  • Albacore oceanography off Oregon : 1970

    Creator:
    Pearcy, William G.
    Abstract:
    During July 1970, albacore boats trolling surface jigs (jig boats) had record catches in an area off the mouth of the Columbia River. The jig fishery declined suddenly in late July and was poor throughout the remainder of the summer. No obvious oceanographic changes were correlated with these drastic changes...

  • Distribution and abundance of small flatfishes and other demersal fishes in a region of diverse sediments and bathymetry off Oregon

    Creator:
    Pearcy, William G.
    Abstract:
    Demersal fishes were sampled at seven stations located inshore of Heceta Bank, on Oregon's continental shelf, over a 2-yr period with a 3-m beam trawl designed to catch small fiatfishes. Two general assemblages of fishes were recognized: a shallow water 74-102 m), sandy-bottom association where Pacific sanddab, Citharichthys sordidus,was numerically...

    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...

  • Spectral distribution of solar radiation. I: direct radiation

    Creator:
    McCartney, H. A. and Unsworth, Michael H.
    Abstract:
    Measurements of the spectral distribution of direct solar radiation, made in both wide and narrow wavebands, are reported. The measurements suggest that the wavelength dependence of aerosol attenuation in central England, in summer, can generally be described by a power law with wavelength exponent of about 1.7. Attenuation of visible...
