- An open-ocean artificial upwelled system, however, shows promise for both providing revenues and, possibly, positively impacting the environment. Properly managed, the high-nutrient deep waters can induce growth in the photic zone, on balance, although possibly with the need to add iron, uptaking carbon dioxide from the atmosphere. Much of the CO2 formed will sink to the bottom of the ocean, where much of it will remain trapped for a long, long period. The carbonate cycle slowly transforms the gas back into the atmosphere, but those bound in silicate compounds remain in place for many millennia (Berner and Lasaga, 1989).
Above is an OTEC facility on Kumejima, Okinawa, actually producing OTEC electricity today. To the right is the open cycle OTEC power plant built by the Pacific International Center for High Technology at NELHA, borrowed from the website of Ocean Thermal Development Corporation, one of the more progressive companies in this business.
- Two potential oceanic mechanisms to help mitigate global warming are (Phillips, et al, 1991):
- enhanced carbon dioxide uptake via nutrient subsidy to marine algae and subsequent deposition in marine sediments and
- enhanced dimethyl sulfide production via marine algae to increase cloud formation and albedo.
|The paper Stan Dunn, other colleagues and I wrote (incidentally, elimination of hurricane formation was another enhancive potential, which was detailed in that publication, but left out in this discussion today) went on to conclude that:|
|serve as an incubator for new marine industries,|
|develop the package of integrated products, and|
|test the upwelling concept.|
There are four tropical disturbances headed for Hawaii:
None should approach hurricane strength. Which leads to the question of the day. What was unusual about the hurricane season in the Atlantic a century ago, 1914? ZERO HURRICANES.
