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.

本数据集针对南极海洋性区域（乔治王岛阿尔克托夫斯基站）与沿海大陆性区域（威尔克斯地凯西站）的土壤，从土壤学、同位素环境及微生物环境三个维度展开系统描述。该区域土壤被划分为薄层土（Leptosols）、新成土（Regosols）、灰化土（Podzols）与有机土（Histosols）。仅1-3 cm的表层土壤含有足量有机质，可为微生物群落营造适宜的生存环境，同时促进有机质的累积过程。其生物学与化学性质在垂直深度方向的厘米级尺度内，以及水平方向的分米级尺度内，均存在显著空间变异。
