Abstract
This paper analyzes static allometric relationships between the area supplying ice to a fjord glacier, and the fjord trough properties of length, width and depth. The analysis is guided by an underlying assumption that the fjords are eroded into a pre-glacial, fluvial landscape composed primarily of plutonic rocks. The relation between fjord length and ice contributing area appears to be isometric (i.e. the two variables change in constant proportion throughout the study area). Differing degrees of negative allometry exist between ice contributing area, and width, average depth and maximum depth. Abrasion rate models of Boulton and Hallet were applied to a V-shaped valley to gain insight into its transformation into a U-shaped trough; the results of the two models were compared.
