The mystery of the ice cold rose—Microbiome of an Arctic winter frost flower
Abstract Under very cold conditions, delicate ice‐crystal structures called frost flowers emerge on the surface of newly formed sea ice. These understudied, ephemeral structures include saline brine, organic material, inorganic nutrients, and bacterial and archaeal communities in their brine channel...
