Lateglacial climate change and coastal evolution in western Jura, ScottishInner Hebrides

The geomorphic and sedimentological evidence for former sea-level changes i n the exposed coastline of western Jura shows a clear coastal response to p ast changes in climate. In particular the rapid and high-magnitude climate changes associated with the onset and termination of the Younger Dryas appe ar to have been accompanied by major changes in coastal response. In wester n Jura, the temperate climate of the Lateglacial Interstadial was associate d with beach-ridge deposition, with the earlier part of this period being a ssociated with larger ridges than the latter. By contrast, the cold climate during the Younger Dryas appears to have been dominated by frost processes , sea-ice development and rapid rates of coastal erosion of bedrock. Cold-c limate shore erosion of bedrock appears to have ended suddenly at the close of the Younger Dryas.
