Short summary
Short summary
The Bay of Bengal is a unique region influenced by the Asian monsoon. We present a record of past ocean productivity and carbonate flux based on the fossil remains of calcifying algae over the last 279 000 years from a core in the northern Bay of Bengal. We used AI microscopy to count and measure plankton fossils and identify species. Results show that coccolith export, including of the species Florisphaera profunda, is highest when the monsoon is weak and the water column is more mixed.

Short summary
We test a new method to reconstruct past atmospheric CO2 levels based on the geochemistry of pelagic algal biominerals (coccoliths), which recent culture and numerical experiments have related to ambient CO2 concentrations. By comparing the isotopic composition of fossil coccoliths to the inferred surface ocean CO2 level at the time they calcified, we outline a transfer function and argue that coccolith vital effects can be used to reconstruct geological pCO2 beyond the ice core record.

Short summary
Short summary
Oxygen minimum zones are oceanic regions almost devoid of dissolved oxygen and are currently expanding due to global warming. Investigation of their past behaviour will allow better understanding of these areas and better prediction of their future evolution. A new method to estimate past [O2] was developed based on morphometric measurements of benthic foraminifera. This method and two other approaches based on foraminifera assemblages and porosity were calibrated using 45 core tops worldwide.

Short summary
We provide high-resolution Cd / Ca records of benthic foraminifera on two cores from the northern Indian Ocean since the last deglaciation. We reconstructed intermediate Cdw records based on Cd / Ca. Combined with benthic foraminiferal assemblages, we show that intermediate Cdw during the last deglaciation was mainly influenced by the ventilation of intermediate–bottom water masses. Thereafter during the Holocene surface productivity is the main forcing factor related to monsoon precipitation.
