Radiocarbon and del 13C was determined on dissolved organic carbon collected from Imnavait Creek 1990 and 1991.

Abstract: 

Del 13C was determined on dissolved organic carbon from Imnavait Creek water collected from the fourth pond upstream of the Imnavait Creek flume in 1990 and 1991. Radiocarbon was determined on a sample in each year.

Methods: 

Creek water was collected from the fourth pond upstream of the Imnavait Creek flume. Collected water was placed in 4 liter beakers, acidified with HCL, and evaporated with an electric hot plate. Dried organic matter was removed from the beaker walls with a metal spatula and stored in scintillation vials. Radiocarbon activities and del 13C measurements were performed on the dried DOM.

del 13C = [(13C/12C sample / 13C/12C standard) - 1] x 1000
