详细的岩石和生物地层分析从三个沿海站点在对比海岸设置斯凯岛，苏格兰，英国，揭示了几个变化的证据，在晚德文斯和全新世相对海平面。在记录开始时，该地区的相对海平面高约为1000米。12 500 14 C（约。14 800口径）但随后下降，在新仙女木时期达到一个低点，在约。11 000-10 000 14 C（约13 000-11 600口径）2000年BP，形成与主岩台对应的岩台。全新世早-中期，相对海平面上升约10%。8000 14C（ca. 8800口径）在东北Skye泻湖表面，与主要的冰后期海岸线，形成于约。6600 14C（ca. 7500口径）年血压。到全新世晚期，相对海平面再次下降，但上升，至少在两个地点登记，可能开始于公元前。4000 14C（ca. 4500口径）年BP，和第二泻湖表面在东北Skye，与Blairdrummond海岸线，形成，虽然由约。3000 14C（ca. 3200口径）2000 - 2005年，该地区相对海平面恢复下降趋势。所揭示的相对海平面变化模式与苏格兰其他地方的证据进行了比较。版权所有© 2006约翰威利父子有限公司。
Detailed litho‐ and biostratigraphical analyses from three coastal sites in contrasting coastal settings on the Isle of Skye, Scotland, UK, reveal evidence for several changes in relative sea level during the Late Devensian and Holocene. At the start of the record, relative sea level in the area was high at ca. 12 500 14C (ca. 14 800 cal.) yr BP but then fell, reaching a low point during the Younger Dryas, at ca. 11 000–10 000 14C (ca. 13 000–11 600 cal.) yr BP, when a rock platform, correlated with the Main Rock Platform, was formed. In the early–middle Holocene, relative sea level was rising by ca. 8000 14C (ca. 8800 cal.) yr BP and in northeast Skye a lagoonal surface, correlated with the Main Postglacial Shoreline, was formed at ca. 6600 14C (ca. 7500 cal.) yr BP. By the late Holocene, relative sea level was again falling, but a rise, registered at at least two sites, began probably before ca. 4000 14C (ca. 4500 cal.) yr BP, and a second lagoonal surface in northeast Skye, correlated with the Blairdrummond Shoreline, was formed, although by ca. 3000 14C (ca. 3200 cal.) yr BP relative sea level in the area had resumed its downward trend. The pattern of relative sea‐level changes disclosed is compared with evidence elsewhere in Scotland. Copyright © 2006 John Wiley & Sons, Ltd.
