Low salinity and high-level UV-B radiation reduce single-cell activity in Antarctic sea ice bacteria
journal contribution
posted on 2023-05-17, 02:09 authored by Martin, AR, Hall, J, Ryan, KExperiments simulating the sea ice cycle were conducted by exposing microbes from Antarctic fast ice to saline and irradiance regimens associated with the freeze-thaw process. In contrast to hypersaline conditions (ice formation), the simulated release of bacteria into hyposaline seawater combined with rapid exposure to increased UV-B radiation significantly reduced metabolic activity.
