Teleseismic data recorded at 52 permanent broad-band seismic stations in the Swedish National Seismic Network have been used to map Moho depth variation in the Baltic Shield. We use the receiver function technique to isolate signals associated with P to S conversion at the base of the crust. The delay times of this phase, and of crustal reverberations, are used to constrain Moho depth and crustal average VP/VS. For a majority of the stations in the study, well constrained results could be obtained and these are discussed in comparison to previous estimates of Moho depth in the area. Our results are found to be in very good agreement with previous estimates where these exist. For large parts of the area, estimates of Moho depth have not been available until now and the results of the present study serve as a valuable complement to constrain crustal thickness variation in the Baltic shield.
