Terrestrial Palaeoecology and Global Change

2000). Such chronological correlations suggest common basic factors. Lacustrine sedimentation
is regulated by drainage runoff in turn controlled by sea level (the basis of
erosion) and precipitation driven by the precessional cycles. Similarly, marine cyclicity
results from sea-level-driven, as well as precipitation-driven fluctuations of terrestrial
runoff with impacts on density stratification, biotic productivity of surface waters and
oxygen concentrations down the water column (VII.1.1, VII.2.3, IX.3 and elsewhere).
