| Abstract: | Analysis of surficial sediment samples collected during north-south transect in Indian Ocean indicate that south of latitude 50°S δ¹¹⁸O increases while δ¹³C declines. Signature of Polar Front at around latitude 50°S shows specific response of isotopic values of planktonic foraminifera Globigerina bulloides and is ascribable to general decrease in ambient temperature, resulting in continuous increase in δ¹⁸O values, while δ¹³C values decrease as result of reduced photosynthesis in high latitude regions owing to low light penetration. Results indicate potential of such data as proxy to assess movement of frontal systems in high southern latitudes. |
