Observations of Sun-Induced Chlorophyll fluorescence (SIF), Photochemical Reflectance Index (PRI) and Chlorophyll:Carotenoid Index (CCI) during spring recovery in two evergreen conifers from the Boreal Forest.
DownloadFall 2022
Northern hemisphere evergreen forests assimilate a significant fraction of global atmospheric CO2. Conifers undergo winter-downregulated photosynthetic activity and spring-onset photosynthetic activation. Currently, increased temperatures are leading to shifts in photosynthetic phenology (early...

Raman Spectroscopic Properties of Aqueous Chloride Salt Solutions: Chlorides of Alkalis, Alkaline Earths and First-Row Transition Metals
DownloadFall 2022
Saline aqueous fluids play numerous key roles in many geologic processes, but how fluids flow and interact with rocks depends on their physical and chemical properties, which in turn depend on the types, concentrations, and speciation of solutes. Raman spectroscopy is a powerful tool to identify...

Water and Fine-grained Sediment Assessment in the Capital Region (Edmonton) of the North Saskatchewan River (Canada)
DownloadFall 2022
Purpose: To better understand the behaviors of sediment-associated metals (Cu, Ni, Cd, Mn, Cr, Pb, Fe, Sr, Mo, and Co), an evaluation of physicochemical parameters and metal speciation on suspended and bedload sediment collected from the North Saskatchewan River was conducted in 2018. Sampling...

Fall 2022
The thermohaline intrusion of the warm and saline Atlantic Water (AW) into the Arctic Ocean, referred to as “Arctic Atlantification”, has significant implications and feedback on the {thermo}dynamics of the Arctic Ocean. The AW enters the Arctic Ocean through two gateways: Fram Strait and the...

Precious metal, Lu-Hf, and Re-Os geochemistry of the metasomatized lithospheric mantle: implications for subcrustal precious metal mobilization and MARID petrogenesis
DownloadFall 2022
The connection between metasomatism - the change in chemical composition of a rock via interaction with a fluid or melt - and the formation of metalliferous ore deposits in the Earth’s crust is well established. Similarly, it is now accepted that the Earth’s lithospheric mantle has experienced...

Tracing Organic Contamination from Collection to Curation: Contamination Mitigation of Meteorites and Implications for Advanced Curation Methods of Astromaterials
DownloadFall 2022
Meteorites are the most primitive materials in the solar system and can provide important information about the early earth, planetary processes, and possibly yield insights to the building blocks of life. All meteoritic astromaterials are exposed to both organic compound and microbial...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Sedimentological, Ichnological, and Architectural Characteristics of Geobodies in a Fluvial to Estuary Setting: the McMurray Formation in the Christina River area, NE Alberta, Canada
DownloadSpring 2023
The Lower Cretaceous McMurray Formation is the primary host of the crude bitumen reserves in the Athabasca Oils Sand Region. The regionally extensive meander belts associated with estuary point bars have been recognized as the primary reservoir facies in the McMurray Formation. It is widely...
