Journal ArticleDOI
Arctic Permafrost Active Layer Detachments Stimulate Microbial Activity and Degradation of Soil Organic Matter
TL;DR: It is indicated that ALDs may amplify climate change due to the release of labile SOM substrates from thawing High Arctic permafrost.
Journal ArticleDOI
Molecular characterization of dissolved organic matter in glacial ice: coupling natural abundance 1H NMR and fluorescence spectroscopy.
Brent G. Pautler,Gwen C. Woods,Ashley Dubnick,André J. Simpson,Martin Sharp,Sean J. Fitzsimons,Myrna J. Simpson +6 more
TL;DR: This study suggests that the bulk of the dissolved organic matter from these glaciers is a mixture of biologically labile molecules derived from microbes.
Journal ArticleDOI
Evidence for the enhanced lability of dissolved organic matter following permafrost slope disturbance in the Canadian High Arctic
Gwen C. Woods,Myrna J. Simpson,Brent G. Pautler,Scott F. Lamoureux,Melissa J. Lafrenière,André J. Simpson +5 more
TL;DR: In this article, passive samplers were placed throughout paired High Arctic watersheds during the duration of the 2008 spring flush in Nunavut, Canada and were analyzed for structural and spectral characteristics via NMR and fluorescence spectroscopy as well as vulnerability to degradation with simulated solar exposure.
Journal ArticleDOI
Synthesis and surface control of colloidal Cr3+-doped SnO2 transparent magnetic semiconductor nanocrystals.
TL;DR: The synthesis of colloidal Cr(3+)-doped SnO(2) nanocrystals prepared under mild conditions via a hydrolysis method is described and it is shown by means of nanocrystal surface ligand exchange that even under mild reaction conditions a significant fraction of the dopant ions reside on the Nanocrystal surfaces.
Journal ArticleDOI
Detection and structural identification of dissolved organic matter in Antarctic glacial ice at natural abundance by SPR-W5-WATERGATE 1H NMR spectroscopy.
Brent G. Pautler,André J. Simpson,Myrna J. Simpson,Li-Hong Tseng,Manfred Spraul,Ashley Dubnick,Martin Sharp,Sean J. Fitzsimons +7 more
TL;DR: The detection of free amino acid and amino sugar monomer components of peptidoglycan within the ice suggests that Antarctic glacial DOM likely originates from in situ microbial activity, which may result in a flux of nutrients into adjacent ecosystems.
