Table 1 . Ocean Energy Farm : summary of site selection criteria. 

 BIOLOGICAL REQUIREMENTS/LIMITATIONS 



1. 20° maximum mean surface temperature 



2. a. 3-5 ^tg-at/liter nitrate (minimum) 

 b. 10-15 jug-at/liter nitrate (optimal) 



3. a. 25 cm/sec (0.5 kn) current maximum OFEF {> 25 cm/sec sustained current 



causes plants to approach horizontal at substrate depth) 



b. Optimal: 10 cm/sec (0.2 kn) 



c. Minimal: 4 cm/sec (0.08 kn) 



ENGINEERING LIMITATIONS/REQUIREMENTS 



1. a. 0.5-m/sec (1-kn) current at substrate depth (Phase 1 operational current) 

 b. Maximum 1.5-m/sec sustained current design limitation 



2. a. Avoid storm-force winds (greater than 25 m/sec) (locate in area of least storm 



probability) 

 b. Minimize gale-force winds (greater than 17-m/sec, 5.5-meter waves) 



3. a. Maximum significant wave height 1 1 meters (35 feet) (design for Pliase 1 test 



module) 



b. Extreme wave height 19 meters (63 feet) (extreme design wave) 



c. Minimum mean wave height 1 meter (required for upwelling system) 

 Optimal wave height 2-3 meters (for upwelling system) 



ECONOMIC 



1. Moored substrate - maximum depth 600 meters (Phase 3) 



2. Proximity to research and support facihties 



Phase 1 : 32-kilometers maximum (2-hour transit time) 



GEOPOLITICAL 



1 . Avoid traditional sea lanes and submarine transit zones 



2. Locate outside claimed economic and territorial zones 



(probably 320-kilometer zones will be adopted - needs international clarification)
