“…1). Here, we investigate the potential impact of this process on the evolution of the eastern Southern Alps based on segregation ice weathering theory (Taber, 1929;Walder and Hallet, 1985;Hallet et al, 1991;Wettlaufer and Worster, 1995;Wilen and Dash, 1995;Wettlaufer et al, 1996;Worster and Wettlaufer, 1999;Zhu et al, 2000;Murton et al, 2001;Rempel et al, 2004;Murton et al, 2006;Dash et al, 2006). This paper is driven by a number of key research questions: What is the potential effect of periglacial erosion on the evolution of a mountain range?…”

“…Contrary to popular belief, the 9% volumetric expansion associated with the water-ice phase transition has essentially nothing to do with frost heaving in soils. In fact, a number of experiments have demonstrated 'frost heaving' by materials that contract upon freezing [12], more recently using helium [13] and argon [14]. For all practical purposes, frost heaving in nature is due to the addition of water to freezing soils as water is thermodynamically drawn to the freezing front from nearby areas [15].…”

Distinct surface patterns are ubiquitous and diverse in soils of polar and alpine regions, where the ground temperature oscillates about 0°C. They constitute some of the most striking examples of clearly visible, abiotic self-organization in nature. This paper outlines the interplay of frost-related physical processes that produce these patterns spontaneously and presents unique data documenting subsurface soil rotational motion and surface displacement spanning 20 years in well-developed circles of soil outlined by gravel ridges. These sorted circles are particularly attractive research targets for a number of reasons that provide focus for this paper: (i) their exceptional geometric regularity captures the attention of any observer; (ii) they are currently forming and evolving, hence the underlying processes can be monitored readily, especially because they are localized near the ground surface on a scale of metres, which facilitates comprehensive characterization; and (iii) a recent, highly successful numerical model of sorted circle development helps to draw attention to particular field observations that can be used to assess the model, its assumptions and parameter choices, and to the considerable potential for synergetic field and modelling studies.

“…II.A͒. Although the approximation is strictly valid for melt layer thicknesses greater than the interface width, the theory in some cases can provide a moderately successful description of the quasiliquid down to thicknesses of one or two layers ͑Frenken and van der Veen, 1985;Zhu and Dash, 1986͒. Further connections between surface melting and the bulk transition are discussed in a recent review ͑Dash, 2002͒, the role of surface melting on crystal growth is discussed in Sec. IV.E, and the closely related issue of surface roughening is discussed presently.…”

“…Similar studies were carried out on Al and other crystals, with similar results. Calorimetric techniques were used in studies of surface melting of thick films of Ar and Ne ͑Zhu and Dash, 1986͒. The films were adsorbed on exfoliated graphite, a substrate that has been useful in many studies of adsorbed films, since it provides high areas of well-ordered basal plane facets.…”

The surface of ice exhibits the swath of phase-transition phenomena common to all materials and as such it acts as an ideal test bed of both theory and experiment. It is readily available, transparent, optically birefringent, and probing it in the laboratory does not require cryogenics or ultrahigh vacuum apparatus. Systematic study reveals the range of critical phenomena, equilibrium and nonequilibrium phase-transitions, and, most relevant to this review, premelting, that are traditionally studied in more simply bound solids. While this makes investigation of ice as a material appealing from the perspective of the physicist, its ubiquity and importance in the natural environment also make ice compelling to a broad range of disciplines in the Earth and planetary sciences. In this review we describe the physics of the premelting of ice and its relationship with the behavior of other materials more familiar to the condensed-matter community. A number of the many tendrils of the basic phenomena as they play out on land, in the oceans, and throughout the atmosphere and biosphere are developed.
