This document provides definitions and a general overview of streams and lakes of San Juan County (SJC) and then describes impacts to these water bodies and strategies for determining widths of buffers that protect their functions. It similarly provides definitions and a general overview of SJC upland (terrestrial) habitats, describes...
Our oceans surround us, and we depend upon them for food, transportation, and recreation. They affect us daily as they shape our climate and rattle our world with unexpected events. Current headlines indicate that they are in flux and perhaps in trouble. Coral reefs are dying due to rising ocean...
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...
Geophysical data collected in 1975 and 1976 reveal major
crustal and tectonic elements of the continental margin of southern
Baja California. Gravity, magnetic, seismic reflection and bathymetric data show seaward extension of the islands enclosing Magdalena
and Almejas Bays. A seismic reflection profile, oriented
approximately normal to the trend of...
Two studies were conducted involving rare earth elements. In the
first study, the use of rare earth diethylenetriaminepentaacetic acid
(DTPA) complexes as stable actiable tracers, a method of stable-isotope
tracing with post-sampling neutron activation analysis, was explored.
The persistence of rare earth DTPA complexes in estuarine waters was
measured in...
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...
What affects the oceans affects terra firma. Ocean Solutions, Earth Solutions gathers the insights of more than 50 ocean and coastal science researchers exploring ocean components and their relationships, patterns, and trends over time and space. The book's 16 chapters feature geographic information system (GIS) best practices and include additional...
In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...
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...
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...
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
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...
As editors of the Marine Science and Technology section for the last three editions of Magazines for Libraries (MFL), we developed lists of journals and annotations to help guide marine sciences acquisitions for all types of libraries. We recommended essential titles at the same time we needed to cancel some...
Many Earth science disciplines are currently experiencing the emergence of new ways of data
publication and the establishment of an information technology infrastructure for data archiving and
exchange. Building on efforts to standardize data and metadata publication in geochemistry [Staudigel et
al., 2002], here we discuss options for data publication,...
As GIS becomes more prominent in academic classrooms at all levels of education, the subject of geography and its related disciplines can be approached with a geospatial technology perspective, using new tools and lesson plans. The implementation of Google Earth in classrooms is just one example of this. Research was...
The Oregon State University (OSU) President s Commission on Ocean, Coastal and Earth System Futures was charged by President Edward Ray to explore and identify a far-reaching vision for the future
of OSU as a Land Grant and Sea Grant institution - one that integrates the biological, physical, and social...
In the process of building international water policies and management institutions, like international treaties and River Basin Organizations, States simultaneously signal the values that they view as most important in these different institutions. Examining expressed and acted-upon values for transboundary freshwater management are currently under-explored areas where overlapping lenses of...
Seismic refraction, reflection and gravity data obtained
across the Peru continental margin and Nazca Plate
at 9° S. permit a detailed determination of crustal structure.
Complex structures normal to the profile require the
development of a ray trace technique to analyze first and
later arrivals for eleven overlapping refraction lines....
We report on geochemical data from anoxic sequences of the Nicobar Fan, recovered during International Ocean Discovery Program (IODP) expedition 362 to the Sumatra subduction zone. Analyses include strontium and carbon isotope composition of pore fluids, elemental and isotopic composition of carbonate concretions, and whole sediment analyses.
Because barriers are low-lying and dynamic landforms, they are especially sensitive to changing environmental conditions. The continued existence of barriers will depend on the degree to which these landforms can maintain elevation above sea level while also migrating landward. We are increasingly learning that ecomorphodynamic interactions (i.e., interactions between morphology,...
A broad definition of forestry would include the study of trees and forests and their use by people. Modern, "science-based" forestry began in the nineteenth century when Europeans looked for specialists who could address questions on wood supply and extraction both at home and in their colonies. The threat of...
The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...
A broad definition of forestry would include the study of trees, forests, and the habitat they provide as well as their use by people. Modern “science-based” forestry began in the nineteenth century, when Europeans looked for specialists who could address questions on wood supply and extraction both at home and...
GIScience (geographic information science) is a scholarly discipline that addresses
fundamental issues surrounding the use of a variety of digital technologies to handle
geographic information; namely, information about places, activities, and phenomena on
and near the surface of the Earth that are stored in maps or images. GIScience includes
the...
Oregon Wildlife is published monthly by the Oregon State Department of Fish and Wildlife. Volumes 1 through 28 were entitled Oregon Game Commission Bulletin.
