Time series of salinity and ions concentrations in Lake Urmia, Iran

This data contains time series of TDS and ions concentrations in Lake Urmia from 1977 to 2017. We used data of East Azarbaijan Water Bureau (EAWB) which has been collected from four locations near the causeway bridge since 2005 at monthly intervals. As these data were all associated with the saturated brine condition, we also used published data prior to 2005 to obtain a complete picture of changes in lake salinity related to changes in lake elevation. To be consistent, we only used the data gathered from the surface strata (0-0.5 m).
