculation of vertical distribution of water temperature in the Black Sea, analysis and evaluation of its applicability. Data & Methods. As source data for the calculations we used climatic, contact and satellite data. Methods of calculations are based on the identification of statistical dependencies between the adjacent horizons of the vertical distribution of water temperature in the Black Sea for climate data, they are used in predictive equations. Results. Calculations show statistically significant results in the spring and autumn periods. For the winter period of the year, it is needed a further development of the method with additional parameters in regression equations. Correlation coefficient (r) between the values of contact measurements and values that were calculated by satellite data of water temperature is between 0.89 – 0.99. Weak correlation between actual and calculated values was observed only for large temperature gradient in the thermocline zone. So, the ability to calculate the vertical distribution of water temperature on standard depths up to 50 m on the basis of satellite data with proposed method is proved (on example of the Black Sea).
