Preparing the samples for measurement

Preparing the samples for measurement

After pre-treating the samples so that we can be absolutely sure that what we are dating is what we are interested in, the next step is to get the samples into a form which can be measured by accelerator mass spectrometry (AMS). To do this, our samples are first...

Counting and Cutting Tree Rings

Key to the wiggle-match dating method is radiocarbon dating samples through a known sequence. In our case, the known sequence is the structure of the trees which were used in construction of our crannogs. The rings within the trees represent, of course, single-years....

We are back at Loch Tay, this time to excavate at Milton Morenish Crannog. Again our objective is to sample timbers that we will date using dendrochronology, radiocarbon and Bayesian statistical analysis. Milton Morenish Crannog is located near the north shore of Loch...
