A Case Study of Solar Warming and Subsequent Mixing in the Arctic Upper Ocean for the 2011 Spring-Summer Transition

Creator:: Lee, Ara
Abstract:: Autonomous buoys were deployed in 2011 in the central Arctic: An Ice-Tethered Profiler (ITP) and Ice Mass Balance (IMB) buoys were deployed in the Makarov basin; a Polar Ocean Profiling System (POPS) and Ice Thickness (Ice-T) buoy were deployed on the Eurasian Basin. The two different sites were approximately 70km...

The Heart Beat of the Megafloods

Creator:: Valdez Hernandez, Saray
Abstract:: Marine sediment core OC1706B-02J ( 46° 15.4178 N, 125° 42.4543 W, at water depth 2263m), was collected on the lower continental slope near the base of the Willapa Canyon. It is a rapidly accumulating site (~30cm/kyr) located near the thrust front of the Cascadia Subduction Zone. The site is also...

Freeze-thaw cycles in permafrost soils and their impacts on the climate: A literature review

Creator:: Bergmann, Maya K.
Abstract:: Climate change is occurring at an increasingly rapid rate, with impacts heightened in the cold regions of the world including the Arctic. Warming effects are widespread, with one impacted process – freeze-thaw cycles – increasing in frequency and potentially triggering additional changes in permafrost soils that have previously acted as...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

Atmospheric nitrous oxide in the pre-800 ka atmosphere from ice cores from the Allan Hills, Antarctica

Creator:: Stock, Marika P.
Abstract:: Nitrous oxide is an important greenhouse gas that has both natural and anthropogenic sources in the modern atmosphere (Ciais et al., 2013). This project expanded the knowledge of the history of atmospheric N2O in the geologic past by measuring N2O concentrations in air trapped in very old polar ice. A...

The Usefulness of Stable Water Isotopes in Improving Drought Prediction

Creator:: Adams, Logan
Abstract:: Drought represents an import part of natural hydrologic cycles that govern the rate and transportation of water on global and regional scales. (Trenberth, et al. 2015) Agriculturally, drought represents a threat to crop production and can endanger political and economic stability through the loss of resources and the threat of...

Low-frequency Teleseismic and Infrasound Arrivals along the Dense Corvallis Nodal Array

Creator:: Way, Rachel
Abstract:: The dense Corvallis array deployed in January of 2022 aided in the high-resolution study of local geology. This array was made of 177 SmartSolo 3-component 5 Hz geophones around Corvallis, with a 93 geophone profile going west towards Bald Hill for approximately 5 km at an average of 64 m...

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...

Interannual variability of oceanographic conditions on the continental shelf outside of Sermilik Fjord

Creator:: Glickman, Abbie A.
Abstract:: Freshwater flux from the Greenland Ice Sheet has the capacity to affect regional and global circulation as well as contribute to sea level rise. Outlet glaciers are an important part of this process. They provide pathways for inland glaciers and ice sheets to melt and drain into the surrounding oceans....

Timing of Volcanism in Central Oregon: Dating Tam McArthur Rim Volcano

Creator:: Landoni, Katherine G.
Abstract:: The Tam McArthur Rim is a volcanic center located within the Tumalo Volcanic Field (TVF), approximately 25 km west of Bend, OR. The rim comprises of shallowly dipping bedded sequences of intermediate and silicic flows with minor tephra interbedding capped by a rhyodacite dome. Glacial activity has exposed significant portions...
