Evidence of a Glacier-like Movement amongst Snow Particles

Snow Avalanches, Ice Avalanches and Glacier Surges

Virus-like particles in cystic mammary adenoma of a snow leopard.

Virus-like particles were observed in the giant cells of a mammary adenoma of a snow leopard kept in captivity. Particles that measured 115 to 125 nm in diameter budded from the lamella of endoplasmic reticulum and were studded on their inner surfaces with dense granules (approximately 12 nm) that gave them their unique ultrastructural morphology. Such particles were not observed extracellularl...

Snow Mapping of Alamchal Glacier Using Remote Sensing Data

Detection and determination of ice and snow characteristics using remote sensing data is a new method in obtaining hydrology parameters. In order to determine these characteristics the numbers of meteorological stations are not enough in the glacier and mountain regions. We suggest using remotely sensing data for removing these deficiencies. Snow is distinguished more than other objects in the ...

The search for seismic signatures of movement at the glacier bed in a polythermal valley glacier

A passive seismology experiment was conducted across the main overdeepening of Storglaciären in the Tarfala valley, northern Sweden, to investigate the spatial and temporal distribution of basal microseismic waveforms in relation to known dynamics of this small polythermal sub-arctic glacier. The high ablation rate made it difficult to keep geophones buried and well coupled to the glacier durin...

Measuring Snow and Glacier Ice Properties from Satellite

Satellite remote sensing is a convenient tool for studying snow and glacier ice, allowing us to conduct research over large and otherwise inaccessible areas. This paper reviews various methods for measuring snow and glacier ice properties with satellite remote sensing. These methods have been improving with the use of new satellite sensors, like the synthetic aperture radar (SAR) during the las...
