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...

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
