6,300 acres of project lands. Drainage facilities will also be built.
Flood control and fish and wildlife values will be improved. The
proj ect includes 6,300 acres of new land and 12,650 acres of presently
irrigated land needing a supplemental...

Climate change is arguably the greatest challenge to conservation of our time. Most
vulnerability assessments rely on past and current species distributions to predict
future persistence but ignore species’ abilities to disperse through...

Coastal foredunes protect lives, infrastructure, and ecosystems during severe storms. A range of
approaches, ranging from simple (e.g., geometric) to complex (e.g., process-based) predictive
models, have been developed to quantify overtopping and...

Eddy detection and tracking algorithms are applied to both satellite altimetry and a
high‐resolution (dx = 5 km) climatological model solution of the U.S. West Coast to study
the properties of surface and undercurrent eddies in the California...

Using a linear quasi-geostrophic model of large scale spiraling flow and vertical density
gradient in the eastern North Pacific, we evaluate the complex dispersion relationships
for quasi-geostrophic waves. Our calculations indicate that the...

The High Lava Plains province (HLP) is a late Cenozoic bimodal volcanic field at
the northern margin of the Basin and Range province in southeastern Oregon that hosts
a westward younging trend of silicic volcanism that crudely mirrors...

Satellite-derived data provide the temporal means and seasonal and nonseasonal
variability of four physical and biological parameters off Oregon and Washington
(41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll...

The historical function of fire in sagebrush steppe has been altered by 19th century
overgrazing, active fire suppression, annual grass invasion and encroachment of woody
species. The significance of fire to these systems is known, but research...
