Figure F2. Plot of amorphous silica content of bulk sediment samples, Site C0011. Error bars indicate 95% confidence intervals. Horizontal dashed lines are lithologic unit and subunit boundaries from Expedition 333 Scientists (2012). The Subunit IA/IB boundary is defined at a change in the degree of volcanic ash alteration, with greater alteration below the boundary (Expedition 333 Scientists, 2012).
