Stratigraphic correlation of seismoturbidites and the integration of sediment cores with 3.5 kHz chirp subbottom data in southern Cascadia

Creator:: Black, Bran
Abstract:: In order to evaluate the shallow stratigraphy along the southern Cascadia abyssal margin and northern California abyssal plain, CHIRP subbottom profiles capable of imaging individual turbidite beds in the upper tens of meters of the subsurface were collected. Reflectors imaged with the 3.5 kHz CHIRP subbottom data represent turbidite beds...

Sixth Oregon climate assessment

Creator:: Fleishman, Erica and Oregon Climate Change Research Institute
Abstract:: Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This sixth Oregon...

The provenance and trace element signatures of MORB anorthitic plagioclase

Creator:: Burleigh, Andrew W.
Abstract:: In an attempt to understand the phase equilibria and petrogenesis of MORB anorthitic plagioclase, Cr-spinel commonly hosted within anorthitic plagioclase has been investigated petrographically and compositionally. Based on spinel-anorthite relationships from three samples of plagioclase ultra-phyric basalt (PUB; Southeast Indian Ridge, Axial Seamount and West Valley Segment, Juan de Fuca...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:: Lange, Amy E.
Abstract:: Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...

Growth, Condition, and Survival of Larval Arctic Cod and Walleye Pollock in a Warming Ocean

Creator:: Koenker, Brittany L.
Abstract:: Arctic cod (Boreogadus saida) is an ecologically significant species that plays a critical role channeling energy throughout the Arctic marine food web. Arctic cod is uniquely adapted to occupy ice edge habitats, however, a basic understanding of its larval physiology and habitat requirements is lacking due to widespread sea ice...

Quantitative Metatranscriptomics and Biogeochemical Rate Measurements Reveal Microbial Pathways Driving Carbon and Nitrogen Cycles in an Arctic Lagoon

Creator:: Griffin, Natasha A.
Abstract:: Microbial communities in Arctic coastal lagoons drive biogeochemical cycles at the terrestrial-marine interface and help to determine the fate and form of resources like nitrogen (N) and carbon (C) as they are delivered to the Arctic Ocean. Though rising rates of primary production in the Arctic Ocean are well-characterized, the...

Larval Biogeography and Varying Spawning Behavior of Bering Sea Groundfishes: Implications for Management in a Changing Seascape

Creator:: Vary, Laura
Abstract:: Early life stages of marine fishes exert substantial control on the productivity and resilience of marine fisheries, as these life stages represent periods of extreme mortality. Additionally, eggs and larvae of marine fishes respond rapidly to environmental change and can thus be used to infer ecosystem-wide responses to climate change...

Magnetotelluric Constraints on Lithospheric Properties in the Southeastern United States

Creator:: Murphy, Benjamin S.
Abstract:: By inverting EarthScope long-period magnetotelluric (MT) data from the southeastern United States (SEUS), we obtain electrical conductivity images that provides key insights into the geodynamics of this region. Significantly, we resolve a highly electrically resistive block that extends to mantle depths beneath the modern Piedmont and Coastal Plain physiographic provinces....

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:: Seabrook, Sarah
Abstract:: Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...
