Terrestrial Mercury Cycling in Northern Michigan: Honeysuckle Creek Watershed and Burt Lake (thesis)
Mercury (Hg), a potent environmental toxicant, affects the cognition and health of both human and aquatic ecosystem populations. Despite regulation-driven decreases in atmospheric mercury levels, Burt Lake is among the ...
Kink-Band and Velocity-Boundary Interference (thesis)
The established techniques for constructing and restoring balanced cross sections using flexural slip work well for modeling simple faults and folds, but these methods show weaknesses when applied to more complicated ...
δ13C and δ18O Analyses of Carbonate Concretions and Nodules and the Evidence for a Cretaceous Greenhouse (thesis)
The Aptian-Albian Torok Formation and Nanushuk Formation rocks of Slope Mountain, also known as the Marmot Syncline, have been interpreted to represent shallow marine, deltaic, and fluvial depositional environments. ...
Influence of the Kingak Formation Ultimate Shelf Margin on Frontal Structures of the Brooks Range in National Petroleum Reserve - Alaska (thesis)
Well and seismic data in the National Petroleum Reserve in Alaska (NPRA) demonstrate that the Jurassic—Lower Cretaceous Kingak Shale is present throughout NPRA. Several southward progradational depositional sequences within ...
The Removal of the Jordan's Point Dam: Examining Channel Restructure and Sediment Mobilization (thesis)
The 2019 removal of the Jordan's Point Dam, a low-head concrete structure built in 1911 but predated by several older crib dams, is understood to have served as a significant
geomorphological event in the Maury River. ...
Assessing the Impact of Soil on Manganese Contamination in Springs and Groundwater in the Shenandoah Valley, Virginia (thesis)
A substantial fraction of the Shenandoah Valley, VA population relies on ground and spring water for domestic use. Manganese (Mn) is of particular concern in groundwater, as low-level
chronic exposure to aqueous Mn ...
Analyzing the Relationships Between Aqueous Manganese and Geological Factors in Groundwater in the Shenandoah Valley (thesis)
Manganese (Mn) can be either harmful or beneficial to human health, depending on the phase and concentration that the element is found in. In recent years research has indicated that low level chronic exposure to aqueous ...
