Investigation of the physics (heat balance) and chemistry of Lake Bonney, Taylor Valley, 1962-1963

The heat balance and chemistry of Lake Bonney was investigated in the 1962-63 field season. Temperature profiles were measured through 11 holes drilled in the surface ice of Lake Bonney. Of these, the first two were shallow and of limited use, the last included readings at a few depths only and one contained an equipment error induced by last minute haste. The remaining 7 profiles provided good information. A radiation profile was also measured once. Samples were collected from melt streams at the eastern end of the lake and from one hole in the lake. The samples were analysed for ion concentration.
