๐ŸŒŠ For the first time researchers used โ€œlab and wind-wave tank experiments to prove the concept of using Mg(OH)2ย for the #OceanAlkalinityEnhancement and #CarbonDioxideRemoval approach (OAE-CDR).โ€ย 

๐Ÿงต1/7 Image
๐ŸŒŠ Experiment results showed โ€œup to 370โ€ฏฮผmolโ€ฏkgโˆ’1 seawater total alkalinity (TA) increase without precipitation, stable enhanced TA, and OAE-CDR efficiency (ฮ”DIC/ฮ”TA) consistent with theoretical calculation.โ€

๐ŸŒŠ Based on the experimental results, scientists involved in this study calculated โ€œthe global Mg(OH)2 OAE-CDR efficiency and #CO2Sink from this approach.โ€

Recent analysis published in @naturesustainab โ€œuse #biogeochemical simulations to show that restoration of the marine ecosystems can lead to permanent #CO2Removal by driving #OceanAlkalinityEnhancement & atmosphere-to-ocean #CO2Fluxes.โ€

Key findings in a๐Ÿงตโฌ‡๏ธ

Findings of this study suggest that โ€œrestoring mangroves, which are common in tropical shallow marine settings, will lead to notable local #OceanAlkalinityEnhancement across a wide range of scenarios.โ€

โ€œThe process is seagrass & mangroves influence the organic & inorganic cycling of C in sediment, with strong impacts on diffusive #alkalinity fluxes. In carbonate-rich sediment, seagrass & mangroves foster carbonate dissolution, resulting in increased alkalinity production...

&
๐ŸŒŠ#OceanAlkalinityEnhancement."

Various conclusions were drawn in the review which are enlisted below:

1๏ธโƒฃ "The alkalinity of the ocean creates a massive increase in the oceanโ€™s capacity to #store #carbon, relative to a scenario without #OceanAlkalinity."

2๏ธโƒฃ "Ocean warming causes decreases in both #CO2 #solubility and the Revelle factor (B), which make the ocean less efficient at #absorbing CO2."

An analysis of published data exploring the effects of high pH on #phytoplankton growth rate & experimental assessment of pH dependence of viability & growth rate was used in a "lately published thesis" to assess potential impacts of #OceanAlkalinityEnhancement.
๐Ÿงต
1/4 ImageImage
๐Ÿ“‰ The results from this study suggest that there will be no significant impact on the viability or growth rates of Thalassiosira pseudonana or Pavlova lutheri with short-term (10-minute) exposure to elevated #pH.ย 
#OAE
2/4 ImageImageImage
However, when long-term (days) exposure occurs there is a significant decrease in growth rates with high pH. Short-term exposure is predicted to more closely mirror the natural systems in which #OAE will be implemented because of system flushing & replenishment of nutrients.ย
