Buskirk, Reid Ezekiel (2021-12-16)The coupled processes of biogeochemical and hydrological processes in hyporheic zones (HZ) commonly determine the fate of contaminants in both groundwater and surface water. Many parts of the HZ experience both transient ...
-
Hofig, Daianne F (2021-03-22)Lacustrine varved sediments are high-resolution paleoenvironmental archives, in which their layers function as temporal markers of seasonality. The temporal framework of such records is required to improve benchmark climate ...
-
Price, Amy Elizabeth (2016-12-02)The local, highly mineralized geology, along with years of mining and improper disposal of the tailings and acid-mine drainage have degraded the quality of surface water within the San Juan Mountains, specifically, the ...
-
Litt, Joshua (2014-04-29)Red Mountain Creek is located in the rich mineralized San Juan Mountains of Southwestern Colorado, where mining from the mid 1800s through the late 1970s occurred. Sampling of the Uncompahgre River in the late 1970s, which ...

Barium Concentrations as a Proxy for Equatorial Pacific Productivity during the Past 140,000 Years Olaniyi-Sholanke, Oluwaseyifunmitan Modupeoluwa (2016-07-15)The accumulation of biogenic sediments in the deep ocean may yield important information about past ocean productivity and its relationship to climate change. Sediments, sampled at approximately millennial resolution, every ...

Maulana, Ivan (2016-01-15)The Ocean Anoxic Event 2 (OAE-2) at the Cenomanian-Turonian boundary is recognized from a carbon isotope excursion (CIE) in the Eagle Ford (EF) Group, and commonly attributed to global anoxic conditions in deeper marine ...
-
Jensen, Laramie Thaniel (2020-07-22)The Arctic Ocean is characterized by broad continental shelves, large river inputs, sea ice coverage, and limited exchange with other major ocean basins. This provides a unique environment in which to examine the distribution ...
-
McBee, Jayme M (2014-01-08)Isotopic composition and concentrations of Pb are used to identify sources of anthropogenic and natural Pb and to assess Pb bioavailability in soils and native plants at a former military installation that served as a ...
-
Weinlein, William (2012-10-19)Previous studies showed that sea surface salinity (SSS) in the Florida Straits as well as Florida Current transport covaried with changes in North Atlantic climate over the past two millennia. However, little is known about ...
-
Lee, Adam Allen (2017-02-15)Rivers and streams develop landform morphology in equilibrium with the flow of water and sediment through the channel. This dissertation examines features in fluvial systems with different geomorphic regimes; step-pool ...
-
Laird, Edward Dylan (2016-07-27)Wastewater treatment plants (WWTP) are typically incapable of addressing the influx of antibiotics (AB), and may act as a harbor for the selection and proliferation of antibiotic resistant bacteria (ARB). In order to examine ...
-
McCreary, Molly Elizabeth (2022-08-11)The Austin Group, comprised of chalk and marly chalk, is a classic fractured chalk play, that has seen a renaissance as an unconventional reservoir exploited by the combination of fracking and horizontal drilling across ...
-
Scherer, John Andrew (2021-12-06)This study demonstrates a comparison of a High-Resolution Gas Chromatography (HRGC) analysis of drilling cuttings and sidewall cores from the same oil well, with the purpose of determining how well the two sample types are ...
-
Hostak, Ryan Michael (2019-04-05)Ventilation of carbon stored in the deep ocean is thought to play an important role in atmospheric COv2 increases associated with the Pleistocene deglaciations. The presence of this respired carbon has been recorded by an ...
-
Loveley, Matthew Robert (2017-07-31)The objective of this dissertation is to understand the dynamics of U-Th isotope behavior in deep sea marine sediment cores extracted from the Panama Basin located in the eastern Equatorial Pacific. Specifically, I attempt ...

Deciphering Equatorial Pacific Deep-Sea Sediment Transport Regimes by Core-Log-Seismic Integration Ortiz, Estefania (2018-06-13)Understanding deep-sea sediment transportation and deposition regimes is a key to accurately evaluate paleoceanographic implications recorded by pelagic sediments. However, investigating the movement of deep-sea pelagic ...
-
Franklin, Alyssa L. (2010-07-14)The relationship between intermediate watermass response to Atlantic Meridonial Overturning Circulation (AMOC) during two abrupt cooling events of the last deglacial, the Younger Dryas (YD) and Heinrich Event 1 (H1) is c ...
-
Lopez, Grecia Ivonne (2015-08-10)The goals of this thesis are to assess the distribution of 230Th and 232Th along a latitudinal gradient in the Central Equatorial Pacific Ocean (~155° W - 159°W) at two sites: 8°N and the equator. In so doing, I test for ...

Schmitt, Hailey Nicole (2023-11-28)In the Gulf Coast Aquifer (GCA) in Texas, arsenic (As), fluoride (F), and nitrate (NO3) concentrations are spatially variable, and in certain areas, frequently exceed drinking water guidelines. Understanding the sources ...
