Ionian Sea is the arm of the Mediterranean Sea between southern Italy and Greece.
The Ionian sea is bounded by the western shores of Greece, south Albania, Sicily and the southern coast of Italy.
To the north it joins the Adriatic Sea through the Strait of Otranto.
The Ionian Sea is the deepest basin in the Mediterranean, 5,020 m. at its deepest point southwest of the Peloponnese, with a riven coastline.
The Ionian Sea is a tectonic rift basin, formed roughly seven million years ago in the area where the African continental plate is being subducted beneath the Eurasian one. The area took on its present geomorphological shape about 2.5 million years ago.
The main ports on the Ionian Sea are those of Patras, Igoumenitsa and the Ionian Islands on the Greek side, and the ports of Catania and Taranto in Italy.
