Soil investigations at Casey and Arctowski stations

Soils from the maritime (Arctowski Station, King George Island) and coastal continental (Casey Station, Wilkes Land) Antarctic region are described with respect to pedology, isotopic and microbial environments. They are classified as leptosols, regosols, podzols, and histosols. Only surface layers (1-3 cm) contain sufficient organic material to provide a favourable environment for microbial communities and, further, for accumulations of organic matter. Variability of biological and chemical properties is high on a centimeter scale with depth and in the range of decimeters in horizontal scales.

本数据集对南极洲海域（阿克托夫斯基站，乔治王岛）和沿海大陆（凯西站，威尔克斯地）的土壤进行了描述，涉及土壤学、同位素和微生物环境。这些土壤被归类为贫瘠土、石质土、灰化土和泥炭土。仅表层（1-3厘米）含有足够的有机物质，为微生物群落提供有利环境，进而有利于有机物质的积累。在厘米尺度上，生物和化学性质随深度变化而呈现高度可变性，而在十厘米尺度上，水平尺度范围内亦表现出显著差异。
