When we think of international boundaries, we imagine fences, walls, border crossings and survey markers. But some of the world's most important boundaries are completely invisible.
According to Guinness World Records, the longest maritime boundary is between Canada and Greenland, part of the Kingdom of Denmark, stretching approximately 2,697 kilometres (1,676 miles) through Arctic waters.
There are no fences, boundary stones or painted lines on the ocean. Instead, the boundary is defined through international agreements, charts and geographic coordinates, separating areas where neighbouring countries exercise rights over valuable marine resources.
Under international maritime law, coastal states can claim territorial seas extending up to 12 nautical miles and exclusive economic zones extending up to 200 nautical miles, subject to the rights of neighbouring countries.
These invisible boundaries help determine who can exploit offshore oil and gas, manage fisheries and develop marine energy resources.
A fascinating reminder that some of the world's most economically significant boundaries cannot be seen, walked or fenced, yet their precise location matters enormously.
