  • Non-sorted patterned ground in the High Drakensberg, Southern Africa : some new data
  • Africa ; Cryopedology ; Freeze-thaw cycle ; Humid environment ; Micromorphology ; Patterned ground ; Periglacial features ; Seasonal variability ; Southern Africa
  • This paper presents empirical data on non-sorted patterned ground in the high Drakensberg. Some morphological and sedimentary characteristics for thufur and non-sorted steps are provided. The study also examines process data on ground heave activity
  • at a thufur site. Contemporary cryogenic activity at the non-sorted steps is indicative that the patterns are at least seasonally active. Soil heave measurements at the Mashai Valley thufur site support the contention that some thufur are active in the high

  • This study uses a hydrologic/soil-temperature model to examine patterns of winter soil temperatures across southern Michigan, and in so doing sheds light on the meteorologic variables that affect soil freezing. Spatial patterns of soil freezing were
  • information not only on spatial patterns of soil freezing, but also on the interannual variability and, most importantly, pedo-climatic extremes.

  • . Climate has changed from humid subtropical (Oligocene) into frigid (subarctic) with tundra development (Late Pleistocene). All these conditions have formed recent surface pattern. Many processes are now very slow, but they changed many times in Late
  • Cenozoic. Each time interval was characterised by specific set of lead geomorphologic processes and of extreme, catastrophic, ones, which were locally distributed. Analysis of relief evolution allows to date the formation of the ground features'main types.

  • New constraints on the evolution of Carolina Bays from ground-penetrating radar
  • Ground-penetrating radar (GPR) data for the Savannah River Site (SRS) in the Upper Coastal Plain of South Carolina, combined with geological, archaeological, and ecological data place new constraints on the evolution of Carolina Bays. Extant SRS bay

  • The powerful sinergy between geostatistics and remote sensing went unrealized until the 1980s. Today geostatistics are used to explore and describe spatial variation in remotely sensed and ground data; to design optimum sampling schemes for image
  • data and ground data; and to increase the accuracy with wich remotely sensed data can be used to classify land cover or estimate continuous variables. This article introduces these applications and uses 2 examples to highlight characteristics
