Fig. 9.5 Gradient in soil-forming processes in Antarctica (Goryachkin et al. 2004 )
Humigelepts, Dystrogelepts), or Histosols (Cryofi brists, Cryohemists, Cryosaprists,
and Cryofolists). These soils occur almost exclusively along the western Antarctic
Peninsula and at elevations below 50 m in the SSI and SOI; these organic soils may
contain permafrost below 2 m. We suggest that ornithogenic soils occupy only
0.5 % of ice-free areas in Antarctica, but this may be an underestimate.
