The other Eden? Potential subsurface microbial habitat mapped out with Time-Domain Electromagnetic surveys beneath extreme polar desert of McMurdo Dry Valleys, Antarctica.

Abstract: Humanity’s best chance at direct scientific examination of life forms that do not belong to our own, terrestrial ‘Tree of Life’ will come from exploration of liquid water environments on cold planetary bodies in our Solar System. These include sub-ice oceans of Enceladus or Europa and sub-permafrost groundwaters of Mars. Antarctic deep groundwaters offer some of the best terrestrial analogs for such environments and can be used to develop techniques for identifying and accessing target extraterrestrial habitats. We have used a novel technique, helicopter-borne Time-domain ElectroMagnetics (TEM), to map out a regional briny groundwater system beneath one of the McMurdo Dry Valleys. This system appears to be connected to Blood Falls, which intermittently releases hyper saline brine at the snout of Taylor Glacier. As part of a follow-up project, we used a steerable ice-melting probe to sample pristine brine from an englacial conduit located just upstream of Blood Falls. These samples reveal that brine geochemistry and microbiology is different in these pristine samples than in samples collected over the past decades from the surface of Blood Falls. Deep subsurface Antarctic brines appear to support microbial life in spite of a number of challenging physical and chemical conditions.
