Geophysical data are used with ice flow models and generalized accumulation histories to estimate age and annual layer thickness versus depth for two anticipated ice core sites in West Antarctica: Siple Dome (81.65°S, 148.81°W) and an inland site on the West Antarctic Ice Sheet (WAIS). This modeling experiment predicts that 10 4 year‐old ice is at ∼50% depth and 10 5 year‐old ice is at ∼90% depth at both sites. Both of these cores could contain climate information through the last glacial cycle with annual resolution through the Holocene. The predicted similarity in resolution and record length between the two cores suggests that they could be compared in detail to obtain both spatial and temporal information about the paleoclimate and history of the West Antarctic ice sheet.
