GEOCHEMISTRY OF DEEP-SEA HYDROTHERMAL VENT FLUIDS FROM BROKEN SPUR, RAINBOW AND LOST CITY HYDROTHERMAL VENT FIELDS, MID-ATLANTIC RIDGE
Sevgen, Serhat; Yücel, Mustafa; Department of Oceanography (2021-5-21)
Mid- Atlantic Ridge (MAR) is a very special tectonic environment which contains compositioanlly distinct hydrothermal vent fields as a result of its slow spreading character. Considering the increasing efforts on understan...
COASTAL VULNERABILITY ASSESSMENT FOR MERSIN AND İSKENDERUN BAYS, NORTHEASTERN MEDITERRANEAN
Aykut, Fahri; Tezcan, Devrim; Department of Oceanography (2021-2)
Coasts are sensitive and dynamic areas against natural influences such as waves, winds, currents, and tides. Pressure of human activities also accelerate the change of coasts. Climate change and global sea level rise are o...
Mitochondrial and nuclear dna phylogeographies for two botryllid ascidian species from the north-eastern mediterranean sea
Öztürk, Esra; Karahan, Arzu; Department of Marine Biology and Fisheries (2020-10-22)
With approximately 3000 species, ascidians are the largest tunicate group in the world seas. Botrylloides belongs to the genera of the worldwide spread Botryllid ascidians. In the Eastern Mediterranean coasts, a total of s...
A Study on possible variant forms of anchovy in the black sea
Şahin, Ezgi; Gücü, Ali Cemal; Department of Marine Biology and Fisheries (2014)
The anchovy in the Black Sea is a commercially important fish source for Turkey, which is represented by two different subspecies in the basin. Spawning and feeding occurs in northern coasts where food supplies are more ab...
Current distribution of the small pelagic fish populations in the North Eastern Levantine Sea in relation to environmental conditions and predicting the impacts of temperature rise on their future distributions
Sakınan, Serdar; Gücü, Ali Cemal; Department of Marine Biology and Fisheries (2014)
Stocks of traditionally targeted fish species are in decline in the north eastern Levant Sea due to overfishing during recent decades, while catch statistics show a simultaneous increase in landings of commercially less va...
Stock assessment of the Black Sea anchovy
Tutar, Özge; Gücü, Ali Cemal; Department of Marine Biology and Fisheries (2014)
The Black Sea anchovy (Engraulis encrasicolus) is economically the most important fish species in Turkey since it provides 60% of the total fish catch. The Turkish fleet catches 90% of the anchovy stock in the Black Sea du...
Numerical simulations of eutrophication processes in İzmir Bay with a coupled three dimensional eco-hydrodynamic model
Yelekçi, Özge; Fach Salihoğlu, Bettina Andrea; Ibello, Valeria; Department of Physical Oceanography (2013)
A three dimensional time-dependent coupled ecosystem model is applied to İzmir Bay for the first time. Delft3D modelling suite’s FLOW and ECO modules are adapted and tuned for the region. A reference model with a time fram...
Assessment of the trophic status of the Mersin bay waters, Northeastern Mediterranean
Kaptan, Mehmet Salih; Tuğrul, Süleyman; Department of Chemical Oceanography (2013)
Identifying the spatial and temporal variability of eutrophication related indicators such as Chlorophyll-a (Chl-a), oxygen saturation (DO%), dissolved inorganic nitrogen (DIN) and total phosphorus (TP), as a measure of th...
Nonlinear dynamics of the Black Sea ecosystem and its response to anthropogenic and climate variations
Akoğlu, Ekin; Salihoğlu, Barış; Department of Marine Biology and Fisheries (2013)
The main objective of this research is to i) provide a quantitative understanding of the changes in the Black Sea ecosystem between 1960 – 1999, ii) to identify its food web dynamics including the infamous anchovy – Mnemio...
Monthly changes in primary and bacterial productivity in the North – Eastern Mediterranean shelf waters
Yücel, Nebil; Uysal, Zahit; Department of Marine Biology and Fisheries (2013)
Within the context of this thesis, it was aimed to compare monthly changes in primary and bacterial production rates of eutrophic shelf waters with those of nutrient impoverished oligotrophic open waters taking into consid...
Analyses of atmospheric and marine observations along the Turkish coast
Tutsak, Ersin; Özsoy, Emin; Department of Physical Oceanography (2012)
Time series and spectral analyses are applied to meteorological data (wind velocity, air temperature, barometric pressure) and sea level measurements from a total of 13 monitoring stations along the Turkish Coast. Analyses...
Evaluation of the demersal fish assemblages of the northeastern levant sea
Ok, Meltem; Gücü, Ali Cemal; Department of Marine Biology and Fisheries (2012)
Ecosystem-level changes have taken place in the Mediterranean Sea over the last decades due to both anthropogenic interferences and natural perturbations. Compared to the western Mediterranean Sea, influences of these fact...
A Coupled modelling attempt of hydrodynamics and ecosystem of northern levantine basin
Aydoğdu, Ali; Salihoğlu, Barış; Cannaby, Heather Anne; Department of Physical Oceanography (2012)
A three-dimensional ocean model, ROMS, has been utilized to simulate the hydrodynamics and the ecosystem dynamics of the Northern Levantine Basin circulation. The model is one-way nested inside a coarser resolution Mediter...
Reconstruction of SeaWİFS chlorophyll data for the Black Sea
Sancak, Serkan; Oğuz, İ. Temel; Department of Physical Oceanography (2011)
SeaWiFS was collecting ocean color data since 1997. This means chlorophyll-a data for more than ten years. Since, SeaWiFS Chl-a data is validated for Black Sea this data set can be used for analysis. Nevertheless, the data...
The impact of climate variability on the physical properties of the Black Sea for the period 1971 – 2001
Korkmaz, Muhteşem Akif; Salihoğlu, Barış; Cannaby, Heather Anne; Department of Physical Oceanography (2011)
Deep ventilation of the Black Sea is inhibited by a sharp salinity gradient within the upper water column, resulting in a shallow anoxic interface at around 100 – 200 m depth. Understanding biological and chemical processe...
Temporal and spatial changes in the abundance and biomass of pico (heterotrophic bacteria & synechococcus) and nanoplankton (flagellates) of the Mersin Bay – relationships with ambient physical, chemical and biological parameters
Gazihan Akoğlu, Ayşe; Uysal, Zahit; Department of Marine Biology and Fisheries (2011)
The eastern Mediterranean has been known as the most oligotrophic water body among the worlds oceans and as a result of limited nutrient inputs from terrestrial sources primary productivity and plankton succession are rest...
