Buoyant Flakes slide

[rob...@rtulip.net]

Hi Sev

I have uploaded your graphic at https://planetaryrestoration.net/f/buoyant-flake-ocean-fertilization

It includes a link to your document on Clive’s site - https://climategamechangers.org/wp-content/uploads/Rationale-for-Buoyant-Flake-Ocean-Fertilisation.pdf

It is a mystery to me why fertilization was the basis of the Green Revolution but there are such blockages to applying these concepts at sea in view of collapsing fisheries and the climate benefits.

Thanks & Regards, Robert

Hi colleagues,

 

Attached is my amateur attempt to describe the Buoyant Flakes concept in a single, Powerpoint slide. A good graphic artist would do much better. However, perhaps it might be good enough to go on the PRAG website and/or elsewhere, until we can arrange a suite of them using a standardised format for wider scientific, business, and public participation.

Comments, please.

Hi Sev,

The slide is good - nicely designed, but I think it would be even easier to read and understand if you put the section about the flakes themselves and the slow-release nutrients they provide, near the top left if the slide, in place of the section on 'buoyant nutriated diazotrophs'. Then perhaps you could put the diazotroph section towards the top right (and take out the words 'buoyant' and / or 'nutriated' if not necessary to describe the diazotrophs with both those adjectives). 

Otherwise, nice clear slide! 

Have a good weekend,

Daniel

Thanks, Robert,

The graphic looks well there, though there is now an update to it which includes some useful extra elements, see

A difference to the Green Revolution might be that folk regarded the ocean as pristine, whilst we now know it is anything but, because of the pollutants we have been adding to it since. Furthermore, the ocean iron fertilisation experiments that were undertaken in the past twenty years typically used highly soluble chemicals that were evanescent in surface waters and generated undesirable boom-bust algal blooms, whilst the buoyant flakes would release their nutrients slowly over a year and would be released at the sunlit ocean surface where they would do the most good. The attached theoretical analysis shows the indicative level of improvement.

I am now working on the more difficult compression of the Seatomiser/MCB/greening concept, its engineering design and likely effects into a similar single slide. To complete this I will need to depend on some CCRC capabilities that I lack, particularly as regards calculation of the sprayed seawater flow rate for selected modal droplet sizes, dispersal elevations, the power required, and just how much additional cooling, evaporation and downwind precipitation this would cause. 

Part of the difficulty is that I keep on thinking of further improvements. For instance, I now suggest separating the spray units from each powering wind turbine. As well as not complicating wind turbine manufacture and allowing several spray units to be linked to wind turbines of many sizes, this would also allow Seatomiser units to utilise power from the large number of existing offshore wind farms, thereby greatly speeding up deployment. 

Best wishes,

Sev

Sev, I find this very helpful as I am beginning to understand these many technologies.

One more minor suggestion:

"DMS emitted from phytoplankton" might read more easily than "Emitted DMS..."

My 2 cents for what it's worth.

Many thanks,

Manna

Hi Robert,

Here is a long (Williamson et al) and a short (Tollefson) answer to your question regarding blockage of ocean iron fertilisation. But there is hope, a revival is in sight.

regards to all,

Victor

Hi All

 

The attached file by Yoon is an excellent review of lots of iron experiments. Because of the high cost of running biochemistry labs in ships they did all the observations in a very short time.  I think that they were really measuring the skill of people keeping track of which bit of sea they were treating and Victor was by far the best at this very difficult task.

 

I would have preferred a somewhat lower dose over a much wider area over a period of several years with results measured by satellites in lots of different biological conditions, mainly where local people would be glad of the chance of more fish.  It would be hard to object to the increase in salmon catch in the years following Russ George’s effort, see

 

https://russgeorge.net/2020/10/26/a-picture-tells-a-thousand-words-bring-back-the-fish/

 

A possible way that long term iron treatment could be done is described in the second attachment. Apologies to people who have already seen it. Would it be illegal to be a bit careless with your corrosion protection?

 

Stephen
