During the 27-month period of this project (July 1, 2005-September 30, 2007), the Northwest Digital Archives achieved significant growth in membership, in its finding aid database, and in usage of the database by researchers; conducted extensive testing of the finding aids database with a variety of researcher communities; continued dialogue...
Distributed deformation in the backarc of Cascadia is complex. Off the west
coast lies the Cascadia convergent margin. East of the plate boundary,
clockwise rotation of the Oregon Coast Range block with respect to stable
North America influences backarc deformation, causing extensional faults in
southeast Oregon, contraction folding in southeast...

This paper presents a seismic sequence and structural analysis of a high-resolution three-dimensional seismic reflection survey that was acquired in June 2000 in preparation for Ocean Drilling Program (ODP) Leg 204. The seismic data were correlated with coring and logging results from nine sites drilled in 2002 during Leg 204....
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
Hydrate Ridge is an accretionary thrust ridge located on the lower slope of the central Cascadia convergent margin. Structural mapping based on two-dimensional and three-dimensional multichannel seismic reflection profiles and gridded bathymetry coupled with deep-towed sidescan sonar data and Ocean Drilling Program (ODP) biostratigraphy suggests that seafloor fluid venting patterns...
