Hydrogeological Effects on Superconducting Gravimeter Measurements at Metsahovi in Finland

The purpose of this study is to gain a better knowledge of superconducting gravimeter (SG) data at the<br>Metsähovi Gravity Station in Southern Finland. SG data have a high accuracy (1 ngal) and are very sensitive<br>to various environmental and hydrogeological effects. So, before we are able to investigate their effects on<br>data we must isolate them and analyze their characteristics.
