ODM6 Shipwreck: Dendrochronological Analysis of 72 Wood Samples

26.040 Dreumel - wrak ODM6 contains dendrochronological data from a shipwreck discovered in the "Over de Maas" nature area. The dataset includes measurements from 72 wood samples, comprising 50 oak (Quercus spp.) and 22 ash (Fraxinus excelsior L.) specimens. It was created by Sjoerd van Daalen and last updated on 2026-05-18.

Use Cases

• Date the construction of a medieval shipwreck based on the most recent tree-ring dating in 977.
• Analyze wood sourcing and tree age by comparing the master curves for oak (26.040.M01) and ash (26.040.B08, 26.040.M02).
• Study the preservation and degradation of sapwood in archaeological wood samples, as mentioned in the description.
• Identify timber elements originating from the same tree through the intra-sample comparisons described.

Strengths

• Includes 72 individual wood samples for analysis.
• Provides a specific felling date for one sample (autumn/winter 977/978).
• Contains constructed master curves for oak (42 samples) and ash, facilitating comparative analysis.

Limitations

• One sample was not analyzed due to insufficient tree rings, and six ash measurements could not be included in a master curve.
• The estimated felling intervals may be over- or underestimated due to irregular observed sapwood rings.
• Column-level documentation is absent; field semantics must be inferred after download.
