The region of Mani peninsula represents the southernmost part of continental Europe, forming a massive carbonate outcrop in the prolongation of the Taygetos Mountain, and hosts one of the largest and most spectacular karstic systems of Europe, the Cave of Diros. This karst system discharges in the sea and thermal infrared remote sensing proved its capability in monitoring temperature field. The purpose of this study is to evaluate the use of Landsat Thematic Mapper (TM) data for mapping and indicating temperature differences between the sea and the underground fresh water which discharges towards the sea, by creating a cold water plume. Several different points of groundwater discharge have been detected and mapped not only strictly along the coastal zone of the Mani peninsula, but as far as 1500 m from the coast as well. Moreover, following such modeling techniques their temperatures have been estimated. These points of discharge are aligned along two main orientations that are tectonically controlled. The major one is NNW-SSE trending and a secondary is E-W trending. Overall, the karstification process is highly controlled by the tectonic lineaments. The largest quantities of freshwater source from the massive carbonate mass of the Taygetos Mt and follow a NNW-SSE trending path.
