Short summary

Coccolithophores are global calcifiers, potentially impacted by ocean acidity. Data from the Southern Ocean is scarce, though latitudinal gradients of acidity exist. We made measurements of calcification, species composition and physiochemical environment between America and the Antarctic Peninsula. Calcification and cell calcite declined to the south, though rates of coccolith production did not. Declining temperature and irradiance were more important in driving latitudinal changes than pH.
