Ligurian Sea San Pietro Point () on the Coast of Italy. "On the North" The Ligurian Coast of Italy. In order to provide protection for the numerous cetacean (whales and dolphins; porpoises are not found in this part of the Mediterranean Sea) species in the Ligurian Sea the bordering countries established the sea as a SPAMI in 1999. The International Ligurian Sea Cetacean Sanctuary now covers covering territorial waters as well as high 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
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
