Transatlantic exploration took place centuries before the crossing of Columbus. Physical evidence for early European presence in the Americas can be found in Newfoundland, Canada 1 , 2 . However, it has thus far not been possible to determine when this activity took place 3 – 5 . Here we provide evidence that the Vikings were present in Newfoundland in ad  1021. We overcome the imprecision of previous age estimates by making use of the cosmic-ray-induced upsurge in atmospheric radiocarbon…

Single-year radiocarbon dating anchors Viking Age trade cycles in time
TLDR
Disturbances in the radiocarbon record anchor a precisely dated archaeological stratigraphy of a medieval trading emporium in Denmark in time, revealing that the Viking expansion was associated with competition for trade routes rather than with raids.
Dendroarchaeology in Europe
Human evolution was strongly related to environmental factors. Woodlands and their products played a key role in the production of tools and weapons, and provided unique resources for constructions
In praise of archives (and an open mind)
A recent study dating Viking presence in America to a precise year was only possible thanks to long-term conservation of archaeological finds. It also arose from curiosity, interdisciplinarity and

The calibration of radiocarbon dates by means of a master calibration curve has been invaluable to Earth, environmental and archeological sciences, but the fundamental reason for calibration is that
Radiocarbon-based approach capable of subannual precision resolves the origins of the site of Por-Bajin
TLDR
This analysis shows that the construction of Por-Bajin started in the summer of 777 CE, a foundation date that resolves decades of debate and allows the origin and purpose of the building to be established.
Population genomics of the Viking world.
TLDR
It is concluded that the Viking diaspora was characterized by substantial transregional engagement: distinct populations influenced the genomic makeup of different regions of Europe, and Scandinavia experienced increased contact with the rest of the continent.

ONE THOUSAND YEARS AGO, the Old World and the New stood face to face in the Strait of Belle Isle. The landing of the Norse on the shores of North America was not the result of a sudden journey but

TLDR
The Viking diaspora was characterized by substantial foreign engagement: distinct Viking populations influenced the genomic makeup of different regions of Europe, while Scandinavia also experienced increased contact with the rest of the continent.
A Critical Review of Radiocarbon Dating of a Norse Settlement at L'Anse Aux Meadows, Newfoundland Canada
Recent progress in high-precision calibrations of radiocarbon dates has led to evaluations of earlier research. This has been the case with dates from the Norse settlement at L'Anse aux Meadows which
Paleoenvironment and the archaeological record at the L'Anse Aux Meadows Site, Newfoundland
Archaeological evidence from the marine terrace and fen at the site indicates brief episodic occupation for over 5000 years. Five cultural episodes have been identified, although the site is renowned
A signature of cosmic-ray increase in ad 774–775 from tree rings in Japan
TLDR
It is argued that neither a solar flare nor a local supernova is likely to have been responsible for the increase in 14C concentrations in tree rings of Japanese cedar trees, and the data are consistent with the decadal IntCal 14C data from North American and European trees.
