The hypothetical exclusive economic zone at 200 M (in red) was calculated around southern Africa using LOTS. The Envelope of Arcs tools were applied on published territorial sea baselines and interpreted coastline from satelite images. The hypthetical extension of the juridical continental shelf under the United Nations Convention on the Law of the Sea Article 76 is indicated in orange. It outlines large sediment thickness as well as ridges and plateaus extending beyond the 200 M limit.
