Cryoconite holes are structures characteristic of the glacierised ablation areas, formed from dark sediment deposition which melt the glacier ice leading to their cylindrical structure formation. The present study focuses on an unstudied blue ice area of East Antarctica over the Hells Gate Ice Shelf ...

Cryoconite holes are the most active and diverse microbial habitats on glacier and ice-sheet surfaces. In this article the authors demonstrate that the shape of cryoconite holes varies depending on ice-surface topography and that this has implications for the carbon cycling regime within. Net ...
Nordenskjöld, who, during his first expedition to the Greenland Ice Cap, observed numerous water-filled cylindrical holes sunk into the ice. The bottom of these holes are covered with dust a few millimetres thick. This powdery dust he called “cryoconite” from Greek “kruos” (ice) and ...
Define cryoconite. cryoconite synonyms, cryoconite pronunciation, cryoconite translation, English dictionary definition of cryoconite. pl n a dark powder found at the bottom of glacier holes, formerly thought to be cosmic in origin but now widely regarde
truncated food web36. They can be hydrologically connected, where melt water moves through the top layer of ice, however the sedimentary material itself, where the vast majority of microbial activity takes place, remains on the ice for years to decades37. Cryoconite holes may therefore be ...
higher content of organic carbon in soils (up to 7.82%) in comparison with cryoconite (max. 1.63%) due to presence of vegetation, however, the basal respiration values in some cases were similar between сryoconite and soils, indicating high rates of microbial activity in a cryoconite holes....
The terminal part of the Morteratsch glacier from a photogrammetric reconstruction (September 2016). Cryoconite samples collection sites are indicated by dots (black 2015; white 2016), the black square is used for moraine sediment collection site). On the right some cryoconite holes sampled to the...
Energy sources governing the growth of cryoconite holes have been investigated by monitoring the meteorological balance at the surface of the Manatee Glacier, British Columbia, the dimensions of 125 holes, and the thermal conditions within them. Cryoconite holes are shown to be rough indicators of ...
Cryoconite holes, usually considered to be simple ecosystems, seem to be complex habitats where hidden spatial heterogeneity may affect abundance and diversity of organisms.doi:10.1007/s10452-019-09681-9Zawierucha, KrzysztofBuda, JakubFontaneto, Diego...
