Acid weathering of basalt and basaltic glass: 2. Effects of microscopic alteration textures on spectral properties
(Journal of Geophysical Research: Planets, 2017-01-24)
Acid alteration has long been proposed for the Martian surface, and so it is important to understand how the resulting alteration textures affect surface spectra. Two basaltic materials of varying crystallinity were altered ...
Diaspores and related hydroxides' Spectral-compositional properties and implications for Mars
(Journal of Geophysical Research, 2000-03-25)
Differences in spectral reflectance properties (0.3-26 μm) of a suite of metal hydroxides (gibbsite, böhmite, diaspore, goethite, and manganite) have been found to be a function of both structural and compositional differences ...
Pyroxene reflectance spectra: Minor absorption bands and effects of elemental substitutions
(Journal of Geophysical Research, 2002-06-13)
Reflectance spectra of a suite of compositionally diverse pyroxenes exhibit variable spectral properties which are associated with various elemental substitutions. Those associated with transition series elements, such as ...
More than Talking Heads?!? How do administrative tribunals hear from the public? A report prepared for the Consumers’ Association of Canada – Manitoba Branch
(2021-04-30)
Consumers and the general public want a say in the decisions which affect them. However, access to meaningful engagement in regulatory decisions is uneven across jurisdictions, as well as across types of tribunals. Scholarship ...
The ecology of methane in streams and rivers: patterns, controls, and global significance
(Ecological Society of America, 2015-12-07)
Streams and rivers can substantially modify organic carbon (OC) inputs from terrestrial landscapes, and much of this processing is the result of microbial respiration. While carbon dioxide (CO₂) is the major end‐product ...
Compositional homogeneity of CM parent bodies.
(The Astronomical Journal, 2016-08-10)
CM chondrites are the most common type of hydrated meteorites, making up ∼1.5% of all falls. Whereas most CM chondrites experienced only low-temperature (∼0°C–120°C) aqueous alteration, the existence of a small fraction ...
Spectroscopic approaches for studying faint text on a wooden tally from Invincible (1758)
(International Journal of Conservation Science, 2013-01-01)
In this study we describe the application of X-ray fluorescence, variable pressure scanning electron microscopy and visible (420-720 nm) hyperspectral imaging to assess the surface properties of a wood tally stick that was ...
Statement on Spectroscopic Imaging in Art Conservation: A New Tool for Materials Investigations
(Leonardo Electronic Archive, 2002-09)
Reenvisioning an Energy Strategy for Manitoba: Planning for 2030 and Beyond
(University of Winnipeg, 2020)
On March 10, 2020 the Re-envisioning an Energy Strategy for Manitoba: Planning for 2030 and Beyond workshop was held at The University of Winnipeg. The purpose of the event was to initiate a discussion amongst Manitobans ...
Calibrations of phase abundance, composition, and particle size distribution for olivine-orthopyroxene mixtures from reflectance spectra
(American Geophysical Union, 1986-10-10)
Spectral reflectance measurements of characterized (phase abundance, particle size) mixtures of olivine and orthopyroxene were utilized to define the correlations between spectral and albedo parameters of such assemblages ...
