“…Two of these, Lakes Bonney and Vanda, have received considerable attention from biologists and geologists (Armitagc and House 1962;Angino and Armitage 1963;Wilson and Wellman 1962;Goldman 1963). While investigating the biology of some of these lakes, Armitagc and House (1962) discovered that Lakes Bonney and Vanda had unusual and contrasting thermal fcaturcs.…”

The thermal structures of Lakes Vanda and Bonney in Victoria Land, Antarctica, are examined and the heat balance of Lake Vanda evaluated. Both lakes are permanently ice‐covered and have high salt concentrations that increase with depth. The deep water of Lake Vanda is very warm (25C), while that of Lake Bonney is cold (−2.8C). Lake Vanda gains heat from solar radiation and by conduction from the bottom. All the heat gained is accounted for by melting of the undersurface of the ice and evaporation from the upper surface. Changes in sensible heat storage in the water in both lakes are extremely small. Lake Vanda has four layers of constant density water that are maintained by convective circulation driven by heating from below. The existence of a strong circulation in the thickest of these layers is demonstrated by a radioactive tracer experiment that revealed a horizontal current of 1 cm/sec at 20 m and some vertical mixing. No evidence of convective activity was found in Lake Bonney. Hypotheses put forth by other workers to explain the warm water of Lake Vanda by solar heating alone and by subsurface advection from thermal springs are considered and rejected.

“…Oxygen and carbon isotopic ratios were determined by standard procedures using a Nuclides Analysis Associates 6-60 double collector, double inlet mass spectrometer. Many writers have speculated on the history of Lake Bonney (Armitage & House 1962;Angino & Armitage 1963;Angino et al 1964;Hoare et al 1964;Shirtcliffe 1964;Shirtcliffe & Benseman 1964;House et al 1966;Boswell et al 1967). It has been suggested that the salts represent trapped sea water which has been somewhat modified by later processes of evaporation, addition of ions from surrounding soils and warm spring water, and the precipitation of CaS0 4, CaC0 3, and Na 2S0 4 (Angino et al 1964).…”

ABSTRACT. Th e upper 180 ft. (55 m .) of Lake Vanda in Wright Vall ey, south V ictori a Land, is essentia ll y potable, whe reas tha t part be low 200 ft.
