MIS 9 pollen records from sediment core MD03-2697, Northwest Iberian Margin

The marine pollen record from NW Iberian margin sediments (core MD03-2697) covers the interval between 340 000 and 270 000 years ago, a time period centred on Marine Isotope Stage (MIS) 9. This dataset consists of pollen data enabling the documentation of vegetation changes in the north-western Iberian Peninsula and therefore the terrestrial climatic variability at orbital and in particular at millennial scales during MIS 9, directly on a marine stratigraphy.
