Whales and carbon transport

Fluxes would have been “at least three times higher” before industrial whaling.

A chart of the whaling grounds drawn in 1884 – Note the light shading is abandoned grounds i.e. those in memory at that time, it is likely that if records had gone back further that much more of the oceans would have been in the same light shading!

Bhaskar and list.
A member of this list once called for whale ranching, likely as a joke, yet setting up large integrated multi-trophic aquacultural sites that produce a wide variety of species simply for realease, so as to attract whales, is likely possible.
Using such artificial feeding grounds to help pull whales out of shipping lanes should also be seriously considered, both starvation and ship strikes are not helping. Engineered feeding grounds are used to pull deer and elk away from highways, and I have such a field next door. Doing the same for whales could likely earn a C credit, yet the MVR would likely be weak until lots of monitoring is in place.
Feeding whales would need to find some form of profit, preferably not whale meat, yet the needed tech is not a problem as it is currently being used on land, profitably, to feed humans.
How can profits be generated?

Dear Bhaskar, Bru, and whale lovers:
Thanks for the 1884 world map. It was a different world back then with a litany of species going extinct every year.
Whales and marine mammals have held a strong role in the marine ecosystem's dynamics including the carbon cycle. And therefore, it is refreshing to learn that one of HPAC's friends is leading an effort to rejuvenate the Whale Pump natural processing of co2 with the inauguration of Positive Polar.Positive Polar is the only cruise line enterprise that I know of who is dedicating their science and exploration to promote the welfare of whales and educate the Earth denizens to the carbon cycling role they play.Please take a look at www.positivepolar.com and share with your colleagues and friends. The leaders of this enterprise are pioneers for whale recovering and carbon capture and deserve your attention.Cheers to all, Tim

Dear Bhaskar:I include a degree in ecology in my academic and field experience. Of course, we are discussing the marine food chain with emphasis on the charismatic mega fauna and my favorite marine mammals. Pick your favorite plankton species and we will be in violent agreement. Just as India has chosen to follow the Green Revolution use of fertilizers, we are innovating for the greater good of the marine ecosystems with benefit of improving the carbon cycle.
The goal is careful proof of concept and attention to engineering scales. We are not broad brushing the ocean, but planting seas for broad adoption. If we convinced the IMO to remove sulfur from fuel (and this heated up the oceans a bit) we should not be shy about convincing the IMO to extend Whale Pump technology to all ocean going vessels. Obviously, there is much to do. Please stay tuned to guilt-free ocean tourism combined with science.
Please feel free to offering other methods.
Cheers, Tim

Hi Bhaskar
Disrupted and unbalanced ecosystems. Fish in the main are feeding at the first level on zooplankton that are the primary grazers of phytoplankton and if there are not enough of them, because they are being poisoned by the pollution of microplastics and forever chemicals that are most concentrated at the surface, then there is another break in the system.
So I think we should be looking at which algae supports zooplankton, and what we can do to improve their environment.
Best,

Zooplankton mainly eat phytoplankton, but many filter feeding invertebrates such as oysters, consume diatoms directly, especially in coastal waters. Both food chains need to be stimulated to restore productivity and biogeochemical health.

Membrane PBRs can use coastal treated sewage outfall streams to capture and utilize the nutrients for CDR work and agricultural:
An integrated algal membrane photobioreactor as a green-transition technology for the carbon capture and utilization
https://www.sciencedirect.com/science/article/abs/pii/S2213343722002172
The challange is not in the biology or processing technology but in the need for rapid lowest cost infrastructure scale-up.
The hull technology would benefit from being largely self-replicating at the basic materials level, and thick walled high density polyethylene hulls that generate bio-ethylene via internal operations should fit the definition of a largely self-replicating infrastructure at the basic materials level. Biorock is also a largely self-replicating building material, and biorock production likely can be a benefit to microalgal production outputs and used as external armor for HDPE mPBRs.
Building robust and long lasting, largely self-replicating, C negative mPBRs specifically for coastal outfall upgrades is likely achievable with current technologies, as would be using the sewage outfall feedstock to help feed the whales clean feed. We are already feeding them our crap, let's upgrade the menu mCDR style.
Below is an example of what large mPBR hulls would look like:

Bhaskar et al.,
Doing both is technically possible, yet reactors offer more environmental control and thus better crops growth and accounting and many more potential downstream coproducts.
Moreover, reactors likely provide maximum flexibility concerning crops that get grown. I don't understand how reactors would limit flexibility. Can you explain your view on that point?
