Evolution of satellite derived mesoscale thermal patterns in the Black Sea

Sur, HI
Ilyin, YP
Infrared image sequences covering the Black Sea are examined to investigate the evolution of mesoscale structures on the sea surface during the warm seasons of 1991-1993. Wind induced surface mixing and convective mixing are responsible for producing many features. The influence of seasonal evolution of the cold intermediate water (CIW) on the vertical and surface structures of eddies, including cold anticyclonic ones in summer, is examined. The annual variations of the short and long wave structures accompanying the meandering Rim Current are identified. The influence of river inputs to the western shelf area was traced more distinctly as evidence of the maximal outflow after the spring flood. Satellite data also helped in the interpretation of several peculiarities observed in vector distributions of the Acoustic Doppler Current Profiler (ADCP) observations resulting from sub-mesoscale dynamic features that were insufficiently resolved by the in situ data. The ADCP velocity maxima coincide with the temperature gradient of the Rim Current and the Vector directions correspond to the satellite derived flow configuration in April 1993 implying a close correlation between both measurements.

Simulation of eddy-driven phytoplankton production in the Black Sea
Oguz, T; Salihoğlu, Barış (2000-07-15)
A three dimensional, three-layer biological model is used to assess impact of eddy-dominated horizontal circulation on the spatial and temporal variations of plankton biomass in the Black Sea. Simulations are shown to exhibit patchy distributions of phytoplankton biomass as inferred from satellite images, and their intensities agree reasonably well with observations. Overall performance of the three layer model points to its potential capability as a practical alternative tool to more complex and computatio...
Effects of the North Sea Caspian pattern on surface fluxes of Euro-Asian-Mediterranean seas
Gündüz, Müge (American Geophysical Union (AGU), 2005)
The influence of the North Sea Caspian Pattern (NCP) on marine basins of the Euro-Asian-Mediterranean region (Mediterranean, Black and Caspian Seas) is investigated by making use of Empirical Orthogonal Functions (EOF) analysis. The effect of the NCP on surface fluxes of momentum and heat, as well as on curl and divergence of wind stress is evident in all of the studied basins. In particular, the Aegean and southern Black Sea heat fluxes are significantly affected by NCP. The processes underlying the demons...
Development of a numerical 2-dimensional beach evolution model
Baykal, Cüneyt (2014-01-01)
This paper presents the description of a 2-dimensional numerical model constructed for the simulation of beach evolution under the action of wind waves only over the arbitrary land and sea topographies around existing coastal structures and formations. The developed beach evolution numerical model is composed of 4 submodels: a nearshore spectral wave transformation model based on an energy balance equation including random wave breaking and diffraction terms to compute the nearshore wave characteristics, a ...
A baroclinic three dimensional numerical model applied to coastal Lagoons
Balas, L; Ozhan, E (2003-01-01)
An implicit barochnic unsteady three-dimensional model (HIDROTAM3) which consists of hydrodynamic, transport and turbulence model components, has been implemented to two real coastal water bodies namely, Oludeniz Lagoon located at the Mediterranean coast and Bodrum Bay located at the Aegean Sea coast of Turkey. M2 tide is the dominant tidal constituent for the coastal areas. The flow patterns in the coastal areas are mainly driven by the wind force. Model predictions are highly encouraging and provide favor...
Recent surficial shelf sediments of the Cilician Basin (Turkey), northeastern Mediterranean
Ediger, V; Evans, G; Ergin, M (1997-11-01)
The continental shelf of Mersin Bay forms the northwestern margin of the Adana-Cilician Basin; it extends from the Goksu delta (in the southwest) to the Seyhan-Tarsus-Ceyhan delta (in the northeast) and is narrower and steeper in the southwest than in the northeast.
