Lighting the Night to Enhance the Diel Migration

[Michael Hayes]

Lighting up the marine twilight zone to increase the marine biological pump space has been briefly discussed as an mCDR method. This new paper proposes lighting up the night sky to trigger an increase in microbial and higher trophs migration rates/time.

However, it is known that sea turtles can be confused by night lights.

If electric lights are used, Diatom production can be increased substantially.

They require very little light, the least among all types of phytoplankton and they grow better in cool water, so they will grow in the night.

Not clear why feeding at the surface and respiring/defecating at depth is a bad thing wrt atmospheric CO2. Doesn’t this promote C export away from the atmosphere? On the other hand, it does reduce photic zone nutrient cycling and hence primary production. Separate bio C flux/storage from (essential) nutrient recycling and you might have something?

This idea has dangerous side effects.

 

Most vertical migrators come up when the moon is dark, and stop near full moon. Surface illumination will suppress vertical migration, and hence carbon pumping.

 

A major consequence of the collapse of fisheries is a switch by most of the world’s largest fishing countries, China, Indonesia, Philippines, and Thailand, to catching squid using powerful lights directed downward at night, which attracts squid, but may mess up everything else. This fishing with lights is mainly done when the moon is dark, doesn’t work in full moon. To my knowledge there are no studies of the ecological effects but they must be significant.

 

Light from land has been shown by Israeli researchers to mess up coral reproduction which is cued to lunar rhythms, makes them release sperm and eggs out of synch causing reproductive failure, and blue light reduces coral skeleton growth.

Not clear why feeding at the surface and respiring/defecating at depth is a bad thing wrt atmospheric CO2. 

Doesn’t this promote C export away from the atmosphere?

Yes. 

In deep waters the CO2 respired / OC defecated at depth will remain in the water for a long time, decades. 

Just like the ~2.5 GtC/yr of atmospheric CO2 that is being absorbed into the oceans.

The only issue is that most of the increase in primary production will take place in relatively shallow waters, 

since this is where more nutrients are available. 

Consequently most of the respiration & defecation will take place in shallow waters and the CO2 will escape into the atmosphere.

On the other hand, it does reduce photic zone nutrient cycling and hence primary production.

If Diatom Algae are grown the primary production will increase, due to efficient recycling of the nutrients.

If other types of algae grow, nutrient recycling will be less efficient.

Separate bio C flux/storage from (essential) nutrient recycling and you might have something?

Nature does this very efficiently.

We just need to enhance all the natural processes that contribute to C flux and storage and nutrient recycling.

These processes are Diatom production - Zooplankton / Fish / Coral / Shellfish / Whale, etc., production.

Animal biomass in the oceans should be increased to the maximum extent possible. 

Animal biomass in oceans is estimated to be less than 10 GtC.

Plant biomass on land is estimated to be up to 650 GtC.

The gap must be closed.

Every problem has a solution. 

It's just a question of understanding the details and getting the details right.

1. Lights can be dim lights, not bright lights.

2. Only a small area can be lit, say 10% of the total area in each zone that it taken up for lighting, i.e., if lighting is sought to be used in a 100 sq km area, lights should be installed in ONLY 10 sq km area out of the 100 sq km area.

3. Lights can be switched on only for 14 or 15 days in a month, 1 week before and after Full Moon day.

4. Lights can be used only for a few months each year, sensitive periods can be avoided, such as spawning season, etc. 

Any new solution must be taken up cautiously.

Unfortunately, no research is being done on ALL possible solutions.

Clarification:

most of the increase in primary production will take place in relatively shallow waters, since this is where more nutrients are available

 

is incorrect, photosynthesis is light limited with depth, so production is greatest at the surface, where nutrients are least available due to consumption.

[Bhaskar M V]

Dr Goreau 

What I said and what you are saying mean the same thing.

photosynthesis is light limited with depth, 

Exactly, that's why photosynthesis is higher in shallow waters. 

so production is greatest at the surface,

Shallow waters = Surface.

 where nutrients are least available due to consumption.

Nutrients availability means input of nutrients available for consumption,  I.e., before consumption NOT inventory AFTER consumption. 

Regards 

Bhaskar 

[Tom Goreau]

Not quite, light controls nutrient UPTAKE, not availability or concentration, which depend on internal nutrient recycling and external nutrient inputs from upwelling, or water or wind transport from land-based sources.

[Bhaskar M V]

Nutrient availability = Total nutrients available for consumption = internal nutrient recycling  + external nutrient inputs from upwelling, or water or wind transport from land-based sources.

My terminology and yours are different, we mean the same thing. 

Regards 

Bhaskar 

[Tom Goreau]

There’s a tradeoff between nutrient and light limitation (most of all around Antarctica). Phytoplankton needing high light levels, like diatoms, coccoliths, and dinoflagellates, are adapted to live in nutrient depleted surface waters and are nutrient limited, but the nannoplankton like Prochlorococcus and Synechococcus have pigments adapted to grow deeper, at lower light levels and higher nutrient concentrations.

[Amal Bhattarai]

It is not necessary for primary production to pass through the gut of consumers to cause sinking/sequestration of carbon.  

Light application below the feeding depth will also grow phytoplankton, and turning the light off will kill and sink said phytoplankton whether or not it is consumed. Depth location avoids interference with the natural cycle of production-consumption which is now above the light application zone. The effect may work better in gyres with sparse biota and DVM.

Since the lifetime of phytoplankton is in the order of a week (including nighttime), 3-4 days of continuous (but optimized by pulsing) red light should deplete available carbon and sequester it (by natural death), whereas a shorter light application for 1-2 days would kill/sink youthful phyto.   The light application zone can then be relocated.  

Immediate impacts on sea life may occur, but only for a few days.

[Bhaskar M V]

Amal

True, it is not necessary for primary production to pass through the gut of consumers to cause sinking/sequestration of carbon. 

In fact more Carbon would be sequestered if the Phytoplankton falls to the ocean bed directly without being consumed.

However the smaller Zooplankton are likely to grow wherever phytoplankton are available, so avoiding consumption would be very difficult.

'Feeding depth' is based on the current depth up to which primary production takes place, this is limited by light availability.
If light were to be made available at greater depth, the production depth would increase and so would the feeding depth.

[Bhaskar M V]

Dr Goreau

I would like to rephrase what you wrote.

Phytoplankton needing high light levels, like diatoms, coccoliths, and dinoflagellates, are adapted to live in nutrient depleted surface waters and are nutrient limited, 

In surface / shallow waters, diatoms, coccoliths, and dinoflagellates grow and consume all the nutrients. Except in a few HNLC zones, where the nutrients are not fully consumed, due to lack of Iron and other micro-nutrients. 

but the nannoplankton like Prochlorococcus and Synechococcus have pigments adapted to grow deeper, at lower light levels and higher nutrient concentrations.

Prochlorococcus and Synechococcus require less light than diatoms, coccoliths, and dinoflagellates and they grow at greater depths where light is limited. 

However, their production is not adequate to consume all the available nutrients.

Therefore providing light at these depths will enable growing more Prochlorococcus and Synechococcus and perhaps also Diatoms. 

Diatoms perhaps require more light than Prochlorococcus and Synechococcus, but less than coccoliths and dinoflagellates or perhaps Iron and other micro-nutrients are not available at these depths, so these too need to be provided, in addition to light.

There is a risk that such light will suppress vertical migration of some zooplankton, and their carbon defecation pump to the deep.

[Tom Goreau]

They are fussy, they prefer to dump carbon in the dark!

[Amal Bhattarai]

Dr Goreau: “defecation pump” , if you will, is inefficient - few percent of consumed carbon makes it to the deep ocean. 

Light Application for a few days around the full moon could eliminate this issue altogether because zooplankton are not migrating. 

Light Application under arctic winter ice also eliminates interference with this natural cycle. 

Lastly, light application is local, tens of sq km at a time, and next application can moved many kilometers away.  

Looking forward to more comments on this topic. 

-Amal

[Tom Goreau]

Interesting ideas, and worth testing, but needs measurements.

 

The squid fleets must be having huge effect in South East Asia. At full moon the ocean is brightly up all across the horizon, hundreds of boats can be visible at a time from single locations. Need measurements there too!

Dr Goreau

Lights would be placed at a greater depth than Sunlight and Moonlight penetrate, 

so this would be waters in which there is nil, or very little, photosynthesis at present. say more than 100 meters deep up to 200 meters.

I understand that at present Zooplankton come to the surface waters, say top 100 meters, feed and then dive and defecate below the photic zone.

If lights are used the Zooplankton would be able to feed in the 200 to 100 meter artificially lit zone and then dive deeper than 200 meters.

So one basic science question would be - 

Will a change in depth of the photic zone from just 100 meters to 200 meters adversely change the zooplankton feeding and defecation behaviour. 

A few experiments will prove what would happen.

At present bright lights are being used to KILL squid.

We should use dim lights to GROW phytoplankton.

The more anoxic the water becomes, the more toxic the water Hg becomes. Keeping the light triggered biotic 'crop' from becoming food might need addressing.

A large floating funnel, or other means of shielding the crop from predation, can use Biorock and other building materials. The origional paper on Biorock has detailed plans for deep reaching infrastructure.

Open water deep light mCDR has the attraction of engineering simplicity, energy efficiency, yet the MRV values will likely be soft, much like OIF. Rapidely transitioning from open water deep light use, simplistic rather cheap field trials are needed, to using large scale marine infrastructures can likely firm up the MRV value as predation can better be controlled for. From a water health Hg perspective, predation likely needs control.

Biorock can be done anywhere in the ocean, the problem is to provide power. Wolf  Hilbertz did short term experiments using submersible batteries thousands of meters down in the Cayman Trench. With fuel cells it should be easy to build bottom reefs as moorings for floating structures, and to power lights on them.

[Tom Goreau]

The issue of lighting the deep sea is very complex because all marine life has evolved circadian rhythms of feeding, migration, defecation, sex, etc. cued to moonlight, and these will be unpredictably affected by un-natural light sources.

 

Some plankton and fishes are greatly attracted to light, which is why it is such an effective fishing tool for squid, but others totally avoid it.

 

Phosphorescence in the deep sea is constant, light is used to signal, communicate, and attract food, or confuse predators. William Beebe, the first to describe this from immersion thousands  of meters in the bathysphere saw vast numbers of light flashes, most of which could never be identified even when the turned on the spotlight. Most was too faint to photograph. Most marine organisms stopped emitting light immediately, and could never be seen, some were invisible in light, but some flooded the water with light emitting pigments to blind predators. Even today, when people have sophisticated submarines, cameras, and probes, most of what flashes light in the dark of the deep sea is completely unknown.

 

Conclusion: Putting light sources in the deep ocean will have complicated and unpredictable consequences, that would need to be experimentally discovered.

Outstanding Tom!

Conclusion:  As humans we know less than we think we do and we need to work within the sphere of the natural world instead of trying to recreate something we have neither the power nor the intellect to accomplish.  
Consider the American Bison story and the cataclysmic effect their destruction caused.

I’m just saying that careful testing is needed before anyone really knows the impacts.

 

It could well be useful in certain places, depends on how local organisms respond.

 

Phytoplankton under ice should respond strongly all year round because they are light limited and probably not nutrient limited.

Subject: Re: [CDR] Lighting the Night to Enhance the Diel Migration

Dr Goreau- my motivation while coming up with the deep light idea was to cause the least possible harm to biota [and least impact to human activities] while accessing a limitless supply/storage potential for atmospheric CO2.  It seems to me that all massively scalable CDR methods show some harm to nature, except growing a very large number of trees, which is a nonstarter because it affects human land use.

 

Are there any large ocean locations where there is minimal resident biota? [Transient biota will not be eliminated by a few days of extra light.]  My first guess for lowest impact by artificial light is the surface waters immediately under arctic/antarctic ice in the wintertime.

 

Outstanding Tom!

A large survey of the Twilight Zone was just completed by WHOI. At the start of the expedition, I did ask them to investigate lighting up the dysphotic biota for a few days, yet they had tight plans beyond that.

https://twilightzone.whoi.edu/

Open water use of lights will obviously carry wide area, highly complex, concerns. Using bioreactors at the dysphotic level, with all generated light used inside the hulls, is likely easier to get approved than open water light use, and using reactors will likely show much better mCDR MVR values due to processing controls.

[Michael Hayes]

Marine engineering standards for electrical generation and air compression for strictly offshore use is maturing, and using such technology can support large scale offshore cultivation operations. Photobioreactors can double as heave anchors opening up highseas water, energy, and nutrient nexus independence from terrestrial WENN resources. 

https://youtu.be/M4nMUmxmCpY?si=T8aBLIwLtepvTFWx

Getting the price of this tech package down to a <$5M per unit cost to a new mCDR 'farmer' is a reasonable startup challenge. 

[Bhaskar M V]

How much light is required for Photosynthesis?

We first need to discuss this.

Then we can discuss how artificial lighting is required to increase Ocean Photosynthesis to grow a few billion tons more Phytoplankton.

Otherwise, we are just shooting in the dark [ pun intended :) ].

My view is that at present the amount of light required for Photosynthesis is being overestimated.

I have not seen a single paper on the subject, by someone who has experimented with low light to grow phytoplankton.

Not one comparative experiment has been done between various types of phytoplankton, 

to understand which requires the least amount of light. 

This kind of experiment will throw more light on the subject :) .

Not one country has set up a Climate Change Solution Research Institution, 

to coordinate and manage research on ALL possible solutions to climate change.

My initial calculations indicate 100mW pulsed red light will condense the 28 grams per cubic meter carbon into plankton over a 72 hour period.  Billions of tons seem achievable by spreading light over a large area. By December,  I hope to have results of ECCO-Darwin model runs (modelers ready to go, funding not ready yet)

[Bhaskar M V]

Amal 

Great news. Thanks for taking up this experiment.

There are many types of phytoplankton.

The experiment needs to be done with different types and species to understand which require more and which require less light.

[Tom Goreau]

The photosynthesis versus light curve is the most fundamental characteristic of phytoplankton, and is very well documented in the phycology literature. There are significant differences between groups depending on their pigments, physiology, and biochemistry, so some specialize in high light environments, some in low light, some in between. But all need some light, and the phosphorescence in the deep sea is insufficient.
