The Effects of air mass origin on cumulus clouds in the Caribbean

Creator:: Johnson, Kimberly
Abstract:: Knowledge concerning trade wind cumulus, one of the most dominant cloud types on the planet, has become increasingly important when considering global issues such as climate change due to their potential influence on the Earth’s energy budget. In this project, using data from the Rain in Cumulus over the Ocean...

⁴⁰Ar/³⁹Ar Ages and Trace Element Variations in Colombian Emeralds

Creator:: Svadlenak, Ellen
Abstract:: The Colombian emerald deposits are globally unique because they are hosted in hydrothermally altered black shales on either side of the Cordillera Oriental. We used electron microprobe analysis to study variations in trace element concentrations in transects across emeralds, and used the ⁴⁰Ar/³⁹Ar dating method to determine the age of...

A Model of Mesodinium Rubrum Blooms in the Columbia River Estuary

Creator:: Sherry, Elisabeth J.
Abstract:: Every year in the late summer, patches of the Columbia River estuary begin to turn red. These patches are blooms of mixotrophic ciliates (Myrionecta rubra or Mesodinium rubrum/major) (MR) that ingest the chloroplast of their prey, the cryptophytes (CR) Teleaulax amphioxeia (Peterson et al., 2013), and use the acquired organs...

Hydrogeography of Cloudburst Flooding in the Himalaya

Creator:: Michelsen, Sonja
Abstract:: Even though cloudburst events in high mountain areas can be highly destructive and result in significant losses of life, little is known definitively about these flood events. An exact understanding of the driving processes, typical precipitation rates, and impacts of cloudburst events remain uncertain. This study seeks to advance knowledge...

Metagenomics and metatranscriptomics of the leaf- and root-associated microbiomes of Zostera marina and Zostera japonica

Creator:: Wojahn, John Michael Adrian
Abstract:: A great deal of research has been focused on the microbiomes of terrestrial angiosperms (flowering plants), but much less research has been performed on the microbiomes of aquatic angiosperms (Turner et al. 2013). Eelgrass beds are extremely productive ecosystems that provide habitat for many marine organisms, such as fish, shellfish,...

A Comparative Analysis of Automated and Time-Integrated Sediment Samplers

Creator:: Babb, Arden I.
Abstract:: This study was conducted to determine if a time-integrated Phillips sampler was able to estimate sediment yield when compared to a reference produced by an automated sampler. Time-integrated samplers are easier to use, more cost effective, and can withstand storm events better than automated samplers, but are not designed to...

The Effects of Wildfire on Soil Hydraulic Properties in an Appalachian Hardwood Forest

Creator:: Ruud, Danica R.
Abstract:: Wildfires can affect soil physical properties, resulting in changes in infiltration, hillslope runoff, groundwater recharge, and sediment and dissolved nutrients to streams. In November 2016, the Chimney Tops 2 Fire burned 4,617 ha of Appalachian hardwood forest in eastern Tennessee. A portion of the fire burned through a National Ecological...

The Implementation of Passive RFID Tags to Sample Volumetric Water Content for an Autonomous Irrigation System

Creator:: Guo, Matthew D.
Abstract:: The agricultural industry in the Western United States continues to possess issues of overwatering, accounting for over 80% of consumed water per year in the country. While technologies such as satellite imaging and sensor networks have slowly improved irrigation Best Management Practices to reduce superfluous water consumption, limitations associated with...

Evaluation of a Variable Mixing Efficiency Parameterization on the Simulation of Last Glacial Maximum (LGM) Oceanic Circulation

Creator:: Thorstensson, Danil
Abstract:: This study tested the utility of a variable mixing efficiency formulation proposed by Mashayek, et al. (2017) for use in oceanographic models other than the modern, pre-industrial ocean. This formulation is used to calculate diapycnal (vertical) mixing due to unresolved subgrid-scale processes. Results from Last Glacial Maximum (LGM) simulations for...
