This article presents data from high-resolution shallow seismic profiles, side scan sonar, surficial sediment data for the sedimentary history, characterization and process-description of the Çeşme Ildır Bay. First, the effects of tectonism on the Gulf were examined from the literature. Tectonic and geological events occurring over the last 20000 years have been tried to be examined in the sea floor and in the water column. At the same time seagrass, coralligenous, marine habitats and abiotic structures (rock, mud, sand) were investigated. In addition, aquaculture activities are carried out in the region. In this study, the sea floor structure of Ildır Bay, an important aquacultural site around Karaburun Peninsula, was identified and mapped. The results of the neotectonism in the bay and the formations and differences in the seabed structures were analyzed and interpreted as a whole.
