Geomicrobiology of marine sediment containing methane

Creator:

Briggs, Brandon R.

Abstract:

Marine sediments contain an abundance of methane that is biologically produced and plays a significant role in the global carbon cycle. Microbes responsible for the carbon cycle in marine sediments, and the processes that they carry out, need to be characterized in order to fully understand the role of this...

Construction of a model organism for performing calcium carbonate precipitation in a porous media reactor

Creator:

Kaufman, Megan J.

Abstract:

Aquifers are an important storage location and source of fresh groundwater. They may become polluted by a number of contaminants including mobile divalent radionuclides such as strontium-90 which is a byproduct of uranium fission. A method for remediating such divalent radionuclides is sequestration through co-precipitation into calcium carbonate. Calcium carbonate...

Microbiology of basalts targeted for deep geological carbon sequestration : field observations and laboratory experiments

Creator:

Lavalleur, Heather J.

Abstract:

With rising concentrations of CO₂ in the Earth's atmosphere causing concern about climate change, many solutions are being presented to decrease emissions. One of the proposed solutions is to sequester excess CO₂ in geological formations such as basalt. The deep subsurface is known to harbor much of the microbial biomass...

Bioinformatics applied to freshwater cyanobacterial blooms and cyanophage

Creator:

Schwartz, Andrew D.

Abstract:

Freshwater cyanobacterial blooms are a nuisance and health threat in the Pacific Northwest. The accepted methods of characterizing these blooms by microscopic cell counts cannot differentiate between toxic and non-toxic strains of the cyanobacterium Microcystis. Also, there is limited understanding of freshwater cyanophage that may control bloom dynamics. In order...

Biotic alteration of oceanic basalt glass

Creator:

Drinnan, Megan R.

Abstract:

The subsurface microbial biosphere in the igneous oceanic crust has implications for global geochemical cycling, early life on Earth, and the search for life on Mars. Microscopic evidence of a subsurface microbial ecosystem includes biotic alteration textures associated with basaltic glass. The exact conditions in the basaltic layer that make...

Influence of a Sedimentary Source of Nd on Deep Ocean εNd Distributions

Creator:

Abbott, April N.

Abstract:

Ocean circulation is an important component in Earth's climate system. Predicting future climate and circulation changes requires an improved understanding of the past relationship between climate and ocean currents. The neodymium isotope composition (εNd) of water masses is frequently used as a quasi-conservative tracer to reconstruct ocean circulation. The current...

Examining parameters of vectorial capacity for mosquitoes associated with stormwater catch basins in Corvallis, Oregon

Creator:

Townzen, Jill S.

Abstract:

This research examines two of parameters of vectorial capacity for mosquitoes associated with catch basins in Corvallis, Oregon. The parameters of interest were determining 1) abundance of the mosquito species associated with the catch basins and 2) feeding patterns of local mosquito species. Three species of mosquitoes were collected from...

Automated web-based analysis and visualization of spatiotemporal data

Creator:

Keon, Dylan B.

Abstract:

Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...

Microbial diversity, metabolic potential, and transcriptional activity along the inner continental shelf of the Northeast Pacific Ocean

Creator:

Bertagnolli, Anthony D.

Abstract:

Continental shelves located along eastern boundary currents occupy relatively small volumes of the world’s oceans, yet are responsible for a large proportion of global primary production. The Oregon coast is among these ecosystems. Recent analyses of dissolved oxygen at shallow depths in the water column has suggested increasing episodes of...

Heat fluxes in the hyporheic zone of a gravel bar on the Willamette River, Oregon

Creator:

Squeochs, Graysen M.

Abstract:

Increased water temperatures and thermal loading due to anthropogenic inputs has been shown to negatively impact the lifecycles of aquatic organisms in riverine systems (Poole and Berman 2001; Hannah, Malcolm et al. 2004; Quinn, Gagne et al. 2004). The studies enclosed in this thesis evaluate and quantify the heat fluxes...
