We embark on an exploration that not only reveals the hidden layers of our planet’s story but also highlights the tangible implications for industries and decision-making. Prepare to be captivated by the fusion of science, technology, and practicality as we navigate the terrain of “Geospatial Data Analysis: Unveiling Geological Trends using Statistical Methods.”

Geospatial Data: The Foundation

Geospatial data encompasses a wide range of information tied to specific geographic locations. This data includes terrain elevation, land cover, mineral deposits, fault lines, and more. The advent of advanced technologies like Geographic Information Systems (GIS) and remote sensing has enabled the collection of vast amounts of geospatial data, providing researchers with a wealth of information about the Earth’s features and processes. However, making sense of this data requires more than just visualization—it demands insightful analysis and interpretation.

Detecting Spatial Patterns and Clusters

One of the primary objectives of geospatial data analysis is to identify spatial patterns and clusters. Statistical techniques such as spatial autocorrelation and cluster analysis play a pivotal role in achieving this goal. Spatial autocorrelation assesses the degree of similarity between data values at different locations. By calculating indices like Moran’s I, researchers can determine if nearby locations tend to have similar or dissimilar values, which can reveal underlying geological trends or anomalies.

Cluster analysis, on the other hand, groups nearby data points with similar characteristics into clusters. This can be immensely valuable in identifying geological formations or anomalies that might have otherwise gone unnoticed. For instance, mineral deposits or volcanic activity could be identified through clusters formed by specific data attributes.

Terrain Analysis and Elevation Modeling

Elevation data is crucial for understanding geological features such as mountains, valleys, and plateaus. Geostatistical techniques, including kriging and inverse distance weighting, are often employed to create elevation models that provide a comprehensive view of the Earth’s surface. These models not only help in visualizing terrain but also assist in identifying subsurface geological structures.

Furthermore, elevation models enable the identification of geological trends such as the gradual erosion of landscapes or the uplifting of mountain ranges over time. By analyzing elevation changes, researchers can gain insights into the dynamic geological processes shaping the Earth’s surface.

Predictive Modeling for Geological Events

Geospatial data analysis combined with statistical modeling has proven to be a powerful tool for predicting geological events. For instance, researchers can use historical earthquake data, coupled with geospatial variables like fault lines and tectonic plate movements, to develop predictive models for earthquake occurrences. These models aid in assessing seismic risks in different regions, contributing to disaster preparedness and mitigation efforts.

Similarly, predictive modeling can be applied to other geological phenomena, such as landslides and volcanic eruptions. By analyzing relevant geospatial data and employing statistical algorithms, researchers can create models that forecast the likelihood of these events, offering valuable insights for land-use planning and risk assessment.

Spatial Interpolation for Resource Estimation

Geological resources, such as mineral deposits and groundwater, are often distributed unevenly across the Earth’s surface. Spatial interpolation techniques, including ordinary kriging and co-kriging, help estimate resource quantities at unsampled locations based on data from nearby sites. This is particularly useful in mineral exploration and groundwater management.

By incorporating geospatial data and utilizing statistical interpolation methods, geologists can create resource distribution maps that guide exploration efforts. This not only saves time and resources but also ensures efficient utilization of geological assets.

Conclusion

Geospatial data analysis has transformed the way we perceive and study the Earth’s geological features. Statistical methods provide the analytical backbone that enables researchers to uncover hidden trends, patterns, and relationships within geospatial data. From predicting geological events to estimating resource distributions, statistical analysis empowers geologists to make informed decisions and gain deeper insights into the dynamic processes that have shaped our planet over millions of years. As technology continues to advance, geospatial data analysis will undoubtedly play an even more crucial role in advancing our understanding of Earth’s geological wonders.

Iron ore mining in the U.S. is done open and closed, because the depth of its occurrence varies. It varies from 10 to 500 meters. The largest iron ore deposit in the world, the Hull-Rust-Mahoning Open Pit Iron Mine, is also located in this area. Up to 8.5 million tons of pure raw materials are mined here annually. It is even on the register of National Historic Landmarks and has been in operation since 1893.

Uranium Ores

The Colorado Plateau is one of the largest deposits of uranium-vanadium ores. These metals are now very important to the steel industry, which has increased the intensity of metal mining in the United States. There are more than 2,000 deposits, some of which were discovered as early as 1898. The largest and most important for industrial production of ferrous metals are considered:

• Mount Taylor;
• Ambrosia Lake;
• Monument Valley;
• Jurvan;
• North Alicka;
• Mi Vida;
• White Canyon.

Ore reserves in the U.S. in the Colorado Plateau are estimated at 70 thousand tons, according to geological exploration, its potential is much higher. The amount of projected resources is estimated at 1 million tons. The ore here is represented by the minerals carnotite and tyamunite, containing up to 5% uranium.

Deposits on the Colorado Plateau provide 88% of the uranium ores from U.S. production. It can be considered unique because of the purity and quality of the raw material.

Copper

The United States produces 12.7% of the world’s copper resources. The largest amount of this raw material is produced in the state of Arizona. The main copper producing areas are considered to be Jerome, Aho, Bisbee, Globe-Miami, and White Mesa. A huge role in the U.S. non-ferrous metallurgy is played by the Morenci deposit, whose reserves are estimated at 832 million tons.

The most famous in the world is the Bingham Canyon deposit, with a resource potential of 637 million tons. But after a massive landslide in 2013, it halted operations due to huge destruction and environmental problems. It is also noteworthy that here, during the processing of raw materials, palladium was released (150 – 200 kg per year). This is a very rare metal, which is highly valued in the metals industry.

Gold compounds are also mined at copper deposits in America. They are formed by enriching the ore in the mills, but have industrial value. The bulk of the copper is mined at 17 mines in 5 states. They provide 99% of the country’s copper production. The U.S. is the 5th largest producer of this base metal in the world.

Gold

Although gold is also produced in copper mines, there are individual precious metal deposits in the country. The United States is one of the three leading nations in its production. The first deposits were discovered back in 1779 in Alaska. The largest deposits are in Nevada. The areas of industrial value are:

• Carlin;
• The gray-brown mine;
• Gold Mine;
• Gold Fleece Mine;
• Robinson.

Tourists also mine legally in the country. There are small loose gold deposits in California and Alaska that have no industrial value. But they attract miners who try to get rich or have fun with their valuable finds. There used to be even gold rush phenomena in the area.

The Precious Stones

Most emeralds have been found in North Carolina. Sapphires are mined in the state of Montana. Large quantities of beryls, topaz, moonstone, and aquamarines have also been found. In Arizona, gems have been mined for over 1000 years. The very first was turquoise, a blue-green stone. It became the world center for the production of this high quality mineral. It also received state significance in 1974. There are also large quantities of amethysts found in Arizona, in the Four Peaks mine.

Arizona has a rare type of gemstone called ant garnets. They are dark red, small-sized stones mined by ants. They haul them into the anthills along with building materials.

The state of Oregon is famous for Oregon sun stones. These are a rare type of clear opal that is bright yellow in color. Deposits in the United States of America for these stones are considered unique and are listed as natural treasures. It is formed due to the high content of copper in quartzite. Because of this, when exposed to direct sunlight, it reflects flashes of light, making the stone unique. California’s mineral potential is somewhat lower. Tourmalines and ornamental stones (jasper, benitoite, opal) are mined here the most.

Utah has distinguished itself by being the only place in the world where the Tiffany’s stone, or “purple passion,” can be found. It has a variegated pink and purple coloring, is easy to work with, and is excellent for creating jewelry. The most important stone in Arkansas is known as “rock crystal” or quartzite. Its purity attracts attention, which is why quartzite from U.S. deposits is in demand all over the world. Nevada is known for obsidian, a black volcanic glass.

Hydrocarbon minerals

Extraction of oil resources on the territory of the country began as far back as 300 years ago. Most of the hydrocarbon deposits are located in Texas, Alaska and California. Light and shale oil are widespread in America. The oldest fields in the U.S. are Midway Set (1894), East Texas (1930) and the Bakken Formation (1953). The first is located in the state of California and its reserves are estimated at 410 million tons of oil. Each year the Midway Set provides the country with 72 million tons of high quality hydrocarbons.

The Bakken formation is one of the largest sources of fuels in the United States. It is a source of light oil – containing minimal impurities. It uses directional drilling and hydraulic fracturing, which, unlike horizontal drilling, brings large-scale production. The East Texas field is one of the largest, and the leader in terms of annual hydrocarbon production.

The fields in Alaska lead in the number of geological oil reserves. Pradahoe Bay, which was discovered in 1963, is considered the main one. Its potential is estimated at 3.1 billion tons of oil and 730 billion cubic meters of gas. Oil here has a low density (0.844), which reduces processing costs and increases the cost of raw materials.

Oil production in the U.S. is carried out not only on land but also on the sea shelves. One of the most remarkable is the Petronius platform, which provides a daily production of 3 thousand cubic meters of oil and 2 million cubic meters of gas. It is located in the Gulf of Mexico near New Orleans.

Coal

Solid fuel minerals are also plentiful in the United States. The largest basin of hard coal, the Appalachian Basin, is located here. More than 15 million tons of coal are produced annually in 300 coal fields. Coal is mined by both open-pit and closed-pit methods. The type of production depends on the depth of the raw material. The advantage of this coal basin is the shallow bedding of the rock, which greatly reduces the cost of mining.

Hard coal and anthracite are also mined in Illinois, in the basin of the same name. The reserves of raw materials are estimated at 365 billion tons, but only 35 are commercial. The deposits of this basin are developed only by open-pit and cut-and-fill method, because the depth of occurrence of the rock does not exceed 300 meters. It brings the country 150 – 160 million tons of hard coal per year.

Lignite is mined in the western and southern United States:

• Montana,
• Wyoming,
• Illinois,
• Kentucky,
• West Virginia,
• Utah, Arizona,
• Louisiana.

Reserves of this natural resource in the country are estimated at 128 billion tons. New deposits in Alaska are now being explored, but their size is far inferior to the already discovered largest basins in America. Despite this, geologists predict a major find in the near future.

One consequence of the steady rise in the Earth’s temperature in recent years is the steady rise in sea level. In the 20th century alone, the average global sea level has risen by 17 centimeters. The main reason for this is the melting of glaciers, both in the largest ice sheets: the Antarctic and Greenland – and smaller mountain glaciers and ice formations on the water surface. Because of this, by 2100, the average sea level may rise by as much as 15 centimeters to 2 meters. However, due to the rotation of the Earth and uneven distribution of gravity sea level is also rising unevenly. In this case, reliable ways to predict how the local sea level in specific cities located on the coasts of different continents, to date has not been proposed.

American climatologists from NASA led by Eric Larour (Eric Larour) have decided to study the sensitivity of port cities around the Earth to the melting of specific areas of ice sheets and other ice formations. To do this, the authors of the work proposed a method based on a joint computer simulation of the circulation of the atmosphere and water in the world’s oceans, taking into account the rotation of the earth and the uneven distribution of gravity. These data were used by scientists for a mathematical model that links local sea level rise with local changes in the thickness of the glacier. The proposed algorithm allowed to take into account not only the contribution from melting glacier, but also the processes occurring as a result of warming and melting in the ocean: water expansion and changes in the directions of ocean currents.

The areas of the Greenland ice sheet whose melting would cause the greatest sea level rise in the nine major port cities on Earth

In total, the authors of the work evaluated the sensitivity to melting of the various glaciers of sea level in 293 port cities. It turned out, for example, that water levels in London are most affected by melting of the western part of the Greenland Ice Sheet, and in New York – by melting glaciers in its northeastern part. In this case, each year the sea level in New York should rise by a quarter of a centimeter, and in two hundred years, as a result of melting glaciers, it will rise by about half a meter.

According to scientists, their proposed model can be easily changed later, taking into account future climate changes.

It is worth noting that the assessment of sea level rise as a result of melting glaciers is important not only for large cities located on the coasts, but also for less populated areas, where important objects for mankind are located. For example, after the abnormally warm year of 2016, it was the melting of the permafrost that led to a small flood in the World Seed Vault located on Svalbard Island.

Despite these protections, the World Health Organization estimates that 23 percent of all deaths are due to “environmental risks” such as air pollution, water contamination and chemical exposure.

Such statistics are the reason that the UN Human Rights Council recently passed a resolution reaffirming states’ obligations to protect human rights, including by taking stronger measures to address environmental problems.

Here are some of the ways in which a threatened planet threatens the human right to health.

Destruction of wildlife contributes to zoonoses

Land alteration due to construction of homes, farms, and industries has brought humans into close contact with wildlife, setting the stage for the transfer of pathogens from wild animals to humans.

An estimated 60 percent of human infections are of animal origin. There are many other viruses ready to transfer from animals to humans. According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, “About 1.7 million unidentified viruses of the type known to infect humans still exist in mammals and waterfowl. Any one of these could be the next ‘disease X’ with more destructive and deadly potential than COVID-19.”

Air pollution reduces health quality and shortens life expectancy

Nine out of ten people in the world breathe polluted air, which harms human health and shortens life expectancy. About 7 million people die each year from air pollution-related diseases and infections, more than five times the number of people killed in traffic accidents.

Exposure to pollutants can also affect the brain, causing developmental delays, behavioral problems and even reduced IQ in children. In older people, pollutants have been linked to Alzheimer’s and Parkinson’s disease.

Reduced biodiversity reduces the nutritional value of food

In the last 50 years alone, the diet of people around the world has become 37 percent similar: just 12 crops and 5 animal species provide 75 percent of the world’s energy consumption. Today, nearly one in three people suffer from some form of malnutrition, and a significant portion of the world’s population suffers from nutrition-related diseases such as heart disease, diabetes, and cancer.

Reducing biodiversity also reduces the effect and effectiveness of drugs

Natural products make up the majority of existing pharmaceuticals and play the most important role in treating cancer. However, an estimated 15,000 species of medicinal plants are in danger of extinction, and the Earth loses at least one life-saving medicine every two years.

Sources of air pollution

All kinds of substances pollute the air: gaseous, solid and liquid, if they are contained in quantities exceeding their average content. Air pollution is divided into dust and gas pollution. The World Health Organization defines polluted air as such if its chemical composition can adversely affect human, plant and animal health as well as other elements of the environment (water, soil). Air pollution is the most dangerous of all types of pollution because it is mobile and can contaminate virtually all components of the environment over large areas.

The main sources of air pollution are:

• Industrialization and growing population,
• energy industry,
• transportation industry,
• natural sources.

The growing demand for energy has made the burning of hydrocarbons the main source of anthropogenic air pollution.

What is air pollution?

The most dangerous air pollutants are:

• sulfur dioxide (SO2),
• nitrogen oxides (NxOy),
• coal dust (X2),
• volatile organic compounds (benzapyrene)
• carbon monoxide (CO)
• carbon dioxide (CO2),
• tropospheric ozone (O3),
• lead (Pb),
• suspended dust.

Anthropogenic sources of air pollution include:

• low-altitude emissions,
• chemical fuel conversion,
• extraction and transportation of raw materials,
• chemical industry,
• processing industry,
• metallurgical industry,
• cement production,
• landfills for raw materials and waste,
• motorization.

Natural sources of air pollution:

• volcanic eruptions,
• chemical weathering of rocks,
• forest and prairie fires,
• lightning,
• cosmic dust,
• biological processes.

Contaminated air is absorbed by people mainly during breathing. It contributes to respiratory diseases, allergies, and reproductive disorders. In the human household, air pollution causes corrosion of metals and building materials. It also negatively affects plant life by disrupting photosynthesis, transpiration, and respiration. Contaminated air also degrades water and soil. Globally, air pollution affects climate change. Air pollution also increases the acidity of drinking water. It causes an increase in lead, copper, zinc, aluminum, and even cadmium in the water that comes into our apartments. Water with increased acidity destroys plumbing systems by leaching various toxic substances from them.

There are three main types of emission sources:

Point sources – these are mostly large industrial plants that emit dust, sulfur dioxide, nitrogen oxide, carbon monoxide, and heavy metals; area (dispersed) – these are household boilers and furnaces, local boilers, small industrial enterprises, emitting mainly dust and sulfur dioxide; linear – these are polluting sources that have a large extent. Responsible for emissions of nitrogen oxides, carbon monoxides, aromatic hydrocarbons, heavy metals (primarily lead from ethyl, now platinum, palladium and rhodium from automotive catalysts).

Consequences of air pollution include:

Acid rain is precipitation with a low pH. They contain sulfuric acid, formed in an atmosphere contaminated with sulfur oxides from the burning of sulfated coal, and nitric acid, formed from nitrogen oxides. According to some information, acid rain increases infant mortality and the risk of lung disease, as well as acidifying rivers and lakes, destroying flora and fauna, degrading soils, and destroying monuments and architecture.

Smog – polluted air containing a high concentration of dust and toxic gases, the source of which are mainly cars and industrial plants.

Stink (bad smells) – the result of pollutants in the air, which irritate the olfactory receptors. Most often the stench is a mixture of a large number of different compounds present in very small quantities. The impact of unpleasant smells on human health is usually psychosomatic. Solving the problem of air pollution associated with unpleasant odors requires the use of special analytical methods (sensory analysis, olfactometer).

Ozone holes – reduction of ozone (O3) content at an altitude of 15-20 km. The rate of decrease is about 3% per year. Of greatest importance in this process are chlorofluorocarbons (freons), of which the released chlorine (under the influence of ultraviolet radiation) attacks ozone molecules, resulting in the release of oxygen (O2) and chlorine(II) oxide (ClO). The rate of global decrease in stratospheric ozone levels due to human activities (excluding Antarctica), estimated from satellite studies, is 0.4-0.8% per year in the northern temperate latitudes and less than 0.2% in the tropics. The ozone layer is a natural filter that protects living organisms from harmful ultraviolet radiation. In 1995, the Nobel Prize in Chemistry was awarded for research into the effects of freons on atmospheric ozone, and for research into the formation and reactions of atmospheric ozone.

The greenhouse effect is a phenomenon occurring in the planet’s atmosphere that causes the temperature of the planet, including the Earth, to rise. The effect is caused by atmospheric gases called greenhouse gases, which limit heat radiation from the Earth’s surface and lower atmosphere to space.

Air pollution caused by cars is responsible for about 1/4 of the deaths in major cities.

Pollution of soils is associated with atmospheric and water pollution. Various solid and liquid wastes of industrial production, agriculture and municipal and domestic enterprises get into the soil. The main sources of pollution are houses and public utility companies, industrial enterprises, agriculture, transport.

Housing and communal economy

The main pollutants of soil are household waste, food waste, construction waste, waste heating systems, household items that have fallen into disrepair, garbage of public institutions (hospitals, canteens, hotels, stores).

All of this is collected and taken to municipal and local landfills, which occupy large areas of land and are sources of air and groundwater pollution by toxic substances. At present, the destruction of housing and communal waste is done by industrial processing of garbage at special factories.

Industrial enterprises

Solid and liquid industrial waste constantly contains some or other substances that can have a toxic effect on the soil, living organisms and their communities. For example, metallurgical waste contains salts of non-ferrous and heavy metals. The machine-building industry discharges cyanide, arsenic and beryllium compounds into the environment. Benzene and phenol wastes are produced in the production of plastics and man-made fibers. Waste from the pulp and paper industry, provide phenols, methanol, turpentine.

The main pathway of heavy metals into the soil is atmospheric. The greatest concentration in atmospheric emissions of enterprises have such metals as cadmium, mercury, lead, zinc, copper, nickel.

Agriculture

The main pollutants of the soil in this industry are fertilizers, pesticides used to protect plants from pests, diseases, weeds. Millions of tons of nutrients (nitrogen, potassium, phosphorus, magnesium, calcium, etc.) are removed from the soil each year with the harvest, which must be compensated. Therefore, the application of organic and mineral fertilizers – the most important means of restoring soil fertility. The need for pesticides in agriculture is explained by the fact that without them the crop yield drops sharply and is only 20-40% of what could have been obtained with their use. However, we should know that a large number of pesticides are toxic not only to pests of cultivated plants, but also to animals and humans. Unregulated use of pesticides leads to soil contamination due to the disruption of the cycle of substances in it. The peculiarity of these substances is that they remain stable in the soil for a long time, which leads to their accumulation in the harvest of crops.

The use of fertilizers in agriculture also causes a number of environmental problems associated with soil contamination by inorganic and organic chemicals. The accumulation of cadmium in the soil, which is naturally found in soil and water, as well as in plant tissues, poses a great danger to humans.

Organic fertilizers are often a source of biological soil contamination. Together with manure, pathogenic bacteria, helminth eggs and other harmful organisms enter it, which can enter the human body through food.

Transportation

Developed transport network, its progress is accompanied by negative consequences – negative impact on the environment. Environmental damage from the operation of motor vehicles is caused by toxic emissions. Thus, it has been established that every year motor vehicles emit into the atmosphere more than 12 million tons of various pollutants: carbon monoxide, nitrogen oxides, sulfur, soot and others. Most of these emissions are deposited on the soil, changing its basic natural parameters.

As the environmental problems facing modern society intensify, the demand for society faces today, the demand for of environmental statistics has increased. The recognition that the well-being of humankind depends on the state of the environment has led to increased attention to environmental and sustainability issues that require decisions and actions. To implement these measures, the regular production of high-quality environmental statistics that will support evidence-based policy development to support data-driven policy decisions so that environmental policy issues can be identified and objectively quantified is of paramount importance.

Environmental statistics reflect basic information about the state of the environment and of its most important changes occurring in space and over time. They contribute to the quality of assessment through the use of a quantitative method to provide more effective, timely, and internationally consistent analysis. Environmental statistics are needed to conduct environmental assessments, produce environmental reports and develop environmental handbooks, environmental indicators and sustainable development indicators, and to promote environmental and economic accounting.

Member States of the United Nations have focused on this area of concern during the Rio+20 Conference in June 2012. The outcome document, “The Future We Want,” contains numerous references to the work of the United Nations Statistics Division (UNSD) in this area. This document repeatedly mentions the importance of data availability, particularly environmental data, as well as relevant information and indicators. The Environmental Statistics Development Framework (ESDP 2013), which includes a set of key environmental statistics indicators, serves as an adequate tool to address these information needs as they relate to the environmental dimension of sustainable development. At the forty-fourth Statistical Commission at its forty-fourth session, the SDGs were recognized a useful tool to adequately respond to the increasing demand for information in the follow-up to Rio+20 and the post-2015 development agenda (including the Sustainable Development Goals).

The problem of producing statistical data on the environment

Environmental statistics cover a broad set of data and is interdisciplinary in nature. The data come from a wide variety of sources and are collected Data are collected using an equally diverse and multiple methodologies. Specific statistics and methodologies are equally needed to effectively produce
environmental statistics equally requires specific statistical and environmental expertise, scientific knowledge, institutional capacity, and sufficient resources. Many countries still need significant technical assistance and capacity building in this area. Thus, the development of environmental statistics requires an appropriate framework to guide, coordinate and organize the data collection process at all levels
