A modified law-of-the-wall applied to oceanic bottom boundary layers

Creator:: Perlin, A., Moum, James N., Klymak, J. M., Levine, Murray D., Boyd, Timothy John, 1958-2013, and Kosro, P. Michael
Abstract:: Near the bottom, the velocity profile in the bottom boundary layer over the continental shelf exhibits a characteristic law-of-the-wall that is consistent with local estimates of friction velocity from near-bottom turbulence measurements. Farther from the bottom, the velocity profile exhibits a deviation from the law-of-the-wall. Here the velocity gradient continues...

Sediment delivery from the Fly River tidally dominated delta to the nearshore marine environment and the impact of El Ninõ

Creator:: Ogston, Andrea S., Sternberg, Richard W., Nittrouer, Charles A., Martin, D. Preston, Goni, Miguel A., and Crockett, John S.
Abstract:: In tidally dominated deltas, sediment discharged from the river sources must transit through an estuarine region located within the distributary channels, where particle pathways can undergo significant transformations. Water column profiles and time series data were collected in the distributaries and shallow nearshore region offshore of the Fly River, Papua...

Pervasive mantle plume head heterogeneity: Evidence from the late Cretaceous Caribbean-Colombian oceanic plateau

Creator:: Kerr, Andrew C, Tarney, John, Kempton, Pamela D., Spadea, Piera, Nivia, Alvaro, Marriner, Giselle F., and Duncan, Robert A.
Abstract:: In SW Colombia picritic pillow lavas and tuffs, as well as breccias composed of picritic clasts, occur interspersed with basalts of the Central Cordillera and represent accreted portions of the similar to 90 Ma Colombian/Caribbean oceanic plateau (CCOP). We present new geochemical data for these picrites and high-MgO basalts from...

Persistence of soil organic matter in eroding versus depositional landform positions

Creator:: Berhe, Asmeret Asefaw, Harden, Jennifer W., Torn, Margaret S., Kleber, Markus, Burton, Sarah D., and Harte, John
Abstract:: Soil organic matter (SOM) processes in dynamic landscapes are strongly influenced by soil erosion and sedimentation. We determined the contribution of physical isolation of organic matter (OM) inside aggregates, chemical interaction of OM with soil minerals, and molecular structure of SOM in controlling storage and persistence of SOM in different...

A nested grid model of the Oregon Coastal Transition Zone: Simulations and comparisons with observations during the 2001 upwelling season

Creator:: Springer, S. R., Samelson, Roger M., Allen, John S., Egbert, Gary D., Kurapov, Alexander, Miller, Robert N., and Kindle, J. C.
Abstract:: The Oregon Coastal Transition Zone (OCTZ) extends several hundred kilometers offshore where shelf flows interact with the northern California Current. A primitive-equation numerical ocean model is used to study the upwelling circulation in this region from 1 May to 1 November 2001. This OCTZ model obtains initial and boundary conditions...

Mapping the U.S. West Coast surface circulation: A multiyear analysis of high‐frequency radar observations

Creator:: Kim, Sung Yong, Terrill, Eric J., Cornuelle, Bruce D., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The nearly completed U.S. West Coast (USWC) high-frequency radar (HFR) network provides an unprecedented capability to monitor and understand coastal ocean dynamics and phenomenology through hourly surface current measurements at up to 1 km resolution. The dynamics of the surface currents off the USWC are governed by tides, winds, Coriolis...

Magnetotelluric observations across the Juan de Fuca subduction system in the EMSLAB project

Creator:: Wannamaker, Philip E., Booker, John R., Filloux, Jean H., Jones, Alan G., Jiracek, George R., Chave, Alan D., Tarits, Pascal, Waff, Harve S., Egbert, Gary D., Young, Charles T., Stodt, John A., Martinez, Mario G., Law, Lawrie K., Yukutake, Takesi, Segawa, Jiro S., White, Anthony, and Green, A.W.
Abstract:: A magnetotelluric (MT)transect has been obtained near latitude 45øN from the active Juan de Fuca Spreading center, across the subduction zone and Cascades volcanic arc, and into the back arc Deschutes Basin region. This paper presents the MT data set and describes its major characteristics as they pertain to the...

Introduction to special section : Coastal Advances in Shelf Transport

Creator:: Barth, John A. and Wheeler, Patricia A.
Abstract:: The Coastal Ocean Advances in Shelf Transport (COAST) program conducted an interdisciplinary study of coastal upwelling off central Oregon during summer 2001. Two intensive field efforts during May–June and August 2001 were coordinated with ocean circulation, ecosystem, and atmospheric modeling of the region. A primary goal was to contrast the...

Forcing a three-dimensional, hydrostatic, primitive-equation model for application in the surf zone : 1. formulation

Creator:: Newberger, P. A. and Allen, John S.
Abstract:: An Eulerian analysis for wave forcing of three-dimensional (3D) wave-averaged mean circulation in the surf zone is presented. The objective is to develop a dynamically consistent formulation for applications in a 3D primitive equation model. The analysis is carried out for the case of shallow-water linear waves interacting with wave-averaged...

Modeling of ecosystem processes on the Oregon shelf during the 2001 summer upwelling

Creator:: Spitz, Yvette, Allen, John S., and Gan, J.
Abstract:: Three-dimensional ecosystem response to wind forcing on the continental shelf off Oregon is studied using a five-component nitrogen-based ecosystem model coupled to a high-resolution circulation model. We investigate, in particular, the influence of timedependent winds and alongshore variations in shelf topography for summer 2001 during the time period of the...
