1. The movement of seawater in a pattern of flow dependent on variations in temperature, which give rise to changes in salt content and hence in density is called as thermohaline circulation . figure below. 2.The δ13C values recorded in benthic foraminiferal calcareous tests reflect the δ13C values of the dissolved inorganic carbon (δ13C∑CO2) of ambient deep and bottom water masses and as such are widely used as a nutrient proxy to reconstruct deep ocean paleocirculation e.g Cibicides (δ13CCib), is one of the most widely used
