研究了三个发育良好的上升海岸线沿着Nordenskioldkysten和自末次冰消期以来的海岸线位移。该地区64米的海平面界限属于Weichselian晚期，已被确定为10，900 - 11，000年B.P.。50米的中间水平估计为10，600 - 10，000年，表明海平面停滞可能是由新仙女木期斯瓦尔巴特群岛东部的冰川再进造成的。全新世海侵在距今6,000年后不久达到高潮，地层学上已经证实，它可能与斯堪的纳维亚半岛的塔普斯海侵有关。没有发现前晚Weichselian海洋水平，大反弹只能归因于晚Weichselian冰川作用。
Three well-developed raised marine shorelines along Nordenskioldkysten have been studied and correlated with the shoreline displacement since the last deglaciation. The marine limit of 64 m in the area is of Late Weichselian age and has been dated to 10,900- I1,OOO years B.P. An intermediate level at 50 m is estimated to be 10,600-10,000 years old and demonstrates a sea level stagnation probably caused by a glacier readvance in eastern Svalbard during the Younger Dryas. A Holocene transgression culminating shortly after 6,000 years B.P. has been stratigraphically demonstrated, and it probably correlates with the Tapes transgression of Scandinavia. No pre-Late Weichselian marine levels are found, and the large rebound can be attributed only to a Late Weichselian glaciation.
