Xunaa Shuká HíT, The Tribal House, In Glacier Bay National Park And Preserve, Alaska, Emiko Furuya
Arctic and Northern Studies
This research analyzes the Tribal House project in Glacier Bay National Park and Preserve in Southeast Alaska, which the Hoonah Indian Association (the tribal government at Hoonah) and Glacier Bay National Park and Preserve have promoted collaboratively. The Tribal House project is the construction of an indigenous structure in Glacier Bay National Park and Preserve, primarily for the use of Hoonah, the local Tlingit community. This research investigates the motivations of the partners in supporting the project. It concludes that the two partners' motivations, which derive from distinct missions, reconcile with one another in a complex way. The Hoonah Indian …
Modeling The Injection Of Co₂-N₂ In Gas Hydrates To Recover Methane Using Cmg Stars, Shruti Oza
Modeling The Injection Of Co₂-N₂ In Gas Hydrates To Recover Methane Using Cmg Stars, Shruti Oza
Engineering
The objective of this project was to develop a reservoir simulation model using CMG STARS for gas hydrates to simulate the Ignik Sikumi#1 field trial performed by ConocoPhillips at the North Slope, Alaska in 2013. The modeling efforts were focused exclusively on the injection of CO₂-N₂ in gas hydrate deposits to recover methane after an endothermic reaction. The model was history matched with the available production data from the field trial. Sensitivity analysis on hydrate saturation, intrinsic permeability, relative permeability curves, and hydrate zone size was done to determine the impact on the production. This was followed by checking the …
Genetic Population Structure And Dynamics Of Nearctic Bering Cisco And Applied Mixed-Stock Analysis Of The Yukon River Commercial Fishery, Ora L. Russ
Theses and Dissertations
Bering cisco (Coregonus laurettae) are anadromous salmonids with only three known spawning populations located in the Yukon, Kuskokwim, and Susitna river drainages, respectively in Alaska. Bering cisco are actively harvested in both subsistence and commercial fisheries in Alaska. The work presented herein was a genetic study conducted on Bering cisco with three main objectives: 1) to develop genetic markers for Bering cisco; 2) to evaluate the population structure of the Yukon, Kuskokwim, and Susitna spawning aggregations and 3) to use genetic mixed-stock analysis to estimate the contributions of baseline cisco populations to the Yukon Delta commercial harvest during 2010, 2011, …
Constraints On The Structure Of The Border Ranges Fault System, South-Central Alaska From Integrated 3d Inversion Of Gravity/Magnetic Data, Niti Mankhemthong
Constraints On The Structure Of The Border Ranges Fault System, South-Central Alaska From Integrated 3d Inversion Of Gravity/Magnetic Data, Niti Mankhemthong
Open Access Theses & Dissertations
I use updated gravity data, available aeromagnetic data, and other geophysical information as constraints to develop 2D and 3D structural models of density and magnetic susceptibility to better locate and determine the shape of the Border Ranges fault system (BRFS), the Border Range ultramafic and mafic assemblages and other forearc-arc boundary structures in south-central Alaska, that have previously been studied in only limited detail. There are three geophysical research projects that form the chapters of the dissertation. First, I estimated near-surface density variations in the central Kenai Peninsula based on the adaptation of the Nettleton (1939)-Parasnis (1952) method using Tarantola …
Provenance Signature Of A Forearc Basin Modified By Spreading Ridge Subduction: Detrital Zircon Geochronology And Detrital Modes From The Paleogene Arkose Ridge Formation, Southern Alaska, Cullen Kortyna
Honors Theses
Upper Paleocene–Eocene boulder conglomerate, cross-stratified sandstone, and laminated carbonaceous mudstone of the Arkose Ridge Formation exposed in the southern Talkeetna Mountains record fluvial-lacustrine deposition proximal to the volcanic arc in a forearc basin modified by Paleogene spreading ridge subduction beneath southern Alaska. U-Pb ages of detrital zircon grains and modal analyses were obtained from stratigraphic sections spanning the 2,000 m thick Arkose Ridge Formation in order to constrain the lithology, age, and location of sediment sources that provided detritus. Detrital modes from 24 conglomerate beds and 54 sandstone thin sections aredominated by plutonic and volcanic clasts and plagioclase feldspar with …
Geologic Setting Of The Central Alaskan Hot Springs Belt: Implications For Geothermal Resource Capacity And Sustainable Energy Production, Amanda M. Kolker
Geologic Setting Of The Central Alaskan Hot Springs Belt: Implications For Geothermal Resource Capacity And Sustainable Energy Production, Amanda M. Kolker
Geosciences
The Central Alaskan Hot Springs Belt (CAHSB) is a vast stretch of low-temperature hydrothermal systems that has the potential to be a geothermal energy resource for remote communities in Alaska. Little exploration has occurred in the CAHSB and the resource is poorly understood. A geothermal power plant was installed in 2006 at Chena Hot Springs (CHS), one of the 30-plus hot springs in the CAHSB. This, in addition to the multiple direct use projects at CHS, could serve as a model for geothermal development elsewhere in the CAHSB. This dissertation evaluates the geologic setting of the CAHSB and explores the …

Concentrations of total Hg, Hg(II), and methylmercury were measured in stream-sediment, stream-water, and fish collected downstream from abandoned mercury mines in southwestern Alaska to evaluate environmental effects to surrounding ecosystems. These mines are found in a broad belt covering several tens of thousands of square kilometers, primarily in the Kuskokwim River basin. Mercury ore is dominantly cinnabar (HgS), but elemental mercury (Hg °) is present in ore at one mine and near retorts and in streams at several mine sites. Approximately 1400 t of mercury have been produced from the region, which is approximately 99% of all mercury produced from …

Geology And Ore Deposits Of The Salt Chuck-Rush And Brown Mine Area Prince Of Wales Island, Alaska, Judson H. Whitman
Geology And Ore Deposits Of The Salt Chuck-Rush And Brown Mine Area Prince Of Wales Island, Alaska, Judson H. Whitman
Bachelors Theses and Reports, 1928 - 1970
The Salt Chuck, Rush and Brown, and adjacent mines and claims form an area of approximately 15 square miles near the head of Kasaan Bay about 10 miles northwest of the village of Kasaan on Prince of Wales Island in southeastern Alaska. It is an area of moderate relief in which the hills rise from the water’s edge to heights of some 500 feet. Most of the area is covered with dense vegetation and muskeg.
