The air-sea exchange in the Black Sea is revisited in the paper on the base of data provided from the ECMWF atmospheric re-analysis for the period 1979-1993. Climatological characteristics of analysis data are compared against available climatic data, demonstrating quite a good consistency. Several drawbacks are found: too low temperatures in the easternmost part of the sea, too low dew point temperature and slight underestimation of precipitation. However, the seasonal and inter-annual oscillations are resolved correctly, as well as the horizontal patterns of air-sea exchange. The shallow penetration of thermal signal in the Black Sea is well detected by the very small heat transports inferred from the ECMWF data. Thus, the conclusion is that the analysis 'sees' quite well the major thermal peculiarity of the Black Sea associated with its extremely small thermal inertia caused by the specific stratification.

Seasonal Changes in the Composition and Abundance ofZooplankton in the Seas of the Mediterranean Basin Kovalev, Av; Mazzocchı, Mg; Toklu Alıçlı, Benin; Skryabın, Va; Kıdeyş, Ahmet Erkan (2003-01-01) Seasonal changes in the composition, abundance and biomass of zooplankton in the seas of the Mediterranean basin (the Mediterranean, Black and Azov seas) have been reviewed using our own data and data from the literature. In the deep-water central regions of the seas, the seasonal cycle of zooplankton abundance is characterised by one maximum occurring in spring or summer. In the coastal regions, two to three peaks (spring, summer and autumn) exist for the zooplankton abundance. The amplitude of seasonal fl...
Climate variability and deep water mass characteristics in the Aegean Sea Georgiou, S.; Mantziafou, A.; Sofianos, S.; Gertman, I.; Ozsoy, E.; Somot, S.; Vervatis, V. (2015-01-15) The main objective of this study is to investigate the variability of the thermohaline characteristics of the deep-water masses in the Aegean Sea and the possible impact of the regional atmospheric forcing variability by analyzing the available oceanographic and atmospheric datasets for the period of 1960-2012. During this period the variability of the deep water characteristics of the Aegean sub-basins is found to be very large as well as the diversity of the deep water characteristics among the sub-basins...
Convection in the Black Sea during cold winters Ivanov, LI; Backhaus, JO; Ozsoy, E; Wehde, H (2001-11-01) We investigate the effects of initial conditions and atmospheric forcing on the penetration depth of winter convection in the strongly stratified environment of the Black Sea. The amount of Cold Intermediate Water (CIW) formed annually in the Black Sea, and the amount entrained into the euphotic zone from below, largely depend on the convective activity in the cold season. Seasonal thermohaline evolution of the mixed layer has been simulated using a one-dimensional mixed layer model driven by the ECMWF mete...
Interannual variability of the early summer coccolithophore blooms in the Black Sea: impacts of climatic factors Cokacar, T; Oguz, T; Kubilay, N (2003-08-06) Interannual variability of the early summer (May-June) coccolithophore blooms within surface waters of the Black Sea was studied by means of satellite-based bio-optical observations. The performance of two coccolithophore detection algorithms were tested for Black Sea conditions, and were found to provide comparable spatial patterns consistent with the corresponding true color images. An analysis of six, year-long OCTS and SeaWiFS imagery from 1997 onwards points to the presence of a major phytoplankton blo...
Ventilation of deep waters in the Adriatic and Ionian Seas following changes in thermohaline circulation of the Eastern Mediterranean Manca, Beniamino B.; Ibello, Valeria; Pacciaroni, Massimo; Scarazzato, Paolo; Giorgetti, Alessandra (2006-07-27) Hydrographic measurements obtained in March-April 2002 indicate a new ventilation of the deep layers in the Adriatic and Ionian Seas, following abrupt changes in the thermohaline circulation of the eastern Mediterranean observed since the beginning of the last decade. The water masses that reside in the Southern Adriatic basin were renewed by open ocean winter convection of water with potential density excess (sigma(theta)) > 29.18 kg m(-3) at depths 600 to 800 m and by a vein of still denser (29.26 kg m(-3...
