  • MARCH
    • Monika Dec was granted PhD degree in Earth Sciences. Topic:
      "Differences in upper mantle structure based on P-wave seismic modelling for chosen tectonic units” 
    • Wojciech Gajek started his PhD studies in our Departament.
  • February
    • 4th - 20th February: seismic fieldwork was conducted nearby Niedzica, south of Lake Czorsztyn using 60 DATA CUBE recording seismic stations. The refraction experiment was realized along a 12-km 2D profile. The source of seismic energy were Vibroseis used for an independent reflection experiment commissioned by our Institute’s Department of Seimology and performed by Geofizyka Kraków. This work is a part of Grant no 112, directed by Mariusz Majdański. It is worth mentioning that we did a seismic experiment in harsh winter conditions. We had to face the challenges of burying the stations in deep snow, lower battery capacity and problems with the GPS signal under the snow layer.

  • January
    • Jacek Trojanowski was employed as a Research Assistant in the Departament.

  • September
    • First tests of our Ocean Bottom Seismometers were performed in an open swimming pool in Warsaw. We have been testing the function of remote surfacing triggered by the acoustic signal from the operator. As can be seen in the movie:

      the tests were successful!
    • 10th to 20th September: we participated in field work near Braniewo in Warmia, using 60 DATA CUBE recording stations. The refraction experiment consisted of a 2D 20 km long profile. The Vibroseis used for an independent reflection experiment commissioned by PGNiG were used as a source of seismic energy. This work is a part of an Grant no 112, directed by Mariusz Majdański.

Nie zdążyliśmy przed orką, która ukryła naszą aparaturę, mimo to udało się ją znaleźć!

  • august
    • 23th August to 2nd September we were participating in the seismic refraction field work along the RomSeis profile (275 km of the profile is in Ukraine and 400 km in Romania). Among 335 seismic recording stations constituting the profile, 150 were Polish. The seismic energy sources were 11 TNT explosions. The exact timing of the explosions were recorded using special devices constructed in our Departament. The experiment was a joint project in cooperation with the Institute of Geophysics of the Ukrainian Academy of Sciences and the Departament of Geophysics and Geology of the University of Buchrest..

  • November
    • 28th October to 15th November: field work was performed near Koło (Greater Poland) using 130 recording seismic station (Texans and Data CUBEs). The experiment was set in 3D and consisted of 6 intersecting profiles of total length of about 130 km. The Vibroseis used for an independent reflection experiment commissioned by Strzelecki Energia were used as a source of seismic energy. This work is a part of an Grant no 112, directed by Mariusz Majdański.

  • october 
    • Field work in Pomerania. We initiated a cooperation with the Maritime Office in Gdynia and the Polish Navy planning to record and use in our research the seismic energy from the detonation of the World War II misfires still lying the Bay of Gdańsk.
    • Maciej Trzeciak and Sebastian Białas started their PhD studies in our Departament.
    • Marta Cyz was employed as a Research Assistant in the Departament, in the Seismic Imaging Team.
    • We included 6 Ocean Bottom Seismometers (type  CMG-6TC OBS, produced by Güralp Systems Ltd), in our aparature base.

  • august
    • Field work on the refraction seismic profile GEORIFT 2013 was performed. The profile is 670 km long (310 km in Belarus and 360 km in Ukraine), consists of 14 shot points (7 locations both in Belarus and Ukraine, each shot is an explosion of approximately 600 to 1000 kg of TNT).  284 recording seismic stations were used in the experiment. 139 stations came from Warsaw: 89 Texan stations from the common Polish-Finnish-Austrian base and 50 new DATA Cube stations.

  • july
    • Mariusz Majdański initiated the Geophysical Research and Training Area on the grounds of the Observatory in Świder. It will be used to test new equipment and measurement and recording techniques from all the geophysical research fields. A 400 m profile is already marked. Seismic experiment along this profile was performed using DATA-CUBEs. Next experiments, repeated in the same shot and recording points will allow to compare and verify the quality of the results.
    • We included 50  DATA-CUBE, recording seismic stations produced by OMNIRECS, Germany in our aparature base.

  • May – june
    • Seismic experiment in Finland – the second part of the field work on the KOKKY profile in south Finland was conducted. Seismic energy generated by industrial activity in opencast mines and quarries was measured for about 45 days. 75 Texan seismic recording stations from the common Polish-Finnish-Austrian base were used.

  • April
    • 4th to 7th and 20th 25th April: workshops with our colleagues from the Institute of Geophysics of the Ukrainian Academy of Sciences dedicated to publish the results from our joint experiments DOBRE-2, PANCAKE, DOBRE-4 and DOBRE-5. We were also planning future common experiments for the years 2013 and 2014.
