cryoconite in British English (kraɪˈɒkəˌnaɪt) plural nouna dark powder found at the bottom of glacier holes, formerly thought to be cosmic in origin but now widely regarded to be terrestrial Examples of 'cryoconite' in a sentencecryoconite Finally, we find cyanobacteria and algae in the cryoconite.Cryoconite holes are considered the most biologically active environments on glaciers.This study examines both supraglacial melt streams and cryoconite holes.Microorganisms on glaciers form consortia – cryoconite granules (cryoconites).Cryoconite holes are the most active and diverse microbial habitats on glacier and ice-sheet surfaces.Cryoconite holes are oases of microbial diversity on ice surfaces.Distinct community structures for cryoconite and ice-marginal communities were observed.Cryoconite holes are holes in a glacier's surface caused by sediment melting into the glacier.Although cryoconite holes, sediment-filled melt holes on glacier surfaces, appear small and homogenous, their microbial inhabitants may be spatially partitioned.Cryoconite holes are water-filled reservoirs on a glacier's surface and one of the most extreme ecosystems for micro-invertebrates. |
