Open Water Dives
General Open Water Considerations
D0. Review Surface support checklist
D1. Review outside Carriacou Sealab checklist
• Dive one swim under Carriacou Sealab and enter moonpool
D2. Review inside habital checklist
• Post-dive procedures
• Log dive (instructor signs logbook)
Life Support Techniques
• A) Electric Power.
Gasoline or diesel generator.
Solar, wind, wave, current, salinity, ocean thermal and geothermal.
• B) Atmosphere regeneration.
O2 Replenishment Techniques.
-Constant vent from surface compressor.
-High pressure air or O2 cylinders.
-Chemical regeneration using either Sodium & Potassium Superoxides or Chlorate Candles.
-Liquid O2 (Dewar flask, a vacuum flask to hold liquid gases).
-Biological production of O2 using algae.
Sensors to maintain proper gas mixes.
-O2 20-22% by volume.
-CO2 .5 % to 1 % maximum (otherwise increased respiratory rate , view ports fogging).
• C) Water.
-stored in bottles, storage tanks, flexible bladder (Aquanauts originally slept on water beds which doubled as an emergency water supply) or outside the habitat.
-Distilled at site by reverse osmosis, flash distillation (Multi-stage flash distillation plants produce 85% of all desalinated water in the world) or solar distillation.
• D) Food.
-Supplied from shore or surface (cooked meals sent down in transfer pots).
-Stored on board either canned dried or refrigerated.
-Hunted or raised (Mariculture – open ocean fish or shellfish farming).
-Cooking by microwave, hot plate or electric range .
