Methylmercury production and export across the terrestrial-aquatic continuum in permafrost peatland catchments
DownloadFall 2023
Ongoing permafrost thaw in northern peatland catchments may increase the production and downstream delivery of neurotoxic methylmercury (MeHg) across the terrestrial-aquatic continuum. Peatlands in boreal-Arctic regions have large stocks of mercury (Hg) in frozen soils, accumulated through...

Fall 2013
Aryl hydrocarbon receptor (AhR) ligands such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and metals, such as mercury (Hg), are environmental co-contaminants with multiple biological consequences. Therefore, the objectives of the current dissertation were to: 1) examine the potential effect of...

Spring 2010
Human activities have profoundly altered the biogeochemical cycle of many elements including mercury (Hg). Since ~1850 AD, industrial processes are suggested to have led to a 3-fold increase in Hg deposition above natural, pre-industrial levels. Despite extensive historical evidence for...

Records of atmospheric mercury deposition and post-depositional mobility in peat permafrost archives from central and northern Yukon, Canada
DownloadFall 2017
Environmental archives provide a feasible means for studying the biogeochemical cycling of heavy metals including mercury (Hg). Although many temperate peat bogs have been successfully used to reconstruct natural and anthropogenic atmospheric Hg deposition fluxes, northern circumpolar permafrost...

Soil and porewater chemistry from peatlands of the Interior Plains, northwestern Canada
2022-11-09
Thompson, L. M., Olefeldt, D., Mangal, V., Knorr, K.H.
The xlsx files contain one "ReadMe" tab and one "Data" tab regarding the chemistry of peatland soils or porewater. The "ReadMe" tab details the variable name, units, description, citation (optional), laboratory, and vocabulary terms. The "Data" tab contains data collected from twelve wetlands...

Fall 2010
As Mercury orbits the Sun, solar induced gravitational torques give rise to a planetary libration. While undergoing this 88 day period libration, the axes of minimum moment of inertia of the mantle and solid core, if present, become misaligned, leading to a gravitational torque which initiates a...
