Description

The variability of seawater temperature through time is a critical measure of climate change, yet its reconstruction remains problematic in many regions. Mg/Ca and oxygen isotope (δ^18 Oc) measurements in foraminiferal carbonate shells can be combined to reconstruct seawater temperature and δ^18 O (δ^18 OSW). The latter is a measure of changes in local hydrology (e.g., precipitation/evaporation, freshwater inputs) and global ice volume. But diagenetic processes may affect foraminiferal Mg/Ca....[Show more]
