Cryogenic origin for brine in the subsurface of southern McMurdo Sound, Antarctica
Sampling of interstitial fluids during deep coring in southern McMurdo Sound, Antarctica, revealed the presence of seawater-sourced, hypersaline brine at depths >200 m below the sea-floor. Na-Cl-Br and SO4-Cl-Br relationships are consistent with a concentration mechanism that involves the removal...
