Figure F3. Physical and chemical properties of Site 1169. A. Relative sediment disturbance from 0 (no disturbance) to 4 (soupy or vertically deformed). B. Colorimetric coordinate b* by spectrophotometry (blue to negative and yellow to positive values). C. Calcium carbonate content in weight percent (see "Organic Geochemistry"). D. Relative abundance of siliceous and calcareous microfossils as identified in smear slides, standardized against calcium carbonate content. Nonbiogenic components, such as clays and in situ minerals, are generally in low abundance (~10%) and are not considered in this diagram. TD = total depth.
