7/18/2016 · Large numbers of 14 C dates of the base and top of Holocene peat layers may be plotted in 14 C histograms in order to establish statistically a chronology of periods of essentially clastic sedimentation and peat formation. Due to the non-linearity of the 14 C time scale in terms of calendar years, clustering of 14 C dates on random peat growth may occur.

The application of AMS to dating terrestrial macrofossils is highly important, reducing potential contamination problems encountered with bulk sediment samples or humic acid extractions by either younger or older carbon sources (Olsson, 1986, MacDonald et al., 1987, Björck and Wohlfarth, 2001, Blaauw et al., 2004).

After students have read about dating with carbon-14, ask: Why do all organisms contain a small amount of carbon-14? (It circulates in the atmosphere and is absorbed by living matter.) Why is the ratio of carbon-14 to carbon-12 constant during an organism’s lifetime? (Carbon-14 is continually replaced.)

Global temperature record - Wikipedia

★ ★ ★ ☆ ☆

The global temperature record shows the fluctuations of the temperature of the atmosphere and the oceans through various spans of time. The most detailed information exists since 1850, when methodical thermometer-based records began. There are numerous estimates of temperatures since the end of the Pleistocene glaciation, particularly during the current Holocene epoch.

Age-at-depth histograms for these depths may be found in Figs 2(b) and 2(c). 5. Discussion Precise and reliable age models of palaeo-ecological archives are important for detailed recon- structions of past changes in climate. Radiocarbon dating, a technique which is often used for obtaining chronologies, requires thoughtful use of statistics.

ContaminationIn general, any organism containing carbon and that once lived in equilibrium with atmospheric 14 C can be dated by the radiocarbon method. Typical material for radiocarbon dating includes wood, charcoal and bones.
