text01.docWord document50KText 01. This file describes a simple model to assess how the partitioning of carbon amongst its end-members changes between seasons (vascular plants, phytoplankton, and a pre-aged soil component). The model was applied for time periods in which the ∆14C of lignin phenols and FPOC was determined, with two different approaches used for the rising and high-water periods. This material is referenced in the main text in the last paragraph of Section 3.
ts01.docWord document98KBasic compositional data for the fine suspended sediment examined in the study.
ts02.docWord document72KThe concentration and radiocarbon content of dissolved organic carbon.
ts03.docWord document68KRadiocarbon data generated from the analysis of individual lignin phenols isolated from fine suspended sediment during September 2008, June 2009, and July 2009.
ts04.docWord document51KThe lignin phenol content of the fine particulate organic carbon sampled during September 2008, and June and July of 2009. Specifically, the weight of C derived from each lignin phenol was normalized by 100 mg of organic C (i.e., the lambda (λ) value). Further, the average abundance-weighted radiocarbon content of lignin phenols is for each sample is presented (the latter was calculated from the data in ts03.doc as well as the data in this table).

ts06.docWord document41KThe percentage of fine particulate organic carbon that is derived from phytoplankton, vascular plants, and soils. The table also contains an estimate of the ∆14C of the soil that is calculated from the mixing model presented in the auxiliary text.
