Wildlife habitat mapping has evolved at a rapid pace over the last few decades. Beginning with simple, often subjective,
hand-drawn maps, habitat mapping now involves complex species distribution models (SDMs) using
mapped predictor variables...

Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine
Science Center (HMSC) campus in Newport, Oregon became necessary to halt erosion that
threatened both HMSC critical infrastructure (seawater storage...

The three-dimensional (3D) double-ridge internal tide interference in the Luzon Strait in the South China
Sea is examined by comparing 3D and two-dimensional (2D) realistic simulations. Both the 3D simulations
and observations indicate the...

The overall objective of this study is to address questions concerning the long-term
mechanical strength of the lithosphere across the equatorial margin of Brazil. The
approach used in this study consists of calculating the frequency response...

Physical-biological interactions in the Southern Ocean were investigated using
remote sensing data from several different satellite sensors. Satellite sea surface
temperature data were used to study the dynamics of the Antarctic Polar Front (PF)....

We modeled surface wetness at high resolution, using a dynamic hydrology model, to predict flood and
swamp water mosquito abundances. Historical meteorologic data, as well as topographic, soil, and vegetation
data, were used to model surface...

Seismic data and seafloor samples indicate the presence of free gas, gas hydrate, and
fluid seeps south of the Gorda Escarpment, a topographic feature that marks the eastern
end of the Gorda/Pacific transform plate boundary southwest of Cape...

Cold air drainage and pooling occur in many mountain valleys, especially at night and during winter. Local
climate regimes associated with frequent cold air pooling have substantial impacts on species phenology, distribution and
diversity....

The thesis area includes 54 square miles of the southeastern
Cuddy Mountains in west-central Idaho. The oldest rocks within the
area are plutonic phases of the Jurassic Cuddy Mountain complex.
These and Cretaceous (?) intrusive and associated (?)...

A study was undertaken in the Willamette Valley, Oregon, to document
1971 land use patterns as well as land use change in a smaller study
area in the 16 years prior, and to relate these to soil characteristics.
Quantification of these...

The Nanga Parbat-Haramosh massif (NPHM) is a north-south trending
structural and topographic high, which interrupts the east-west trend
of the Himalaya in northern Pakistan. Previously, the massif was
thought to be bounded by the Main Mantle...

Multivariate morphometric analyses performed on ten populations
of Aneides ferreus indicate that phenotypic expression in this species
is exceedingly similar, but that on a fine scale there is considerable
significant heterogeneity between most...
