A 10 B e‐based reconstruction of the last deglaciation in southern S weden

We present 23 cosmogenic surface exposure ages from 10 localities in southern S weden. The new 10 B e ages allow a direct correlation between the east and west coasts of southern S weden, based on the same dating technique, and provide new information about the deglaciation of the F ennoscandian I ce S heet in the circum‐ B altic area. In western S kåne, southernmost S weden, a single cosmogenic surface exposure sample gave an age of 16.8±1.0 ka, whereas two samples from the central part of S kåne gave ages of 17.0±0.9 and 14.1±0.8 ka. Further northeast, in southern S måland, two localities gave ages ranging from 15.2±0.8 to 16.9±0.9 ka (n=5) indicating a somewhat earlier deglaciation of the area than has previously been suggested. Our third locality, in S S måland, gave ages ranging from 10.2±0.5 to 18.4±1.6 ka (n=3), which are probably not representative of the timing of deglaciation. In central S måland one locality was dated to 14.5±0.8 ka (n=3), whereas our northernmost locality, situated in northern S måland, was dated to 13.8±0.8 ka (n=3). Samples from the island of G otland suggest deglaciation before 13 ka ago. We combined the new 10 B e ages with previously published deglaciation ages to constrain the deglaciation chronology of southern S weden. The combined deglaciation chronology suggests a rather steady deglaciation in southern S weden starting at c . 17.9 cal. ka BP in NW S kåne and reaching northern S måland, ∼200 km further north, c.  13.8 ka ago. Overall the new deglaciation ages agree reasonably well with existing deglaciation chronologies, but suggest a somewhat earlier deglaciation in S måland.
