Satellite indicators of sea surface temperature, chlorophyll-a and the diffuse attenuation coefficient for the Izmir Bay: A study for descriptive and temporal evaluation
Keywords:Descriptive, trend, physical and optical properties, Izmir Bay
One of the most important challenge in the world is the climate change causing warming of oceans and its direct and indirect impacts on ecosystems. This fact makes it important to have and utilize regular data sets to increase understanding. In this study, it is aimed to understand the descriptive properties of outer Izmir Bay by using alternative data sets from satellite technology. Remotely sensed data sets of the sea surface temperature, chlorophyll-a and attenuation coefficient through satellite technology were analyzed over a long time period, between 01/2004 and 12/2021. Results showed stable properties of these variables and significantly weak increasing trend in chlorophyll-a and attenuation coefficient. Even though no significant trends were detected in sea surface temperature, months from winter to summer showed significant increasing trend for the temperature. Seasonal warming trend can be the cause to successful settlement of warm-water species in Izmir Bay, as it is maybe the case in other parts of the Mediterranean Sea.
