We investigated ecological, physiological, and skeletal characteristics of the calcifying green alga Halimeda grown at CO2 seeps (pHtotal ~ 7.8) and compared them to those at control reefs with ambient CO2 conditions (pHtotal ~ 8.1). Six species of Halimeda were recorded at both the high CO2 and con...
