Frost flowers (FF) have been studied for their potential influence on ice-surface reflectivity and roles in atmospheric chemistry, but not as microbial habitats. We examined FF grown in a freezer laboratory from a bacteria-containing saline solution and FF formed naturally in the coastal (April) and central Arctic Ocean (September). All FF contained bacteria (up to 3.46 x 10(6) ml(-1) in natural FF) with densities 3-6-fold higher than in underlying ice. Bacterial abundance correlated strongly with salinity in FF (p values
