  • Modeling global hammond landform regions from 250-m elevation data

    Creator:
    Karagulle, Deniz, Frye, Charlie, Sayre, Roger, Breyer, Sean, Aniello, Peter, Vaughan, Randy, and Wright, Dawn
    Abstract:
    Landforms are natural features on the Earth’s surface that both reflect and shape geophysical and ecological process. The result is a defining part of landscapes that so often impact on human perception and interactions with environment. Blascyznki (1997) defines landforms as, “specific geomorphic features on the surface of the Earth,...

  • Mock modularity of the M-d-rank of overpartitions

    Creator:
    Jennings-Shaffer, Chris and Swisher, Holly
    Abstract:
    We investigate the modular properties of a new partition rank, the M-d-rank of overpartitions. In fact this is an infinite family of ranks, indexed by the positive integer d, that gives both the Dyson rank of overpartitions and the overpartition M-2-rank as special cases. The M-d-rank of overpartitions is the...

  • A three-dimensional mapping of the ocean based on environmental data

    Creator:
    Wright, Dawn J.
    Abstract:
    The existence, sources, distribution, circulation, and physicochemical nature of macroscale oceanic water bodies have long been a focus of oceanographic inquiry. Building on that work, this paper describes an objectively derived and globally comprehensive set of 37 distinct volumetric region units, called ecological marine units (EMUs). They are constructed on...

    Abstract:
    The Roger Revelle Commemorative Lecture Series was created by the Ocean Studies Board of the National Academies in honor of Roger Revelle to highlight the important links between ocean sciences and public policy. Dawn J. Wright, the eighteenth annual lecturer, spoke on April 28, 2017, at the Smithsonian National Museum...

    Creator:
    Wright, Dawn J.
    Abstract:
    This perspectives paper uses the seminal Goodchild (1992) article as a lens through which to review and reflect upon several longstanding issues that have influenced the field of geographic information science in the past and will continue to be important at least into the next decade. Under the category of...

  • Toward a digital resilience

    Creator:
    Wright, Dawn J.
    Abstract:
    As we contend with human impacts on the biosphere, there is rightfully a great emphasis now on community adaptation and resilience to climate change. Recent innovations in information technologies and analyses are helping communities to become more resilient. However, not often discussed in this vein is a path toward digital...

  • Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

    Creator:
    Ye, T. Z. and Jayawickrama, K. J. S.
    Abstract:
    Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

  • Internal Tides and Turbulence along the 3000-m Isobath of the Hawaiian Ridge

    Creator:
    Lee, Craig M., Sanford, Thomas B., Kunze, Eric, Nash, Jonathan D., Merrifield, Mark A., and Holloway, Peter E.
    Abstract:
    Full-depth velocity and density profiles taken along the 3000-m isobath characterize the semidiurnal internal tide and bottom-intensified turbulence along the Hawaiian Ridge. Observations reveal baroclinic energy fluxes of 21 ± 5 kW m⁻¹ radiating from French Frigate Shoals, 17 ± 2.5 kW m⁻¹ from Kauai Channel west of Oahu, and...

  • Stable isotopes (¹⁸O/¹⁶O) and ⁸⁷Sr/⁸⁶Sr ratios in pore fluids of the Chile Triple Junction accretionary prism : implications for diagenesis and fluid migration

    Creator:
    Zheng, Yan, Froelich, Philip N., Torres, Marta E., and Dia, Aline N.
    Abstract:
    Oxygen and strontium isotopic composition of sedimentary pore fluids obtained by drilling at the Chile Triple Junction have been used to obtain information on the diagenesis and transport mechanisms of fluids. Samples were collected from three sites located on an east-west transect of the pre-collision zone (Sites 859, 860, and...

  • Subsurface temperatures beneath Southern Hydrate Ridge

    Creator:
    Tréhu, Anne Martine
    Abstract:
    During Ocean Drilling Program Leg 204, 80 in situ measurements of subseafloor temperature were made; 68 of these showed good frictional pulses on insertion and extraction from the seafloor and were used to constrain the subsurface temperature. Considering uncertainties from various sources, uncertainties in the in situ temperatures are estimated...
