  • Shear and convective turbulence in a model of thermohaline intrusions

    Creator:
    Mueller, Rachael
    Abstract:
    Thermohaline interleaving is an important mechanism for laterally fluxing salt, heat, and nutrients between oceanic water masses. Interleaving is driven by a release of potential energy resulting from the vastly differing diffusivities of heat and salt in seawater. The flows are composed of stacked intrusions that flux more buoyant and...

  • Sedimentary texture--a key to interpret deep-marine dynamics

    Creator:
    Allen, David William
    Abstract:
    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. Deductions concerning...

  • Chile trench : extensional rupture of oceanic crust and the influence of tectonics on sediment distribution

    Creator:
    Schweller, W. J. (William John)
    Abstract:
    Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...

  • Long wavelength gravity anomalies and implications concerning a descending lithospheric slab in the Pacific Northwest

    Creator:
    MacFarlane, William Thomas
    Abstract:
    The thermal regime of a postulated descending lithospheric slab is calculated. The gravity anomaly associated with such a structure is large in amplitude and long in wavelengh. Observed free-air gravity anomalies in the Pacific Northwest do not indicate a gravitational effect due to a descending slab. Two hypothetical compensation models...

  • Turbulence in sheared, salt-fingering favorable environment

    Creator:
    Kimura, Satoshi
    Abstract:
    Instability and turbulence in sheared, salt-fingering favorable stratification are studied using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable stratification is gravitationally stable, because the unstable vertical gradient of salinity is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering instability can occur at the interface of these different water-masses....

  • Morphology, shallow structure, and evolution of the Peruvian continental margin, 6⁰ to 18⁰ S

    Creator:
    Masias Echegaray, Juan Antonio
    Abstract:
    Detailed bathymetric survey data were collected along the Peruvian continental margin and were compiled by the author and other investigators to construct a new bathymetric map for the area between 6° to 18°S latitude. Based on this map and individual bathymetric profiles, the continental shelf topography is essentially flat. Four...

  • Nonlinear internal waves on the continental shelf

    Creator:
    Shroyer, Emily L.
    Abstract:
    The properties and evolution of nonlinear internal waves (NLIWs) depend upon the background conditions within which waves form, propagate, and dissipate. As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged...

  • The feeding habits of three species of lantern-fishes (Myctophidae) off central Oregon

    Creator:
    Tyler, Harry Raymond, Jr.
    Abstract:
    The feeding habits of the lanternfishes Tarletonbeania crenularis, Diaphus theta and Stenobrachius leucopsarus were studied by analyzing 1,735 stomachs from 54 collections from the slope waters off Newport, Oregon. Forty-one taxa of food items were identified. Euphausiids (Euphausia pacifica), copepods (Calanus spp. and Metridia lucens) and amphipods (Parathemisto pacifica) were...

  • Swimbladder morphology and buoyancy of Northeastern Pacific myctophids

    Creator:
    Butler, John Lawton
    Abstract:
    Of the common adult lanternfishes found off Oregon, two species have fat-invested swimbladders (Stenobrachius leucopsarus Eigenmann and Eigenmann 1890 and Stenobrachius nannochir Gilbert 1891), two species have reduced swimbladders (Lampanyctus ritteri Gilbert 1915 and Lampanyctus galis Gilbert 1891), two species have gas-filled swimbladders ((Protomyctophum thomp soni (Chapman 1944)) and (Protomyctophum...
