The objective of this study is to calculate the RSL height at the location of theBerkner Island ice core during the last glacial cycle using a viscoelastic earth model andseveral glacial histories. Earlier glacial cycles are not considered, the basic assumptionbeing that the sediments were deposited during the last glacial cycle. However, tosome extent the results can be extrapolated further back into the past. The resultsimpose a constraint on the time of deposition of the sediments. Conversely, if thetime of deposition is determined, e. g. by luminescence dating, this study provides aconstraint on the glacial history of the Ronne Ice Shelf.
