IOP Conference Series: Earth and Environmental Science. 2021. Vol. 834. No. 1. Article 012003.

The study was based, firstly, on the diverse data collected during field work in 2018 – 2020 in the eastern part of the Terek River delta and long-term hydrological monitoring data on the Roshydromet gauges. Secondly, on a profound comparative analysis of multi-temporal cartographic materials and multiple satellite images, laboratory analysis of water and sediment samples and other research groups’ field data. The performed analysis resulted in unprecedented complex and profound assessment of the contemporary hydrological, morphological and ecological state of the former Agrakhan Bay of the Caspian Sea. The drivers, dependencies and parameters of hydrological and morphological degradation were described; a multi-layer large-scale GIS was created to design multiple illustrations. The performed assessment allowed for development of measures for partial restoration of the hydrological and ecological potential of the former Agrakhan Bay.

В обзоре интеллектуальное наследие В.И. Вернадского (1863-1945) рассматривается в контексте зарубежных инвайронментальных исследований (преимущественно на материале англоязычных публикаций двух последних десятилетий). Реконструируются ключевые идейные истоки мировоззрения Вернадского: влияние В.В. Докучаева, русского космизма и концепции ноосферы П. Тейяра де Шардена. Анализируются понятия научной системы Вернадского - «живое вещество», «биосфера» и «ноосфера»; прослеживается их рецепция в современных ...

Rangeland degradation is a global environmental challenge; however, intense debate persists between equilibrium (focused on the negative effects of grazing intensity) and non-equilibrium (emphasizing livestock mobility for adapting to climate variability) theories in rangeland ecology. In recent years, an integrative theory advocating the “coexistence of equilibrium and non-equilibrium” has emerged to reconcile this debate. However, ...

Migration for higher education is one of the largest and most intense migration flows in most developed countries, and Russia is no exception. The direction of educational migration flows is determined by many factors. Among these, traditionally significant determinants of the basic gravity model include the population size of the centers participating in migration exchange ...

Взрывной рост объема данных несколько последних десятилетий ставит вопрос перехода от количества к качеству их использования, ведь не всегда они доходят до конечного пользователя и используются на региональном и локальном уровне. Данные дистанционного зондирования Земли из космоса (ДЗЗ), основанные на длинных временных сериях, и результаты их обработки уже давно стали глобальными цифровыми продуктами. Когда речь ...

This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high-frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera-M satellite. The experiment combined ground-based observations with in situ satellite measurements, enabling a comprehensive study of artificial ionospheric disturbances. During the experiment, the SURA facility transmitted ...

This study analyzes data from the ERG (Arase) satellite over a period of nearly 7 years (2017–2023). During this time, about 1,000 cases of hectometric continuum (HMC) radiation in near‐Earth space were detected, which made it possible to identify characteristic features on different time scales. On a daily scale, it was established that HMC is ...

The ERG (Arase) satellite recently discovered a non-thermal hectometric continuum with a narrowband frequency structure. The mechanism behind the generation of this type of emission in the near-Earth plasma is still unknown. This study examines the potential use of electron cyclotron harmonics instability to explain the line structure of hectometric radio emissions for the first ...

The carbon balance of an ecosystem is the difference between Gross Primary Productivity (GPP) and Ecosystem Respiration (Reco) as expressed by Net Ecosystem Exchange (NEE). While remote sensing retrievals of GPP have reached maturity, Reco estimation remains underexplored and ultimately cast bias on NEE. Here we present an end-to-end multi-scale analysis of the mechanism of ...

Legacy soil maps remain essential for national land-use planning. However, their thematic accuracy and spatial resolution are often insufficient for contemporary applications requiring reliable estimates. This study presents a digital soil-mapping approach to update legacy soil information without extensive field sampling, demonstrated for arable lands in the Republic of Tatarstan (4.5 million ha). The proposed ...

On July 29, 2025, a strong earthquake near Kamchatka (Russia) generated a tsunami that spread across the entire
Pacific Ocean. The tsunami had its strongest impact on the coast of the North Kuril Islands (Paramushir and Shumshu), causing significant destruction. During the first days after the earthquake, a field survey of tsunami traces on these islands was conducted in the area ...

An observed 20-30% increase in forest net ecosystem exchange (NEE) on partly cloudy days is often attributed to there being more uniform canopy illumination by diffuse radiation when clouds are present. However, the sky on such days is typically populated by fair-weather cumulus clouds, bringing dynamically changing shadow-to-light conditions on the order of minutes to ...
