Average shell size of plantkonic foraminifera from 28 stations in the Aegean and the Levantine Sea
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 Ott...
