Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...

Shear and convective turbulence in a model of thermohaline intrusions

Creator:: Mueller, Rachael
Abstract:: Thermohaline interleaving is an important mechanism for laterally fluxing salt, heat, and nutrients between oceanic water masses. Interleaving is driven by a release of potential energy resulting from the vastly differing diffusivities of heat and salt in seawater. The flows are composed of stacked intrusions that flux more buoyant and...

Patterns of retention and vagrancy in larval Lost River and shortnose suckers from Upper Klamath Lake, Oregon

Creator:: Reithel, Susan A.
Abstract:: Larval transport and retention of two endangered suckers were studied in a highly altered lacustrine/riverine complex. The endangered populations of Lost River sucker, Deltistes luxatus, and shortnose sucker, Chasmistes brevirostris, in Upper Klamath Lake (UKL), Oregon are the largest remnant populations of these suckers. Downstream of UKL, the Keno Impoundment...

An empirical statistical model relating winds and ocean surface currents : implications for short-term current forecasts

Creator:: Zelenke, Brian Christopher
Abstract:: An empirical statistical model is developed that relates the non-tidal motion of the ocean surface currents off the Oregon coast to forecasts of the coastal winds. The empirical statistical model is then used to produce predictions of the surface currents that are evaluated for their agreement with measured currents. Measurements...

Marine habitat use of black-footed and Laysan albatrosses during the post-breeding season and their spatial and temporal overlap with commercial fisheries

Creator:: Fischer, Karen Naess
Abstract:: Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...

Primary production dynamics in the North Pacific subtropical gyre

Creator:: Corno, Guido
Abstract:: The North Pacific subtropical gyre (NPSG), once considered to be a biological desert due to low primary production (PP) and its associated variability, has been found more productive and variable than previously thought. The environmental conditions controlling this relatively high PP variability are yet to be elucidated, despite important implications...

10Be exposure ages of erratic boulders in southern Norway and implications for the history of the Fennoscandian Ice Sheet

Creator:: Goehring, Brent M.
Abstract:: This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age and...

Ecological subsidies to rocky shore communities : setting the stage for community dynamics in the Northeast Pacific

Creator:: Krenz, Christopher
Abstract:: This dissertation focuses on the importance of pelagic subsidies in the Northeast Pacific to rocky shore community regulation. My results document the patterns of pelagic subsidy supply, determine if those subsidies are correlated with community structure, and examine if community regulation differs between areas of high- and low-subsidies. Understanding how...

A comparison of depression, stress and self-image between younger and older adolescent mothers

Creator:: Kitzrow, Martha Anne.
Abstract:: Adolescent pregnancy is a major social problem which results in negative psychological, medical, developmental, economic and educational consequences for both mother and child. A review of the literature examined psychological and sociocultural factors and negative consequences associated with adolescent pregnancy. There has been little research on age specific differences between...
