Wanderlust World Wanderlust World The Caspian Sea defies simple classification. It's the world's largest inland body of water—larger than Japan, bigger than Germany—yet it's technically a lake (endorheic basin, no ocean outlet). Its statistics are superlative.
| Metric | Value |
|---|---|
| Surface area | ~371,000 km² (143,244 mi²) |
| Maximum depth | ~1,025 m (3,363 ft) |
| Average depth | ~211 m (692 ft) |
| Volume | ~78,200 km³ |
| Surface elevation | −28 m (−92 ft) below sea level |
| Shoreline length | ~7,000 km (4,350 mi) |
| Bordering countries | 5: Russia, Kazakhstan, Turkmenistan, Iran, Azerbaijan |
The Caspian's surface sits 28 meters below global mean sea level, making its shoreline the lowest land elevation on Earth (excluding the Dead Sea's shores, which are lower but not a sea-connected basin). This has profound implications:
Falling water levels (climate + upstream diversion), pollution (industrial, agricultural, oil), invasive species (comb jelly Mnemiopsis), sturgeon poaching, geopolitical tensions over resource division.
The Caspian is a planetary anomaly—an inland sea the size of a small ocean, below sea level, shared by five nations, holding energy wealth and evolutionary uniqueness. Its future depends on unprecedented cooperation.
