| This chapter gives an overview of the environmental changes to the European shelf and its marginal seas during the Late Pleistocene to the Middle Holocene. It first explains the regional tectonics of Europe. The age of the consolidation of the basement together with the plate tectonic setting serves as the main parameters determining coastal formation. Next, the chapter reviews the fluctuation of glacial and interglacial stadia as an effect of orbital parameters of the Earth around the Sun. In addition, it examines eustatic change during the Last Glacial Cycle (LGC). The chapter also describes the development of the Baltic Sea, the North Sea and the Atlantic shelf, based on numerical sea-level scenarios constrained by observational data. Finally, it... |

| Based on 17 AMS(14)C age data, we reconstructed high-resolution records of sea surface primary productivity (PP) in the southern Okinawa Trough (MD05-2908) over the last 6.8 ka BP using the calcareous nannofossil carbon isotope and the relative percentage contents of Florisphaera profunda indexes. The underlying mechanism controlling the sea surface PP was then discussed. The sea surface PP, indicated by the coccolith delta C-13 and %Fp conversional equations, decreased with some fluctuations since 6.8 ka BP. This decrease may be connected to the decreased terrigenous input resulting from the reduced East Asian Summer Monsoon (EASM) precipitation. Both the periods of 4-2 ka BP (PME) and 6.8-4.8 ka BP were characterized by relatively higher PP. The former... |
