Geophysical Survey of Salpausselkä Glacial Deposit near by the City of Hanko in Finland

In Finland we have lots of esker and end moraine deposits originated from the time of glacial period and from the time of glacial rebound. The purpose of this study is to investigate those deposits with different geophysical methods. We carried out ground penetrating radar, refraction seismic, and resistivity imaging measurements when investigating Salpaussekä end moraine near by the city of Hanko in Southern Finland. Moreover, we bored four reference boreholes and exploited all geological data in available when making the final interpretation. As a result of these studies, we identified different soil types and the topography of bedrock. We are also able to evaluate better the genesis of certain parts of Salpausselkä end moraine in the vicinity of the city of Hanko.
