Notes: [1] = equivalent revised meters composite depth interval in Site 1020 and age model established by correlating Site 1018 with Site 1020. [2] = dry bulk density estimated by linear correlation of Leg 167 index properties data: dry = (1.563 wet - 1.560). [3] = mass accumulation rate (MAR), or burial flux.
