    dct:description "This gridded dataset represents the first continental?scale compilation of groundwater salinity across Africa, derived from 12,255 in situ measurements assembled by Gurmessa et al. (2022). The dataset is a gridded representation of electrical conductivity (EC) point data collected across Africa and compiled by the British Geological Survey. The dataset is a spatially continuous representation of groundwater salinity across the diverse hydrogeological and climatic environments of the African continent. A detailed description of source of the data, the dataset itself and methodology used to construct it, is provided at the following link: https://www.sciencedirect.com/science/article/pii/S0048969722013754#s0010" ;
