Database used in Leiva-Dueñas et al. "Millennial-scale trends and controls in Posidonia oceanica (L. Delile) ecosystem productivity". <i>Posidonia oceanica </i>is a marine phanerogam that buries a significant part of its belowground production forming an organic bioconstruction known as mat. <i>Posidonia </i>seagrass mats have proven to be reliable archives of long-term environmental change. 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>
