An assessment of the Sr/Ca ratio in shallow water hermatypic corals as a proxy for sea surface temperature

Marshall, Jerry; McCulloch, Malcolm


The high precision measurement of the Sr/Ca ratio in corals has the potential for measuring past sea surface temperatures at very high accuracy. However, the veracity of the technique has been questioned on the basis that there is both a spatial and temporal variation in the Sr/Ca ratio of seawater, and that kinetic effects, such as the calcification rate, can affect the Sr/Ca ratio of corals, and produce inaccuracies of the order of 2-4 °C. In the present study, a number of cores of the...[Show more]
