Figure 1. Vertical profiles of TOC, C/N (TOC/TN weight ratio), total sulfur, and carbon isotopic composition of TOC in the upper part of Hole 1017E. TOC = total organic carbon, YD = Younger Dryas, IS 1 = interstadial Event 1, IS 2 = interstadial Event 2, cmbsf = centimeters below seafloor. Arrows indicate a sandy layer. Shaded areas depict IS 1 and IS 2?.
