Ba incorporation in benthic foraminifera

Barium (Ba) incorporated in the calcite of many foraminiferal species is proportional to the concentration of Ba in seawater. Since the open ocean concentration of Ba closely follows seawater alkalinity, foraminiferal Ba Ca can be used to reconstruct the latter. Alternatively, Ba Ca from foraminifer...
