Nitrogen and phosphorus loads to temperate seepage lakes associated with allochthonous dissolved organic carbon loads
(American Geophysical Union, 2018-06-16)
Terrestrial loads of dissolved organic matter (DOM) have increased in recent years in many north temperate lakes. While much of the focus on the “browning” phenomena has been on its consequences for carbon cycling, much ...
Imaging spectroscopy of geological samples and outcrops: Novel insights from microns to meters
(GSA Today, 2015-12-01)
Imaging spectroscopy is a powerful, non-destructive mineralogic tool that provides insights into a variety of geological processes. This remote measurement technique has been used for decades from orbital or aerial platforms ...
Framing Indigenous Partnerships in Energy and Allied Renewable Resource Sectors. Final Report to the Social Sciences and Humanities Research Council of Canada
(2017)
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 ...
Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission
(Geophysical Research Letters, 2017-04-22)
Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of the lunar surface. Spectra measured in situ by the visible-near-infrared spectrometer (VNIS) on board the ...
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 ...
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 ...
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 ...
Physical characterization of ~2 m diameter near-Earth asteroid 2015 TC25: A possible boulder from E-type asteroid (44) Nysa
(The Astronomical Journal, 2016-11-11)
Small near-Earth asteroids (NEAs) (<20 m) are interesting, because they are progenitors for meteorites in our terrestrial collection. The physical characteristics of these small NEAs are crucial to our understanding of the ...
Summer storms trigger soil N₂O efflux episodes in forested catchments
(American Geophysical Union, 2016-01-14)
Climate change and climate-driven feedbacks on catchment hydrology and biogeochemistry have the potential to alter the aquatic versus atmospheric fate of nitrogen (N) in forests. This study investigated the hypothesis that ...
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 ...
