Planting of new forests on lands that historically have not contained forests.  (EPA Glossary of Climate Change Terms)

The process of refreshing air quality to improve health and well-being. This involves enhancing air quality and circulation

See Bioreactor

A variety of charcoal produced by heating organic materials in a low oxygen environment, known as pyrolysis.  The proiciple objective of this activity is the sequestration of atmospheric carbon in the biochar, which can subsequently be used for enhancing soil fertility (A Dictionary of Climate Change and the Environment : Economics, Science, and Policy)

Gas or liquid fuel made from plant material. Includes wood, wood waste, wood liquors, peat, railroad ties, wood sludge, spent sulfite liquors, agricultural waste, straw, tires, fish oils, tall oil, sludge waste, waste alcohol, municipal solid waste, landfill gases, other waste, and ethanol blended into motor gasoline. 

storage of atmospheric carbon in vegetation, soils, woody products, and aquatic environments. For example, by encouraging the growth of plants—particularly larger plants like trees—advocates of biologic sequestration hope to help remove CO2 from the atmosphere. (USGS Frequently Asked Questions (FAQ))

The timely supply of the necessities for sustaining life where the biological entity is required to perform functions that cannot be accomplished by machines. (Biologistics for Space Systems Symposium)

Materials that are biological in origin, including organic material (both living and dead) from above and below ground, for example, trees, crops, grasses, tree litter, roots, and animals and animal waste. (EPA Glossary of Climate Change Terms)

Biological processors to remove or produce certain chemicals or a particular chemical. (NASA Thesaurus, Voulme 3, Definitions, 1988 Edition, NASA SP-7064(Vol.3)

See Closed Ecological System

The removal of carbon dioxide through biological processes, such as photosynthesis in plants and the fromation of biochar. (A Dictionary of Climate Change and the Environment : Economics, Science, and Policy)

The part of the Earth system comprising all ecosystems and living organisms, in the atmosphere, on land (terrestrial biosphere) or in the oceans (marine biosphere), including derived dead organic matter, such as litter, soil organic matter and oceanic detritus.  (EPA Glossary of Climate Change Terms)

Carbon capture and sequestration (CCS) is a set of technologies that can greatly reduce carbon dioxide emissions from new and existing coal- and gas-fired power plants, industrial processes, and other stationary sources of carbon dioxide. It is a three-step process that includes capture of carbon dioxide from power plants or industrial sources; transport of the captured and compressed carbon dioxide (usually in pipelines); and underground injection and geologic sequestration, or permanent storage, of that carbon dioxide in rock formations that contain tiny openings or pores that trap and hold the carbon dioxide. (EPA Glossary of Climate Change Terms)

All parts (reservoirs) and fluxes of carbon. The cycle is usually thought of as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels). The annual movements of carbon, the carbon exchanges between reservoirs, occur because of various chemical, physical, geological, and biological processes. The ocean contains the largest pool of carbon near the surface of the Earth, but most of that pool is not involved with rapid exchange with the atmosphere.  (EPA Glossary of Climate Change Terms)

A reservoir with the capacity to store and release carbon, such as soil, terrestrial vegetation, the ocean, and the atmosphere (McGraw-Hill Dictionary of Scientific and Technical Terms, Sixth Edition)

Terrestrial, or biologic, carbon sequestration is the process by which trees and plants absorb carbon dioxide, release the oxygen, and store the carbon. Geologic sequestration is one step in the process of carbon capture and sequestration (CCS), and involves injecting carbon dioxide deep underground where it stays permanently. (EPA Glossary of Climate Change Terms)

Systems that provide for the maintenance of life in an isolated living chamber through complete reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (NASA Thesaurus, Volume 1, Hierarchical Listing with Definitions, April 2010, NASA/SP-2010-7501/VOL1)

See Information Retrieval

A database, finding aid, or other resource used to find information (ALA Glossary of Library and Information Science, 4th Edition, 2013)

A powerful approximation technique used to solve problems in various engineering disciplines, such as the static and dynamic analysis of complex sturctures (aircraft, bridges, buildings, damsm, machines, tanks, and ships), fluid flow and diffusion problems, and heat transfer and magnetic problems, among many others.  The term finite element method (FEM) is not the preferred term in contemporary literature. (Van Nostrand's Scientific Encyclopedia, Eight Edition)

An approximation method for studying continuous physical systems, used in structural mechanics, electrical field theory and fluid mechanics; the system is broken into discrete elements interconnected at discrete node points (McGraw-Hill Dictionary of Scientific and Technical Terms, Sixth Edition)

A general term referring to publications that are published and distributed outside of the mainstream.  This encompasses materials such as technical reports, government publications, and white papers (ALA Glossary of Information Science, 4th Edition, 2013)

The process of searching, locating and retrieving data from a file or database.  Synonymous with discovery, information discovery, and retrieval (ALA Glossary of Library and Information Science, 4th Edition, 2013)

An enclosed, illuminated culture vessel designed to control biomass production through adjustment of the operating parameters. (Handbook of algal science, technology and medicine, 2020)

The process by which plants take CO₂ from the air (or bicarbonate in water) to build carbohydrates, releasing O₂ in the process. There are several pathways of photosynthesis with different responses to atmospheric CO₂ concentrations. (EPA Glossary of Climate Change Terms)

Planting of forests on lands that have previously contained forests but that have been converted to some other use. (EPA Glossary of Climate Change Terms)

A report giving details and results of a specific investigation of a scientific or technical problem (ALA Glossary of Library and Information Science, 4th Edition, 2013)
