dc.description.abstract | 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. Understanding the differences in structure of
cryoconite across the globe can be important in recognizing past and future changes in supraglacial environments
and ice-organisms-minerals interactions. Despite the worldwide distribution and over a century of studies, the
basic characteristics of cryoconite, including its forms and geochemistry, remain poorly studied. The major purpose
of our study is the presentation and description of morphological diversity, chemical and photoautotrophs
composition, and organic matter content of cryoconite sampled from 33 polar and mountain glaciers around the
globe. Observations revealed that cryoconite is represented by various morphologies including loose and granular
forms. Granular cryoconite includes smooth, rounded, or irregularly shaped forms; with some having their
surfaces covered by cyanobacteria filaments. The occurrence of granules increased with the organic matter content
in cryoconite.Moreover, amajor driver of cryoconite colouringwas the concentration of organicmatter and
its interplay with minerals. The structure of cyanobacteria and algae communities in cryoconite differs between
glaciers, but representatives of cyanobacteria families Pseudanabaenaceae and Phormidiaceae, and algae families
Mesotaeniaceae and Ulotrichaceaewere themost common. Themost of detected cyanobacterial taxa are known
to produce polymeric substances (EPS) that may cement granules. Organic matter content in cryoconite varied
between glaciers, ranging from 1% to 38%. The geochemistry of all the investigated samples reflected local sediment
sources, except of highly concentrated Pb andHg in cryoconite collected fromEuropean glaciers near industrialized
regions, corroborating cryoconite as element-specific collector and potential environmental indicator of
anthropogenic activity. Our work supports a notion that cryoconite may bemore than just simple sediment and
instead exhibits complex structure with relevance for biodiversity and the functioning of glacial ecosystems | pl_PL |
