Radiocarbon Calibration by Means of Varves Versus ¹⁴C Ages of Terrestrial Macrofossils from Lake Gościąż and Lake Perespilno, Poland

Abstract

ABSTRACT. This paper presents radiocarbon dates of terrestrial macrofossils from Lakes Go ci¹¿ and Perespilno, Poland.

Calibration of the 14C time scale: towards the complete dating range

“…These data also agree with the varved sediments from Lake Gosciaz (Goslar et al, 2000b), and with marine varves from the Cariaco Basin (Hughen et al, 1998a,b).The detailed A 14 C record for the last ca. 20,000 years shows millennium-scale fluctuations, superimposed on a long term increasing trend, resulting from a decreasing geomagnetic intensity and consistent with 10 Be records (Bard, 1997).…”

Preliminary Report of the First Workshop of the Intcal04 Radiocarbon Calibration/Comparison Working Group

“…The varved records from Lake Suigetsu in Japan (Kitagawa and van der Plicht 2000) and Lake Go ci in Poland (Goslar et al 2000) agree well with the "site-specific" reservoir corrected corals (T Goslar, personal communication 2000) and the new Cariaco Basin dataset but are not as high resolution as the Cariaco Basin and exhibit larger variability. It is anticipated that the atmospheric dataset for this portion of the curve will be based on the marine dataset with "site-specific" reservoir corrections and estimated uncertainties.…”

The chronology of abrupt climate change and Late Upper Palaeolithic human adaptation in Europe

“…yr BP. The IntCal04 Lateglacial dataset, as with IntCal 98 is, therefore, based predominantly on marine samples which are by definition affected by marine reservoir uncertainties (see, for example, Goslar et al, 2000Goslar et al, , 2001. Calibrating radiocarbon dates using these curves, therefore, introduces an additional uncertainty, the magnitude of which is difficult to assess at present with constant reservoir offset being assumed in most cases (Stuiver et al, 1998, Hughen et al, 1998a, 2004.…”
