  • Indian horticulture west and northwest of the Colorado River

    Creator:
    Forbes, Jack D.
    Abstract:
    It has generally been assumed by historians and anthropologists that the indigenous groups living to the west and northwest of the Colorado River were non-horticultural with three or four exceptions: some horticulture among the eastern-most Kamia, among the Chemehuevi who settled at a late date along the Colorado River, and...

  • Some Environmental Consequences of Vertical Migration in Marine Zooplankton

    Creator:
    Miller, Charles B.
    Abstract:
    The spatial distribution of plankton is highly aggregated, so one might expect that a vertically migrating animal enters a biotic environment that is markedly different each evening and that the changes in environment between daylight periods spent at depth are equally great. To measure the extent of these changes, as...

  • Aerosol and solar radiation in Britain

    Creator:
    Unsworth, Michael H. and Monteith, J. L.
    Abstract:
    The irradiance of the solar beam was measured on cloudless days at Sutton Bonington in the English Midlands and at sites in north-west Scotland. Total and diffuse fluxes were also measured on some days. An attenuation coefficient for aerosol Ta was defined by S(Ta) = S(o) exp ( - Tam)...

  • Distribution of suspended matter in the Panama basin

    Creator:
    Plank, William S., Zaneveld, J. Ronald, and Pak, Hasong
    Abstract:
    The distribution of suspended matter in the Panama basin was determined by means of light scattering and Coulter counter measurements on water samples collected at 50 hydrographic stations. The observed distribution indicates three probable sources of suspended matter: (1) the surface waters throughout the basin; (2) erosion and runoff from...

  • The Cromwell Current on the east side of the Galapagos Islands

    Creator:
    Pak, Hasong and Zaneveld, J. Ronald V.
    Abstract:
    Observations made during October and December 1971 on the Yaloc 71 Cruise of Oregon State University indicate the presence of the Cromwell Current on the east side of the Galapagos Islands. Light scattering, particle size distribution, nutrients, and standard hydrographic parameters were measured in water samples collected at 154 stations....

  • Failure of interbreeding between Atlantic and Pacific populations of the marine calanoid copepod Acartia clausi Giesbrecht

    Creator:
    Carrillo B.-G., Enrique, Miller, Charles B., and Wiebe, Peter H.
    Abstract:
    An attempt has been made to interbreed populations of Acartia clausi from Woods Hole, Massachusetts, and Yaquina Bay, Oregon. Individuals from these populations are morphologically similar, but differ somewhat in size. Cultures from both sources produced many successive generations in the laboratory, but interbreeding with production of viable offspring did...

  • Long-wave radiation at the ground

    Creator:
    Unsworth, Michael H. and Monteith, J.L.
    Abstract:
    The apparent emissivity of the atmosphere ϵ, defined as the ratio of incoming long-wave radiation to black-body radiation at screen temperature Tₐ, was measured under clear skies in the English Midlands and in the Sudan. At a zenith angle Z the emissivity was given by ϵ(Z) = a + bIn(usec...

  • Workshop on problems of assessing populations of nekton

    Creator:
    Pearcy, William G.
    Abstract:
    A workshop was held in Santa Barbara, California, associated with assessing the populations of nekton animals such as squids, shrimps and fishes. Sessions four major methods of assessing nekton populations: (1) Net collections (2) Acoustics (3) Egg/larval surveys (4) Visual methods, remote sensing and feeding habit studies An attempt was...

  • Patterns of vertical distribution and migration of zooplankton at Ocean Station “P”

    Marlowe, Christopher J. and Miller, Charles B.
    Abstract:
    Stratified bongo net samples taken at depths between 0 and 500 m at Ocean Station “P” in the subarctic Pacific in early July 1971 have been analyzed to determine the vertical structure of the zooplankton community. Distributions for 99 categories of animals have been grouped by factor analysis into five...
