Marine Heatwaves Influence Depth Preferences of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:

Teahan, Andrew

Abstract:

Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

Decoding DOM Degradation with Metatranscriptomics : How Do Sunlight and Microbial Communities Interact to Degrade Dissolved Organic Matter in Arctic Freshwaters?

Creator:

Nalven, Sarah G.

Abstract:

Arctic soils are warming, making vast stores of organic carbon available for conversion to CO₂. This could create a positive feedback loop and accelerate global warming, but the processes that convert this carbon into CO₂ are not well understood. We investigated how the combined activities of sunlight and microbes degrade...

Petrologic Investigations into the Magmatic Processes That lead to Au, Ag, and Base Metal Fertility: Insights from Pebble, Alaska and the Emigrant Pass Volcanic Field, Nevada

Creator:

Olson, Nansen H.

Abstract:

Magmatic-hydrothermal ore deposits are giant geochemical anomalies in the earth’s crust most often generated by normal magmatic terrestrial processes. They are often associated with oxidized and hydrous intermediate to highly evolved magmas that have concentrated metals and have the necessary components to efficiently extract and transport them as ascending magmatic-hydrothermal...

Stratification and mixing regimes in biological thin layers over the Mid-Atlantic Bight

Creator:

Shroyer, E. L., Benoit-Bird, Kelly J., Nash, J. D., and Moum, J. N.

Abstract:

We use density and microstructure data to characterize the properties and physical setting of optical thin layers observed over the New Jersey shelf in the summer of 2006. Layers were differentiated into two types by their vertical position in the water column, fluorescence intensity, and possibly community composition or cell...

Oregon climate assessment report : December 2010

Creator:

Dello, Kathie D., Mote, Philip W., and Oregon Climate Change Research Institute

Abstract:

The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....

Geochemical evidence in the northeast Lau Basin for subduction of the Cook-Austral volcanic chain in the Tonga Trench

Creator:

Price, Allison A., Jackson, Matthew G., Blichert-Toft, Janne, Blusztajn, Jerzy, Conatser, Christopher S., Konter, Jasper G., Koppers, Anthony A. P., and Kurz, Mark D.

Abstract:

Lau Basin basalts host an array of geochemical signatures that suggest incorporation of enriched mantle source material often associated with intraplate hotspots, but the origin of these signatures remain uncertain. Geochemical signatures associated with mantle material entrained from the nearby Samoan hotspot are present in northwest Lau Basin lavas, and...

An experimental investigation of the effects of temperature and dissolved oxygen on the growth of juvenile English sole and juvenile Dungeness crab

Creator:

Bancroft, Morgan P.

Abstract:

In the past two decades, occurrences of summertime upwelling-driven low dissolved oxygen (DO) events, or hypoxia, have increased along the northeast Pacific coast. If hypoxic events are severe enough to cause marine species mortality, the areas affected are often called "dead zones." In 2002 and again in 2006, the events...

The Geology and Geochemistry of the Haquira East Porphyry Copper Deposit of Southern Peru : Insights on the Timing, Temperature and Lifespan of the Magmatic-hydrothermal Alteration and Mineralization

Creator:

Cernuschi Rodilosso, Federico

Abstract:

This dissertation is informally divided into three major sections. In the first section (Chapter 2) I use data from field mapping, isotopic geochronology, whole rock geochemistry and trace element concentrations in zircons to examine the petrology, geochemistry and ages of the Haquira East porphyry copper deposit of southern Peru. In...

Of Mysid and Menidia: Sublethal Effects of Micro and Nanoplastics on Estuarine Indicator Species

Creator:

Dickens, John

Abstract:

Microplastics are widely distributed in aquatic environments. The term ‘microplastics’ encompasses a wide array of particles with unique polymer constituents, morphologies, and sources, such as automobile tire tread. Tire wear particles (TWP) can end up in waterways near densely populated municipalities, where they can interact with aquatic biota. Studying the...

Eastward Routing of Glacial Lake Agassiz Runoff caused the Younger Dryas Cold Event

Creator:

Leydet, David J.

Abstract:

The purpose of this thesis is to analyze an abrupt case of climate change in the past as a means to understand the mechanisms that force climate change. By looking to past analogs of climate change, we hopefully will gain an understanding of these events, which could be used to...
