Sediments of the central Chile margin record changes in ocean circulation and
continental erosion associated with large–scale climate change. Here Antarctic–
influenced Southern Ocean currents flow equatorward, forming a link between the high–
and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important
conduit that ventilates South...
Large barite (BaSO4) structures mark cold seeps in the southern San Clemente Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes measured in surrounding California Borderland basins. Analyses of sediment trap material, water column samples, sediments and pore water indicate that expected bariumbearing mineral...
This study is composed of two parts. Section I deals with
developed moorages and marinas--where they are; what services are
offered in each, and how well the existing supply of permanent moorages
serves the boating public. Section II examines the need for temporary
'harbors of refuge' in the area, what...
Tillamook Bay is the second largest estuary on the Oregon coast, and concerns have been raised whether human induced impacts have been responsible for the perceived increase in sedimentation rates during the past century. Major land-use practices within the five watersheds of the Bay include logging, forest fires, the construction...
A study was conducted to determine the heat transfer characteristics
of pin finned heat sinks in natural convection. Three pin
diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins
were attached to the base in two arrangements, triangular and
rectangular, forming a horizontal array. Pin spacing was...
More Americans are participating in sport every year
and several organizations have made it their mission to
provide the opportunity for organized sport participation.
College and University intramural departments are one of
those organizations. They provide participation
opportunities on nearly every college campus. The review of
literature identifies the sociological...
In the summer of 2001 the Oregon Coast Aquarium opened a new exhibit on sharks entitled, "Great White Mystery: What Happened to Surfer Bob?" For the purposes of this study, a survey was designed to determine whether visitors to the new exhibit learned factual information or left with changed attitudes...
The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...
Five simulated precipitation patterns characteristic of the Columbia
Basin and Plateau region and six fertilization rates were evaluated
for their effect on percent crude protein, percent in vitro dry matter
digestibility, fiber content, and yield of wheat aftermath on a commercial
farm in north central Oregon.
The higher moisture regimes...
