Paleoproductivity and organic matter sources in Late Quaternary Lake Ontario

“…All radiocarbon dates were converted to calibrated ages using INTCAL09 (Reimer et al, 2009). Additional information used to construct the age-depth model included pollen stratigraphy (Carmichael et al, 1990;McAndrews, 1994;Pippert et al, 1996), seismic stratigraphy (Hutchinson et al, 1993), magnetic properties (Carmichael et al, 1990) and previously reported radiocarbon dates (Schroeder and Bada, 1978;Silliman et al, 1996;Anderson and Lewis, 2012) (Table 2). These data were combined to produce a nonBayesian, linear interpolated age-depth model using the computer program CLAM (Blaauw, 2010), which provides a probabilistic age range for each depth.…”

“…All radiocarbon dates were converted to calibrated ages by CLAM using INTCAL09 (Reimer et al, 2009). Three radiocarbon dates were used along with information gathered from previous studies of Lake Ontario to establish the chronology (Carmichael et al, 1990;Hutchinson et al, 1993;McAndrews, 1994;Pippert et al, 1996;Silliman et al, 1996;Anderson and Lewis, 2012). Table 1 Radiocarbon dates were obtained at the University of Arizona AMS Laboratory in Tucson, AZ, USA.…”
