Glaciers and ice sheets, like other biomes, occupy a significant area of the planet and
harbour biological communities with distinct interactions and feedbacks with their physical …

Polar ice sheets and mountain glaciers, which cover roughly 11% of the Earth's land surface,
store organic carbon from local and distant sources and then release it to downstream …

Cryoconite is granular sediment found on glacier surfaces comprising both mineral and
biological material. Despite long having been recognised as an important glaciological and …

Cryoconite is a mixture of mineral and organic material covering glacial ice, playing
important roles in biogeochemical cycles and lowering the albedo of a glacier surface …

Earth's surface is deficient in available forms of many elements considered limiting for
prebiotic chemistry. In contrast, many extraterrestrial rocky objects are rich in these same …

Surface ablation of the Greenland ice sheet is amplified by surface darkening caused by
light‐absorbing impurities such as mineral dust, black carbon, and pigmented microbial …

Runoff from small glacier systems contains dissolved organic carbon (DOC) rich in protein-
like, low molecular weight (LMW) compounds, designating glaciers as an important source …

During the freeze-thaw cycles of ice-covered lakes, DOM undergoes a series of
transformations including enrichment, dispersion, and filtration. However, the mechanisms …

Glaciers and ice sheets are significant sources of dissolved organic carbon and nutrients to
downstream subglacial and marine ecosystems. Climatically driven increases in glacial …

Albedo—a primary control on surface melt—varies considerably across the Greenland Ice
Sheet yet the specific surface types that comprise its dark zone remain unquantified. Here …
