Opening of Drake Passage and Its Impact on Cenozoic Ocean Circulation

| Summary: | Abstract In 1977, an article concerning the “Cenozoic evolution of Antarctic glaciation, the Circum-Antarctic Ocean and their impact on global paleoceanography” was published by Kennett. He correctly deduced many of the tectonic causes of the Cenozoic evolution of both Antarctic glaciation and global paleoceanography. Even without an absolute plate tectonic framework and direct knowledge of opening of Drake Passage between South America and Antarctica (Fig. 10.1), the conclusions in his paper are still valid. In the interim, compilation of a global database of marine magnetic anomalies and fracture zone lineations based on satellite derived gravity has enabled us to produce an absolute plate tectonic framework for the Cenozoic (Muller et al., 1993). |
