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...

A case for trading risk in complex conceptual design trade studies

Creator:: Van Bossuyt, Douglas L., Tumer, Irem Y., and Wall, Stephen D.
Abstract:: Complex conceptual system design trade studies traditionally consider risk after a conceptual design has been created. Further, one person is often tasked with collecting risk information and managing it from each subsystem. This paper proposes a method to explicitly consider and trade risk on the same level as other important...

A comparison of methods for the measurement of the absorption coefficient in natural waters

Creator:: Pegau, W. Scott, Cleveland, Joan S., Doss, W., Kennedy, C. Dan, Maffione, Robert A., Mueller, James L., Stone, R., Trees, Charles C., Weidermann, Alan D., Wells, Willard H., and Zaneveld, J. Ronald
Abstract:: In the spring of 1992 an optical closure experiment was conducted at Lake Pend Oreille, Idaho. A primary objective of the experiment was to compare techniques for the measurement of the spectral absorption coefficient and other inherent optical properties of natural waters. Daily averages of absorption coefficients measured using six...

A comparison of techniques for magnetotelluric response function estimation

Creator:: Jones, Alan G., Chave, Alan D., Egbert, Gary D., Auld, Don, and Bahr, Karsten
Abstract:: Spectral analysis of the time-varying horizontal magnetic and electric field components yields the magnetotelluric (MT) impedance tensor. This frequency dependent 2x2 complex tensor can be examined for details which axe diagnostic of the electrical conductivity distribution in the Earth within the relevant (frequency dependent) inductive scale length of the surface...

A doubled down invasion of the northeast Pacific by the Asian mud shrimp, Upogebia major and its coevolved bopyrid isopod parasite, Orthione griffenis

Creator:: Chapman, John W., Li, Jingchun, McGowan, Michael F., Breitenstein, Ralph A., Appy, Ralph, Hieb, Kathryn A., Piotrowski, Christina N., and Elder, Leanne E.
Abstract:: Dramatic declines of the native northeast Pacific mud shrimp, Upogebia pugettensis over the last three decades have occurred in response to intense infestations by the Asian bopyrid isopod parasite, Orthione griffenis, that was introduced in the 1980s. We report herein the arrival of the Asian mud shrimp, Upogebia major, in...

A freely falling probe for small-scale temperature gradients

Creator:: Caldwell, Douglas R., Wilcox, Steve D., and Matsler, Mark
Abstract:: A light, simple, and fairly inexpensive hand-launched freely falling probe for measuring temperature microstructure was built. The circuitry operates under pressure in a Freon environment; low-power integrated circuits are used as components. The probe is assembled from plastic pipe and fittings and recovered with monofilament fishing line. Standard XBTs are...

A model to predict stream water temperature across the conterminous USA

Creator:: Segura, Catalina, Caldwell, Peter, Sun, Ge, McNulty, Steve, and Zhang, Yang
Abstract:: Stream water temperature (tₛ) is a critical water quality parameter for aquatic ecosystems. However, tₛ records are sparse or nonexistent in many river systems. In this work, we present an empirical model to predict tₛ at the site scale across the USA. The model, derived using data from 171 reference...

A Modification of the Garrett–Munk Internal Wave Spectrum

Creator:: Levine, Murray D.
Abstract:: The Garrett–Munk (GM) spectrum continues to be a useful description of the oceanic internal wave field. However, there are several inconsistencies and ambiguities that make it difficult to use in comparing internal wave fields at different latitudes, stratifications, and water depths. A modified spectral formulation is presented that treats three...

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...

A new genus and species of Macrochelidae (Acari: Mesostigmata) associated with the Texas leafcutting ant, Atta texana (Buckley) in Louisiana, USA

Creator:: Krantz, Gerald W. and Moser, John C.
Abstract:: Adults and nymphs of a new genus and species of the family Macrochelidae are described from detritus cavities of the leafcutting ant, Atta texana. This new species is notable in having peritremes with no posterior loop, a series of small subterminal teeth on the fixed cheliceral digit rather than the...
