Maps showing the location of the study area.
(A) Location of the Alt Empordà and the Castellò lagoon in NE Spain with main vegetation types and archaeological sites mentioned in the text. (B) Detailed location of the EM core site in the EWNP, together with additional coring sites performed in the Castelló lagoon. The figure also shows the quick infilling process of the lagoon in the 2nd half of the 18th century as depicted in ancient maps.
