Abstract

Climate change is one of the major challenge for Earth Systems in this century. Since the Industrial revolution, energy demands of countries has been rapidly increased which also causes an accelerated burning fossil fuels and increased greenhouse gases emission (GHG) into the atmosphere. Sea surface temperature (SST) is a pointer of the water temperature, which mainly related to sea surface layer and also plays an important role for keeping the energy balance between atmosphere and marine ecosystems. Various studies show that surface temperature of the inner seas surface temperature is affected by anthropogenic climate change. Gulf of Iskenderun is located in the southeast Mediterranean region of Turkey. The Gulf is important mainly for its industrial facilities and thermal power stations of Turkey. Due to the Suez Canal and strait of Gibraltar the gulf has also very important meaning for migration of the alien species into the Mediterranean Sea. To investigate the sea surface temperature (SST) change in the Gulf of Iskenderun over the period of 1982-2015 we used remote sensed data, which have 4x4 km high spatial and daily temporal resolution. This data collected from Copernicus Marine Services which based on satellites Advanced Very High Resolution Radiometer (AVHRR) Pathfinder Version 5.2 (PFV52). In the study period, the highest SST is determined in a JJA (June-July-August) season. The warmest region was the north is part of the bay. The SST change about 1.5º C in the study period.
