用高分辨率地球物理仪,在莺歌海陆架区海底发现了大量埋藏古河道、古湖泊。根据其分布位置及断面特征,推测出更新世末期低海面时期埋藏古水系的分布。据沉积物层中的超覆层序及埋藏古河道的端点水深推测,晚更新世末期调查区最低海平面的位置在130—140m等深线附近。
Using high-resolution geophysical instruments, a large number of buried ancient river courses and ancient lakes were found on the seabed of the Yingge Sea shelf area. Based on the distribution location and the characteristics of the sections, the distribution of the buried paleoealtic systems in the low Pleistocene epoch was estimated. According to the overlying sequence in the sediment layer and the water depth at the end of the buried ancient channel, the lowest sea level in the Late Pleistocene was near the 130-140 m isobath.
