“…In the case of the World Ocean, three latitudinal zones are separated: the equatorial zone Ξ O 1 = {( ϕ , λ ): ϕ ∈[0° N, 30° N]∪[0° S, 30° S]; 0° ≤ λ ≤ 360°}, temperate latitudes Ξ O 2 = {( ϕ , λ ): ϕ ∈[30° N, 60° N]∪[30°S, 60°S]; 0° ≤ λ ≤ 360°} and Arctic and Antarctic zone Ξ O 3 = {( ϕ , λ ): ϕ ∈[60° N, 90° N]∪[60° S, 90° S]; 0° ≤ λ ≤ 360°}. Pelagic Ξ O1P and upwelling Ξ O1U aquatories are selected in the Ξ O1 zone to differ in productivity and gas exchange rate on the air-water boundary [ 46 , 47 ].…”

This paper presents the results obtained from the study of the sustainable state between nature and human society on a global scale, focusing on the most critical interactions between the natural and anthropogenic processes. Apart from the conventional global models, the basic tool employed herein is the newly proposed complex model entitled “nature-society system (NSS) model”, through which a reliable modeling of the processes taking place in the global climate-nature-society system (CNSS) is achieved. This universal tool is mainly based on the information technology that allows the adaptive conformance of the parametric and functional space of this model. The structure of this model includes the global biogeochemical cycles, the hydrological cycle, the demographic processes and a simple climate model. In this model, the survivability indicator is used as a criterion for the survival of humanity, which defines a trend in the dynamics of the total biomass of the biosphere, taking into account the trends of the biocomplexity dynamics of the land and hydrosphere ecosystems. It should be stressed that there are no other complex global models comparable to those of the CNSS model developed here. The potential of this global model is demonstrated through specific examples in which the classification of the terrestrial ecosystem is accomplished by separating 30 soil-plant formations for geographic pixels 4° × 5°. In addition, humanity is considered to be represented by three groups of economic development status (high, transition, developing) and the World Ocean is parameterized by three latitude zones (low, middle, high). The modelling results obtained show the dynamics of the CNSS at the beginning of the 23rd century, according to which the world population can reach the level of 14 billion without the occurrence of major negative impacts.

“…Based on this, they propose new approaches to the evaluation of anthropogenic processes. In [2], it is stated that problems related to the greenhouse effect are solved in many scientific works. Their contribution presents one of the possible approaches to solving this problem, which is based on the creation of a new model of combined biogeochemical cycles of carbon and methane.…”

Accurate navigation systems allow us to optimize the trajectory of flying objects and thus solve environmental problems in aviation and their impact on public health. In this paper, we present one of the methods of assessment of accuracy and resistance to interference of distance-measuring equipment (DME). By using computer technology, the method enables us to determine the potential but also the real error measuring the distance of the flying object from DME. The credibility of the respective results of the solution on the task of DME optimal rangefinder synthesis depends on the accuracy of the previous data used, i.e., mathematical models of the respective flying objects flight dynamics, useful signals, and their parameters and interference. DME systems have an impact on air transport safety, and therefore the impact of interference on their operation must be investigated.

“…During the next year, the oceans absorb 10% of the emitted carbon and during the next century only 1.3% of the increased atmospheric carbon has remained in the atmosphere. The system atmosphere-ocean over 100 years goes to the carbon balance and carbon content in the deep ocean increase by 9% (Krapivin et al, 2017a). Realized impact on the coniferous forests is reflected in the humus layer dynamics, that over 30 years, has lost 4% of its reserves.…”

“…Figure 4 demonstrates the general structure of GIMS as the aggregate approaches, instruments, and methods for the processing of structured and unstructured data characterized by big volumes and significant variety. GIMS allows the combined use of different approaches to the processing of big data fluxes that primarily solve a new decision-making process to optimize these fluxes at the expense of effective monitoring alternatives and data processing tools (Krapivin, Varotsos, & Soldatov, 2017a, 2017b.

In this paper, the geoecological information-modeling system (GIMS) is described as possible improvement of the Big Data approach. The main GIMS function is the use of algorithms and models that capture the fundamental processes controlling the evolution of the climate-nature-society (CNSS) system. The GIMS structure includes 24 blocks that realize a series of models and algorithms for global big data processing and analysis. The CNSS global model is the basic block of the GIMS. The operational tools of GIMS are demonstrated by examining several scenarios associated with the reconstruction of forest areas. It is shown that significant impacts on forests can lead to global climate variations on a large scale.
