It is the shallowest part of the ocean basin, characterized by a gentle slope that averages about 0. The shelf varies dramatically in width; it can be a mere few kilometers wide off the steep coast of a Pacific island or stretch out for hundreds of kilometers in the Arctic Ocean or the Gulf of Mexico.
Global Variations in Continental Shelf Width Around the World
Claims are common in regions where the continental landmass continues for great distances underwater, such as the Arctic. Navigational and Ecological Considerations.
A coastal state can claim an extended continental shelf if its natural prolongation extends beyond that distance. This includes not just sand and gravel, but vast reserves of oil, natural gas, and minerals like manganese nodules.
Global Variations in Continental Shelf Width
This underwater landmass, extending from the coastlines of continents and islands, is not a sudden drop-off but a gradual, submerged extension of the land itself. This requires extensive geological and geophysical evidence submitted to the Commission on the Limits of the Continental Shelf (CLCS), a body of experts established by UNCLOS.
