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…
