- Comments
- MbDj-1, Anarnitung: It contains 15 Thule winter houses, but the site is almost completely destroyed. Schledermann (1975: 85) was aware of the need to make a correction for the marine reservoir effect. He cited a study by McGhee and Tuck (1976), then in manuscript, which had explored a constant correction of -400 years but had concluded by ignoring all sea mammal dates. Schledermann considered both approaches to be extreme. By considering his radiocarbon dates in relation to stylistic traits on recovered harpoon heads, he elected to subtract 200 years from the uncorrected means of the dates. Had he first corrected his dates for isotopic fractionation, the -400 year correction would have yielded very similar results, within measurement error.
