Dinoflagellate cyst and pollen assemblages as tracers for marine productivity and river input in the northern Gulf of Mexico

Yord W. Yedema, Timme Donders, Francien Peterse, and Francesca Sangiorgi

Data sets

Soil-, fluvial-, plant- and marine derived organic carbon from surface sediments (0-2 mcm) from the northern Gulf of Mexico Y. W. Yedema, F. Sangiorgi, A. Sluijs, J. S. Sinninghe Damste, and F. Peterse https://doi.org/10.1594/PANGAEA.944838

Short summary

The pollen and dinoflagellate cyst content of 21 surface sediments from the northern Gulf of Mexico is used to test the applicability of three palynological ratios (heterotroph/autotroph, pollen/dinocyst, and pollen/bisaccate ratio) as proxies for marine productivity and distance to the coast/river. Redundancy analysis confirms the suitability of these three ratios, where the H/A ratio can be used as an indicator of primary production, and the P/B ratio best tracks the distance to the coast.
