metadata.value: Soils of the Gydan Peninsula have been investigated during the
  complex expedition “Yamal Arctica 2013” during the “Professor Molchanov”
  vessel route in August and September 2013 with special aim to characterize
  soil morphology in relation with parameters of electric resistivity with use of
  vertical electric sounding methodology. Data obtained show that soils investigated
  are quite different in terms of solum morphology, soil stratigraphy
  and active layer thickness. Main soil types of the Gydan Peninsula (Siberia,
  Russian Federation) are Cryosols with features of raw organic matter accumulation
  and gleyification features. These soils dominate on the watersheds and
  in lowlands due to poor drainage of parent materials and presence of continual
  permafrost in landscape. In some cases, two Gleyic layers formed in one soil
  profile – one in the upper or middle part due to seasonal fine earth over moisting,
  and second one – on the contact of the solum with permafrost. Histic
  soils with Cryic features are more typical for lowlands (relief depressions).
  Soils of the Beliy Island are presented by slightly podsolised soils in upper
  part, this is due to lithological contrast of sediments (sandy textured solum
  changes by loamy textured one). The Electric resistivity (ER) was measured
  directly in the soil profiles with using the vertical electrical sounding (VERS)
  method, which provides data on the changes in the electrical resistivity
  throughout the profile from the soil surface without digging pits or drilling.
  This method allows to divide the soil pit vertically into layers with different
  properties. A VERS modification with shorter electrode spans was used to
  study the upper up to 5-m thick layer in detail. The distance between the A and
  B electrodes was from 5 to 500 cm. Soils have been sounded be thoroughly
  from the 5 cm to 3-5 m in depth. It was shown that use of VERS methodology
  in soil survey is quite useful for identification of the permafrost depth without
  digging of soil pit. This method allows identify soil heterogeneity, because
  the ER values are strongly affected by soil properties and intensively changes
  on the border of different geochemical regimes, i.e. on the border of active
  layer and permafrost. VERS data obtained show that the upper border of the
  permafrost layer coincides with that border, which were identified in field on
  the base of soil profile morphology. The VERS method also can be used for
  identifycation of Gleyic, Histic and Podzolic layers. VERS methodology is
  useful for preliminary soil survey in the regions with permafrost affected soil
  cover. It is also can be applie
