We present new 14 C results measured on subfossil Scots Pines recovered in the eroded banks of the Drouzet watercourse in the Southern French Alps. About 400 new 14 C ages have been analysed on 15 trees sampled at annual resolution. The resulting Δ 14 C record exhibits an abrupt spike occurring in a...

We present new 14 C results measured on subfossil Scots Pines recovered in the eroded banks of the Drouzet watercourse in the Southern French Alps. About 400 new 14 C ages have been analysed on 15 trees sampled at annual resolution. The resulting Δ 14 C record exhibits an abrupt spike occurring in a single year at 14 300–14 299 cal yr BP and a century-long event between 14 and 13.9 cal kyr BP. In order to identify the causes of these events, we compare the Drouzet Δ 14 C record with simulations of Δ 14 C based on the 10 Be record in Greenland ice used as an input of a carbon cycle model. The correspondence with 10 Be anomalies allows us to propose the 14.3 cal kyr BP event as a solar energetic particle event. By contrast, the 14 cal kyr BP event lasted about a century and is most probably a common Maunder-type solar minimum linked to the modulation of galactic cosmic particles by the heliomagnetic field.
