ocean microbiome

A new study reports that exposing an ocean water microbiome to controlled near-space conditions triggers a restructuring of its microbial community. The research, published via Astrobiology Web, suggests that stratospheric-level exposure — including low pressure, radiation and temperature extremes — can alter the composition of marine microbial populations. The findings may inform astrobiology research on microbial survival beyond Earth and the effects of high-altitude environments on ocean microorganisms.
