This paper examines frozen fine-grained soils, mainly of Pleistocene and Holocene age, that are distributed along the Arctic coast at the surface and which contain soluble salts. Salinization is determined by both the conditions at formation
, and subsequent processes at cryogenic temperatures. An increase in salinization with depth is observed. This is most likely caused by moving of salts from the upper permafrost layers as the result of the migration of pore water. Salinization in general increases
with an increase in ice content. An important feature of the saline soils of the Russian Arctic coast is their heterogeneity.

Socio-economic data from a mail survey are combined in a GIS with other layers, including the location of discharge sites and depth to saline groundwater. Landholders in the upper catchment have excellent knowledge of the current extent of salinity
on their property. The extensive community education effort undertaken in this region has been successful in raising salinity awareness. But most landholders are not concerned about the impacts of dryland salinity and appear to believe they can live with salt
Saline groundwater problems in the Gaza Strip : causes and integrative management solutions
The Gaza Strip coastal aquifer is affected by increasing salinity and falling groundwater levels. Several authors believe these processes are related to the increasing water demand in the Gaza Strip corresponding to population growth during the past

The purpose of this study was to characterize geochemical variability in the basal LMBII deposits and thereby identify freshwater settings within the otherwise saline and alkaline Eastern Lacustrine Plain. Data on stone artifact and fossil bone

The AA. investigate interactions within a hyper-arid and hyper-saline weathering environment based on conditions observed in the Atacama Desert. The experimental design produced a matrix of 18 different weathering environments with 6 levels of salt
