From: Radiocarbon evidence of river transport and food web uptake of old carbon in Lake Athabasca, Canada
Radiocarbon (fraction modern carbon; FMC) and carbon stable isotope (δ13C) values of organic carbon in surface sediment at sites along a transect in western Lake Athabasca. For radiocarbon, data points represent the mean and standard deviation of 3 field replicates per site. For δ13C values, data points are individual measurements or the mean and standard deviation of field duplicates per site.
