| contents | 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 ~435 and 363 ka, encompasses Marine Isotope Stage (MIS) 11 and provides a high-resolution record of vegetation and terrestrial climate variability in southwestern Europe. 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: Holes E and D of Site 339-U1385 were sampled every 4 cm between 50.27 and 56.01 crmcd, with increased resolution (2 cm) between 54.50 and 56.01 crmcd during interglacial MIS 11c. Processing followed the standard protocol for marine samples: coarse sieving (150 µm mesh), sequential treatments with cold HCl (10-50 %) and cold HF (45-70 %) to remove carbonates and silicates, a final cold HCl (25 %) treatment to eliminate fluorosilicates, and micro-sieving at 10 µm. Residues were mounted unstained in glycerol. Pollen analysis of 164 samples was carried out using a Nikon light microscope at ×500 and ×1000 (oil immersion) magnification. |
