- Title
Sorted circles in the maritime Subantarctic, Marion Island .
- Authors
Holness, Stephen Dale
- Abstract
Reports that active sorted circles are quantitatively described for the first time for the maritime Subantarctic. How increasing altitude and hence increasing frost penetration are associated with systematic increases in pattern spacing, cell width, height of the fine centre relative to the border, and depth of sorting. Results results implying consistent dimensional scaling of circle parameters. It is argued, on the basis of the altitudinal trends in pattern morphology, the dimensional scaling of forms, and the morphology of the patterns, that differential frost heave in association with convection cells is responsible for circle formation.
