  • Upwelling, Columbia River plume and albacore tuna

    Creator:
    Pearcy, William G. and Mueller, James L.
    Abstract:
    Infrared radiometers, photographs, and a multispectral scanner were used in a remote sensing study of the ocean off Oregon during the summer of 1969. Upwelling appeared on infrared temperature maps as a zone of cold water along the coast and Columbia River water appeared as a warm water "plume". Sharp...

  • Theoretical Dependence of the Near-Asymptotic Apparent Optical Properties on the Inherent Optical Properties of Sea Water

    Creator:
    Beardsley, George F., Jr. and Zaneveld, J. Ronald V.
    Abstract:
    The apparent optical properties of sea water are a set of measurables that describe the geometry of the submarine light field. These properties are related to the inherent optical properties—the volume attenuation coefficient and the volume scattering function—through the process of radiative transfer. A numerical approximation to the equation of...

  • Depth Distribution of Oceanic Shrimps (Decapoda ; Natantia) off Oregon

    Creator:
    Pearcy, William G. and Forss, Carl A.
    Abstract:
    Sixteen species of oceanic shrimps, seven Penaeidea and nine Caridea, appeared in 244 collections made within the upper 1500 m at one station in the northeast Pacific off Oregon. Most of the species were primarily mesopelagic in distribution. The most abundant species, Sergestes similis, was the only shrimp common in...

  • Modulation Transfer Function of Sea Water

    Creator:
    Zaneveld, J. Ronald V. and Beardsley, George F., Jr.
    Abstract:
    The modulation transfer function (MTF) of a simple submarine viewing situation is computed as a function of range and sea-water properties. For the cases considered, we found that the MTF follows the simple exponential law, exp(-ω/ω₀), where ω is the spatial frequency in lines/deg and where ω₀ is a complicated...

  • Partial differential equations of Sobolev-Galpern type

    Creator:
    Showalter, R. E.
    Abstract:
    A mixed initial and boundary value problem is considered for a partial differential equation of the form Muₜ(x, t)+Lu(x, t)=0, where M and L are elliptic differential operators of orders 2 m and 2l, respectively, with m ≤ l. The existence and uniqueness of a strong solution of this equation...
