Patterns in benthic coral reef communities at Pearl and Hermes Atoll along a wave exposure gradient

Creator:: Page-Albins, Kimberly N., Vroom, Peter S., Hoeke, Ronald, Albins, Mark A., and Smith, Celia M.
Abstract:: This study compares percent cover of benthic organisms at the species level at Pearl and Hermes Atoll (PHA), the largest atoll in the Northwestern Hawaiian Islands, in order to determine 1) the degree of difference among sites, 2) whether wave exposure zones explain observed patterns in benthic community structure, and...

Amount and distribution of coarse woody debris in pine ecosystems of north-western Spain, Russia and the United States

Creator:: Herrero, Celia, Krankina, Olga, Monleon, Vicente J., and Bravo, Felipe
Abstract:: The quantity and characteristics of coarse woody debris (CWD) were examined in four distinct pine ecosystems of north-western (NW) Spain, NW Russia and the NW USA. The average CWD volume and biomass ranged from 3.76 m³ ha⁻¹, 1.55 Mg ha⁻¹ in pine plantations in NW Spain to 24.86 m3 ha⁻¹,...

Microzooplankton grazing impact in the Bering Sea during spring sea ice conditions

Creator:: Sherr, Barry F., Ross, Celia, and Sherr, Evelyn B.
Abstract:: Microzooplankton grazing impact on phytoplankton in the Bering Sea during spring was assessed in 2008, 2009 and 2010 using two-point dilution assays. Forty-nine experiments were completed in a region encompassing shelf to slope waters, including the 70 m line along the edge of the shelf. A variety of conditions were...

Trapping and hysteresis in two-phase flow in porous media: A pore-network study

Creator:: Joekar-Niasar, V., Doster, F., Armstrong, R. T., Wildenschild, D., and Celia, M. A.
Abstract:: Abstract: Several models for two-phase flow in porous media identify trapping and connectivity of fluids as an important contribution to macroscale hysteresis. This is especially true for hysteresis in relative permeabilities. The trapping models propose trajectories from the initial saturation to the end saturation in various ways and are often...

The M₂ Internal Tide off Oregon: Inferences from Data Assimilation

Creator:: Kurapov, Alexander L., Egbert, Gary D., Allen, J. S., Miller, Robert N., Erofeeva, Svetlana Y., and Kosro, P. M.
Abstract:: A linearized baroclinic, spectral-in-time tidal inverse model has been developed for assimilation of surface currents from coast-based high-frequency (HF) radars. Representer functions obtained as a part of the generalized inverse solution show that for superinertial flows information from the surface velocity measurements propagates to depth along wave characteristics, allowing internal...

Estimates of the 10-m Neutral Sea Surface Drag Coefficient from Aircraft Eddy-Covariance Measurements

Creator:: Vickers, Dean, Mahrt, Larry, and Andreas, Edgar L.
Abstract:: The 10-m neutral drag coefficient (C[subscript DN10]) over the sea is calculated using a large observational dataset consisting of 5800 estimates of the mean flow and the fluxes from aircraft eddy-covariance measurements. The dataset includes observations from 11 different experiments with four different research aircraft. One of the goals is...

Energetics of M₂ Barotropic-to-Baroclinic Tidal Conversion at the Hawaiian Islands

Creator:: Carter, G. S., Merrifield, M. A., Becker, J. M., Katsumata, K., Gregg, M. C., Luther, D. S., Levine, M. D., Boyd, Timothy John, 1958-2013, and Firing, Y. L.
Abstract:: A high-resolution primitive equation model simulation is used to form an energy budget for the principal semidiurnal tide (M₂) over a region of the Hawaiian Ridge from Niihau to Maui. This region includes the Kaena Ridge, one of the three main internal tide generation sites along the Hawaiian Ridge and...

Solid Solution Studies of Layered Honeycomb-Ordered Phases O3-Na3M2SbO6 (M = Cu, Mg, Ni, Zn)

Creator:: Schmidt, Whitney, Berthelot, Romain, Sleight, A. W., and Subramanian, M. A.
Abstract:: Complete solid solutions with the composition Na₃M₂₋ₓM’ₓSbO₆ where M, M’ = Cu, Mg, Ni, Zn have been synthesized by conventional solid state techniques and were investigated using X-ray diffraction, magnetism and optical measurements. All compositions crystallize in a monoclinic unit cell and exhibit a layered structure with a honeycomb cationic...

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...

Scatterometer-Based Assessment of 10-m Wind Analyses from the Operational ECMWF and NCEP Numerical Weather Prediction Models

Creator:: Chelton, Dudley B and Freilich, Michael H.
Abstract:: Wind measurements by the National Aeronautics and Space Administration (NASA) scatterometer (NSCAT) and the SeaWinds scatterometer on the NASA QuikSCAT satellite are compared with buoy observations to establish that the accuracies of both scatterometers are essentially the same. The scatterometer measurement errors are best characterized in terms of random component...
