Carbon dating artifacts

Carbon dating is somewhat accurate because we are able to determine what the ratio was in the unobservable past to a certain extent.By taking a carboniferous specimen of known age (that is, a specimen which we are able to date with reasonable certainty through some archaeological means), scientists are able to determine what the ratio was during a specimen's lifetime.Based on the artifact analysis and C14 dating, archaeologists have determined that material collected during GCI TERRA fiber optic cable installation is associated with the Thule culture*, the ancestors of modern Inuit. *The Western Thule culture comes from part of the widespread Thule culture that is clearly ancestral to the present-day Iñupiat people. GCI visited Kotzebue on several occasions to design the educational project described in the Memorandum of Agreement.Archaeologist Morgan Blanchard, Ph D brought some of the most compelling artifacts to the Native Village of Kotzebue Elder Council, Kotzebue Middle High School, and to a public event at the Northwest Arctic Heritage Center in January 2016.Artifacts are now stored in perpetuity at the University of Alaska Fairbanks Museum of the North.Analysis of artifacts indicates that the material comes from two previously identified sites, KTZ-00386 and KTZ-00347.

Carbon dating is thus accurate within the timeframe set by other archaeological dating techniques.Unfortunately, we aren't able to reliably date artifacts beyond several thousand years.Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating.Carbon (14C) dating was conducted on one piece of modified bone from each site.The calibrated date for site KTZ-00386 is AD 1210-1275 (about 806 years old), and site KTZ-00347 is AD 1260-1295 (about 756 years old).

Many scientists will use carbon dating test results to back up their position if the results agree with their preconceived theories.
