Linking dominant rainfall-runoff event hydrologic response dynamics with nitrate and chloride load estimates of three boreal Shield catchments
(American Geophysical Union, 2021-08-21)Understanding hydrological dynamics in boreal Shield catchments is critical for projecting changes in stream runoff and chemistry in a region that is sensitive to climate change. Previous work has mostly focused on a limited ... -
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 ... -
Intra-urban analysis of commercial locations: A GIS-based approach
(2013)The urban landscape is an interspersed mixing of residences, shops, theatres, parks, natural areas, and a multitude of other uses. From the early days of the central markets, to the planned downtown, to the heavily planned ... -
The role of wetland coverage within the near-stream zone in predicting of seasonal stream export chemistry from forested headwater catchments
(John Wiley & Sons Ltd., 2019-02-19)Stream chemistry is often used to infer catchment‐scale biogeochemical processes. However, biogeochemical cycling in the near‐stream zone or hydrologically‐connected areas may exert a stronger influence on stream chemistry ... -
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 ... -
Snow covered soils produce N₂O that is lost from forested catchments prior to snowmelt
(American Geophysical Union, 2016-08-25)The magnitude of net soil nitrous oxide (N₂O) production from a snow‐covered catchment in a northern temperate forest was investigated. There was considerable net soil N₂O‐N production and consumption through the snowpack, ... -
A model for training undergraduate students in collaborative science
(American Geophysical Union, 2018-08-16)Engagement of undergraduate students in research has been demonstrated to correlate with improved academic performance and retention. Research experience confers many benefits on participants, particularly foundational ... -
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. -

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 ... -
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 spectroscopy revisited: Spectral-compositional correlations and relationship to geothermometry.
(Journal of Geophysical Research, 1991-12-25)Pyroxene reflectance and transmittance spectra have been examined in a search for systematic relationships between spectral features and compositional variations and to assess the applicability of reflectance spectroscopy ... -
Manganese-rich olivines: Identification from spectral reflectance properties
(Journal of Geophysical Research, 1997-11-25)Reflectance spectra of manganese-rich olivines were examined to determine which spectral features allow these minerals to be distinguished from forsteritic-fayalitic olivines. The results indicate that manganese-rich ... -
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 ... -

Mineralogic constraints on sulfur-rich soils from Pancam spectra at Gusev crater, Mars
(Geophysical Research Letters, 2007-07-06)The Mars Exploration Rover (MER) Spirit excavated sulfur-rich soils exhibiting high albedo and relatively white to yellow colors at three main locations on and south of Husband Hill in Gusev crater, Mars. The multispectral ... -
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 ... -
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 ... -
Optical and radiometric models of the NOMAD instrument part I: the UVIS channel
(Optics Express, 2015-11-09)The NOMAD instrument has been designed to best fulfil the science objectives of the ExoMars Trace Gas Orbiter mission that will be launched in 2016. The instrument is a combination of three channels that cover the UV, ...
