Exploring short-term ecosystem dynamics in connection with the Early Holocene Saksunarvatn Ash fallout over continental Europe
Highlights: • A single Saksunarvatn Ash layer was detected in two varved lake cores from N-Germany. • The ash layers in the two cores are dated to 10,282 ± 45 and 10,264 ± 24 cal. BP. • Palynological and geochemical analysis were conducted in proximity of the ash layers. • Environmental disturbance,...
