Description:
We investigated benthic foraminifera in cores GPC03 and GPC04 in the northeast tropical Indian Ocean (TIO) over the past ~450 ka to evaluate the ballasting effect of particulate organic matter (POM) and the long-term zonal change during the mid-Brunhes dissolution interval (MBDI). Today, interannual climate and oceanographic variability in the TIO is governed by the Indian Ocean Dipole (IOD), which manifests as asymmetric zonal oceanographic change. Here we provide our sediment geochemical, stable oxygen and carbon isotope data and faunal data of benthic foraminifera in core GPC04.
