Glossary A
Deutsch: Aragonit / Español: Aragonito / Português: Aragonita / Français: Aragonite / Italiano: Aragonite
Aragonite in the environment context refers to a naturally occurring crystal form of calcium carbonate (CaCO₃), essential in marine ecosystems. It is one of the two main crystal structures—along with calcite—that marine organisms use to build shells and skeletons. Aragonite plays a critical role in ocean chemistry, carbonate cycling, and the health of coral reefs and shell-forming species.
Deutsch: Arktis / Español: Ártico / Português: Ártico / Français: Arctique / Italiano: Artico
In the environmental context, the Arctic refers to the northernmost region of the Earth, characterized by its cold climate, ice-covered seas, distinct ecosystems, and unique biodiversity. This region includes the Arctic Ocean, parts of Canada, Greenland, Russia, the United States (Alaska), Iceland, Norway, Sweden, and Finland. The Arctic plays a crucial role in the global climate system and is experiencing rapid environmental changes due to global warming, with significant implications for its ice cover, ecosystems, and Indigenous communities.
Deutsch: ArcView-Softwareerweiterung / Español: Extensión de software ArcView / Português: Extensão de software ArcView / Français: Extension du logiciel ArcView / Italiano: Estensione software ArcView
ArcView software extension refers to add-ons or plugins designed to enhance the functionality of ArcView, which is a widely used geographic information system (GIS) software developed by Esri. These extensions provide specialized tools and features that allow users to perform advanced spatial Analysis, data visualization, and environmental modeling.
Deutsch: Fläche / Español: Area / Português: Area / Français: Aire / Italiano: Area
Area is a quantity that expresses the extent of a two-dimensional surface or shape, or planar lamina, in the plane. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).
