WebDec 19, 2024 · Ocean alkalinity enhancement (OAE) has the potential to mitigate ocean acidification (OA) and induce atmospheric carbon dioxide (CO 2) removal (CDR).We evaluate the CDR and OA mitigation impacts of a sustained point-source OAE of 1.67 × 10 10 mol total alkalinity (TA) yr −1 (equivalent to 667,950 metric tons NaOH yr −1) in Unimak Pass, … WebFeb 16, 2024 · pH Scale. Acidity is commonly measured using the pH scale. Pure water has a pH of about 7, which is considered neutral. A substance with a pH less than 7 is considered to be acidic, while a substance with a pH greater than 7 is considered to be basic or alkaline. The lower the pH, the more acidic the substance.
