An investigation of foraminifera was conducted in the last glacial loess along the coast of the Bohai Sea. Some deep-water planktic foraminifera were found in the loess in the southern Yellow Sea and the East China Sea; they are: Globigerina falconensis, Globorotalia pumilio and Neogloboquadrina dutertrei. The authors anal-ysed the abundance of the foraminifera and the frequency of planktic foraminifera appearance in two different loess sections, and available data indicate that the abundances and frequencies of fossils have significant differ-ences. The abundance and frequency of the fossils from the section distributed on the northern hillside are high-er than those of the fossils from the section distributed on the southern hillside. The authors therefore interpret that the Aeolian dust was carried not only by the northwesterly and northeasterly monsoons from the Bohai Sea but also by the southeasterly monsoon from the southern Yellow Sea and the East China Sea during the last glacial stage.
