Pollen-based vegetation reconstruction from IODP Site 339-U1385, drilled on the SW Iberian margin during IODP Expedition 339 (37°34.285′ N, 10°7.562′ W; 2578 m water depth). The studied interval between 537 and 460 ka includes Marine Isotope Stage 13 (MIS 13, ~533-478 ka) and provides a centennial-scale resolution record of SW Iberian vegetation and associated changes in regional hydroclimate.The dataset contains counts of all identified pollen and spore morphotypes, as well as the main ecological groups: Mediterranean forest (including Mediterranean sclerophylls and all temperate trees and shrubs, excluding Pinus, Cedrus and Cupressaceae), Mediterranean taxa s.s. (or sclerophylls), and semi-desert plants.Pollen analysis: A total of 265 levels from Site U1385 were sampled for pollen analysis every 2-4 cm. Samples were prepared following the standard marine palynological protocol, which includes coarse sieving at 150 µm, successive cold HCl and HF treatments to remove carbonates and silicates, a final 25 % HCl step to eliminate fluorosilicates, and micro-sieving at 10 µm. Residues were mounted unstained in glycerol. Pollen analysis was carried out using a Nikon light microscope at ×500 and ×1000 (oil immersion) magnification.

However, due to discontinued communication from the authors' side, it did not receive the usual formal approval by the authors and therefore lacks final scientific validation.
