High-resolution last deglaciation record from the Congo fan reveals significance of mangrove pollen and biomarkers as indicators of shelf transgression


The AA. report here data on the occurrence and high abundance of Rhizophora pollen, in association with taraxerol, from a high-resolution Congo fan core covering the last deglaciation. An age model based on C 14 dates enables the temporal changes in the percentage frequencies and flux of mangrove pollen, and in biomarkers, to be compared with pre-existing independent data on relative sea-level change in this region and with the hypismetric curve for the Congo margin. This approach therefore provides a basis with which to test the hypothesis that high quantities of mangrove pollen can be used as an indicator of transgression across tropical and sub-tropical continental shelves
