Ace lake is a stratified lake in the Vestfold Hills, Antarctica. The presence of a thick ice-cover for ~11 months of the year and a strong salinity gradient are responsible for its permanent stratification. Taxonomy analyses showed depth-based segregation of its microbial community, including viruse...
