  • Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

    Creator:
    Barnard, Holly Rene
    Abstract:
    The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

  • The inherent optical properties of the oceans: from closure to prediction

    Creator:
    Barnard, Andrew Heath
    Abstract:
    Precise in situ measurement of the spectral absorption and scattering coefficients in several regions has revealed patterns in the distribution of the inherent optical properties on spatial scales that were previously unobtainable. The precision of the measurements was found to be consistent and unbiased across a variety of oceanic regimes...

  • The Relevance of Sexual Health Websites for African American Youth

    Creator:
    Barnard, Ke'ala J.
    Abstract:
    School-based comprehensive sex education (CSE) can reduce adolescent sexual health problems. However, only 49-55% of adolescents receive CSE that meets national standards. African American youth (AAY), particularly males, are less likely to receive CSE. AAY evidence a high prevalence of STIs/teen pregnancy. Internet-based CSE offers a supplemental option. We examined...

  • Stem sapwood water transport and storage strategies in three conifers from contrasting climates

    Creator:
    Barnard, David M.
    Abstract:
    The state of Oregon has two distinct climate types bisected by the crest of the Cascade Mountain range. The western side of the Cascades experiences high levels of precipitation and mild temperatures due to the maritime influence of the Pacific Ocean, while the eastern side lies in the rain shadow...

  • Geneticist L.C. Dunn : politics, activism, and community

    Creator:
    Gormley, Melinda (Melinda Brooke)
    Abstract:
    L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....

  • Projected wave conditions in the Eastern North Pacific under the influence of two CMIP5 climate scenarios

    Creator:
    Erikson, L. H., Hegermiller, C. A., Barnard, P. L., Ruggiero, P., and van Ormondt, M.
    Abstract:
    Hindcast and 21st century winds, simulated by General Circulation Models (GCMs), were used to drive global- and regional-scale spectral wind-wave generation models in the Pacific Ocean Basin to assess future wave conditions along the margins of the North American west coast and Hawaiian Islands. Three-hourly winds simulated by four separate...

    Barnard, Andrew H., Zaneveld, J. Ronald V., and Pegau, W. Scott
    Abstract:
    We tested closure between in situ radiometric and absorption coefficient measurements by using a nearly backscattering-independent remote-sensing reflectance model that employs the remote-sensing reflectance at three wavelengths. We show that only a small error is introduced into the closure model when the proper functional relationships of f/Q and the backscattering...

  • Influence of surface waves on measured and modeled irradiance profiles

    Creator:
    Zaneveld, J. Ronald V., Boss, Emmanuel, and Barnard, Andrew
    Abstract:
    Classical radiative transfer programs are based on the plane-parallel assumption. We show that the Gershun equation is valid if the irradiance is averaged over a sufficiently large area. We show that the equation is invalid for horizontal areas of the order of tens of meters in which horizontal gradients of...
