Ishøyninger
Ishøyninger is a glaciological term used in Norwegian to describe localized elevations on the surface of an ice body, such as a glacier or an ice shelf. The concept corresponds to features commonly described in English as ice rises or hummocky surface highs and is of interest because it reflects the interaction between ice flow and underlying conditions.
Formation occurs where the ice encounters subglacial topography, bedrock highs, or variations in grounding status that
Characteristics include appearing as isolated or clustered surface elevations with rough, hummocky textures. Their size can
Distribution and study: Ishøyninger are commonly observed in polar regions with extensive ice shelves or fast-flowing
Importance: These features influence local ice dynamics, including flow velocity, crevasse patterns, and the stability and
Terminology: The Norwegian term is prevalent in Nordic glaciology; in international literature the English equivalent “ice
