UNCLOS Maritime Baselines & Exclusive Economic Zones
"Invisible 200-nautical-mile boundaries enclosing 38% of the world's oceans under sovereign resource rights"
UNCLOS codified the modern law of the sea: Territorial Sea (12 nm), Contiguous Zone (24 nm), and Exclusive Economic Zone (200 nm). Archipelagic states (Indonesia, Philippines) can draw straight baselines connecting outer island reefs.
Historical Genesis & Geopolitics
Replaced the ancient 'cannon-shot rule' (3 nautical miles) with mathematical geodesics radiating from coastal baselines, granting coastal nations exclusive fishing and seabed mineral rights.
Cartographic Mechanism & Impact
Invisible cartographic buffers carved 138 million km² of ocean into national economic zones, triggering intense geopolitical battles over artificial islets in the South China Sea.
