| บทคัดย่อ/คำอธิบาย | : | Calcite dissolution in marine sediments is known to be driven by the degree of saturation state with respect to calcium carbonate, of overlying bottom waters. Three paleocarbonateion proxies, planktonic foraminifer size index, shell weight and calcite crystallinity applied to a set of core top samples reveal that calcite dissolution commences from 2250m onwards and intensifies at around 3900m water depth in the Western Tropical Indian Ocean 1. It was proposed earlier that carbonate dissolution can be caused due to acidification of pore water 2. It is shown that shell weights of the foraminifera species Pulleniatina obliquiloculata indicate that this intense dissolution observed at 3900m was caused due to undersaturation of CO3= in the bottom waters in the Indian Ocean |
