Short summary
Recent concern about the repercussions of rising atmospheric CO2 as a key heat-trapping agent have prompted ocean experts to discuss ocean alkalinity enhancement (OAE) as a CO2 removal approach but also as a potential way to mitigate ocean acidification. This chapter provides an overview of best practice in OAE laboratory experimentation by identifying key criteria to achieve high-quality results and providing recommendations to contrast results with other laboratories.
