The latter method often generates a conservative estimate of erosion rate Rohrmann et al.

In most instances, the 14C ages of ecofacts were statistically indistinguishable between the two contexts and support the relative chronological relationships established by excavation. Ivy- Ochs, R.

Findings related to human activity are, however, mainly restricted to continental settings. This approach, we suggest, allowed us to eliminate stratigraphic complexity as a source of variation in 14C measurements and to assess the taphonomic issues associated with dating different ecofacts. The age of the deposit and information detailing the removed sediment cover may also be used to estimate the wind erosion rate Clarke et al. As noted in previous studies, Phoca sp. In aclosed system the intermediate isotopes exist in so-called secular equilibrium, that is, their abundance ratios are such that each isotope decays at exactly the rate 1. The tree ring based chronology is constantly pushed back in time beyond the Holocene into the Late Glacial. The cutoff of 14C uptake death or deposition of the inorganic carbon marks the time zero of the radiocarbon clock and 14C activity measured in the material is used to calculate the time that elapsed since that event. The advance in preparation techniques helps to reduce the contamination of sample with modern or old carbon that could interfere with measurement of the correct 14C activity remaining in adated sample.

The objective was to investigate relative variation in the 14C age of ecofacts with the aim of establishing a hierarchy of dating suitability for Nunalleq that could more widely inform 14C sample selection on archaeological sites across the North American sub-Arctic and Arctic and Greenland.

In total, 16 samples were submitted for dating, comprising two sets of eight different ecofacts, one from each of two stratigraphically contemporary but spatially discrete contexts.

In most instances, the 14C ages of ecofacts were statistically indistinguishable between the two contexts and support the relative chronological relationships established by excavation. Owing to the complexities associated with interpreting and establishing the relative chronology of the deeply stratified sod deposits at Nunalleq, we adopted open-area excavation and single-context recording methods.
