NORSAR has rented 12 seismic stations from SISMOB for a period of 6 months, which were installed in Adventdalen (Spitsberg, Norway) between the 6th and the 16th of May 2014. The objective was to cover an area around the CO2 lab and record the ambient seismic noise during a water injection planned for August 2014. Six of the sensors are CMG 40 (Guralp, 60 s-50 Hz), six are Noemax (Agecodagis, 20 s-50 Hz). Taurus digitizers were employed with a sampling frequency of 100 Hz. At the time of the installation the Adventdalen river was still frozen, allowing to reach its northern side using a track vehicle. Most of the stations were installed on large blocks of rock (sandstone), in some cases requiring an additional cement base. Most of the stations recorded during the whole installation period; however, station STN04 stopped recording in the middle of June, station STN08 had problems recording continuous data starting middle of July (but was being repaired middle of August) and station STN10 did not record data apart from a very short period.
