Sigsbee Deep

The Sigsbee Deep (Mexico basin in the U. S. Board on Geographic Names Advisory Committee on Undersea Features Gazetteer) is a roughly triangular basin that is the deepest part of the Gulf of Mexico named for Charles Dwight Sigsbee. There is some confusion of names that apply to the basin or a particular point in the basin, with both being found in technical and popular literature applying to both basin and the coordinates.
