Abstract
The systematic and random errors of reconstruction of the climatic variability of temperature and salinity in the Black Sea are analyzed on the basis of the archival deep-water data accumulated in 1955–1998. It is shown that, in order to describe the space variability of large-scale deep-water characteristics of the temperature fields with reasonable accuracy, one can use both the data of standard hydrological measurements and the CTD data. In this case, the systematic errors are practically indistinguishable against the background of random errors whose characteristic level is equal to 0.03°C. The random errors of evaluation of salinity are as large as about 0.04‰ and the corresponding systematic errors are not distinguished. The available archive of the data of deep-water measurements enables one to select space structures with characteristic dimensions of 2° in the latitudinal and longitudinal directions with temperature and salinity inhomogeneities exceeding 0.0035°C and 0.004‰, respectively. This is sufficient to confirm the fact of elevation of the bottom temperature in the central part of the sea is by about 0.015°C as compared with its peripheral parts.
