Stable isotope geochemistry of corals from Costa Rica as proxy indicator of the EL Niño/southern Oscillation (ENSO)
Abstract
We analyzed the δ18O and δ13C time-series contained in coral skeletons collected from Isla del Caño, Costa Rica, that survived the 1982–1983 El Niño warming event. Coral δ18O give a record of thermal histories with a precision of ~0.5°C. For this locality, we have determined that the average Δδw effect in the coral skeletons is equivalent to 33% of the skeletal δ18O range. Therefore, if δw effects are not compensated for, the annual …
