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 ...
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 ...
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 ...
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 ...
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 ...
Differences in ebullitive methane release from small, shallow ponds present challenges for scaling
(Elsevier B.V., 2022)
Small, shallow waterbodies are potentially important sites of greenhouse gas release to the atmosphere. The role of ebullition may be enhanced here relative to larger and deeper systems, due to their shallow water, but ...
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 ...
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 ...
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, ...
