There seems to be some room for large scale mariculture in this IMO work, 
as well as, further need for clarification(s).


*"Ocean fertilization does not include conventional aquaculture, or 
mariculture, or the creation of artificial reefs.”.* This distinction does 
possibly leave open the door for large scale 
*OMEGA*<http://blog.marinexplore.com/nasa-omega-project-the-ocean-as-a-platform-for-biofuel/>
 projects 
which utilize nutricline <http://www.pnas.org/content/105/51/20344.short>water 
for the main nutrient input for algae cultivation. Also, the algae 
would use the dissolved CO2 within the nutricline water and thus "lowers 
the partial pressure of carbon dioxide (pCO2) in the upper ocean and 
facilitates the diffusive drawdown of atmospheric CO2." (see The role of 
nutricline depth in regulating the ocean carbon 
cycle<http://www.pnas.org/content/105/51/20344.short>
).


The DIC component (An Open Ocean Trial of Controlled Upwelling Using Wave 
Pump 
Technology<http://hahana.soest.hawaii.edu/lab/dkarl/2010JAtmosOceanTech27-385-396.pdf>
 see 
figure 2) of the nutricline water is readily used by the microalgae. The 
addition of Olivine (please see Geoengineering impact of open ocean 
dissolution of olivine on atmospheric CO2, surface ocean pH and marine 
biology <http://iopscience.iop.org/1748-9326/8/1/014009/article> and the 
works by Dr. 
Schuiling<http://www.innovationconcepts.eu/res/literatuurSchuiling/encyclopediaweatheringapproaches.pdf>)
 
to the OMEGA cultivation photobioreactors would help insure proper mineral 
content for robust microalgae cultivation, pH adjustment and enhance the 
overall “biological pump” effect of the the OMEGA operation.


The primary contention, most likely, would be the commercial nature of this 
'mariculture' approach to oceanic based GE. The commercialization of GE, in 
any form, can safely be predicted to create its own high level debate. We 
have to begin, however, to ask how should *any* GE project be funded? The 
OMEGA method does provide significant profit potential while addressing 
food/fuel/fertilizer/fresh water (etc.) needs. Although the profit 
potential is present and is needed to propagate/maintain such large 
installations, the OMEGA concept seems to offer the greatest good for the 
greatest number through large scale mariculture output while addressing 
ocean acidification, surface cooling within temperature critical waters 
(i.e. ENSO and/or Eastern Equatorial Atlantic), and atmospheric CDR.



It is the global demand and conventional means of producing 
food/fuel/fertilizer etc. which seems to do the most damage to our 
planetary environment. Any GE concept which can substantially address these 
important and highly problematic needs, would seem to be worth 
supporting...at all levels. Large scale mariculture can address both short 
term and long term GE needs and address our escalating demands for food, 
biofuel, organic fertilizer, fresh water and polymers.




It would be useful to get clarification from the LC/LP on their view of 
large scale OMEGA type projects on the specific point of such projects 
being "*conventional aquaculture, or mariculture",* or not.
