Ligurian Sea Ligurian Sea The Ligurian Sea (; ) is an arm of the Mediterranean Sea, between the Italian Riviera (Liguria) and the island of Corsica. The sea is theorized to be named after the ancient Ligures people. The sea borders Italy as far as its border with France, and the French island of Corsica. In the east the sea borders the Tyrrhenian Sea, while in the west it borders the Mediterranean Sea proper. Genoa is the most prominent city in the area. The northwest coast is noted for its scenic beauty and favourable climate. The Gulf of Genoa is its northernmost
Metre sea water absolute pressure is used in most computations, particularly for decompression and breathing gas consumption but depth is measured by way of hydrostatic pressure. In metric units the ambient pressure is usually measured in metres sea water (msw}, and converted to bar for calculations. In US customary units ambient pressure is normally measured in feet of sea water (fsw), and converted to atmospheres absolute or pounds per square inch absolute (psia) for decompression computation. Feet and metres sea water are convenient measures which approximate closely to depth and are intuitively simple to grasp for the diver, compared to the options of
