黄海沿岸沿着全新世海平面变化的研究，以往的研究都是以泥炭等生物标志物作为相对海平面的古指示物，但在重建上存在矛盾。在这项研究中采用的另一种代理指标的海平面变化的发光测年技术从残留的前沙丘结构上的构造稳定的一段韩国西海岸的石英砂。所获得的年表是一致的相对海平面是非常接近或高于目前在该期间约。6-5 ka.这样的年龄并不符合雅阁上升，在整个全新世，如一些早期的研究所建议的。在这项研究中确定的中全新世高水位表明，海平面变化沿着黄海海岸线是一致的海平面曲线报告从其他远场站点，地壳水均衡调整可能导致的海岸线在晚全新世的瞬态回归。
Abstract Previous studies of Holocene sea-level change along the Yellow Sea coastline present conflicting reconstructions, and such investigations have invariably used peat as well as other biological markers as paleo-indicators of relative sea level. An alternative proxy indicator of sea-level change is employed in this study by applying the luminescence dating technique on quartz sands retrieved from relict foredune structures on a tectonically stable section of the west coast of Korea. The chronologies obtained are consistent with a relative sea level that was very close to or higher than present during the period ca. 6–5 ka. Such ages do not accord with a sea level that rose continuously throughout the Holocene, as is suggested by some earlier studies. The mid-Holocene highstand identified in this study indicates that sea-level change along the Yellow Sea shoreline is congruous with sea-level curves reported from other far-field sites at which crustal hydroisostatic adjustment presumably led to the transient regression of coastlines during the late Holocene.
