Ecological and geochemical state of soils in the central part of the curonian Spit Peninsula, Kaliningrad Region, Russian Federation

The research results presented in this article were obtained during the expedition to the Curonian Spit in the spring of 2024 as part of the final of the All-Russian Championship “Limitless Expeditions” of the All-Russian public and State Movement of Children and Youth “Movement of the First” in specially protected areas of the Russian Federation in 2023. A research group of students, who had previously successfully implemented the testing of techniques in the Stavropol Territory, conducted geoecological soil studies in the Curonian Spit National Park, laying a geochemical transect from the Curonian Lagoon to the Baltic Sea coast. The data obtained made it possible to clarify the current geoecological state of some types of soils common in the territory of the Curonian Spit National Park, as well as to identify criteria for the physico-chemical state of soils related to modern anthropogenic impact. In general, the values of the majority of the studied parameters indicate the ecological well-being of the research area, which confirms the effectiveness of the implemented measures aimed at its conservation.
