Ocean-Based Carbon Removal (AirMiners Event Series)

Flowing from a strong undercurrent of interest, AirMiners is happy to announce an ocean carbon dioxide removal event! There’s been a wave of news in this space, suggesting that the tides are turning for further developing carbon removal in aquatic systems.

Our theme is "Pathways and Methods" at the headwaters of ocean CDR innovation, with eyes to a future downstream AirMiners event focused on entrepreneurship in this space.

Excellent summary of the issues by Brad Ack.

All in all, I think the default position should be to aggressively do direct air capture, with carbon-free energy (maybe just waste heat), and let the ocean gradually release its excess CO2 and equilibrate, over whatever time frame it's going to take. As we learn more, we may want to cautiously deviate somewhat in a more aggressive direction, if it looks safe. But the thing is, direct atmospheric air capture (DACC) this needs to be done *ASAP*. Consider this: The excess CO2 in the air is equivalent to something like 40 to 45 years of emissions at the present rate. We need to be taking the CO2 back down at some kind of comparable rate. Then, as I said, let the ocean respond to that drop, and we should be in pretty good shape (or about as good as can be expected). First, do no harm.

Risk assessment is interesting. What system could we possibly do more deadly than climate change?

question if you pump seawater from the deep ocean to the surface and heat it how much nitrogen, oxygen and carbon dioxide comes off and might that be a better gas mix than air for co2 capture... Gas - Chemical Symbol Percentage in Air Percentage in Sea Water
Nitrogen N 2- 78.08- 62.6
Oxygen O 2- 20.95- 34.3
Argon Ar- 0.934- 1.6
Carbon Dioxide CO 2- 0.033- 1.4

Sadly two of the speakers are against it in different ways. Totally rediculous that the host has to pretend that commercialization is a bad thing. David Koweek is informed and motivated. Wonder if carboncredits can be used to pay for a project
