Table 4. Estimates of "Undiscovered Recoverable" Resources, or 

 Predicted Potential Yields from the Offshore out to Depths of 

 650 Feet (200 m) [Source: Reference 3) 



1. Those economic resources not yet discovered which are estimated 

 to exist in favorable geologic environments. 



2. Statistical Mean between 95% and 5% probabilities. 



3. Additional estimates for deeper areas -- 650 to 8,200 



feet (200-2,500 m) -- shown in parentheses for four offshore 

 areas.
