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 ...
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 ...
Distribution of hydrated minerals in the north polar region of Mars
(Journal of Geophysical Research, 2009-01-28)
The previous discovery of extensive deposits of hydrated minerals in Olympia Planum in the north polar region of Mars by the Mars Express OMEGA instrument raises important questions about the origin and subsequent ...
Composition of Jupiter irregular satellites sheds light on their origin
(EDP Sciences, 2017)
Context. Irregular satellites of Jupiter with their highly eccentric, inclined and distant orbits suggest that their capture took place after the giant planet migration. Aims. We aim to improve our understanding of the ...
Aboriginal Capacity Building Achievements for Sustainable Natural Resource Development
(Centre for Forest Interdisciplinary Research, University of Winnipeg, 2016)
This knowledge synthesis report provides the first bibliometric profile and systemic review of research on Aboriginal capacity building for natural resource development in Canada.
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 ...
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 ...
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 ...
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 ...
