A change to a warmer, drier climate beginning as early as 1900 was responsible
for triggering a dramatic, rapid retreat of Collier Glacier, Oregon, between 1924 and
1940. Although there was a dramatic decrease in precipitation contemporaneous with this observed "step-function" response of mass loss, it is unclear if climate...

In 1978, a ten year project was begun to examine
the synecological effects of livestock grazing riparian
ecosystems. A multitude of biotic arid physical factors,
many which were unique to riparian ecosystems, interacted
to form a complex and diverse riparian ecosystem.
A total of 256 stands of vegetation representing 60...
Paleozoic limestones, dolomites, quartz arenites, and other
clastic rocks were mapped in the vicinity of Dobbin Summit and
Clear Creek in the central Monitor Range. Sedimentary rock units
present in this area represent the shallow-shelf eastern assemblage
and basin and also the basin-slope facies of the traditional limestoneclastic
assemblage.
The...
Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...
Neogene rocks of the Deschutes basin include the middle Miocene
Columbia River Basalt Group and Simtustus Formation, and late Miocene
to early Pliocene Deschutes Formation. Assignment of Prineville
chemical-type flows to the Grande Ronde Basalt of the Columbia River
Basalt Group is based upon correlation of these lavas from their...
Sequence stratigraphic analysis of the southern Tyee basin, Oregon Coast Range, reveals
that the lower to middle Eocene forearc and subduction zone strata comprise four depositional
sequences. Sequence I (lower Umpqua Group) represents a partially subducted accretionary
wedge. Sequence II (upper Umpqua Group) is a deltaic sequence that filled irregular...
Surface and subsurface data indicate that Cretaceous strata
in the southern Ventura basin are part of the northward prograding
Chatsworth submarine fan. The fan extends westward as far as
Trancas Beach in the Santa Monica Mountains and wells in the
Oxnard Plain and on Oak Ridge. The eastern edge of...
Roberta Hall was part of an OSU [Oregon State University team that made exchange visits with women scholars in Nepal from 1995 through 1997. She spent Jan.-March of 1997 in Nepal and brought back extensive notes from observations and interviews; a bibliography on prehistory, current environmental problems, and women’s concerns;...
Subsurface mapping was used to determine the structure andgeologic history of the South Cuyama dome and part of the Russellfault in the South Cuyama oil field area.

In 1970 a phytosociological reconnaissance consisting of 135 plots in the Subalpine Meadow Zone was made. These samples were sorted using an association table and several Alpine Zone and very early seral communities were set aside, An additional hundred plots taken by M. J. Hamann were
incorporated with these and...
Analytical methods capable of trace measurement of semi-volatile organic
compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a
result of long-range and regional atmospheric transport and deposition. The following
study compares the results of two analytical methods, one using pressurized liquid
extraction (PLE) and the...
Program description: Do users want simpler access to "best sources" for subject research? Should libraries filter information by discipline, subject area or course? Should information be tailored to undergraduate level? This presentation will present findings from research on these and other questions.
Support Vector Machines (SVM) and Random Forests (RF) have
consistently outperformed other machine learning algorithms on a variety of
problems. SVM can be used for classification and regression on many types of
data (e.g. nonlinear, high dimensional), but cannot handle missing or mixed data.
This research implements a permutation-based variable...
