Biogeochemistry of Onithogenic Soils in Coastal Antarctica
Ornithogenic soils are usually considered to be formed as a result of breeding activities by sea birds. These soils are widespread in polar regions and in Coastal Antarctica in particular. It is believed that the most important impact of birds on soil formation in such environments is accumulation o...
