日本海冲木海岭798孔岩心选定层段280个样品的初步花粉分析结果（第798 A-1H-1至798 A-3 H-3、798 B-1H、798 B-13 H1至798 B-15 H-8条，798 C-1H-1 ~ 798 C-1H-3）表明：（1）日本植被的花粉类型丰富，在过去140万年的沉积物中保存完好; (2)798号站点快速沉积的沉积物中花粉的浓度、保存和组成为高分辨率的（3）798站沉积物中的花粉地层可与陆上相关年代的花粉地层直接对比;（4）798站沉积物中连续的、直接相关的上新世-更新世陆地/海洋古气候记录的建立，将为东北亚地区过去-2.4Ma的海洋和陆地古环境变化提供连续的高分辨率记录。
Results of preliminary pollen analyses of 280 samples from selected intervals of cores from Hole 798 on the Oki Ridge in the Sea of Japan (Sections 798A-1H-1 through 798A-3H-3,798B-1H, 798B-13H1 through 798B-15H-8, and 798C-1H-1 through 798C-1H-3) indicate that (1) diagnostic pollen types of the vegetation of Japan are abundant and well-preserved in sediments deposited over the last 1.4 m.y.; (2) the concentration, preservation, and composition of pollen in the rapidly deposited sediments of Site 798 provide a basis for high-resolution (on the order of ~500-year intervals) pollen stratigraphy in Pliocene-Plei stocene Japan Sea sediments; (3) the pollen stratigraphy of sediments from Site 798 can be directly correlated with pollen stratigraphies of correlative ages onshore; and (4) the development of continuous, directly correlative Pliocene-Pleistocene terrestrial/marine paleoclimatic records from sediments deposited at Site 798 will provide a continuous high-resolution record of northeast Asian marine and terrestrial paleoenvironmental changes for the past -2.4 Ma.
