Columns are sample interval reference names and Marine Isotope Stage (MIS) names, core ID, sample depth (cm), sample age (ky), mean individual foraminifera temperature (°C), median absolute deviation (MAD), mean of the 94^th–98^th quantile normalized temperature (Q94-98T), number of foraminifera analyzed (N), and change in El Niño amplitude. For glacial periods MIS 6 and MIS 8, decimal notation refers to the indexed number of sampled intervals from that stage. El Niño amplitude change was determined by Q–Q analysis. Plus-signs indicate increased El Niño amplitude, minus signs reduced El Niño amplitude. The asterisk denotes an interval that displays significantly reduced El Niño amplitude at the 90% confidence level but may be a false positive result.
