Das radioaktive Kohlenstoffisotop 14C, auch Radiokarbon genannt, ist ein wichtiger Informationsträger für die Geowissenschaften. Es hilft, unser Verständnis von Klimaprozessen, der Sonne, des Geodynamos und des Kohlenstoffkreislaufs der vergangenen 55 000 Jahre zu verbessern. Moderne Messmethoden erlauben auch 14C‐Messungen an Kleinstproben. Das verringert die Unsicherheiten in den aktuellen IntCal20‐Alterskalibrationskurven...
A variety of palaeoclimatic records show a shift towards cooler, wetter and windier conditions in Europe around 2800 cal a BP. The shift broadly coincides with an increase of the atmospheric 14C concentration, suggesting a connection between solar activity variations and climate change. Here we investigate a peat record from Undarsmosse in southern Sweden. In a previous study, based on a low‐resolution...
Snowball, I., Muscheler, R., Zillén, L., Sandgren, P., Stanton, T. & Ljung, K. 2010: Radiocarbon wiggle matching of Swedish lake varves reveals asynchronous climate changes around the 8.2 kyr cold event. Boreas, Vol. 39, pp. 720–733. 10.1111/j.1502‐3885.2010.00167.x. ISSN 0300‐9483.
A series of nine radiocarbon measurements obtained at increments of 50 years was used to wiggle match varved sediments...
