COASTAL EUTROPHICATION AND HYPOXIA UNDER FOCUS: REDOX DEPENDENT BENTHIC NUTRIENT FLUXES ACROSS SEA BOUNDARIES IN THE NORTHEASTERN MEDITERRANEAN AND MARMARA SEA
Akçay, İsmail; Yücel, Mustafa; Department of Oceanography (2022-2-8)
Seafloor biogeochemistry can dramatically shift in response to deoxygenation and eutrophication-driven organic carbon production. In such conditions, biogeochemical cycling of key nutrients can be highly coupled to oxygen ...
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

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...
EFFECT OF TEMPERATURE ON THE OCCURRENCE OF THREE MOST ABUNDANT SMALL PELAGIC FISH SPECIES IN THE SOUTHERN BLACK SEA
Bilir, Batıkan; Gücü , Ali Cemal; Department of Marine Biology and Fisheries (2019-10-04)
It is known that the temperature change in water resulted by the strength and direction of cold winds varying from year to year has an effect on the distribution of small pelagics which have yearly migration cycles in semi...
DISTRIBUTION OF CETACEAN AND THEIR FORAGING HABITATS IN THE BLACK SEA
Başkır, Saba; Gücü , Ali Cemal; Department of Chemical Oceanography (2019-10-04)
Cetacean hunting was banned in Turkey in 1983. In the following decades, as the ecological shifts in the Black Sea occur, over-increase in the cetacean populations were hypothesized as the cause of the decline in economica...
INVESTIGATING MESOSCALE PHYSICAL PROCESSES FOR VERTICAL AND HORIZONTAL TRANSPORT IN THE BLACK SEA WITH THE IMPLEMENTATION OF A HIGH-RESOLUTION CIRCULATION MODEL
Sadighrad, Ehsan; Salihoğlu , Bettina Fach; Department of Oceanography (2019-9-24)

INVESTIGATING PELAGIC FISH LARVAL DISPERSAL AND ECOLOGIC CONNECTIVITY IN THE BLACK SEA USING LAGRANGIAN DRIFTER MODELING
Çağdaş, Bulut; Fach Salihoğlu, Bettina; Department of Oceanography (2019-9-24)
In order to understand fish population dynamics, understanding the physical interaction of the current systems with pelagic fish larvae is necessary. Using a Black Sea circulation model output to undertake Lagrangian drift...
INVESTIGATING MARINE MICROBIAL REACTIONS USING NOVEL APPROACHES: GENETICS AND BIOGEOCHEMISTRY
Deliceırmak, Selin; Salihoğlu, Barış; Arkın, Sinan; Department of Marine Biology and Fisheries (2019-5-28)
Despite the many important roles, they play, bacteria are one of the least known components of the marine biogeochemical cycles. In order to determine the temporal dynamics of the species composition, and active metabolism...
ELUCIDATING THE IMPACT OF DISPERSAL ON THE PERSISTENCE OF SMALL COLONIES OF ENDANGERED MEDITERRANEAN MONK SEAL
Kurt, Merve; Gücü , Ali Cemal; Department of Marine Biology and Fisheries (2019-02-01)
Evaluation of the breeding and resting habitats indicated that the most prominent threat is the construction of industrial infrastructure; it is followed by tourism, and construction of houses and roads. The consequences o...
ESTIMATING THE EFFECT OF KRILL ON THE SOUTHERN OCEAN ECOSYSTEM FUNCTIONING
