Great Bahama Canyon Introduction

This map was created as part of a worldwide series of geologic maps for the U.S. Geological Survey's World Energy

25°0'0"N Project, available on CD-ROM and through the Internet. The goal of the project is to assess the undiscovered, technically Niños Knoll Bahama Escarpment recoverable oil and gas resources of the world. For data management purposes, the world was divided into eight energy Colón Seamount Niños Valley based on political boundaries and corresponding approximately to the economic regions of the world as defined

T Basin o n g by the U.S. Department of State. Region Six encompasses the Caribbean area, , and . u e e g Pinzón Knoll d o i f Q R t h r e o Quintero Knoll Geologic maps were compiled for South America on Open-File Report 97-470-D. Countries listed below are shown
