Database used in Leiva-Dueñas et al. (2018). <i>Posidonia oceanica </i>is a marine phanerogam that buries a significant part of its belowground production forming an organic bioconstruction known as mat. Despite <i>Posidonia </i>seagrass mats have proven to be reliable archives of long-term environmental change, palaeoecological studies using seagrass archives are still scarce. Here we reconstruct four millennia of environmental dynamics in the NE coast of Spain by analysing the carbon and nitrogen elemental and stable isotopic composition of <i>P. oceanica </i>sheaths, the proportion of different seagrass organs, the carbonates and organic matter content as well as the grain-size distribution throughout the seagrass mat.<br>
