Determination of unsaturation-, growth phase-, and growth rate-dependent hydrogen isotopic fractionation in C₃₇ alkenones produced by Emiliania huxleyi

Creator:: Wolhowe, Matthew D.
Abstract:: Recent works have investigated use of the hydrogen isotopic composition of C₃₇ alkenones (δD[subscript K37s]), lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. I discuss herein the factors impeding such an application and identify the potential alternative use of δD[subscript K37s] measurements as a proxy for non-thermal,...

Numerical model investigations of wind-driven coastal circulation

Creator:: Cervantes, Brandy T.
Abstract:: The effects of wind forcing on coastal ocean circulation are studied using a numerical modeling approach. The first region of interest is on the North Carolina shelf, where the Coastal Ocean Processes (CoOP) Inner Shelf Study (ISS) took place during August - November 1994. ISS observations are used to initialize,...

Model Studies of Near-Inertial Waves in Flow over the Oregon Continental Shelf

Creator:: Federiuk, J. and Allen, J. S.
Abstract:: Two-dimensional, primitive equation model studies of wind-forced flow over a continental shelf Show that, under upwelling conditions, high levels of near-inertial wave energy are found in the interior over the shelf. The regions of elevated wave energy, with maximum wave amplitudes of around ±0.2 m s⁻¹, persist for up to...

Long baroclinic planetary waves in a nonzonal vertically sheared mean flow

Creator:: Cerovecki, Ivana
Abstract:: We consider long planetary waves of annual period linearized about a steady, wind-driven subtropical (ST) gyre circulation. The circulation divides the gyre into an eastern zone (EZ) where only the surface layer is in steady motion and a western zone (WZ) where both the surface and the middle layer are...

Swash zone sediment suspension and transport

Creator:: Puleo, Jack A.
Abstract:: Swash zone processes are of significant importance to foreshore morphologic change. This thesis addresses the importance of the uprush and backwash fluid motions and flow duration effects to the resulting sediment transport. The analysis relates the field observations to well known sediment transport formulations as well as investigates the importance...

The Coastal Natural Hazards Policy Working Group: The Move to Update Oregon's Coastal Hazards Management

Creator:: Ansevin-Allen, Andrea C.
Abstract:: This paper will attempt to evaluate the prospects of the PWG's success based on their process so far, using models of policy development and implementation from Kingdon (1984), Putt and Springer (1989), and Sabatier and Mazmanian (1983). Because the PWG's work is not finished, the evaluation may help the group...

Coastal Wind-Driven Circulation in the Vicinity of a Bank. Part II: Modeling Flow over the Heceta Bank Complex on the Oregon Coast

Creator:: Whitney, Michael M. and Allen, J. S.
Abstract:: This study investigates wind-driven circulation in the vicinity of the Heceta Bank complex along the Oregon shelf. Numerical experiments forced with steady winds (0.1 Pa) are conducted; upwelling and downwelling cases are compared. The asymmetric bank bathymetry is the only configurational difference from the symmetric bank runs analyzed in Part...

Coastal Wind-Driven Circulation in the Vicinity of a Bank. Part I: Modeling Flow over Idealized Symmetric Banks

Creator:: Whitney, Michael M. and Allen, J. S.
Abstract:: This study examines how coastal banks influence wind-driven circulation along stratified continental shelves. Numerical experiments are conducted for idealized symmetric banks; the standard bank (200 km long and 50 km wide) has dimensions similar to the Heceta Bank complex along the Oregon shelf. Model runs are forced with 10 days...

Healthy Soil for Healthy Streams: City of Corvallis Stormwater Program

Creator:: Halsey, Jenna
Abstract:: In 2007, the City of Corvallis was issued a Phase II NPDES permit from the Oregon Department of Environmental Quality for non-point source pollution. In Corvallis, the majority of the stormwater conveyance system is separate from the sanitary sewer system. During a rain event, stormwater flows through pipes or over...

A modeling study of shelf circulation off northern California in the region of the Coastal Ocean Dynamics Experiment 2. Simulations and comparisons with observations

Creator:: Gan, Jianping and Allen, John S.
Abstract:: This is the second part of a modeling study of wind-forced flow on the continental shelf off northern California in the region (37°-40°N) of the Coastal Ocean Dynamics Experiment (CODE). Gan and Allen [2002] analyzed the shelf flow response to idealized wind stress forcing in a process-oriented study. The study...
