1992—1993年用浅地层剖面仪对南黄海中部浅地层进行测量，在70—80m左右的深水区发现了埋藏古三角洲堆积体。结合实测海底地形图及岩芯沉积相资料对浅地层剖面进行综合分析。结果表明，该区域是距今2．7万a左右的黄河河口三角洲，这说明，晚更新世末期黄河已经流入南黄海陆架区，水深70—80m附近曾经发育一期古海岸线 In 1992-1993, the shallow stratum profiler was used to measure the shallow stratum in the central part of the South Yellow Sea. The buried paleo-delta deposit was found in the deep water area of ​​about 70-80m. Combined with the measured seafloor topographic maps and core sedimentary facies data, the shallow stratigraphic sections are comprehensively analyzed. The results show that the area is about 27,000 a year ago, the Yellow River mouth delta, indicating that the late Pleistocene Yellow River has flowed into the South Yellow Sea shelf area, the depth of 70-80m once the development of an ancient coastline
