Estimation of annual layer thickness from stratigraphical analysis of Dome Fuji deep ice core [PDF]

, 2003
Dating of ice cores is of important but is difficult for an ice core where there is low snow accumulation, and also for the deep part because seasonal chemical and isotopic signals are not easily preserved due to vapor migration after snow deposition and
