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...

Error spectrum for the global M₂ ocean tide

Creator:: Ray, Richard D., Eanes, R. J., Egbert, Gary D., and Pavlis, N. K.
Abstract:: The most accurate determinations of the global ocean tides are currently based on altimeter measurements made by the Topex/Poseidon satellite. The error spectrum corresponding to the M₂ tidal solution is here estimated, primarily by inverse methods and secondarily by simple differencing in flatter than tidal signal spectrum, and it exceeds...

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...

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,...

Data report : major-element chemistry of Hole 896a glass

Creator:: Fisk, Martin R., McNeill, Andrew W., Teagle, Damon A. H., Furnes, Harald, and Bach, Wolfgang
Abstract:: Ocean Drilling Program Hole 896A (1°13.01'N, 83°43.39'W) is in 3440 m of water east of the Galapagos Platform in the equatorial eastern Pacific Ocean. At this site in 5.9 Ma crust, basement rocks were recovered over the depth range of 195.1 meters below seafloor (mbsf) to 469 mbsf. These rocks...

Geological and geochemical contraints on the isotopic composition of interstitial waters from the Hydrate Ridge region, Cascadia Continental margin

Creator:: Tomaru, A. M., Matsumoto, R., Torres, Marta E., and Borowski, Walter S.
Abstract:: The isotopic compositions of interstitial waters collected from Hydrate Ridge during Ocean Drilling Program Leg 204 were measured to evaluate the fluid evolution of this accretionary prism. At shallow depths, the dissolved Cl- concentrations and δD and δ¹⁸O values of the interstitial water reflect changes in the salinity and the...

Investigation of microorganisms and DNA from subsuface thermal water and rock from the east flank of Juan de Fuca Ridge

Creator:: Fisk, Martin R., Thorseth, Ingunn H., Urbach, Ena, and Giovannoni, Stephen J.
Abstract:: During Leg 168 of the Ocean Drilling Program, basalts were recovered by drilling and subsurface water was collected with a water sampling tool at Hole 1026B on the east flank of Juan de Fuca Ridge. Microorganisms were found in both types of samples. The microorganisms in the basalt appear to...
