Comments Priscu et al. (ref 2) reported 10^3 to 3?10^4 microbial cells per milliliter in samples of accretion ice (refrozen from subglacial Lake Vostok water below the overlying glacial ice) at a depth of 3,590 m in an ice core from Vostok Station, Antarctica and Karl et al. (primary source) detected 200 to 300 per milliliter at 3,603 m. The high concentration was in a region containing rock fragments, and the low concentration was in ice without fragments.
