Euripus Strait

The Euripus Strait (Greek: Εύριπος, pronounced ), is a narrow channel of water separating the Greek island of Euboea in the Aegean Sea from Boeotia in mainland Greece. The strait's principal port is Chalcis on Euboea, located at the strait's narrowest point.

The strait is subject to strong tidal currents which reverse direction approximately four times a day. Tidal flows are very weak in the Eastern Mediterranean, and the strait is a remarkable exception. Water flow peaks at about 12 km/hour, either northwards or southwards, and lesser vessels are often incapable of sailing against it. When nearing flow reversal, sailing is even more precarious because of vortex formation.

The Swiss scholar Francois-Alphonse Forel helped to solve this enigma owing to his study of limnology and the discovery of the seiche phenomenon. But the complete solving of the problem is due to the Greek D. Eginitis, director of the Athens Observatory, who published his conclusions in 1929.

Famous quotes containing the word strait:

    We approached the Indian Island through the narrow strait called “Cook.” He said, “I ‘xpect we take in some water there, river so high,—never see it so high at this season. Very rough water there, but short; swamp steamboat once. Don’t paddle till I tell you, then you paddle right along.” It was a very short rapid. When we were in the midst of it he shouted “paddle,” and we shot through without taking in a drop.
    Henry David Thoreau (1817–1862)
