Pollen data from sediment core MD01-2444 on the Portuguese Margin, Marine Isotope Stage 3 ...
Pollen analysis: Sediment samples of 1.5-4 cm3 were prepared for pollen analysis using the standard hot acid digestion technique. Fine sieving, through a mesh of 10 m or less, was not used as it could result in a loss of pollen. Residues were mounted in silicone oil for microscopic analysis at magni...
