Global Surface water and groundwater salinity measurements (1980-2019)¶

This data contains a new global salinity database, compiled from electrical conductivity (EC) monitoring data of both surface water (rivers, lakes/reservoirs) and groundwater locations over the period 1980-2019. The database includes information from over 16.3 million samples, from 45,103 surface water locations and 208,550 groundwater locations around the world. You can download the dataset here. You can read the article here

Source Data Structure¶

The database consists of three categories; 1. River Data 2. Lake/Reservoir Data 3. Groundwater Data

Each category have two associated data files in csv-format, one containing the full salinity data, and one summary file currently the full salinity datasets are ingested.
