Outer Continental Shelf limits greater than 200 nautical miles but less than either the 2,500-meter isobath plus 100 nmi or 350 nmi are defined by a line 60 nautical miles (111.1 km; 69.0 mi) seaward of the foot of the continental slope or by a line seaward of the foot of the continental slope connecting points where the sediment thickness ...
