What is the significance of carbon dating and how is it used by archaeologists?
In 1965, an NSF-funded investigator found a bacterium within the extreme temperatures of the recent springs in Yellowstone Park. By 1986, this leads to a DNA polymerase that can amplify tiny amounts of DNA, a robust tool for courts and biologists alike. In a significant reorganization, NSF establishes the Directorate for Engineering, giving new emphasis to engineering research. The award recognizes an outstanding younger researcher in any of the fields supported by NSF. The Office for the International Decade of Ocean Exploration is established. This is certainly one of a number of large-scale projects in oceanography that NSF has led or participated in.

If pieces of these three planks had been later discovered by archeologists, they might declare that the site had been occupied for 17,000 years, from about 37,000 to 20,000 BCE. The actuality may be that the site was solely occupied for fifty years from 2130 to 2080 BCE. If such accelerated decay really occurred, it’s possible that no matter 14C had existed before that time would have been converted again into nitrogen. This scenario would additionally clarify the age gradient seen in sedimentary rock strata.
