Shoreward propagating, mode 2 nonlinear waves appear sporadically in mooring records obtained off the coast of New Jersey in the summer of 2006. Individual mode 2 packets were tracked between two moorings separated by 1 km; however, packets could not be tracked between moorings separated by greater distances from one...
Present GEK (Geomagnetic Electrokinetograph) theory is extended
to include internal waves of the lowest mode. The predicted
towed electrode GEK signal is determined to second-order for long-crested
internal waves in a finite but deep ocean. The analysis includes
the determination of GEK signatures for small amplitude and
finite amplitude interfacial...
The general expressions for finding the network functions, e.g.,
the immittance and the scattering parameters, of a general, uniformly
coupled n-line structure in an inhomogeneous medium are derived in
terms of the normal mode parameters of the system. These are used to
compute or to derive the explicit expressions for...
Multiport network functions, such as impedance matrix
parameters and scattering parameters, of general multiple
coupled slab waveguides are derived in terms of the normal
mode parameters of the system. These characteristic normal
mode parameters include the propagation constants, the
modal impedances, and the eigenvector matrices. It is
shown that the...
OWET commissioned this gap analysis to assess the infrastructure needs of ocean renewable energy and compare those needs against the existing and planned infrastructure capabilities in Oregon. The Wave Energy Infrastructure Assessment in Oregon report summarizes the results of the assessment performed by Advanced Research
Corporation and is intended to...
This project was carried out collaboratively by Oregon State University (OSU) and the Oregon Department of Geology and Mineral Industries (DOGAMI) and involved continuation of the beach monitoring program begun in summer 2009 to determine baseline conditions and beach variability at the site of the planned Reedsport wave energy conversion...
The potential for creating underwater noise disturbance is one environmental impact that must be accounted for by wave energy developers to meet the needs of regulatory agencies. This review study has been conducted to provide a concise knowledge base of the expected underwater noise conditions in the near shore environment...
Theoretical breaking criteria for progressive surface gravity
waves are examined, and laboratory and field experiments concerned
with breaking waves are reviewed with respect to the testing of these
breaking criteria. The measurements of Komar and Simmons are
presented here for the first time. Only three theoretical breaking
criteria have been...
Geo-Marine, Inc. (GMI) conducted an offshore avian radar baseline study for Oregon Wave Energy Trust (OWET) for a wave energy study located northwest of Reedsport, Oregon from 25 August through 29 October 2010. The study was conducted from shore with GMI’s Mobile Avian Radar System (MARS®). The MARS® was equipped...
This report establishes an industry knowledge base for existing anchoring and mooring techniques as applied to wave energy conversion (WEC) devices in and around Oregon. This report on anchoring and mooring techniques is derived from the cumulative experiences of engineers and scientists with many years of experience analyzing, designing and...
