The processes responsible for transporting and depositing thick
sections of coarse-grained terrigenous clastics on the abyssal floor
and for forming associated sedimentary structures are still conjectural.
Many workers attribute coarse deep-sea sediments and their
probable lithified equivalent, the graywackes of flysch deposits to
some type of density movement.

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...
A study was undertaken in Yaquina Bay, Oregon during the
summer of 1964 to determine the distribution and the factors affecting
the distribution of the polychaete worm, Nephtys caecoides,
Hartman, 1938, in the estuary.
This organism has a continuous distribution from offshore to
a point approximately eight kilometers into the...
