Database used in Leiva-Dueñas et al. "Millennial-scale trends and controls in Posidonia oceanica (L. Delile) ecosystem productivity". Posidonia oceanica is a marine phanerogam that buries a significant
part of its belowground production forming an organic bioconstruction known as
mat. Posidonia 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 P. oceanica sheaths, the proportion of
different seagrass organs, the carbonates and organic matter content as well as the grain-size distribution throughout the seagrass mat.
