Calcareous Nannofossils From The Southeast Greenland Margin: Biostratigraphy And Paleoceanography
The distribution of calcareous nannofossils in Leg 152 sites on the southeast Greenland Margin is documented. The nannofossil biostratigraphy established here provides valuable age information for the recovered sediments and a number of important events, including the initiation of marine sedimentat...
