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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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.
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 ...
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 ...
