The first Ukrainian international geophysical school, the Field Camp in Ukraine 2017, was held on the basis of the Taras Shevchenko National University of Kyiv at the end of the summer. The event was only possible by activity of SEG Student chapter, which operates on the basis of the Institute of Geology, and with the support of the Society of Exploration Geophysicists (SEG), the Norwegian Geophysical Company TGS, the Ukrainian Enterprise Transit Technologies, and a number of other companies acted as partners and sponsors.
In the last five years, students have had the opportunity to attend student leaders' symposia (SLS) and SEG conferences. The experience of participating in international seminars, conferences and field schools influenced students of the student cell of SEG. Its president Anatoly Chernov and vice-president Oleg Loshakov have been looked for opportunities for the summer school of near-surface geophysics in Ukraine for a long time. Various projects in different venues were submitted, in particular, Chernobyl and Kamyanets-Podilsky. SEG pays special attention to the safety of the participants, so it has won a project for developed and picturesque place of Kamyanets-Podilsky. The Society of Exploration Geophysicists has provided a grant of $ 3,200. Postgraduate student Anatoly Chernov could no longer engage in the embodiment of his soul, since he became the youngest participant of the 22nd expedition at the Ukrainian Antarctic station "Academician Vernadsky". Therefore, the main responsibility for the implementation of the event layed on the shoulders of Oleg Loshakov. He appealed to the head of the Department of Geophysics Sergiy Vizhva, who helped by the advices and geophysical equipment. Director of the Institute of Geology Volodymyr Mykhailov gave an opportunity to arrange the accommodation of the participants of the hostel of the university. Magnetometers and an array for electrical resistivity tomography (ERT) provided by the laboratory Department of Geophysics.
The Kyiv Engineering Research and Research Institute "Energoprojekt" has allocated seismic equipment and sent its employee for measurements. This was a former university graduate Andrew Loboda. Maria-Valery Ignatyeva as the resident of Kamyanets-Podilsky helped in contacts with local authorities. Oleg Loshakov repeatedly traveled to Kamyanets-Podilsky to discuss various issues, in particular, the location for the participants, interesting sites for research and cultural program. The main organizers of the summer school were bachelor's graduates of the Institute of Geology: Oleg Loshakov, Yaroslav Popko, Maria-Valery Ignatieva and Natalia Rusachenko. Students of the Taras Shevchenko National University of Kyiv: Oleg Petrokushin, Maria Baryshnikova and Polina Berezina alot done for Geophysical Field Camp. Among foreign participants in the field camp were students: Ulyana Dzoba (Ivano-Frankivsk National Technical University of Oil and Gas, Ukraine), Ana Maria Hreniuc Morosan (University of Bucharest, Romania), Antonio Drnasin, Damjan Ostrelic and Marko Repac (University of Zagreb, Croatia); Presidents of the student chapters Martin Mazanec (Charles University of Prague, Czech Republic), Mykolaj Skorupa and Paulina Janusz (University of Arhus, Denmark), president of the student chapter of Zbigniew Wilczynski and Malwina Natkaniec (Krakow Mining and Metallurgical Academy (AGH), Poland), Rana Nafea (Aina Shams University, Egypt) and Khalid Abbas (Quaid-e-Azam University, Pakistan) which has working at StatOil in Norway.
Participants after lecture in Institute of Geology
The event took place during the week from 22 to 29 August 2017 at Kyiv and Kamyanets-Podilsky. The first part of the field school was team familiarity and lectures about geology and geophysics in Ukraine. On August 22, at the Institute of Geology, the participants presented their SEG chapters and opportunities for work in the geological field. After dinner, a sightseeing tour of Kyiv was held. On August 23, a course of lectures devoted to geological resources of Ukraine and near-surface geophysics took place. Volodymyr Mykhailov, Director of the Institute of Geology, spoke about the mineral resource base of Ukraine. Representatives of the Department of Geophysics associate professor Pavlo Kuzmenko made a report on near-surface seismology, associate professor Pavlo Gryshchuk have considered the basics of electrical tomography, and a senior research scientist, Ksenia Bondar spoke about the application of magnetometry for archeology. Director of LLC "Transient Technologies" Volodymyr Ivashchuk reviewed the methods of Ground Penetrating Radar (GPR) for archeological and engineering tasks. The lecturers and participants received certificates and T-shirts with the emblem of the first Ukrainian international geophysical school in Ukraine under the auspices of SEG.
The second part of the geophysical school was as field camp . On August 24, the participants arrived in Kamyanets-Podilskyi, where they had an excursion around the city. The following two days have used for field surveys. Participants were divided into four teams. They performed geophysical surveys using different methods and on new locations. Among them were virmenian bastion, places near ratusha and old castle, and his inside. As a result, all participants had the opportunity to master four geophysical methods. Ksenia Bondar was managed magnetic surveys because has extensive experience in these investigations.
Magnetometric survey allowed in the plan to find objects that may be associated with hidden underground wells, basements, tunnels, etc. Oleg Loshakov conducted geo-radar measurements. The results of this survey revealed in the vertical plane various heterogeneities under the surface of the earth. Two georadars of Ukrainian production "VIY" with frequency of electromagnetic oscillations of 125 and 300 MHz were used. Yaroslav Papko who already had field skills of electric surveys managed electric resistivity tomography. The electric imaging determined the apparent resistivity in the vertical plane. The array using 64 electrodes was created at the department of geophysics of the University. Andriy Loboda conducted the seismic surveys.
The methods of refracted and reflected waves were performed to establish boundaries between layers and objects. The combination of geophysical methods allowed to obtain more reliable information. The third day was devoted to excursions and materials processing. Participants of the field camp visited the gypsum cave "Verteba", which is a museum of Trypillian culture. After the trip, a guided boat trip took place along the huge reservoir of the Dniester River near the Bakota, where a cave monastery and three healing springs were located on the shore. After returning to the base, the participants processed and visualized geophysical data. A move from Kamyanets-Podilsky to Kyiv took place on August 28.
Pavlo Gryshchuk and Polina Berezina carried out photographing of the Field geophysical school. Foreign students were pleasantly impressed with the fact that the georadars were made in Ukraine, and in particular that the array for electric resistivity tomography was created at the Department of Geophysics of the University of Kyiv. A student from Croatia showed interest in studying at the Institute of Geology at the postgraduate study.
The implementation of the international geophysical camp was the sign event, as in 2017, it was 15 years since the foundation of the SEG student cell at Taras Shevchenko National University of Kyiv. As a result, 19 participants from 8 countries of the world (Ukraine, Poland, Romania, Egypt, Denmark, Czech Republic, Croatia, Pakistan) during the week gained practical experience in applying geophysical methods for solving near-surface and archaeological problems. The object of research was one of the perls of Podillia are Kamyanets-Podilsky’s fortification constructions.
Due to support of the Ministry of Culture of Ukraine, within the boundaries of the old city and Kamyanets-Podilsky Castle, a number of high-precision studies were conducted to find out the location of underground tunnels, the remnants of the foundations of defense and religious structures and other objects that were lost during tense wars. Methods of near-surface seismic surveying, electromotography, magnetic survey and geo-radar sensing are able to localize drainage channels, galleries, underground passages and any other cultural heritage that has been forgotten for hundreds of years. As a result, more than ten different locations were captured and received gigabytes of valuable information that is currently in process of processing and interpreting.
The purpose of the field camp, in addition to obtaining professional knowledge and skills, was to bring international participants closer to the beauty of Ukrainian nature and culture. Therefore, it was important to get acquainted with the beauty of Podillya, routes along the Dniester canyon and excursions to local caves.
Thus, students of the Institute of Geology conducted a unique project aimed at increasing the country's cultural heritage and establishing international relations between the Ukrainian and world scientific community.
