Local and regional constraints on relative sea‐level changes in southern Isle of Skye, Scotland, since the Last Glacial Maximum
ABSTRACT New relative sea‐level (RSL) data constrain the timing and magnitude of RSL changes in the southern Isle of Skye following the Last Glacial Maximum (LGM). We identify a marine limit at ~ 23 m OD, indicating RSL ~20 m above present c . 15.1 ka. Isolation basin data, supported by terrestrial...
