Stratigraphic units, basis

Lakewide Hg Accumulation. Mercury accumulation rates can be calculated for individual core sites as the product of the 210Pb-based sediment accumulation rate and Hg concentration in different strata. If enough cores are analyzed, whole-lake Hg inputs can be calculated by weighting the Hg flux of each core by the portion of the depositional basin it represents. In this study we calculate Hg loading for each lake on an areal basis for two time-stratigraphic units—modem (roughly the last decade) and preindustrial (before 1850)—according to eq 2 ... [Pg.58]
