Ice-Gliding Diatoms: Arctic Motility at Record Low Temps
Across the Arctic ice, diatoms persevere in a world of brine channels and shimmering ice. Our study provides direct cellular observations of ice-dwelling diatoms within frozen matrices, revealing an unexpected capability: ice gliding. Unlike temperate diatoms, these Arctic relatives appear to navigate by gliding along icy substrates, a skill that opens access to light, nutrients,…

Low Temperature Limits for Motility in Arctic Ice Diatoms
Overview: Arctic ice diatoms and ice gliding In the harsh Arctic environment, ice-dwelling diatoms endure extreme cold, variable brine pockets, and constrained liquid pathways within the ice. Our study provides direct cellular observations of these microorganisms embedded in ice and reveals a previously undocumented ice-gliding ability that helps them navigate the ice matrix to reach…
