  • SEPTEMBER
    • On September 7-14, the scientists of the Department of Lithospheric Research took part in field work along the deep seismic sounding profile "TTZ-South". The experiment was conducted in cooperation with colleagues from the Institute of Geophysics of the National Academy of Sciences of Ukraine. The beginning of the profile was located ~ 26 km west of Radom, then the profile ran to the border with Ukraine, through the eastern periphery of Lviv to the Ukrainian-Moldovan border. The total length of the profile is ~ 550 km, of which ~ 230 km were on the Polish side and 320 km on Western Ukraine. About 320 short-period seismic devices were placed along the profile. On the Polish side 146 (86 Reftek 125 - Texan and 60 DATA-CUBE) and on the Ukrainian side, 175 (150 DATA-CUBE and 25 Reftek 125A - Texan). DATA-CUBE stations placed on the Ukrainian side came from the GeoForschungsZentrum (GFZ) equipment pool in Potsdam. There were also 11 strong seismic energy sources on the profile at regular intervals. Subcontractors responsible for the implementation of seismic sources were oil exploration companies Geofizyka Toruń S.A. (in Poland) and State Geophysical Enterprise "Ukrgeofizika" (in Ukraine).

      Interpretation of registered seismic sections will allow a better understanding of the geodynamic processes that took place in this region of Central Europe. Works on the Polish side were carried out as part of the HARMONIA 8 grant no. NCN 2016/22/M/ST10/00347 granted to the Institute of Geophysics of the Polish Academy of Sciences by the National Science Center. More information about the project can be found here.

  • January
    • On 22-31.01.2018 in Istanbul took place the 1st International Elite PhD Course "Deep Earth Processes and its Surface Expression" organized by the ITU Eurasia School of Solid Earth Geosciences. Two employees of our department took part in the course. The event was an excellent opportunity to supplement knowledge and benefit from the rich experience of lecturers prof. Peter Molnar (University of Colorado at Boulder, USA) and prof. Antony Watts (Oxford University, UK). Meetings with other participants of the course were an opportunity to establish cooperation with leading research centers. The course was completed with a field trip, which, apart from learning the history of the geological structure of western Turkey, allowed for a better understanding of the deep geological processes and their effects manifesting in the relief of the terrain among others the influence of the North Anatolian Fault..

  • On 9-11.01.2018, a working meeting was held in Warsaw as a part of the KNIPAS project, in which participated a representative of the Alfred Wegener Institute. As part of the meeting, the data registered in OBS type stations in the area of ​​Knipowicz Ridge (Svalbard) have been exchanged. Arrangements considering the division of work on the interpretation of the data and a schedule for further cooperation were established.

    • Organization of working meeting in Warsaw as part of the international project of deep seismic soundings RomUkrSeis (6-7.12.2017).
    • As part of the NCN grant "Determination of Seismic Anisotropy in Lower Silesia" in October - December, the staff of the Department of Lithospheric Research deployed 21 highly-sensitive seismic stations in the region of Dolny-Śląsk and Sudety Mountains for a period of about 1.5 years. Recorded data from local, regional and distant (teleseismic) earthquakes will be used to determine the parameters characterizing anisotropy within the crust and upper mantle of the Earth. The results of modeling will allow to determine the structure and deformation of rocks building anisotropic layers.

      We would like to thank the people and institutions that allowed us to place the equipment.

During the meeting, the representative of the Institute of Geophysics of the Polish Academy of Sciences delivered a presentation on the state and use of ocean bottom seismometers at the Department of Lithospheric Research. This event was used to exchange experiences gathered during maritime work and was an excellent opportunity to establish cooperation not only strictly scientific-research but also developmental. Additionally, the issues of open access to data and their processing in the Orfeus system were raised.

Data from recorded seismic shocks from a period of 288 days will allow investigation of the structure and processes taking place in the Knipowitch ridge.

  • May
    • At the invitation of the University of Uppsala on 23.05-06.06, the staff of the Department of Lithospheric Research participated in seismic refraction fieldwork in Sweden. The experiment was conducted in cooperation with the Universities of Copenhagen, Oslo and GFZ Potsdam. Along the "BASIC" profile of ~ 560 km there were about 600 field seismic stations, including 158 Polish (short-period: 88 Reftek 125-Texan and 60 DATA-CUBE and 10 CMG-6T Guralp broadband). Seismic energy was provided by 7 blasting points containing 360 to 500 kg TNT/dynamite loads, which were detonated in nearby quarries. The registered energy from these shots allows for the the possibility of interpreting the structure of the crust and upper mantle of the Earth in central-eastern Sweden and separating the border between the Bergslagen and Ljusdal crustal blocks. The work was carried out under the grant no. 2015-05177 awarded to the University of Uppsala by the Swedish Research Council.

Training could take place thanks to kindness and cooperation with the Institute of Oceanography of the University of Gdańsk. Using the ship "Oceanograf - 2" we conducted training and immersion tests of OBSs to a depth of about 11 m, in the Gulf of Gdańsk. We checked the procedure and the ascent mechanisms for all 6 OBSs. Attempts have been made successfully and have helped operators gain experience in handling these complex devices before professional measurements on deeper "wide" waters.

      • May
        • ​From the end of March to the first days of May 150 field stations owned by our Department was set up on approximately 320 km profile, from Gdynia to Sulęcin (Lubuskie), along with the P2 profile of the POLONAISE'97 project. The purpose of our measurements was to record the seismic energy generated in the Gulf of Gdansk during the neutralization of seabed mines from the Second World War (FILM) conducted by the Maritime Office and Polish Navy. In total, we received recordings of six explosions with loads ranging from 400 to 600 kg of hexanite. Moments of explosions were recorded directly at sea. The results of the experiment are a significant extension of the P2 profile to the north-east, where the last blast point was located several dozen kilometers from the Baltic coast. Good cooperation of our Department with Polish Navy will give us the opportunity for future cooperation, where at moderate cost we can gain high energies from controlled explosions.

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.
