Mayotte coral reveals hydrological changes in the western Indian Ocean between 1881 and 1994
Geophysical Research Letters

We reconstruct the hydrologic history of the tropical
western Indian Ocean by calculating the d18Oseawater from
coupled coral Sr/Ca and d18O measurements in a massive
Porites coral from Mayotte (Comoros) between 1881 and
1994. We found that the precipitation-evaporation balance
varies naturally on time scales of 5-6 years and 18-25 years.
High (low) SSTs are associated with positive (negative)
d18Oseawater implying that atmospheric variability is linked
with remote climate modes in the Indian Ocean and the
tropical/extratropical Pacific Ocean. Warm El Nino-Southern
Oscillation events are associated with a negative freshwater
balance at Mayotte. This case study demonstrates that a
much denser network of d18Oseawater reconstructions is
crucial for understanding the spatial patterns of hydrological
conditions.
STUDY NOTES: Coupled Sr/Ca and d18O measurements from a coral at Mayotte (Comoros)
used as a proxy for d18Oseawater and hydrological variability (P-E)
in the western tropical Indian Ocean.
