A Holocene pollen record from the Laptev Sea shelf, northern Yakutia
Holocene shelf deposits from the Laptev Sea shelf (northern Yakutia) were investigated with palynological means. Data were obtained from a 467-cm-long sediment sequence from the southeastern Laptev Sea (74°30 N/136°00 E). The chronology of the core reaches back to 9.4 calendar years (cal. ka), yield...

Holocene shelf deposits from the Laptev Sea shelf (northern Yakutia) were investigated with palynological means.
