Statement on Spectroscopic Imaging in Art Conservation: A New Tool for Materials Investigations
(Leonardo Electronic Archive, 2002-09)
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 ...
Evolution of Occator Crater on (1) Ceres
(The Astronomical Journal, 2017-02-17)
The dwarf planet Ceres (diameter 939 km) is the largest object in the main asteroid belt. Recent investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body which ...
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 ...
A chrono-geographic look at Mesolithic burials: an initial study
(Landesamt für Denkmalpflege und Archäologie Sachsen-Anhalt, 2016)
Over the past decade we have focused on two interrelated topics within Mesolithic burial studies, the relationship between burial number and burial date, and the chronology of Mesolithic sites with burials. Related to this ...
Framing Indigenous Partnerships in Energy and Allied Renewable Resource Sectors. Final Report to the Social Sciences and Humanities Research Council of Canada
Canada is a top five global energy producer and thus is in a leadership position with respect to how it engages in international markets and, increasingly, energy partnerships. Growing global energy demand and international ...
Isotopic reconstruction of the weaning process in the archaeological population of Canímar Abajo, Cuba: A Bayesian probabilities mixing models approach
(Public Library of Science, 2017-05-01)
The general lack of well-preserved juvenile skeletal remains from Caribbean archaeological sites has, in the past, prevented evaluations of juvenile dietary changes. Canímar Abajo (Cuba), with a large number of well-preserved ...
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 ...
