NYAL Site Information Form International GPS Service for Geodynamics 0. Form Prepared by (full name) : Svein Rekkedal Date Prepared : 29-06-1999 Report Type : UPDATE Prepared Using : 1.1. Site Identification of the GPS Monument Site Name : Ny-Alesund Four Character ID : NYAL Monument Inscription : IERS DOMES Number : 10317M001 CDP Number : Date Installed : JAN-1993 Geologic Characteristic : PERMAFROST/MORAINE Bedrock Type : SEDIMENTARY Bedrock Condition : WEATHERED Fracture Spacing : over 200 cm. Notes : Investigations concludes that the reinforced concrete carrying the steel tower, most likely, is not well fixed to the solid bedrock. It is assumed that there might be a layer of frozen gravel separating the solid bedrock and the concrete. Additional Information : 2.
