Figure 28. Conceptual diagrams showing the long-term shift from temperate to cold conditions across the continental margin at Prydz Bay, from times of wet-based glaciers with fluvial systems to those of dry-based(?) ice sheets in maximum glacial-interglacial conditions. During the transition to cold times, short-term seaward-landward shifts in glaciers (double arrow) may explain the cyclic gray/green sedimentation patterns with Milankovitch periodicities (i.e., Site 1165; early Miocene and younger times).
