In summer 1988, we made repeated mesoscale surveys of a grid extending 200 km offshore between
37°N and 39°N in the coastal transition zone off northern California, obtaining continuous acoustic
Doppler current profiler data and conductivity-temperature-depth data at standard stations 25 km apart
on alongshore sections 40 km apart. All...
The calibration factor of LaCoste-Romberg , surface-ship gravity
meter 5-9 was checked against a 1200 mgal range of land base stations
along the West Coast of the United States. Previous checks at other
base stations provided conflicting results as to the accuracy of this
meter's calibration factor supplied by the...
Air–sea coupling during coastal upwelling was examined through idealized three-dimensional numerical simulations with a coupled atmosphere–ocean mesoscale model. Geometry, topography, and initial and
boundary conditions were chosen to be representative of summertime coastal conditions off the Oregon coast. Over the 72-h simulations, sea surface temperatures were reduced several degrees near...
This repository item contains the files needed to reproduce the results reported in the published work entitled "Runups of unusual size: rogueness and variability of swash" in the Journal of Geophysical Research. As described in the publication, the results described within it pertain to simulations of wave runup for various...
Measurements of currents and turbulence beneath a geostationary ship in the equatorial Indian Ocean during a period of weak surface forcing revealed unexpectedly strong turbulence beneath the surface mixed layer. Coincident with the turbulence was a marked reduction of the current speeds registered by shipboard Doppler current profilers, and an...
The Columbia River Basalt consists of dozens of seemingly identical flows of basalt covering thousands of square miles of Oregon, Washington, and Idaho. For years, detailed mapping of the units relied almost entirely on subtle petrographic distinctions, the presence or absence of interbeds, and actual walking along contacts in the...
Remote-access computer file serials, often referred to simply as electronic serials, possess characteristics that challenge our definition of the term “serial” and our ability to catalog them according to the established cataloging code. These challenges are reflected in the library science literature, where cataloging and indexing issues have generated thoughtful...
Our studies and those of our colleagues in Idaho indicate that the western Snake River Basin is a major geothermal province, similar in some ways to the Imperial Valley Geothermal Province. Deep drilling should encounter high temperature fluids in permeable rocks below 2 km and at shallower depths where permeability...
The U.S. Forest Service has published the final version of regulations on the surface use of National Forest lands under the amended mining laws of 1872. These regulations became effective September 1, 1974. Although the Mining Law of 1872 is still largely intact, the new regulations place some requirements in...
A marine geophysical study using shallow seismic reflection, gravity and magnetic methods of investigation was done for an offshore area near Newport, Oregon. The area is bounded by the latitudes 44°1O' to 44°50' N. and longitudes 124°07' to 124°30' W. The interpretation of observational data showed that the geology of...
The longshore variability of the coastal response to hurricanes may be examined within the framework of a storm-impact scaling model that compares spatially-variable beach morphology and fluid forcing. The relative elevations of dune height and storm-induced water levels are used to define three impact regimes (swash, collision, and overwash), within...
The plate tectonic history of Oregon is but one piece of a worldwide jigsaw puzzle encompassing much of geologic time. With the splitting of Pangaea in Mesozoic times, Oregon has occupied the leading edge of the North American Plate as it has impinged upon the ancestral oceanic East Pacific Plate....
One of the most beautiful and geologically interesting parts of the Oregon coast is in the vicinity of Cape Arago near Charleston, 10 miles west of Coos Bay. Three very fine state parks have been developed here. They are (from north to south): Sunset Bay, Shore Acres, and Cape Arago...
Periodic violent eruptions from many different centers during Cenozoic time deposited vast quantities of pyroclastic material as ash-flow tuffs over most of Oregon, although the Coast Ranges and isolated patches elsewhere in the state appear to have been spared these recurring inundations. Eruptions occurred at different times throughout the Cenozoic,...
The United States has enormous deposits of oil shale which, if developed, could provide energy resources for centuries. Because of the vast size of these deposits, they are currently receiving a great deal of attention. This issue of The ORE BIN is devoted to a discussion of oil shale --...
The purpose of this study of the Lyons flora is to determine the age and paleoecology of the flora through the examination and identification of the fossil plant species of the flora. The plant fossils comprising the Lyons flora were collected from a locality in the upper Thomas Creek area,...
The Oregon coast between Yaquina Head and Government Point owes its scenic grandeur to a unique wedding of ancient and recent marine environments. Visitors to Beverly Beach State Park, located in the southern part of this coastal strip, have a rare opportunity to wander along a shoreline that some 15...

Stein's Pillar area, central Oregon / Aaron C. Waters -- Seismic reflection studies of buried channels off the Columbia River / Joseph W. Berg, Jr., John M. King, and Paul R. Carlson.
Everyone involved with the mining and petroleum industries, either directly or indirectly, is aware of the mounting concern by the general public with the possibly deleterious effects of mineral exploration and development on the environment. Oftentimes the outcry about "desecration of the land" is not based on actual knowledge of...
The stacks off the southern Oregon coast have been studied very little because of difficulties of access (see, for example, Weissenborn and Snavely, 1968). Work described herein was helicopter-supported; skillful piloting by Earl Lady permitted landings on or close approaches to many stacks. To help delineate the structure, field work...
Adult onset progressive alopecia and leukotrichia developed in 2 registered black Angus cows, aged 6 and 7
years. Histopathologic findings in skin were prominent melanin clumping and degeneration of matrix cells with formation
of giant multinucleate cells within hair bulbs, accompanied by peribulbar melanin incontinence and fibrosis and dystrophic
hair...
Over a 3.5-year period, 4 Rocky Mountain goats (Oreamnos americanus), housed at a single facility, developed clinical disease attributed to infection by Caprine arthritis encephalitis virus (CAEV). Ages ranged from 1 to 10 years. Three of the goats, a 1-year-old female, a 2-year-old male, and a 5-year-old male, had been...
Hmong women in the U.S. have low rates of breast and cervical cancer screening, and the factors that influence screening in this population are not well-understood. This qualitative study explored family and clan influences on Hmong women’s breast and cervical cancer screening attitudes and behavior. We conducted in-depth interviews with...
There is increasing evidence that aging is affected by biological (circadian) clocks – the internal mechanisms that coordinate daily changes in gene expression, physiological functions and behavior with external day/night cycles. Recent data suggest that disruption of the mammalian circadian clock results in accelerated aging and increased age‐related pathologies such...
Sudden changes occur where the mean values associated with two adjacent non-overlapping
windows of data are anomalously different, and the transition between the
window means occurs over a scale that is small relative to the scale of the windows.
Positions of sudden changes can be economically retrieved. The sudden change...
Background: Considering the pharmacokinetic and pharmacodynamic aspects of different medications, it is plausible that the age of a smoker could affect the half-life of these drugs. The aim of this study was to compare the effectiveness of smoking cessation drugs (nicotine replacement therapy, bupropion, and varenicline) used either in isolation...
Digital repository managers rely on usage metrics such as the number of downloads to demonstrate research visibility and impacts of the repositories. Increasingly, they find that current tools such as spreadsheets and charts are ineffective for revealing important elements of usage, including reader locations, and for attracting the targeted audiences....
Csanady (1998) presents solutions for time-dependent wind-driven flow in a barotropic
coastal ocean. We disagree with two of his three boundary condition options and wish to
clarify the origin of the non-wavelike aspect of the flow
Three general types of swimbladders were found in the eight species of myctophids studied: gas-filled, fat-invested, and atrophied or reduced. Small specimens of all species had thin-walled, gas-filled swimbladders. Large specimens of Stenobrachius leucopsarus had fat-invested swim-bladders and large Diaphus theta had either gas-filled or atrophied swimbladders, as found by...

A coupled climate-carbon cycle model and ice core CO2 data from the last glacial
period are used to explore the impact of changes in ocean circulation on atmospheric
CO2 concentrations on millennial time scales. In the model, stronger wind
driven circulation increases atmospheric CO2. Changes in the buoyancy driven
deep...
As the Galápagos hot spot is approached from the west along the Galápagos Spreading Center there are systematic increases in crustal thickness and in the K/Ti, Nb/Zr, ³He/⁴He, H₂O, and Na₂O content of lavas recovered from the spreading axis. These increases correlate with progressive transitions from rift valley to axial...
