Short summary
Here we examine the diversity and activity of microbes inhabiting different types of basal ice. We combine this with a meta-analysis to provide a broad overview of the specific microbial lineages enriched in a diverse range of frozen environments. Our results indicate debris-rich basal ice horizons harbor microbes that actively conduct biogeochemical cycling at subzero temperatures and reveal similarities between the microbiomes of basal ice and other permanently frozen environments.
