  7. 7. Sank off Haiti, 1885
  8. 8. “ Detailed analysis of twelve samples of wood by Dr. David Etheridge, a wood scientist from Victoria, British Columbia, showed the ship was built either in Northern New England or the ” Maritime Provinces of Canada. NUMA.neth p://www.numa.net/press/080801.html

  22. 22. Roskilde
  23. 23. Skuldelev 2 30-m long, 3.8-m wide, 70 to 80-member crew
  24. 24. “ The most important limitation [of shipwreck archaeology]…is the virtual impossibility of ” deducing the shipyard where a vessel was built. Basch, 1972
  25. 25. “ It was possible to correlate the tree-ring curves from twelve planks and the keel and construct a chronology that spanned 248 years, ” representing the building phase of the ship. Bonde and Crumlin-Pederson, 1990
  26. 26. Roskilde

  28. 28. “ The Skuldelev-chronology fi ed perfectly with all the chronologies except the one for Belfast, which, as it turned out, did not cover the dating ” range for our curve. Bonde and Crumlin-Pederson, 1990
  29. 29. “ Based on these results we can conclude that the longship excavated in Denmark was built in the region of the Irish Sea, most likely in Dublin, ” in the second half of the 11th century. Bonde and Crumlin-Pederson, 1990

  32. 32. “ The result [of successful dendrochronological dating on ships] is o en so precise that every recognized theory ” which conflicts with it is immediately discredited. Bonde & Christensen 1982

  41. 41. “ The Holocene part of the 14C calibration is based on several millennia-long tree-ring chronologies providing an annual, absolute time frame within the possible error of the dendrochronology, which was rigorously tested by ” internal replication of many overlapping sections. Reimer et al., Radiocarbon, 2004
  42. 42. Cu ing dates Dates assigned to crossdated wood or charcoal specimens that possess evidence that the last ring present on the specimen was the last ring grown by the tree before it died.Source: Nash, Journal of Archeological Research, 2002
  43. 43. Noncu ing dates Dates assigned to crossdated specimens if there is no evidence indicating that the last ring present on the specimen was the last one growth before the tree died.Source: Nash, Journal of Archeological Research, 2002
  44. 44. Date clustering If a number of tree-ring dates from a given site cluster in one calendar year (or are very close together), one can infer that some substantial construction (or repair) occurred at that time.Source: Nash, Journal of Archeological Research, 2002
