New Evidence Dates Viking Presence in North America to Precisely 1021 CE | |
Researchers pinpoint when the Vikings came to Canada. It was exactly 1,000 years ago https://www.npr.org/2021/10/21/1047797376/researchers-discovered-the-date-vikings-arrived-in-canada New Dating Method Shows Vikings Occupied Newfoundland in 1021 C.E. https://www.smithsonianmag.com/science-nature/new-dating-method-shows-vikings-occupied-newfoundland-in-1021-ce-180978903/ Evidence for European presence in the Americas in AD 1021 https://www.nature.com/articles/s41586-021-03972-8 Dendrochronology: What Tree Rings Tell Us About Past and Present https://www.environmentalscience.org/dendrochronology-tree-rings-tell-us The Norse in Newfoundland: L'Anse aux Meadows and Vinland https://journals.lib.unb.ca/index.php/NFLDS/article/view/140/236 Viking expeditions and raids https://en.natmus.dk/historical-knowledge/denmark/prehistoric-period-until-1050-ad/the-viking-age/expeditions-and-raids/ The scientific community has long accepted that the first Europeans to journey to North America were Viking explorers and settlers, not the expedition of Christopher Columbus - yet the exact timing of the earliest Viking expedition was unclear. Now, new evidence has allowed a team of researchers to pinpoint the precise year. The evidence consists of discarded pieces of wood found at L'Anse aux Meadows in Newfoundland, Canada, which show signs of having been cut by iron tools. The breakthrough came thanks to a rare cosmic occurrence - an enormous solar storm in the year 993 CE, which caused a spike in atmospheric carbon that can be seen in tree ring samples. Using radiocarbon dating, researchers identified tree rings from this year in the wooden artifacts and counted to the outer ring (when each tree was cut and stopped adding growth). The 28 layers between the outer ring and the ring with unusually high carbon provided the year of the Viking visit: 1021 CE, exactly 1,000 years ago. Members of the research team hope that these techniques can be applied to other archaeological finds across the world. The first link above is to a news brief from National Public Radio about the research findings and the radiocarbon dating techniques applied. The second link, to a piece from Smithsonian Magazine, explains how dendrochronological archives around the world provide evidence of a solar storm in the year 993. In the third link, interested visitors can read an open-access version of the original article in Nature in which the evidence for this discovery is laid out. The fourth link, from the organization Environmental Science, provides an overview of dendrochronology and its applications to archaeology. The fifth link is to an article from the journal Newfoundland and Labrador Studies that highlights the Icelandic chronicles written about the Viking voyages to North America: The Greenlanders' Saga and Erik's Saga. The final link is to a digital exhibition from the National Museum of Denmark that explores Viking trade and travel around the world, including dangerous journeys to Russian, Constantinople, and as far east as the Caspian Sea.
