By Anthony T. S. Ramsay

The built-in technique utilized within the research presents a reassessment of the stratigraphy formerly proven for the 18 holes which were re-examined. The authors set out the present figuring out of Southern Ocean biochronology and provides a synthesis of biostratigraphical and polarity information from earlier paintings. the quantity might be a precious reference for studying the palaeoceanography, climatic historical past and tectonic evolution of the Southern Ocean. It additionally presents a framework for relationship oceanography and sedimentary occasions which are used as proxies for analyzing the glacial heritage of Antarctica.

An age-depth graph for Hole 71-514 using the stratigraphical markers determined in this study is shown in Fig. 8. The section is interpreted to be continuous based on both palaeomagnetic and biostratigraphical control. 43 mbsf to the base of C3n. 51 mbsf. 96 mbsf. 79 mbsf. Unfortunately the absence of palaeomagnetic control points below this depth prevent an age assignment for this biostratigraphical event in this hole. 8 m below seafloor (mbsf) representing a recovery of 92% of the cored interval.
