Ice elevations and surface change on the Malaspina Glacier, Alaska
[1] Here we use Ice, Cloud and land Elevation Satellite (ICESat)-derived elevations and surface characteristics to investigate the Malaspina Glacier of southern Alaska. Although there is significant elevation variability between ICESat tracks on this glacier, we were able to discern general patterns in surface elevation change by using a regional digital elevation model (DEM) as a reference sur...
متن کاملSnow Cover Effects on Glacier Ice Surface Temperature
Snowpack evolution and glacier ice surface temperatures were studied on the Indren glacier (Northwestern Alps, Italy) under different meteorological conditions: in winter 2002–2003, rich in snow from the beginning of the season, and in winter 2005– 2006, poor in snow until February. Periodical snow profiles were made to measure the physical properties of snow, while data loggers measured the sn...
متن کاملAdhesion between an elastic body and a randomly rough hard surface.
I have developed a theory of adhesion between an elastic solid and a hard randomly rough substrate. The theory takes into account that partial contact may occur between the solids on all length scales. I present numerical results for the case where the substrate surface is self-affine fractal. When the fractal dimension is close to 2, complete contact typically occurs in the macro-asperity cont...
متن کاملNano-Scale Effect in Adhesive Friction of Sliding Rough Surfaces
Study of contact and friction at multiple length scales is necessary for the effective design and analysis of surfaces in sliding microand nano-electromechanical systems (MEMS/NEMS). As loading forces decrease in such applications, the size of the asperity contacts tends to decrease into the nano scale regime. Also with the increase in surface area to volume ratio in such systems, the surface f...
متن کاملVelocity dependence of sliding friction on a crystalline surface
We introduce and study a minimal 1D model for the simulation of dynamic friction and dissipation at the atomic scale. This model consists of a point mass (slider) that moves over and interacts weakly with a linear chain of particles interconnected by springs, representing a crystalline substrate. This interaction converts a part of the kinetic energy of the slider into phonon waves in the subst...
