Numerical simulation of elastic stress in the microstructure of snow [PDF]

Annals of Glaciology, 2004
AbstractThe mechanical properties of snow depend on its microstructure. The fabric of snow was reconstructed in three dimensions using serial sections or X-ray microtomography. A voxel-based finite-element model, with the elements based on the microstructure and ice as the material, was used to calculate the stress distribution in the snow.

Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Snow water equivalent retrieved from X- and dual Ku-band scatterometer measurements at Sodankylä using the Markov Chain Monte Carlo method [PDF]

The Cryosphere
Radar at high frequency is a promising technique for fine-resolution snow water equivalent (SWE) mapping. In this paper, we extend the Bayesian-based Algorithm for SWE Estimation (BASE) from passive to active microwave (AM) application and test it using ...

Predominance of Externally Mixed Black Carbon Over the Tibetan Plateau During the Asian Summer Monsoon

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The mixing state of black carbon (BC) strongly influences its lifetime and radiative forcing over the Tibetan Plateau (TP). Previous observations, mostly conducted during the non‐monsoon season, suggested that thickly coated BC dominates due to long‐range transport from South Asia.

Effect of snow microstructure variability on Ku-band radar snow water equivalent retrievals [PDF]

The Cryosphere, 2019
Abstract. Spatial variability in snowpack properties negatively impacts our capacity to make direct measurements of snow water equivalent (SWE) using satellites. A comprehensive data set of snow microstructure (94 profiles at 36 sites) and snow layer thickness (9000 vertical profiles across 9 trenches) collected over two winters at Trail Valley Creek ...

Presenting Snow Grain Size and Shape Distributions in Northern Canada Using a New Photographic Device Allowing 2D and 3D Representation of Snow Grains

Frontiers in Earth Science, 2020
Geophysical properties of snow are known to be sensitive to climate variability and are of primary importance for hydrological and climatological process simulations.

Study of a temperature gradient metamorphism of snow from 3-D images: time evolution of microstructures, physical properties and their associated anisotropy [PDF]

The Cryosphere, 2014
We carried out a study to monitor the time evolution of microstructural and physical properties of snow during temperature gradient metamorphism: a snow slab was subjected to a constant temperature gradient in the vertical direction for 3 weeks in a cold

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, Volume 68, Issue 5, Page 908-918, October 2026.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

The Genomic Landscape of Metallic Colour Variation in Ground Beetles

Molecular Ecology, Volume 35, Issue 20, October 2026.
ABSTRACT The metallic colour variation of beetles is a spectacular feature that has inspired diverse human cultures. However, little is known about the genetic basis of this trait or its ecological importance. In this study, we characterize the geographical distribution, optical mechanism, genetic basis and ecological and evolutionary importance of ...
