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

โThe 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...

Various conclusions were drawn in the review which are enlisted below:
1๏ธโฃ "The alkalinity of the ocean creates a massive increase in the oceanโs capacity to #store #carbon, relative to a scenario without #OceanAlkalinity."

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.

๐ 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

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
