Abstract

The amount of water flowing into the seas and oceans has slowly but steadily increased in recent years, signifying a possible speeding up of the water cycle due to climate change. The detection of the water outflows and the exploitation of them are very important to the rational water management. Remote sensing techniques has been  proven  a  valuable  tool  for  the  detection  and  identification  of  submarine groundwater discharge-SGD (Submarine Groundwater Discharge). In this study   the island of Cephalonia in Ionian sea, Greece is considered as a case study. A  6 Km  sea   buffer zone around the island is studied using Landsat images. Submarine groundwater discharge has been detected through remote sensing methods and the results have been combined with the tectonism and hydrogeological conditions of the island. A quantitative analysis of temperature in the    buffer zone was   carried out. The   sea thermal anomalies in the same zone were also investigated.
