alta_lake_210Pb_agesR Documentation

Alta Lake Lead-210 and Carbon-14 Ages

Description

The alta_lake_210Pb_ages object contains raw depths and ages for Alta Lake (Whistler, British Columbia, Canada) core AL-GC2 (Dunnington et al. 2016; Dunnington 2015). For these values, ages were calculated from Lead-210 activities using the constant rate of supply (CRS) model (Appleby and Oldfield 1983). The alta_lake_14C_ages object contains one uncalibrated Carbon-14 measurement from the same core. The alta_lake_bacon_ages object contains the combined result of the Lead-210 and the Carbon-14 ages as modelled by the rbacon package (Blaauw and Christen 2011).
