During the summer of 1972 we sampled the Umpqua River estuary to determine distribution of fish populations. As a part of that study temperature and salinity data were collected monthly throughout the estuary. The environmental data should help explain the distributions of various fishes within the estuary and be useful...
"This information report provides an updated summary of all coastal shad tagging studies conducted by the Fish Commission. I believe these studies represent the only shad tagged in Oregon coastal streams south of the Columbia River. No new field work is reported. My intent is to tabulate, consolidate, update, and...
"Striped bass (Morone saxatilis) were tagged on the Umpqua and Smith rivers (Figure 1) to estimate the numbers of bass recruited to the commercial fishery and to gather information on migration habits of bass in these rivers. Small numbers of striped bass were tagged in the summers of 1971 and...
The pregnancy and postpartum periods are full of major life transitions. So often, the focus of the literature is about the unborn baby and physical changes a woman experiences throughout this timeframe. Many sources often overlook women’s personal experiences in the perinatal period. Despite an increase in perinatal mood and...
The Greenhorn Mountains contain a tectonic ally disrupted
ophiolite and both arc-derived and pelagic sediments. Age of major
sedimentary units within and bordering the thesis area is Early
Permian, based upon dates of conodonts and fusulinids from contemporaneous
but allocthanous limestones. Sediments near the south
boundary of the thesis area...

AN ABSTRACT OF THE THESIS OF
Ellen Domaratius Mullen for the
A high-temperature, high-pressure autoclave has been
adapted for use with a high-field nuclear magnetic
resonance spectrometer. The autoclave has an internal
pressure range of atmospheric pressure to 1.5 kbar and a
temperature range of 273 K to 1900 K. The autoclave is
usable in a high field (8 T) magnet...
Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
