Andreas Miaoulis was the first Hydrographer, and discovered a reef in the Ioanian sea which was named after him. He published papers concerning the tidal currents in the Euripus Strait, as well as those predicted for the new canal at the Isthmus of Corinth.
Andreas Miaoulis was born on the island of Hydra in 1830. He was the son of Antonios Miaoulis and a relative of Andreas Miaoulis, the great Greek admiral during the Greek war of Independence.
He attended the Navy school and was commissioned as a sub lieutenant in 1854. He was on of the first Greek officers to study hydrography, an ignored subject and that’s why he was nicknamed “the teacher”. His obsession with the subject resulted in his dismissal but in 1866, when the importance of hydrography became apparent, he was recalled to active duty. As captain of the ship Methoni he augmented his knowledge on the subject by observing the measurements made by the British hydrographer Arthur Mansell in the Euripus Straits.
Hydrography is the science of surveying and charting bodies of water, such as seas, lakes, and rivers. It includes the positioning and identification of things such as wrecks, reefs, structures, navigational lights, marks and buoys and coastline characteristics.
