  • Ground temperature variability on a glacier foreland, Storbreen, Jotunheimen, Norway
  • , mimic ground temperature patterns. Although no wintertime field observations are available, the depth and duration of seasonal snow cover appears to be the primary source of variability.
  • This paper presents an analysis of ground temperature variation (10 cm and 50 cm) gathered from August 1998 through July 2000 across the glacier foreland of Storbreen, a cirque glacier in the Jotunheimen Mountains. Categorical data in the form

  • 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

  • The AA. hypothesize that the spatial patterns of soil moisture control variations in vegetation production, and hence remotely sensed greenness. They investigate the relationship between soil moisture and a remotely sensed greeness, the normalized

  • (1997/1998) snow cover. Results indicate that anomalously deep snow cover influenced the pattern of soil freeze-thaw depth through its control over ground temperature. Snow cover can also contribute to the cooling process through its high albedo

  • Winter ground surface temperature regimes in the zone of sporadic discontinuous permafrost, Tatra Mountains (Poland and Slovakia)
  • Ground surface temperatures in the zone of sporadic discontinuous permafrost in the Tatra Mountains were monitored over 2 winters at sites where either permafrost or deep seasonal frost had been previously posited. The results show that contemporary

  • Above-ground earthworm casts affect water runoff and soil erosion in Northern Vietnam
  • The AA. investigated the effects of Amynthas khami, an anecic species producing above-ground casts of prominent size, on water infiltration and soil detachment along a land-use intensification gradient. Two scales of studies were considered
