The distribution of deep-sea benthic foraminifera in core tops from the eastern Indian Ocean

The second ordination-axis scores identify another taxon, Uvigerina proboscidea. The distribution of this species is mainly limited to low latitudes (north of 25°S), where carbon flux rate is high (> 3.5 g C m− 2 year− 1), due to higher primary productivity levels at the sea surface, and oxygen levels are low (< 3 ml/l) due to the organic matter oxidation and the presence of oxygen-depleted Indonesian Intermediate Water and North Indian Intermediate Water.
