基于１９９６年中法合作在东海陆架进行的电火花单道地震调查资料，并与位于东海外陆架钻孔ＤＺＱ４对比，发现对应于氧同位素６期以来的六个地震地层与钻孔地层呈现很好的对应关系，其间共有四次海退—海进的沉积旋回。资料分析表明东海第四纪环境演变与全球气候冷暖变化所导致的海面升降直接相关。东海陆架受太平洋潮波系统控制的历史久远，在地震地层中，保留了相当于氧同位素７期（或９期）、５期、３期和１期海侵早期的潮流沙脊地层
Based on the EDM single channel seismic survey conducted on the East China Sea shelf by the Sino-French cooperation in 1996 and contrasted with the DZQ4 drilling in the continental shelf in the East China Sea, it is found that the six seismic strata and borehole formations corresponding to the stage 6 of oxygen isotope show good results In the meantime, there have been four regression-sedimentary cycles of Haijin. Data analysis shows that the evolution of the Quaternary environment in the East China Sea is directly related to the sea level rise and fall caused by the global climate change. The East China Sea shelf is controlled by the Pacific tidal wave system for a long time. In the seismic strata, tidal sand ridge formations corresponding to 7 (or 9), 5, 3 and 1 stages of transgression of oxygen isotopes are retained
