Written accounts from the ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its salinity and large size. The seabed in the south reaches 1,023 m (3,356 ft) below sea level, which is the second-lowest natural non-oceanic depression on Earth after Lake Baikal (−1,180 m or −3,870 ft). These lead to horizontal differences in temperature, salinity, and ecology. Two deep basins form its central and southern zones. Its main freshwater inflow, Europe's longest river, the Volga, enters at the shallow north end. Its gross coverage is 386,400 km 2 (149,200 sq mi) and the surface is about 27 m (89 ft) below sea level. The sea stretches 1,200 km (750 mi) from north to south, with an average width of 320 km (200 mi). It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It covers a surface area of 371,000 km 2 (143,000 sq mi) (excluding the highly saline lagoon of Garabogazköl to its east), an area approximately equal to that of Japan, with a volume of 78,200 km 3 (19,000 cu mi). An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of West Asia. The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea.
