High salinity represents an extreme environment in which relatively few organisms have been able to adapt and survive. Most halophilic and all halotolerant organisms expend energy to exclude salt from their cytoplasm to avoid protein aggregation ('salting out'). To survive the high salinities, halophiles employ two differing strategies to prevent desiccation through osmotic movement of water out of their cytoplasm. Both strategies work by increasing the internal osmolarity of the cell… WebEnrichment of Hydrogen Oxidizing Bacteria from High Temperature and Salinity Environments Appl Environ Microbiol. 2024 Nov 30;AEM.02439-20. doi: 10.1128/AEM.02439-20.

At high latitudes, salinity is low. This can be attributed to lower evaporation rates and the melting of ice that dilutes seawater. To sum up, salinity is low where precipitation is greater than evaporation, mainly in coastal or equatorial regions.
