Abstract

The mechanisms of maintenance of earth hummocks and non-sorted stripes in seasonally frozen ground on the Old Man Range, Otago, were investigated. An array of thermistors at each of 2 sites was used to monitor soil temperature gradients during 3 winters, and replicate soil cores were taken in autumn and winter to determine soil moisture gradients. Freezing occurred mainly in the crests and sides (heavily influenced by aspect), and patterns of freezing showed strong interannual consistency. Soil in crests had a higher moisture content in both freezing and thawed seasons, which was inconclusive relative to the expected water gradient
