Additional information
It is assumed that this date was not previously corrected for isotopic fractionation. A marine reservoir correction is needed.
BeCs-3, Brown: Recovered materials are treated as a single component representing intermittent occupation from 1300 BP to European contact. Quahog shells were found scattered through the matrix, much like the lithic and ceramic materials, rather than being concentrated in a shell heap. In addition to four radiocarbon dates, four thermoluminescence dates were obtained from ceramic sherds submitted with a sample of associated soil: Alpha-2354 (BeCs-3: 1147), 370 +/- 50 BP, exhibited fading, a sloping plateau and soil radon loss; Alpha-2355 (BeCs-3: 1148), 1350 +/- 60 BP, same characteristics as Alpha-2354; Alpha-2356 (BeCs-3: 1149), 250 +/- 40 BP, experienced soil radon loss; Alpha-2357 (BeCs-3: 1150), 230 +/- 30 BP, exhibited fading and a sloping plateau.
