Simulation of eddy-driven phytoplankton production in the Black Sea

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 computationally expensive multi-level models, without sacrificing much from the basics of the ecosystem dynamics.


Evolution of satellite derived mesoscale thermal patterns in the Black Sea
Sur, HI; Ilyin, YP (1997-01-01)
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 accomp...
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...
Applications of a 3-D numerical model to circulation in coastal waters
Balas, L; Ozhan, E (2001-06-01)
A three dimensional baroclinic numerical model which consists of hydrodynamic, transport and turbulence model components, has been applied to two test cases, including: the wind induced flow in a laboratory basin and tidal flow in a model rectangular harbor. The agreement between the physical and numerical model results is highly encouraging. Model has been implemented to Oludeniz Lagoon located at the Mediterranean coast of Turkey to simulate tidal and wind driven currents. M2 tide is the dominant tidal co...
Modeling the influence of hydrodynamic processes on anchovy distribution and connectivity in the black sea Karadeniz'deki hamsi dağılımı ve bölgeler arası bağlantısı üzerine hidrodinamik proseslerin etkisinin modellenmesi
Fach Salihoğlu, Bettina Andrea (2014-01-01)
Dispersal mechanisms of Black Sea anchovy larvae (Engraulis encrasicolus ponticus) across the Black Sea were studied with an individual based anchovy larvae model embedded in a Lagrangian model using surface currents calculated from daily dynamic height topography maps of altimeter data during a period of three years (2001-2003). Particles representing anchovy eggs were released at different sites during June to August and their movement was tracked over time. Drifters were advected for 36 days, representin...
Simulation of surface waves generated by a rapid rise of a block at the sea bottom
Şenol, Nalan; Aydın, İsmail; Department of Civil Engineering (2005)
A mathematical model is developed for investigating time dependent surface deformations of a hydrostatic water volume, when it is subjected to a sudden partial rise of the sea bottom. In the model, 2-dimensional, compressible, and viscous Navier-Stokes equations are solved by Marker and Cell (MAC) method. Variable mesh size in both horizontal and vertical directions with a staggered grid arrangement is used. Limited compressibility model is utilized for pressure. Various computational tests are done for the...
