Calcareous dinoflagellates as indicators of orbitally driven climatic variation

Climate has been a strong focus of research in recent decades. Increasing awareness of today's climate has fuelled scientists to investigate past climates and attempt reconstructions using and incorporating results from the growing numbers of proxies that have become available.

Climatic precession has been shown to heavily affect the Mediterranean. However, the nature of the impact, with specific focus on the time of the onset of the Northern Hemisphere glaciations (2.5Ma), is still unclear. By using calcareous dinoflagellates from the Pliocene rhythmically-bedded Monte Singa section (Calabria, S Italy), we have tried to elaborate further on this issue.

The Singa section has provided a rich assemblage and broad diversity of excellently preserved calcareous dinoflagellates. By integrating new results from calcareous dinoflagellates with other proxies available from the same section, we provide new insights on photic zone conditions, such as nutrient availability, salinity and stratification, as well as secondary preservational effects.
