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 ...
Lake Manitoba and its Watershed: Knowledge Gaps & Next Steps
(2016)
Lake Manitoba is a large, shallow prairie lake located in central Manitoba. The lake and watershed are subject to numerous environmental pressures including climate change, land use change, and regulation of water levels, ...
Acidic weathering of basalt and basaltic glass: 1. Near-infrared spectra, thermal infrared spectra, and implications for Mars
(Journal of Geophysical Research: Planets, 2017-01-24)
Acid-leached rinds and coatings occur in volcanic environments on Earth and have been
identified using orbital spectroscopy on Mars, but their development is poorly understood. We simulated long-term open-system acidic ...
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, ...
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 ...
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 ...
Visible/near-infrared spectral diversity from in situ observations of the Bagnold Dune Field sands in Gale Crater, Mars
(Journal of Geophysical Research: Planets, 2017-12-13)
As part of the Bagnold Dune campaign conducted by Mars Science Laboratory rover Curiosity, visible/near-infrared reflectance spectra of dune sands were acquired using Mast Camera (Mastcam) multispectral imaging (445–1013 ...
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 ...
