Here we use an airborne transient electromagnetic (AEM) sensor to produce extensive imagery of resistivity beneath Taylor Valley. Regional-scale zones of low subsurface resistivity were detected that are inconsistent with the high resistivity of glacier ice or dry permafrost in this region. We interpret these results as an indication that liquid, with sufficiently high solute content, exists at temperatures well below freezing and considered within the range suitable for microbial life. These inferred brines are widespread within permafrost and extend below glaciers and lakes. One system emanates from below Taylor Glacier into Lake Bonney and a second system connects the ocean with the eastern 18 km of the valley. A connection between these two basins was not detected to the depth limitation of the AEM survey (~350 m).1 aMikucki, Jill, A.1 aAuken, E.1 aTulaczyk, S1 aVirginia, Ross, A.1 aSchamper, C.1 aSørensen, K., I.1 aDoran, Peter, T.1 aDugan, Hilary, A.1 aFoley, N.  uhttp://www.nature.com/doifinder/10.1038/ncomms783100572nas a2200157   4500008004100000245006300041210006000104260003600164100002100200700001600221700001700237700001600254700002500270700002700295856009200322       2008                        eng d00aAntarctic subglacial water: origin, evolution, and ecology0 aAntarctic subglacial water origin evolution and ecology  aOxfordbOxford University Press1 aPriscu, John, C.1 aTulaczyk, S1 aStudinger, M1 aKenicutt, M1 aChristner, Brent, C.1 aForeman, Christine, M.  uhttps://mcm.lternet.edu/content/antarctic-subglacial-water-origin-evolution-and-ecology
