Timothy Weiler Linick died on June 4th, 1989. He was a dedicated researcher, and an important part of the NSF Accelerator Facility for Radioisotope Analysis at the University of Arizona. He will be remembered for his care and attention to details, especially in the calculation and reporting of radiocarbon dates. He made important contributions to the fields of oceanography and tree-ring calibration of the 14C time scale.

A Site

The abrupt millennial-scale changes associated with the Younger Dryas (YD) event (“chronozone”) near the dawn of the Holocene are at least hemispheric, if not global, in extent. Evidence for the YD cold excursion is abundant in Europe but fairly meager in central North America. We are engaged in an investigation of high-resolution environmental changes in mid-North America over several millennia (about 10,000 to 14,000 BP) during the Late Glacial–Early Holocene transition, including the YD interval. Several sites containing logs or stumps have been identified and we are in the process of initial sampling or re-sampling them for this project. Here, we report on a site in central Illinois containing a deposit of logs initially thought to be of YD age preserved in alluvial sands. The assemblage of wood represents hardwood (angiosperm) trees, and the ring-width characteristics are favorable to developing formal tree-ring chronologies. However, 4 new radiocarbon dates indicate deposition of wood may have taken place over at least 8000 14C yr (6000–14,000 BP). This complicates the effort to develop a single floating chronology of several hundred years at this site, but it may provide wood from a restricted region over a long period of time from which to develop a sequence of floating chronologies, the timing of deposition and preservation of which could be related to paleoclimatic events and conditions.

Accuracy And Precision

It is clear that radiocarbon researchers take a forward view towards the improvement of accuracy and precision in dating. Unfortunately, archaeologists base much of their research on the published dates produced in the past. Archaeologists and other users of radiocarbon dates should understand the limitations associated with past dates. This article addresses these limitations by looking at a large number of routine radiocarbon dates associated with a block of English tree-ring chronologies, the true ages of which are now known within close limits. My conclusion supports the idea of global multiplication factors as proposed by the International Study Group (1982).

The Bronze Age

The use of an absolute chronological framework based on tree-ring calibrated C-14 dates has been recently proposed by D. F. Easton in his attempt “… to come to grips with the crucial and difficult dating of Troy” (Easton 1976:146). Easton points out that unlike Tarsus, whose relative dating vis-a-vis Mesopotamia and Egypt is stable, Troy's relative chronology is not agreed upon and this “impinges not only on Anatolia, but on the Aegean and Bulgaria as well”.In establishing his chronology Easton uses, in addition to “the normal comparative methods”, two sources: (a) radiocarbon dates which, after calibration, especially when using Suess's calibration curve, affect both relative and absolute dating, (b) his reassessed stratigraphy of the Bronze Age levels at Troy (Easton 1976; 1977).Easton in his new chronological structure has not taken into consideration certain facts and opinions surrounding tree-ring calibrated radiocarbon dating. In view of the persisting controversy regarding this scientific dating method, it is premature, at least as far as Anatolia is concerned, to replace the relative dates derived from historical synchronisms with calibrated “absolute” C-14 dates.

Correlation Problem

AbstractTwo long series of samples from Tikal, Petén, Guatemala, have been dated by the radiocarbon method for the purpose of limiting the range of possible correlations of the Maya calendar with the Christian. These samples from lintel and vault beams were selected from latest-growth portions of the beams which were presumably cut at times corresponding to Maya dates carved on lintels of two temples. Christian dates for dedicatory Maya dates of the lintels are calculated according to five correlation hypotheses, and are compared with radiocarbon dates for ten beams from Temple IV and six from Temple I. These new radiocarbon dates are shown to be closely related to “absolute” ages by means of radiocarbon counts of tree-ring-dated samples of the same period. The radiocarbon results support the 11-16 (Goodman-Thompson-Martinez) correlation. Attention is given to previous radiocarbon tests by other laboratories of beams removed from Tikal many years ago which seemed to favor the 12-9 correlation in Spinden or Makemson variants. With the aid of new radiocarbon dates for similar samples, reasons for the differences in results are discussed.

Swiss Lake

Comparison of the radiocarbon content of a series of samples of dendrochronologically dated bristlecone pine wood with that from trees for which a so-called floating tree-ring chronology has been established makes it possible to determine an empirical age for this floating tree-ring series based upon the age of the wood used for comparison. For the case of the Swiss Lake Dwellers, the difference between conventional radiocarbon dates and the age values determined in this manner amounts to about 800 years. The age of the floating chronology was determined within a standard error of less than 40 years. The measurements indicate that the dwellings were constructed during the 38th century B. C.

Egyptian History

A fundamental aspect of ancient Egyptian history remains unresolved: chronology. Egyptologists (and researchers in related fields that synchronize their studies with Egypt) currently rely on a variety of insufficiently precise methodologies (king lists, radiocarbon dating, etc.) from which to derive seemingly “absolute” dates. The need for genuine precision has been recognized for a century, as has the potential solution: dendrochronology. This manuscript presents a case for further progress toward the construction of a tree-ring chronology for ancient Egypt.

Calendar Dates

We propose a simplified approach to the calibration of radiocarbon dates. We use splines through the tree-ring data as calibration curves, thereby eliminating a large part of the statistical scatter of the actual data points. To express the age range, we transform the ± 1 σ and ± 2 σ values of the BP age to calendar dates and interpret them as the 68% and 95% confidence intervals. This approach bypasses the conceptual problems of the transfer of individual probability values from the radiocarbon to the calendar age. We have adapted software to make this calibration possible.
