Notes: Grain-size classification used the following criteria: sand (>63 µm), silt (4–63 µm), and clay (<4 µm). TIC = total inorganic carbon determined by coulometer, TC = total carbon determined by element analyzer, TOC = total organic carbon calculated by subtracting TIC from TC. Carbonate weight percent is calculated by multiplying TIC by 8.333. Horizontal dashed line separates sediments described as pelagic carbonates (above) from those described as hemipelagic mud (below).
