Floods are the most frequent natural disaster, causing more loss of life and property than any other in the USA. Floods also
strongly influence the structure and function of watersheds, stream channels, and aquatic ecosystems. The Pacific...

University deployed two arrays of three sonobuoys over the Blanco
fracture zone and two arrays of four sonobuoys over the Gorda ridge
to detect and locate microearthquakes. Microearthquake activity predicted
by plate tectonic theory for the Blanco...

A proposed modeling technique that yields a best fit to observed
wide-angle reflection profiles incorporates (1) the use of migrated vertical
reflection profiles to provide topographic control, (2) ray tracing
to produce theoretical wide-angle...

Broadband body waves recorded at 15 digital
seismic stations worldwide are used to study the rupture
process of the May 23, 1989 Macquarie Ridge earthquake.
The centroidal solution (strike 211°, dip 86°, rake 180°, and
depth of 10 km below the...

Submersible investigations of the Cascadia accretionary
complex have identified localized venting of methane gas
bubbles in association with gas hydrate occurrence. Acoustic
profiles of these bubble plumes in the water column in the
vicinity of...

Observations of internal solitary waves (ISWs) and of their role in sediment
resuspension during the Coastal Mixing and Optics 1996 (CMO 96) experiment are
reported. The largest resuspension events observed in the experiment can be related to...

Using remotely-sensed metrics to identify regions containing high animal diversity and/or specific animal species
or guilds can help prioritize forest management and conservation objectives across actively managed landscapes.
We predicted avian...

The morphology and genesis of soils of the Willamette series
and of some Willamette-associated soils and their relationships to
geomorphic surfaces were studied in an area near McCoy, Polk
County, Oregon. Influences of regional extent, such as...

Side-scan sonar records in Oregon's Coos Bay estuary navigation
channels were obtained at intervals of two to three months during the
November 1974 - October 1975 time period from Coos Bay Channel Mile
11+50 to 15+20, and from a reach in the...

In order to develop three models for use in quantifying the
environmental conditions of reforestation, extensive measurements
required for energy balance calculations were taken for a
reforestation site in southwest Oregon. The models are used to...
