For detailed quantitative micropalaeontological analysis, specimens of planktonic foraminifera were picked from about 3g of dry marine sediment, taken from the 1-2 topmost centimeters of the cores. After wet sieving, the dried coarse fraction was sieved through a 125 μm screen and split using an Otto micro-splitter into aliquots of at least 300 planktonic foraminifera specimens. The specimens were orientated and stabilized in separate cells on a Plumer microslide with tragacanth glue for and were photographed for assemblage size analysis. Images were acquired using a modular Leica M165 C fully apochromatic stereo microscope with an integrated 10 megapixel Leica IC90 E color camera (at 2× magnification) and processed using ImageJ software (version 1.50i). The image analysis system determines test 2-D (silhouette) areas and Feret's diameters for each aliquot. Foraminifera shells were positioned to capture the maximum silhouette area of each individual, corresponding to the umbilical or spiral sides, since the ...
