Figure 4: Magnetic susceptibility records of a north-south profile from the Laptev-Sea continental margin
including the records from cores PS2471, PS2474, and PS2476 (Fiitterer, 1994; Niirnberg et a!., 1995). In
addition the AMS 14C-dated magnetic susceptibility record of nearby Core PS2778 (Rachor, 1997; Weiel, 1997)
is shown (for location of the core see Figure 3). The AMS 14C dates determined on marine bivalves, are corrected
by a reservoir effect of 550 years.
