Ice lensing in layered soils

Canadian Geotechnical Journal, 1986
The ice lensing phenomenon in layered soils, a condition that simulates the process of ice growth in varved soils, has been studied experimentally. Under the limited conditions of layer thicknesses, soils used, freezing rates, and moisture conditions, ice lenses formed at the face of the fine-textured (clay) layer when it was encountered by the ...

The microlensing rate and distribution of free-floating planets towards the Galactic bulge [PDF]

, 2016
Ground-based optical microlensing surveys have provided tantalising, if inconclusive, evidence for a significant population of free-floating planets (FFPs).

Formation and growth of multiple, distinct ice lenses in frost heave

International Journal for Numerical and Analytical Methods in Geomechanics, 2022
AbstractThis paper presents a fully coupled thermo‐hydro‐mechanical (THM) model which simulates frost heave in fully saturated soils. The model is able to simulate the formation and growth of multiple distinct ice lenses. The basic equations of the system were derived using the continuum theory of mixtures, nonequilibrium thermodynamics, and fracture ...

Expectations from a Microlensing Search for Planets [PDF]

, 1996
The statistical distribution of the masses of planets about stars between the Sun and the center of the galaxy is constrained to within a factor of three by an intensive search for planets during microlensing events. Projected separations in terms of the

Ice Segregation as an Origin for Lenses of Non-Glacial Ice in “Ice-Cemented” Rock Glaciers [PDF]

Journal of Glaciology, 1981
AbstractIn order to flow with the gradients observed (10° to 15°) rock glaciers cannot be simply ice-cemented rock debris, but probably contain masses or lenses of debris-free ice. The nature and origin of the ice in rock glaciers that are in no way connected to ice glaciers has not been adequately explained.

Radio Echo Sounding: Absorption and Scattering by Water Inclusion and Ice Lenses [PDF]

Journal of Glaciology, 1972
AbstractThe absorption of radio waves propagating through naturally occurring waters varies greatly with the electrical conductivity. Glacier melt water is very transparent and the attenuation by melt water layers is due to reflexion of power, whereas the attenuation of sea-water layers is due to absorption.

Ice Lenses Beneath Hummocks in a Temperate Rich Fen

Wetlands, 2022
AbstractThe study documents a process of ice lenses persistence under hummocks during spring snowmelt in a rich fen in Poland. Air temperature, as well as the temperature under vascular plant litter, Hamatocaulis vernicosus mat, Tomentypnum nitens hummocks and Sphagnum teres hummocks, was measured from December to March using temperature data loggers ...

Neutrino Interferometry In Curved Spacetime [PDF]

, 2004
Gravitational lensing introduces the possibility of multiple (macroscopic) paths from an astrophysical neutrino source to a detector. Such a multiplicity of paths can allow for quantum mechanical interference to take place that is qualitatively different

Modeling of subsidence of anthropogenic soil containing ice lenses

Journal of Physics: Conference Series, 2019
Abstract The paper considers the possibilities of modelling of cyclic thermal effects on clastic water-saturated soil anthropogenic origin containing permafrost soil and ice lenses. In the formulation of the problem, there is uncertainty in the description of the structure of the layers, permeability coefficients, heat capacity and ...

Microlensing Detections of Moons of Exoplanets

, 2008
We investigate the characteristic of microlensing signals of Earth-like moons orbiting ice-giant planets. From this, we find that non-negligible satellite signals occur when the planet-moon separation is similar to or greater than the Einstein radius of ...
