Dec 01, 1993 · There are errors associated with the sediment-accumulation rates determined from either present thickness or decompacted thickness due to compaction. We propose to use solid grain thickness to calculate sediment-accumulation rates so as to remove the compaction effects.

Bulk sediment mass accumulation rates (MARs) (in grams per square centimeter per thousand years) are calculated from linear sedimentation segments and dry bulk density data (grams of dry sediment per wet volume; in grams per cubic centimeter) (see "Index Properties" in "Physical Properties"). Only those samples with both dry bulk density and nearby carbonate data (within 4 cm) were used to calculate …

Jan 01, 2003 · However, assuming that an inventory of excess 210 Pb in the sediment column and 210 Pb activities of the depositing particles are constant over several decades, a mean accumulation rate can be calculated by the following equation (Oguri et al., 1997): (2) wP=λΣ, where w is the mean sediment accumulation rate (g cm −2 yr −1), P is the 210 Pb activity in depositing particles (dpm g −1), λ is the … Author: Kazumasa Oguri, Eiji Matsumoto, Masatoshi Yamada, Yoshiki Saito, Kazuo Iseki Publish Year: 2003

A compilation of nearly 25,000 rates of sediment accumulation shows that they are extremely variable, spanning at least 11 orders of magnitude. Much of this variation results from compiling rates determined for different time spans: there is a systematic trend of … Created Date: 20160809003349Z

Sediment accumulation rates in the deep sea are measured in centimeters to as little as millimeters per thousand years. Therefore, if particles were moved below the sediment–water interface by burial alone, the oxidation of organic matter, which occurs on timescales of months to decades, would take place only in the upper millimeter of the sediment column.

The average bulk sediment accumulation rates that correspond to these segments are 0.5 g/cm 2 /k.y. (segment 3) and 1.9 g/cm 2 /k.y. (segment 2). By contrast, the upper Miocene-Pleistocene was characterized by continuous sedimentation (Fig. F23 ), although the bulk accumulation rate decreased slightly through this interval, from 1.3 g/cm 2 /k.y. at 5.8 Ma to ~1.0 g/cm 2 /k.y. in the youngest …
