Distinct cyclicity in lithology and microfaunal distribution in sediment cores from the Mendeleev Ridge in the western Arctic Ocean (water depths ca. 1.5 km) reflects contrasting glacial/interglacial sedimentary patterns. We conclude that during major glaciations extremely thick pack ice or ice shelves covered the western Arctic Ocean and its circulation was restricted in comparison with interg...

David Bowen perhaps stands in the middle, with an interactive approach to terrestrial and oceanic stratigraphies. He started uncontroversially by affirming the importance of defining chronostratigraphy from local terrestrial sequences and correlating outwards only from that starting point. However, he also stated a firm belief in the importance of broader correlations with the ocean sequence, a...
