The National Geothermal Data System (NGDS) is an American distributed data network that collects and provides public access to digital geothermal exploration and development information. Data includes borehole temperature measurements, geothermal gradients, active faults, and geochemical analyses.

Distributed computing is a field of computer science that studies distributed systems. A distributed system is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another. The components interact with one another in order to achieve a common goal. Three significant characteristics of distributed systems are: concurrency of components, lack of a global clock, and independent failure of components. Examples of distributed systems vary from SOA-based systems to massively multiplayer online games to peer-to-peer applications.

Geothermal energy thermal energy generated and stored in the Earth

Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials. The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. The adjective geothermal originates from the Greek roots γη (ge), meaning earth, and θερμος (thermos), meaning hot.

Borehole narrow shaft bored in the ground

A borehole is a narrow shaft bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water, other liquids or gases, as part of a geotechnical investigation, environmental site assessment, mineral exploration, temperature measurement, as a pilot hole for installing piers or underground utilities, for geothermal installations, or for underground storage of unwanted substances, e.g. in carbon capture and storage.

History

NGDS was initially funded by the United States Department of Energy Geothermal Technologies Program (awards DE-EE0001120 and DE-EE002850), as part of the American Recovery and Reinvestment Act of 2009.

United States Department of Energy Cabinet-level department of the United States government

The United States Department of Energy (DOE) is a cabinet-level department of the United States Government concerned with the United States' policies regarding energy and safety in handling nuclear material. Its responsibilities include the nation's nuclear weapons program, nuclear reactor production for the United States Navy, energy conservation, energy-related research, radioactive waste disposal, and domestic energy production. It also directs research in genomics; the Human Genome Project originated in a DOE initiative. DOE sponsors more research in the physical sciences than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The agency is administered by the United States Secretary of Energy, and its headquarters are located in Southwest Washington, D.C., on Independence Avenue in the James V. Forrestal Building, named for James Forrestal, as well as in Germantown, Maryland.

American Recovery and Reinvestment Act of 2009

The American Recovery and Reinvestment Act of 2009 (ARRA), nicknamed the Recovery Act, was a stimulus package enacted by the 111th U.S. Congress and signed into law by President Barack Obama in February 2009. Developed in response to the Great Recession, the ARRA's primary objective was to save existing jobs and create new ones as soon as possible. Other objectives were to provide temporary relief programs for those most affected by the recession and invest in infrastructure, education, health, and renewable energy.

The National Geothermal Data System makes use of the large collection of hard copy documents stored in state geological survey archives. [1] [2] These documents include maps, field notes and well logs relevant to geothermal exploration and development. Some of the information was originally gathered for use by the oil industry. [3] NGDS facilitates the digitization of this data, and ensures that data from various sources is stored in a compatible format to facilitate standardized search terms and geospatial analyses. Participating agencies maintain ownership and control of data they contribute.

In information handling, the U.S. Federal Standard 1037C defines a hard copy as a permanent reproduction, or copy, in the form of a physical object, of any media suitable for direct use by a person, of displayed or transmitted data. Examples of hard copy include teleprinter pages, continuous printed tapes, computer printouts, and radio photo prints. On the other hand, physical objects such as magnetic tapes diskettes, or non-printed punched paper tapes are not defined as hard copy by 1037C.

A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model. Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing methods, such as aerial photography and satellite imagery. Such surveys may be undertaken by state, province, or national geological survey organizations to maintain the geological inventory and advance the knowledge of geosciences for the benefit of the nation. A geological survey map typically superimposes the surveyed extent and boundaries of geological units on a topographic map, together with information at points and lines. The maps and reports created by geological survey organisations generally aim for geographic continuity and completeness in establishing the spatial patterns of near-surface rock units. The map may include cross sections to illustrate the three-dimensional interpretation. Subsurface geological and geophysical maps, providing limited coverage of deeper geology, are maintained internally by major oil companies and regulators. Some geological survey organisations have collaborated with them to include subsurface geology in their systematic surveys, for example, the Geological Atlas of the Western Canada Sedimentary Basin. Subsurface maps typically depict the three-dimensional form of geological surfaces by means of contours and cross sections. Computer-based models are increasingly used to provide more comprehensive information storage and greater flexibility of presentation. In the United States, the 50 state surveys are coordinated by the Association of American State Geologists.

Well logging, also known as borehole logging is the practice of making a detailed record of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface or on physical measurements made by instruments lowered into the hole. Some types of geophysical well logs can be done during any phase of a well's history: drilling, completing, producing, or abandoning. Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental and geotechnical studies.

Once digitized, the NGDS provides free public access to the data by means of a distributed network of online databases, and also provide the public with free and open-source software with which to search and view the data. [4] [5]

Free and open-source software software that is both free and open-source

Free and open-source software (FOSS) is software that can be classified as both free software and open-source software. That is, anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users.

Participating Agencies

NGDS primary contributors include the United States Geological Survey, Southern Methodist University, and the Association of American State Geologists.

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

Southern Methodist University Private university in Dallas, Texas, United States

Southern Methodist University is a private research university in metropolitan Dallas, Texas with its main campus located in University Park. SMU also operates satellite campuses in Plano, Texas and Taos, New Mexico.

Most agencies that contribute data to NGDS host their data on their own servers; [6] some smaller agencies submit their data to contract-designated hubs, while still owning their data. NGDS hub states include Arizona, Illinois, Kentucky, and Nevada.

Server (computing) computer to access a central resource or service on a network

In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Arizona state of the United States of America

Arizona is a state in the southwestern region of the United States. It is also part of the Western and the Mountain states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona shares the Four Corners region with Utah, Colorado, and New Mexico; its other neighboring states are Nevada and California to the west and the Mexican states of Sonora and Baja California to the south and southwest.

Illinois State of the United States of America

Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product (GDP), the sixth largest population, and the 25th largest land area of all U.S. states. Illinois is often noted as a microcosm of the entire United States. With Chicago in northeastern Illinois, small industrial cities and immense agricultural productivity in the north and center of the state, and natural resources such as coal, timber, and petroleum in the south, Illinois has a diverse economic base, and is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population. The Port of Chicago connects the state to international ports via two main routes: from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean and from the Great Lakes to the Mississippi River, via the Illinois Waterway to the Illinois River. The Mississippi River, the Ohio River, and the Wabash River form parts of the boundaries of Illinois. For decades, Chicago's O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a bellwether both in social and cultural terms and, through the 1980s, in politics.


Participating agencies also submit metadata records to a central web-accessible catalog, describing the data that has been contributed to NGDS. Both NGDS data and the NGDS catalog can be accessed by common web browsers and web applications. NGDS data can also be accessed by geographic information system software applications including ArcGIS, UDig, QGIS, and GvSIG.

Web mapping

Web mapping is the process of using the maps delivered by geographic information systems (GIS) in World Wide Web. A web map on the World Wide Web is both served and consumed, thus web mapping is more than just web cartography, it is a service by which consumers may choose what the map will show. Web GIS emphasizes geodata processing aspects more involved with design aspects such as data acquisition and server software architecture such as data storage and algorithms, than it does the end-user reports themselves.

Geothermal power in the United Kingdom

The potential for exploiting geothermal energy in the United Kingdom on a commercial basis was initially examined by the Department of Energy in the wake of the 1973 oil crisis. Several regions of the country were identified, but interest in developing them was lost as petroleum prices fell. Although the UK is not actively volcanic, a large heat resource is potentially available via shallow geothermal ground source heat pumps, shallow aquifers and deep saline aquifers in the mesozoic basins of the UK. Geothermal energy is plentiful beneath the UK, although it is not readily accessible currently except in specific locations.

Geothermal energy in the United States was first used for electric power production in 1960. The Geysers in California was developed into what is now the largest geothermal steam electrical plant in the world, at 750 megawatts. Other geothermal steam fields are known in the western United States and Alaska. Geothermally-generated electric power can be dispatchable to follow the demands of changing loads. Environmental impact of this energy source includes hydrogen sulfide emissions, corrosive or saline chemicals discharged in waste water, possible seismic effects from water injection into rock formations, wast heat and noise.

Iceland GeoSurvey (ÍSOR) is a consulting and research institute providing specialist services to the Icelandic power industry, the Icelandic government and foreign companies, in particular in the field of geothermal sciences and utilisation. It also aims to advance geoscientific knowledge of the Iceland landmass and its continental shelf by means of systematic surveying, monitoring and research. The headquarters are in Reykjavík with an affiliate in Akureyri, North Iceland.

Cultural analytics is the exploration and analysis of massive cultural data sets of visual material – both digitized visual artifacts and contemporary visual and interactive media. Taking on the challenge of how to best explore large collections of rich cultural content, cultural analytics researchers developed new methods and intuitive visual techniques which rely on high-resolution visualization and digital image processing. These methods are used to address both the existing research questions in humanities, to explore new questions, and to develop new theoretical concepts which fit the mega-scale of digital culture in the early 21st century.

Geothermal exploration

Geothermal exploration is the exploration of the subsurface in search of viable active geothermal regions with the goal of building a geothermal power plant, where hot fluids drive turbines to create electricity. Exploration methods include a broad range of disciplines including geology, geophysics, geochemistry and engineering.

The NASA Exoplanet Archive is an online astronomical exoplanet catalog and data service that collects and serves public data that support the search for and characterization of extra-solar planets (exoplanets) and their host stars. It is part of the Infrared Processing and Analysis Center and is on the campus of the California Institute of Technology (Caltech) in Pasadena, CA. The archive is funded by NASA and was launched in early December 2011 by the NASA Exoplanet Science Institute as part of NASA's Exoplanet Exploration Program. In July 2017, the archive's collection of confirmed exoplanets surpassed 3,500.

Systems geology emphasizes the nature of geology as a system – that is, as a set of interacting parts that function as a whole. The systems approach involves study of the linkages or interfaces between the component objects and processes at all levels of detail in order to gain a more comprehensive understanding of the solid Earth. A long-term objective is to provide computational support throughout the cycles of investigation, integrating observation and experiment with modeling and theory, each reinforcing the other. The overall complexity suggests that systems geology must be based on the wider emerging cyberinfrastructure, and should aim to harmonize geological information with Earth system science within the context of the e-science vision of a comprehensive global knowledge system.

Open energy system database projects employ open data methods to collect, clean, and republish energy-related datasets for open use. The resulting information is then available, given a suitable open license, for statistical analysis and for building numerical energy system models, including open energy system models. Permissive licenses like Creative Commons CC0 and CC BY are preferred, but some projects will house data made public under market transparency regulations and carrying unqualified copyright.
