Table 2. Estimated sedimentation (cm/yr) and mass accumulation (g/cm -yr) rates for cores from stations 3C (1981) and 522 (1992) based on molecular stratigraphy...

The estimated sedimentation and mass accumulation rates for three time periods (1955-1965, 1965-1971, 1971-1981) at station 3C are reasonably consistent with the historical trends in solids emissions from the outfall system (cf. Table 2, Fig. 6). The sedimentation rates for station 522 during the same time periods are similar to those for station 3C. However, mass accumulation rates are systematically higher at station 522 than at station 3C, and there is a marked increase in both sedimentation rate and mass accumulation rate in the 1981-1992 period based on molecular stratigraphy (station 522 only). The latter observation is significant because emissions of wastewater effluent solids from the LACSD outfall system during the post-1981 period continued to decline (see Fig. 5 in Eganhouse and Pontolillo, 2000). Thus, the increase in sedimentation for the period 1981-1992 near station 522 (and presumably 3C) cannot be ascribed to an overriding influence of the outfall system.
