16TH INTERNATIONAL RESEARCH SCHOOL
Geophysical monitoring of Yakutsk and its suburbs
Geophysics, ecology
Urbanization significantly changes environmental conditions. Living in a city, one is forced to expose himself to various factors that affect his health: atmospheric pollution, chemical waste. Among other factors, there are physical ones, such as increased noise levels, electromagnetic fields. Another important physical factor that is rarely considered is the content of aeroions in the air. Aeroions are charged air particles. They can be charged positively or negatively.
Sources of geophysical impact

It turned out that the lack of negative aeroions has a detrimental effect on health. According to sanitary rules and regulations the minimum allowable concentration of aeroions (per 1 cm3) for positive aeroions is 400 and for negative ones is 600, but often in urban conditions the actual values are lower than recommended. To monitor the content of aeroions in the air a complex of geophysical measurements is applied.

Aeroion counter MAC-01
The project participants will be invited to conduct multi-day geophysical monitoring in order to determine the content of aeroions in various areas of Yakutsk and the Lena River basin, as well as their change over time. The measurements will be carried out directly at the sites with scientific sensors and then processed using statistical methods. Besides, the state of the atmosphere will be monitored as well through specialized Internet resources.

Magnetometer MTM-01
Space weather website of ISTP
As a result of the work at the IRSchool, a map of the aeroion composition and variations of the magnetic field in certain areas of Yakutsk and rural areas in its suburbs will be created. It will also be investigated whether the aeroionic content changes during the day, and whether it is affected by magnetic fields in the city.
Requirements for participants:
  • Basic knowledge of physics and ecology.
  • Basic skills in Microsoft Office programs (Excel, Word, PowerPoint)
Tutors

Elena Krakhina

Moscow, Russia
Elena works as a research engineer at the Laboratory of Earthquake Prediction Methods at the Institute of Physics of the Earth, Russian Academy of Sciences, and as a senior lecturer at the Cartography Faculty of the Moscow Institute of Technology. She is currently working on her PhD thesis in Engineering Geology. As part of her thesis, she studies landslide processes, their development dynamics, and the factors that influence the activation of exogenous geological processes. As part of her scientific work, she also studies seismogravitational landslides and the influence of geomagnetic fluxes on seismic activity levels. She has served as a research mentor, preparing high school students for academic conferences and nationwide competitions—many of her students have gone on to become prize-winners and champions as a result of their work.
She organized and led research expeditions to the Utrish State Nature Reserve in the summer of 2023 and to the Ilmensky State Reserve in the summer of 2024. She also trained the Moscow city team as a scientific mentor for participation in the All-Russian Children's Environmental Forum—in 2024, the team took first place, and in 2025, they placed as runners-up.
She is a winner of the 5th International Award of the Federal Service for Supervision of Natural Resources (Rosprirodnadzor), "Ecology Is Everyone's Business," in the "Eco-Education" category.

Kirill Zenin

Moscow, Russia
Kirill works as a research engineer at the Institute of Geosphere Dynamics in Moscow and does geophysics, particulary – ionosphere study. He also decided not to limit himself to one field of science and at the same time studies pedagogy at the Institute of Education, harmoniously combining geophysics and education. Last year, he learned about the existence of research-based learning and the International Research School and decided to participate in such a school as a tutor by all means.
