About Ionian Sea, facts and maps

Ionian Sea, Latin Mare Ionium, Italian Mare Ionio, part of the Mediterranean Sea, lying between Albania (northeast), Greece (east), Sicily (southwest), and Italy (west and northwest).. The Sea was the location of the famous naval battle between Octavian and Marc Antony known as The Battle of Actium, a war fought in 31 BC, and is also famous for the hero from Ancient Greek mythology named Odysseus, who was from the island of Ithaca.

The Greek Blue colour refers to the sky as much as it does to the sea. This glorious blue colour is due partly to the reflection of the blue skies and partly to the fact that the sea does not contain large quantities of solid matter such as plankton, mud and dust floating in the water.

The International Hydrographic Organization defines the limits of the Ionian Sea as follows:

On the North. A line running from the mouth of the Butrinto River (39°44’N) in Albania, to Cape Karagol in Corfu (39°45’N), along the North Coast of Corfu to Cape Kephali (39°45’N) and from thence to Cape Santa Maria di Leuca in Italy.
On the East. From the mouth of the Butrinto River in Albania down the coast of the mainland to Cape Matapan.
On the South. A line from Cape Matapan to Cape Passero, the Southern point of Sicily.
On the West. The East coast of Sicily and the Southeast coast of Italy to Cape Santa Maria di Leuca.

The Ionian Sea (Greek: Ιόνιο Πέλαγος, Iónio Pélagos [iˈonio ˈpelaɣos]; Italian: Mar Ionio [mar ˈjɔːnjo]; Albanian: Deti Jon [dɛti jɔn]) is an elongated bay of the Mediterranean Sea. It is connected to the Adriatic Sea to the north, and is bounded by Southern Italy, including Calabria, Sicily, and the Salento peninsula to the west, southern Albania (and western Apulia, Italy) to the north, and the west coast of Greece, including the Peloponnese.

All major islands in the sea, which are located in the east of the sea, belong to Greece. They are collectively named the Ionian Islands, the main ones being Corfu, Kefalonia, Zakynthos, Lefkada, and Ithaca.

There are ferry routes between Patras and Igoumenitsa, Greece, and Brindisi and Ancona, Italy, that cross the east and north of the Ionian Sea, and from Piraeus westward. Calypso Deep, the deepest point in the Mediterranean at 5,109 m (16,762 ft), is in the Ionian Sea, at 36°34′N 21°8′E. The sea is one of the most seismically active areas in the world.

Why is the Ionian Sea so salty?

The high water temperature (up to 83°F) causes a high rate of evaporation, and the sea’s salinity is also in part due to its remoteness from land: it receives no fresh-water inflow.

Ionic dialect, any of several Ancient Greek dialects spoken in Euboea, in the Northern Cyclades, and from approximately 1000 bc in Asiatic Ionia, where Ionian colonists from Athens founded their cities. Attic and Ionic dialects together form a dialect group.
