Abstract
This paper describes a new method for improved estimation of the parameters of a semi-empirical land uplift model of Fennoscandia, introduced by Tore Påsse in 2001. The behaviour and the basis of the land uplift model parameters are also evaluated. The ongoing land uplift in the Baltic Sea region is due to the rebound of glacial stress caused by the most recent ice age 115,000-10,000 years before present (BP). The improved methodology for the land uplift model parameter estimation presented in this study is based on regional variations in bedrock properties and download. The parameters are computed using ancient shore level positions and information about the prehistoric population in Finland. Because of the uncertainties and inaccuracies in the radiocarbon dating and the shore level estimations, Monte Carlo simulation was employed for the estimation of the parameter distributions. The resulting parameter estimates indicate the possibility of local variations in land uplift in Finland.
