Persistence of bacterial and archaeal communities in sea ice through an Arctic winter
Summary The structure of bacterial communities in first‐year spring and summer sea ice differs from that in source seawaters, suggesting selection during ice formation in autumn or taxon‐specific mortality in the ice during winter. We tested these hypotheses by weekly sampling (January–March 2004) o...
