Identifying chronostratigraphic breaks in aeolian sediment profiles using near-surface luminescence dating and changepoint analysis

Abstract:

Optical dating of depositional profiles provides information on environmental change and dune reactivation in aeolian systems. However, identifying the optimum locations and samples for luminescence dating is often confounded by a lack of visible internal structures and a highly discontinuous and heterogeneous record. We use a method that combines high-resolution coarse luminescence signals with statistical changepoint analysis to identify significant chronostratigraphic breaks. The changepoi...
