Under the United Nations Convention on the Law of the Sea (UNCLOS) the continental shelf is that part of the seabed over which a coastal State exercises sovereign rights with regard to the exploration and exploitation of natural resources including oil and gas deposits as well as other minerals and biological resources of the seabed. The legal continental shelf (consisting of the shelf, the slope and the rise) extends out to a distance of 200 nautical miles from the coastline, or further if the shelf naturally extends beyond that limit (as it does in Ireland's case).
