  • The biology of a shallow-water methane vent

    Creator:
    Juhl, Andrew R.
    Abstract:
    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...

  • Continuous seismic profiling investigation of the southern Oregon continental shelf between Cape Blanco and Coos Bay

    Creator:
    Mackay, Angus James
    Abstract:
    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...

  • Conserved properties in the metagenome of a large bacterioplankton population

    Creator:
    Wilhelm, Larry John
    Abstract:
    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...

  • Relationships between thermal and electrical conductivities of ocean sediments and consolidated rocks

    Creator:
    Hutt, Jeremy Reinboth
    Abstract:
    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...
