Volatile fatty and dissolved free amino acids in Organic Lake, Vestfold Hills, East Antarctica
The distributions of volatile fatty acids (C1-C5) (VFAs) and dissolved free amino acids (DFAAs) in Organic Lake, a shallow hypersaline meromictic lake in the Vestfold Hills, East Antarctica, were determined during the winter and spring of 1987. The concentrations of the two VFAs detected, formic and...
