In exploring the temperature and salinity tolerances of bacteria in sea ice, we hypothesized a seasonal synergy between bacteria and algae, based on bacterial uptake and metabolism of compatible solutes. In this model, algae release choline into the brine pockets of new sea ice, which can then be co...
