Hydrothermal pattern of frozen soil in Nam Co lake basin, the Tibetan Plateau

Autor: Keming Tian, Shichang Kang, Wei Lu, Iain B. Campbell, Jingshi Liu, Fei Zhang, Qianggong Zhang

Publikováno v: Environmental Geology. 57:1775-1784

Hydrothermal processes and the regimes of frozen soil formed in alpine regions with glaciers and lake area are complex and important for ecological environment but have not been studied in Tibet. Based on soil temperature and moisture data from Octob

Permafrost distribution and active-layer depths in the McMurdo Dry Valleys, Antarctica

Autor: Iain B. Campbell, James G. Bockheim, Malcolm McLeod

Publikováno v: Permafrost and Periglacial Processes. 18:217-227

The McMurdo Dry Valleys (MDVs) constitute the largest ice-free area (6700 km2) in Antarctica. Permafrost is ubiquitous in the region and is present as ground ice or buried ice, ice-cemented permafrost and dry-frozen permafrost. Using a combined datas

Permafrost properties, patterns and processes in the Transantarctic Mountains region

Autor: Iain B. Campbell, G. G. C. Claridge

Publikováno v: Permafrost and Periglacial Processes. 17:215-232

The properties, distribution patterns and thermal processes that influence the active layer and permafrost in the Transantarctic Mountains region of Antarctica, as deduced from our soil investigations since 1964 and drilling investigations since 1990

Effects of hydrocarbon spills on the temperature and moisture regimes of Cryosols in the Ross Sea region

Autor: Iain B. Campbell, Megan R. Balks, Jackie Aislabie, John M. Kimble, Ron F. Paetzold

Publikováno v: Antarctic Science. 14:319-326

Hydrocarbon spills have occurred on Antarctic soils where fuel oils are utilized, moved or stored. We investigated the effects of hydrocarbon spills on soil temperature and moisture regimes by comparing the properties of existing oil contaminated sit

Morphogenesis of Antarctic Paleosols: Martian Analogue

Autor: Iain B. Campbell, David Malloch, D. Sheppard, Horton E. Newsom, William C. Mahaney, Victor R. Baker, Michael W. Milner, Ronald G.V. Hancock, James M. Dohm

Publikováno v: Icarus. 154:113-130

Samples of horizons in paleosols from the Quartermain Mountains of the Antarctic Dry Valleys (Aztec and New Mountain areas) were analyzed for their physical characteristics, mineralogy, chemical composition, and microbiology to determine the accumula

Movement of salts in Antarctic soils: experiments using lithium chloride

Autor: Iain B. Campbell, G. G. C. Claridge, Megan R. Balks

Publikováno v: Permafrost and Periglacial Processes. 10:223-233

In order to investigate the fate of contaminants accidentally spilt on Antarctic soils, known amounts of lithium chloride were added to soil plots beside Lake Vanda, in the Wright Valley, and close to Scott Base, on Ross Island. The soils were sample

Microtextures on quartz grains in tills from Antarctica

Autor: Iain B. Campbell, G. G. C. Claridge, William C. Mahaney

Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 121:89-103

Quartz grains of the sand (63–2000 μm) fractions from tills of Oligocene to Quaternary age in Antarctica were analyzed by scanning electron microscope (SEM) to test the hypothesis that relative ice thickness and distance of transport influence the

Heavy metal contamination in some soils of the McMurdo Sound region, Antarctica

Autor: Iain B. Campbell, Graeme G. C. Claridge, Z.H. Amin, H.K.J. Powell, Megan R. Balks

Publikováno v: Antarctic Science. 7:9-14

Soil samples from eight sites at Marble Point and Pram Point, McMurdo Sound region, contaminated by human activities were examined for heavy metal content, using sequential extraction methods. The redistribution of lead, zinc and copper arising from
