On the validity of foraminifera-based ENSO reconstructions

Metcalfe, Brett; Lougheed, Bryan C.; Waelbroeck, Claire; Roche, Didier M.

Video of model run. Calculated oxygen isotope values of three species of planktonic foraminifera (\( \delta^{18}O_c\)) using the Foraminifera as modeled entities (FAME) module and Ocean Reanalysis data temperature and salinity data. Upper panel represents the Oceanic Nino Index (ONI) used to determine the ocean state for each monthly time step, lower panels the \( \delta^{18}O_c\) for each individual species of planktonic foraminifera (G. ruber; G. sacculifer and N. dutertrei).
