🚨NEW STUDY🚨

🌊 For the first time researchers used “lab and wind-wave tank experiments to prove the concept of using Mg(OH)2 for the #OceanAlkalinityEnhancement and #CarbonDioxideRemoval approach (OAE-CDR).” 

🧵1/7

🌊 Experiment results showed “up to 370 μmol kg−1 seawater total alkalinity (TA) increase without precipitation, stable enhanced TA, and OAE-CDR efficiency (ΔDIC/ΔTA) consistent with theoretical calculation.”
2/7

🌊 Based on the experimental results, scientists involved in this study calculated “the global Mg(OH)2 OAE-CDR efficiency and #CO2Sink from this approach.”
3/7

🌊 Results suggested that, “the efficiency is in favor of lower initial DIC to titration alkalinity (TA) ratio, lower temperature, and higher atmospheric CO2, and therefore is the lowest at the equator (0.7–0.8) and increases with latitude (1.0–1.2 above 70 N/S).”

🌊 However, “factoring in the ocean's surface area, low latitude regions can #absorb more atmospheric CO2.”
5/7

🌊 Researchers' team “conservatively estimate that 44. 4 × 109 ton of CO2 (~ 3.3 times of current annual #CO2Sink in the ocean) could be removed from the atmosphere with 175 μmol kg−1 Mg(OH)2 (equivalent to 350 μmol kg−1 of TA) added to the top 10 m of the ocean.”
