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…

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 a Eukaryotic Cell: Ice-Gliding Diatoms in Arctic Ice
Introduction: Cold-Weather Motility and the Arctic Microbial World In the harsh Arctic environment, ice-entrapped diatoms persist and thrive far from temperate waters. These ice-dwelling phytoplankton navigate a frozen maze, accessing light and nutrients that would otherwise be out of reach. Our study presents direct cellular observations of diatoms embedded in ice and demonstrates a remarkable…

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…
