Identification of potential areas for presence of submarine springs in the persian gulf on the coasts of Bushehr province using thermal data of Landsat 8

In order to determine potential areas of submarine springs on the coast of Bushehr province, Sea Surface Semperature (SST) around Bahrain and the coasts of Bushehr province, according, to atmospheric correction coefficients and the relations for thermal band 10 of Landsat 8 in four months 2016 was mapped using ArGIS and ENVI software. After extracting the estimate temperature submarine springs of Bahrain, six springs was determined as a control. The temperature of the springs was estimated 16.54, 18.52, 17.29, 15.97, 17.73, and 15.83°C in the image of February. Matching coastlines estimated temperature of Bushehr province with the mean control temperature (16.98°C), several regions were identified as potential areas of submarine springs, including Asaloyeh-Nayband bay, a large part of the coastline between Bandar Dayer to Mond river, around the village of Kalat, east-west of Bushehr, between Shif island and Heleh river, Bandar Rig, around Bandar Ganaveh, and between Hendijan and Bandar Deylam. Thermal anomalies with less 100 meter diameter to water bodies probably are less important than wider anomalies; therefore using the images with moderate resolution, such as Landsat 8, may be more important than high resolution images for detecting the broad and significant anomalies, especially in terms of time and cost. The images may use as a preliminary screening test for the early identification of potential areas of the submarine springs.
