This dataset provides Loss-on-ignition (LOI) data for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010. LOI values (%) are presented against both depth (m) and age (ka BP). The LOI dataset was used to provide information on Eemian landscape dynamics at Sokli (Plikk et al., 2016). A total of 112 samples were analyzed for LOI. Subsamples of 1 cm3 were dried in a 105 °C oven for 24 hrs before being placed in a furnace at 550 °C for 4 hrs and at 950 °C for 1 hour. Loss-on-ignition was calculated by comparing the dry weight of the samples before and after combustion at 550 °C following Heiri et al. (2001) and results are expressed as a percentage. The analyses were performed in the laboratories of Stockholm University, Sweden.

Further funding was provided by Swedish Nuclear Fuel and Waste Management Company (SKB) and Bolin Centre for Climate Research (Stockholm University).
