Figure 3. Spliced records from Site 984 (Bjorn Drift). Discrete sample depths are plotted as solid symbols. A. Normalized whole-core magnetic susceptibility. Units are dimensionless magnetic susceptibility units per unit mass. B. Normalized whole-core natural gamma emission. Units are gamma counts per second per unit mass. C. GRAPE wet bulk density, corrected for source-sensor misalignment. Units are in grams per cubic centimeter.
