centers

Revolutionary new advances in radiocarbon dating techniques have enabled scientists to more precisely determine the chronology and dynamics of Viking Age trade networks based on a medieval Danish Viking center near Ribe, Denmark. To be published today in the journal Nature, the Danish Viking center study uses a technique that pinpoints radiocarbon data to a single year. In the twentieth century, radiocarbon dating resulted in sweeping changes in archaeological techniques that considerably expanded our knowledge of the past. Further advances occurred when radiocarbon data was calibrated to calendar years and could be applied to increasingly small samples. Using single tree rings and rapid changes in levels of atmospheric carbon during solar particle events (SPE) or years of extreme solar flares
