The primary objective was to document paleoclimatic and paleoceanic changes in the subtropical Eastern North Atlantic over the Quaternary.
We present pollen raw data from the samples analyzed between 79-92 crmcd, and 120-125 crmcd for 339-U1385, 293-392 mcd and 419-449 mcd for 339-U1386. At site 339-U1385, most of the pollen analysis was performed at 4 cm resolution, while for 339-U1386, the resolution is 10-30 cm. 926 samples were analyzed for pollen grains and spores. Sample preparation followed standard palynological protocols using HCl and HF. The final residues were mounted unstained in bidistilled glycerin, a mobile mounting medium that allows rotation of pollen grains and spores. Pollen and spores were identified using a Zeiss Axio Imager A10 light microscope at 400X and 1000x magnifications. In most of the samples, a minimum of 100 pollen grains, excluding Pinus, and 20 pollen morphotypes were counted.-10.126027-7.75536.82837.5714158
