The fact that the Black Sea has unique physical and biogeochemical properties makes it difficult to use common models used to study many seas in the world. Considering this fact, an integrated modeling system has been developed that can be used in all seas surrounding Turkey, including the Black Sea. The components of the modeling system consist of a physical model that can predict currents and the thermodynamic variables of the seas, and a biogeochemical model developed to work in integration with it. For the first application of the developed modeling system among Turkish seas, the Black Sea, which is one of the most difficult seas to model in terms of biogeochemical and includes many processes especially in an oxygen-free environment, was deemed appropriate.The Black Sea has unique physical and biogeochemical properties. In order to understand the physical dynamics of the Black Sea correctly, small-medium scale eddy-front systems should be understood correctly. For this purpose, the Nucleus for a European Model of the Ocean (NEMO) model was adapted to the Black Sea. In the Black Sea NEMO model, Arakawa-C grid horizontal 3 km resolution and 75 vertical layers were used (Turkish Regional Seas Ecosystem Model,TURSEM). A complex biogeochemical model that tracks the cycles of C, N, P, Si, O, Fe, Mn, S and includes variable, quota-based stoichiometry of biological components is set for the Black Sea. The model is used to understand how mesoscale eddies and frontal features affect new production in the Black Sea. Physical and biogeochemical model validation was done by in situ and remote sensing measurements.

DYNAMICS OF THE TURKISH STRAITS SYSTEM :A NUMERICAL STUDY WITH A FINITE ELEMENT OCEAN MODEL BASED ON AN UNSTRUCTURED GRID APPROACH Gürses, Özgür; Özsoy, Emin; Department of Physical Oceanography (2016-4-15) This thesis presents the application of the finite element ocean model to the Turkish Strait System (TSS) which connects the two nearly-enclosed marginal water bodies of the Black and Mediterranean Seas through the narrow, non-straight and elongated Bosphorus and Dardanelles Straits and the Marmara Sea in between. The Turkish Strait System is a key gateway between the Black and the Mediterranean Seas and includes narrow channels where two-layer exchange flow develops. Being the only salt source in the Black...
SEASONAL TO DECADAL VARIABILITY IN THE PHYSICAL AND BIOLOGICAL PROPERTIES OF THE BLACK SEA AND LEVANTINE BASIN AS INFERRED FROM SATELLITE REMOTE SENSING Akpınar, Anıl; Fach Salihoğlu, Bettina; Department of Oceanography (2016-12-10) Black Sea and Eastern Mediterranean (Levantine basin) have gone through a number of documented changes in the recent decades. Recently acquired satellite data document rapid warming, increased sea level and decreased chlorophyll-a (phytoplankton) in the Black Sea and Levantine basin. Aim of this study is to address warming in the Black Sea and Levantine basin, as well as to investigate the phytoplankton response to changing environmental conditions at seasonal to interannual timescales. In the first part of...
Two-dimensional depth-averaged beach evolution modelling Baykal, Cüneyt; Ergin, Ayşen; Department of Civil Engineering (2012) In this study, a two-dimensional depth-averaged beach evolution numerical model is developed to study the medium and long term nearshore sea bottom evolution due to non-cohesive sediment transport 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 four sub-models: a nearshore spectral wave transformation model based on energy balance equation including random wave bre...
Petrography and mineral chemistry of the basaltic rocks and dykes from the Burunköy (Çorum) region, Turkey Atak Küçük, Aynur; Köksal, Fatma; Department of Geological Engineering (2014) Petrography and mineral chemistry of the basaltic rocks and dykes, which are outcropping in the Burunköy (Çorum) region, are discussed in the scope of this thesis. The studied rocks belong to the ophiolitic melange of İzmir-Ankara-Erzincan Suture Zone that were derived from the closure of northern branch of Neotethys. In the study area, the metamorphic rocks of Sakarya Composite Terrane tectonically overlies the ophiolitic melange units, and Upper Neocene sediments cover both units unconformably. The rocks ...
Estimation of carbon dioxide flux in shallow lakes in Turkey Kalvenas, Jennifer; Beklioğlu, Meryem; Department of Biology (2014) The role of Turkish shallow lakes as a sink or source of carbon from 44 shallow lakes sampled once from 2006 – 2012 over six degrees of latitude is analyzed in terms of spatial resolution. Two of the lakes (Eymir and Mogan) were sampled over the spring, summer, and fall seasons from 2006 – 2010 under dry and wet periods and analyzed for temporal resolution. An equation using pH, specific conductivity, wind speed, temperature, and acid neutralizing capacity (ANC) was used to determine CO2 fluxes (Trolle et a...
