Heat Flow from a Vapor-Dominated Sublacustrine Vent Field Beneath Yellowstone Lake

Creator:: Favorito, Julia E.
Abstract:: Portions of Yellowstone Lake sit on top of a vigorous but not well understood hydrothermal system situated in a region of intense geologic and environmental forcings. A heat flow study conducted over the Stevenson Island Vent Field (SIVF), a vent field at the bottom of Yellowstone Lake underlain by an...

Incorporating User Feedback into Machine Learning Systems

Creator:: Das, Shubhomoy
Abstract:: Although machine learning systems are often effective in real-world applications, there are situations in which they can be even better when provided with some degree of end user feedback. This is especially true when the machine learning system needs to customize itself to the end user's preferences, such as in...

Simulator-Defined MDP Planning with Applications in Natural Resource Management

Creator:: Alkaee Taleghan, Majid
Abstract:: This work is inspired by problems in natural resource management centered on the challenge of invasive species. Computing optimal management policies for maintaining ecosystem sustainable is challenging. Many ecosystem management problems can be formulated as MDP (Markov Decision Process) planning problems. In a simulator-defined MDP, the Markovian dynamics and rewards...

Overwintering of Erysiphe necator and Inoculum Monitoring for Decision Aids

Creator:: Thiessen, Lindsey D.
Abstract:: Grape powdery mildew (Erysiphe necator) causes economic damages to grape worldwide due to the cost of management and injury to berries. Each region where European grapevine (Vitis vinifera) is grown experiences a unique epidemic, and disease prediction models that are based on empirical correlations of weather data to disease fail...

Volatile mobility of trace metals in volcanic systems

Creator:: Loewen, Matthew W.
Abstract:: Semi-volatile trace metals like Li, Cu, Mo, Sn, In, and Pb have the potential to track mobility of a volatile phase in volcanic systems. In this dissertation four studies are presented that either directly investigate or are motivated by observations of trace metal behavior in volcanic systems. A common tool...

The Egan Range volcanic complex : implications for the evolution of a mid-tertiary synextensional volcanic system

Creator:: Feeley, Todd C.
Resource Type:: Masters Thesis

Structure of the crust beneath Lake Superior from forward modeling of large aperture seismic data

Creator:: Shay, John T.
Abstract:: Both travel times and amplitudes of large offset refracted and reflected arrivals observed during GLIMPCE (Great Lakes International Multidisciplinary Program on Crustal Evolution) along line A in Lake Superior have been modeled using two-dimensional ray tracing techniques. Forward modeling was used to iteratively refine an initial velocity model that was...

Petrology of the reversely zoned Mickey Pass Tuff, west-central Nevada

Creator:: Templeton, Jeffrey H.
Resource Type:: Dissertation

Reactive transport modeling in a discrete fracture : applications to the formation of sericitic hydrothermal alteration at Butte, Montana

Creator:: Geiger, Sebastian
Abstract:: A model for the spatial and temporal evolution of the gray sericitic (GS) and sericite with remnant biotite (SBr) hydrothermal alteration selvages within the Butte Quartz Monzonite (BQM) of the porphyry copper deposit at Butte, Montana, is presented. The model provides a mathematical description for the location and advance of...

The genesis of the San Vicente lead zinc rhythmite deposit, Peru : a petrologic, geochemical, and sulfur isotope study

Creator:: Schütfort, Erwin G.
Abstract:: The San Vicente zinc lead deposit is located in the Eastern Andes of Central Peru. The deposit is an epigenetic Mississippi Valley-type deposit based on stratigraphic, geologic, petrographic, and geochemical evidence. The dolomite host rocks of the Pucara Group are of Triassic-Jurassic age. The source of metals are red sandstones...
