Ice Diatoms Glide at Record-Low Arctic Temperatures
Ice Diatoms Break Ice on Motion in the Cold Hidden within the Arctic’s frozen seas are microscopic organisms that do more than survive. New research reveals that ice diatoms can actively glide through ice, seeking out better light and nutrient sources. In a combination of in situ fieldwork and laboratory experiments, these single-celled algae demonstrated…

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…
