In 2020, Colby Gura and Scott Rogers extended their study of Lake Vostok accretion ice, as well as the basal ice flowing into the lake. They found that the basal ice contained an almost completely different community of organisms compared to those found in the lake accretion ice, indicating that they signified two completely different ecosystems. Additional bacteria and eukaryotes were reported. The highest diversity of organisms in the lake ice was significantly associated (p<0.05) with higher concentrations of ions and amino acids. The 2020 study again found the presence of bacteria that inhabit fish intestines and a molecular sequence closest to a rock cod common along the coast of Antarctica, Notothenia coriiceps, which produces antifreeze proteins.
