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 ...
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 ...
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 ...
Surface albedo and spectral variability of Ceres
(The Astrophysical Journal Letters, 2016-01-29)
Previous observations suggested that Ceres has active, but possibly sporadic, water outgassing as well as possibly varying spectral characteristics over a timescale of months. We used all available data of Ceres collected ...
Small-scale methane dispersion modelling for possible plume sources on the surface of Mars
(Geophysical Research Letters, 2012-10-11)
Intense interest in the characteristics of a methane source on Mars has been spurred by recent observations of a plume structure. The current NASA Mars Science Laboratory and future landers and orbiters will be tasked with ...
