Abstract
A very challenging quantitative biochronological problem integrating comprehensive diatom biostratigraphy, magnetostratigraphy, and tephrostratigraphy from 32 Neogene sections around the Southern Ocean and Antarctic continental margin has been recently studied by Cody et al. (Palaeogeogr Palaeoclimatol Palaeoecol 260:92–121, 2008). A new method, known as Constrained Optimization (Conop), which can be viewed as a multidimensional version of graphic correlation, is applied to that complex database. In this chapter we will review some discussions of a paper by Galster et al. (Palaeogeogr Palaeoclimatol Palaeoecol 285:237–247, 2010) concerning Conop and focus our analysis on the large scale correlations based on Cody’s data and the implication of the diachronism of “datums” in the quantitative treatment of biostratigraphic data.
