Description :
The flow of ice sheets and their geomorphological impact is greatly influenced by their basal thermal regime. In this paper the AA. introduce an Excel spreadsheet method for calculating basal ice temperature along a one-dimensional flowline of an ice sheet. The first example provides a calculation of basal thermal regime beneath the north eastern part of the Scottish ice sheet during the last glacial maximum, the second shows how basal ice temperatures can be calculated beneath the modern Antarctic ice sheet.
