Today the school is digitally extended beyond the school building to the universe; a school is a ship, a workshop, a factory, a laboratory, a theatre, a museum, a forest and an ocean. The purpose of the school and the teacher is to give the student motivation for active life and learning, help him organize his activities and cooperate with peers and significant adults, ensure the preservation and promotion of health, equalize the opportunities for quality education for all, give chances for a decent future for children with disabilities health and their families. Using and developing all the abilities and possibilities of his extended personality the teacher learns together with the students, gives feedback and, most importantly, motivates and captivates the students. We must not catch up but get ahead of events.

The purpose of the study is to develop a methodology for integrated geoecological zoning of the northern plain territories of the Russian Federation based on digital elevation models. Geomorphometric elevation parameters have been calculated to take into account: a) exogenous factors; b) endogenous factors – the coefficient of discrete- ness and energy intensity, fault density and the function of crushing the Earth’s crust. Such an integrated approach has no analogues and allows taking into account the impact on the state of the environment of exogenous and endogenous, climatic and other natural factors at the global, regional and local levels. As a result, a methodology for integrated geoecological zoning of the northern plain territories of the Russian Federation was developed on the basis of modern digital elevation models using GIS technologies and maps of geoecological zoning.

The characteristics of the development of anthropogenically induced processes in the land waters of the Arctic basin, such as eutrophication, acidification and toxic pollution in a changing climate, are characterized. The main changes in ecosystems and periods of occurrence of the most dangerous situations are shown. The criteria for diagnosing adverse processes and the need to tighten water quality standards for the waters of the Arctic regions are substantiated.

This paper provides a brief overview of the state of research on the Global Ocean Conveyor Belt (GOCB) as an element of the Global Ocean Circulation linking the thermocline and the abyssal. In particular, it is noted that the existence of GOCB cannot be due only to the action of thermohaline factors. In addition to them, a wind effect on the Ocean is also necessary. Moreover, the area of such impact, which determines the very configuration of the GOCB, is the Southern Ocean. In addition, for the very existence of the GOCB in its current form, the configuration of the continents of the current geological epoch is of fundamental importance.

The United Nations Decade of Ocean Science for Sustainable Development (2021–2030) was proclaimed by the UN General Assembly in 2017 on the initiative of the Intergovernmental Oceanographic Commission of UNESCO and entered the implementation phase from January 2021. The main watchword of the Decade is “The Science We Need for the Ocean We Want”. It is based on seven socially significant outcomes. To achieve them, ten priority challenges have been identified. These challenges are divided into three groups: Knowledge and Solutions Challenges, Essen- tial Infrastructure Challenges and Foundational Challenges. Although the Decade Implementation Plan considers Ocean Sciences in its broadest sense, including the nature sciences and social sciences and humanities, local and indigenous knowledge, science-policy and science-innovation interactions, and technology and infrastructure etc., basic oceanographic research are of paramount importance for understanding and achieving virtually all seven Decade Outcomes.

The work summarizes the results of investigations carried out in three directions (blocks). Block 1. Terrestrial ecosystems in areas of intensive nature management are investigated. Climatic changes and anthropogenic impact result in transformation of landscapes with disturbed or completely destroyed vegetation cover. In freshwater ecosystems cardinal changes in the structural and functional organization from the multifac- torial anthropogenic load against the background of a warming climate were revealed. We obtained unique data on the long-term dynamics of biodiversity in aquatic ecosystems. Block 2. Enrichment tailings properties were studied, the influence of the dusting season duration and humidity changes on the gross dust emission was assessed; interaction of tailings with soil waters was studied. The potential ecological danger of tailings mineral particles getting into the soil was shown. The losses of non-ferrous metals during the period of waste storage under different climate change scenarios were estimated. Block 3. People’s perceptions of climate change and its social consequences have been studied. The problem of climate change clearly correlates with ecological problems. The impact of the COVID-19 pandemic on the Arctic in the context of climate change was studied. The pandemic highlighted the unsustainability of the rotational method of resource development, with rotational camps becoming focal points of epidemiological hazards.

Today there are different understandings of what is considered part of a digital platform, what is on it and what is available through it. A digital integrated implementation of the following functions is required, regardless of how we define their relationship with the platform: support for group communication with the ability to record the process; accounting for the roles of the student, teacher, administrator, parent; automatic generation of digital journals and report cards; formation of the history of individual work and recording of educational events of the student, teacher, class; including it in the big data of education; designing an individual path for students to achieve educational goals with a choice of those posted on the platform; selection and implementation of tasks offered by the teacher; placement the goals, assignments, feedback and assessment tools, other learning materials; accommodating student learning requests and suggestions from teachers, organizations, and educational programs that go beyond the boundaries of one school; recording learning outcomes; displaying and forecasting on the basis of big data of the educational process with varying level of detail.

Based on the analysis of data from long-term radioecological observations in the Barents Sea, the main migration flows of 137Cs and 90Sr in its ecosystem have been reconstructed. In the current (2010–2019) balance of technogenic radioactivity, the transboundary transfer of radioisotopes from the Norwegian Sea accounts for more than 90% of the total intake. Most of the incoming radionuclides are removed from the Barents Sea through its northern and northeastern borders in the process of water exchange. A significant decrease in the concentrations of radionu- clides in the components of the environment and biota in the “post-nuclear era” is shown. The content of 137Cs and 90Sr in the food web of the marine ecosystem was estimated in comparison with the reserve of their activity in water and bottom sediments. The biotas accumulate no more than 0.01% of the total isotope content in the ecosystem.

The long-term data sets of the annual and seasonal water flows and the major ions fluxes of the Northern Dvina River at the village of Ust-Pinega and Pechora River at the village of Ust-Tsilma were analyzed. Long-term phases of increased and decreased values of water runoff were identified, the duration of which ranged from 9 to 50 years, and their main characteristics were determined. The sequence and boundaries of the change in the contrasting phases of the annual water flow, the snowmelt flood flow and the summer-autumn flow on the Northern Dvina River and the annual water flow and snowmelt flood flow on the Pechora River practically coincided. The difference between the average annual and seasonal water flow in the phases of its increased and decreased values ranged from 11 to 41%, and the ion fluxes were in the range of 5–36%. The ion flux of contrast phases, as a rule, differs less than the water flow. This is due to the inverse nature of the dependence of the concentration of ions on the daily water discharges, because of which a kind of negative feedback is formed, stabilizing the intensity of chemical denudation in the wa- tersheds of these rivers and the flux of the main ions into the seas, even with noticeable fluctuations in water flow. Keywords: the Northern Dvina River, the Pechora River, water flow, ion flux, long-term phases of changes, cumulative deviation curves.
