对采自刚果河口附近（6°35.6′S/10°19.1′E）的GeoB 1008-3柱状样的孢粉学研究提供了近190 ka来赤道非洲西部植被和气候变化的信息。花粉图分为1-6区，被认为是在时间上与海洋同位素阶段1-6相对应。在冷阶段6期间，显示出温度和湿度的振荡。在第5阶段，有两个较冷的时期（5d和5 b），表现为以低地雨林为代价，竹柏林向低海拔扩展。在高海平面时期（第5和第1阶段），沿着存在着扩展的红树林沼泽。
Palynological investigation of the marine core, GeoB 1008-3, from near the mouth of the Congo river (6°35.6′S/10°19.1′E), provides information about the changes in vegetation and climate in West Equatorial Africa during the last 190 ka. The pollen diagram is divided into zones 1–6 which are considered to correspond in time with the marine isotope stages 1–6. Oscillations in temperature and moisture are indicated during the cold stage 6. During stage 5, two cooler periods (5d and 5b) can be shown with an expansion of Podocarpus forests to lower elevations on the expense of lowland rain forest. Extended mangrove swamps existed along the coast in times of high sea level (stages 5 and 1).
