Correction to: Hydrogeology Journal (2018)

https://doi.org/10.1007/s10040-018-1815-1

Editor’s Note:

The country map in Fig. 1a was published following the policy of Hydrogeology Journal to display country names and borders, in accordance with United Nations guidance: http://www.un.org/Depts/Cartographic/map/profile/morocco.pdf

Hydrogeology Journal’s policy is neutral regarding jurisdictional claims in published maps and institutional affiliations. Following publication, the authors expressed a preference to display a different representation of the region; however, figures cannot be replaced in published articles.

Thus, this Correction modifies the Fig. 1a caption to read as follows:

The orange circles represent the sampled Turonian aquifer points; the pink circles represent the Plio-Quaternary sampled points. b-c Schematic cross sections of Essaouira sedimentary basin.
