In the rugged landscapes of Iturup Island, part of the Southern Kuril Islands, a team of researchers led by Artem V. Degterev from the Institute of Marine Geology and Geophysics of the Far Eastern Branch of the Russian Academy of Sciences, has embarked on a groundbreaking study of the ultra-acidic thermal springs known as the “Blue Lakes.” These springs, discharging in the Kipyashchiy Stream valley on the slope of the active Baransky volcano, offer a unique glimpse into the geological processes that could have significant implications for the energy sector.
The field surveys conducted in July 2025 have revealed preliminary results that are already sparking interest in the scientific community. Degterev and his team have been studying the ultra-acid sulfate-chloride thermal springs, which are characterized by their extremely low pH levels and high concentrations of dissolved minerals. These conditions make them a natural laboratory for understanding the behavior of hydrothermal systems and the potential they hold for geothermal energy.
“These springs are not just geological wonders; they are windows into the Earth’s subsurface processes,” Degterev explained. “By studying them, we can gain insights into the mechanisms that drive hydrothermal activity and how we might harness this energy more effectively.”
The research is particularly relevant for the energy sector, as geothermal energy is increasingly seen as a viable alternative to fossil fuels. Understanding the dynamics of ultra-acidic thermal springs can help in the development of more efficient and sustainable geothermal power plants. The data collected from the Blue Lakes could provide valuable information on the stability and longevity of geothermal reservoirs, which are crucial factors in the commercial viability of geothermal projects.
Moreover, the monitoring of geological processes in these extreme environments can offer clues about the potential for other forms of energy extraction, such as mineral mining. The high concentrations of dissolved minerals in the thermal springs could indicate the presence of valuable mineral deposits, which could be exploited for commercial purposes.
Degterev’s team is also exploring the environmental impact of these hydrothermal systems. The ultra-acidic waters can have significant effects on the surrounding ecosystems, and understanding these impacts is essential for developing sustainable practices in the energy sector.
The preliminary results of this research were published in the journal ‘Геосистемы переходных зон’, which translates to ‘Geosystems of Transition Zones’. This journal is known for its focus on the study of geological processes in transition zones, making it a fitting platform for Degterev’s work.
As the research continues, the findings from the Blue Lakes could shape future developments in the field of geothermal energy and beyond. The insights gained from this study could lead to more efficient and sustainable energy solutions, benefiting both the environment and the economy.
In the words of Degterev, “This research is not just about understanding the past and present of these geological features; it’s about shaping the future of energy production.” As the world looks for cleaner and more sustainable energy sources, the Blue Lakes on Iturup Island could hold the key to unlocking new possibilities.
