In September of 1989, the site of an active seafloor methane vent was confirmed
approximately 20 km off the coast of Oregon in shelf waters 135 m deep. The location of
the vent had been described to Oregon State University oceanographers by a local
commercial fisherman. Preliminary observations in 1989...
A structure map was constructed of the continental shelf between
Cape Blanco and Coos Bay, Oregon, exclusively from an interpretation
of approximately 700 km of continuous seismic profiles.
At least ten discernible seismic units were mapped on the bases of
acoustic appearance, lateral continuity, angular unconformities, and
faults. The offshore...
Candidatus Pelagibacter ubique is the first cultured representative of the SAR11 clade, a clade that is found throughout the oceans and accounts for approximately 25% of all bacterial cells [1]. It has a streamlined genome that is the smallest of any known free-living organism. In this study the complete genome...
Sediments on the inner portion of the Oregon continental shelf
consist of clean, well-sorted, detrital sand. This sand has an average
median diameter of 2.53Φ (. 173 mm) and is both positively and
negatively skewed. Deposits with median diameters in the coarse
sand and gravel classes occur at depths of...
From measurements of thermal and electrical conductivities of
64 ocean sediment samples obtained from piston cores taken off the
Oregon Coast, and from 37 water-saturated sandstone samples analyzed
by Zierfuss and Van der Vliet (1956), as well as 51 thermal
conductivities and water contents of ocean sediments analyzed by
Ratcliffe...

Continental shelves located along eastern boundary currents occupy relatively small volumes of the world’s oceans, yet are responsible for a large proportion of global primary production. The Oregon coast is among these ecosystems. Recent analyses of dissolved oxygen at shallow depths in the water column has suggested increasing episodes of...
